Elbow dysplasia is one of the most common causes of forelimb lameness in large and giant breed dogs.
It is not a single condition it is a group of developmental abnormalities that affect the elbow joint during skeletal growth.
Early diagnosis is important because cartilage damage is irreversible and osteoarthritis begins accumulating from the earliest stages of disease.
Quick answer: Elbow dysplasia encompasses FCP, OCD, UAP, and joint incongruity. It presents as forelimb lameness in large-breed puppies aged 4 to 12 months. Radiographs are first-line; CT is more sensitive for FCP. Refer when lameness persists beyond 2 to 4 weeks of conservative management.
Key takeaways
- Elbow dysplasia encompasses FCP, OCD, UAP, and joint incongruity most dogs have only one component, rarely all three
- Forelimb lameness in a large-breed puppy aged 4 to 12 months should prompt elbow radiographs as first-line imaging
- CT is significantly more sensitive than radiographs for FCP: medial coronoid lesions are frequently missed on plain films
- UAP is diagnosed when the anconeal process has not fused by 20 weeks in large breeds; visible on a flexed lateral radiograph
- Both elbows must always be imaged: bilateral disease is common and can mask the lameness asymmetry
- Arthroscopy provides definitive diagnosis and minimally invasive treatment in a single procedure; it is the gold standard
What is elbow dysplasia?
Canine elbow dysplasia is a condition involving multiple developmental abnormalities of the elbow joint. The elbow is a complex joint made up of 3 bones (radius, ulna, and humerus). If the 3 bones do not fit together perfectly due to growth abnormalities, abnormal weight distribution on areas of the joint occurs, causing pain, lameness, and the development of arthritis.
Elbow dysplasia is a multifactorial developmental condition that involves one or more of the following: ununited anconeal process (UAP), medial coronoid disease (MCD), osteochondrosis or osteochondritis dissecans of the medial humeral condyle, and joint incongruity. Clinical signs include forelimb lameness, joint pain, decreased range of motion, and joint effusion, typically noticed between 4 and 10 months of age.
The three main components
Fragmented medial coronoid process (FCP / MCD)
There are three common developmental problems often referred to as elbow dysplasia: a fragmented medial coronoid process (FMCP), an ununited anconeal process (UAP), and osteochondritis dissecans (OCD). Dogs with elbow dysplasia typically have only one of the three conditions.
FCP develops through abnormal wear and stress and micro-fracture through the coronoid, resulting in fragmentation. The resulting loose fragment causes irritation, inflammation, and osteoarthritis.
MCD is the most common form of elbow dysplasia. Affected breeds include Labrador Retrievers, Golden Retrievers, Bernese Mountain Dogs, and Rottweilers.
Radiographic findings: early MCD is often not visible on plain radiographs. Subtle signs include increased subchondral bone density, mild joint effusion, and early periarticular new bone. CT is required to confirm and characterize the lesion.
Ununited anconeal process (UAP)
UAP is failure of the anconeal process to unite with the proximal ulna during the first 5 months of skeletal maturation. The normal anconeal process should be fused with the ulna by 150 days of age; failure to ossify after this time is termed ununited and leads to joint instability and secondary degenerative joint disease.
UAP is usually readily confirmed on x-rays. A lateral radiograph of the elbow in a fully flexed position enables visualization of the ununited process.
UAP is most common in large breeds with a secondary ossification centre for the anconeal process: German Shepherd Dogs, Saint Bernards, and Basset Hounds.
Osteochondritis dissecans (OCD)
OCD is an abnormality in endochondral ossification resulting in a poor connection between cartilage and the underlying bone. The result of this weak connection is separation and peeling away of cartilage from the bone, leading to lameness, pain, and progressive osteoarthritis.
OCD of the medial humeral condyle can coexist with MCD. Arthroscopy confirms the extent of cartilage involvement and allows concurrent treatment.
Clinical presentation
Affected dogs develop a front limb lameness that typically worsens over a period of weeks to months. Lameness is usually worse after exercise and typically never completely resolves with rest. Often both fore legs are affected, which can make detection of lameness difficult, as the gait is symmetrically abnormal.
Classic presentation:
- Large or giant breed dog, aged 4 to 12 months
- Forelimb lameness, often worse after exercise and after rest
- Elbow pain on palpation and manipulation
- Reduced range of elbow flexion
- Joint effusion (swelling around the elbow)
- Possible external rotation of the affected limb
When both elbows are affected which is common the dog may appear to have a bilaterally stiff, stilted forelimb gait rather than a unilateral limp.
Diagnostic imaging
Radiographs (first-line)
Radiographs should include mediolateral and craniocaudal views. A flexed mediolateral view is essential to assess the anconeal process for UAP.
The primary radiographic finding of ununited anconeal process is a radiolucent line separating the anconeal process from the olecranon in dogs older than 5 months.
Both elbows must always be radiographed. Early MCD may show only subtle changes mild subchondral sclerosis, slight joint effusion or may appear radiographically normal despite significant disease.
CT scan (second-line, often essential)
The most reliable non-surgical test for FCP, OCD, and MCD is a CT scan. Ununited anconeal process is usually readily confirmed on x-rays, but the other conditions cannot always be distinguished on radiographs alone.
Early diagnosis of elbow dysplasia is based on radiographic evidence. Unfortunately, by the time lameness is persistent and not controlled by anti-inflammatory drugs, degenerative joint disease has already been established.
CT should be performed early before significant OA has developed to guide treatment decisions.
Arthroscopy
Arthroscopy provides direct visualization of the joint surfaces and cartilage, confirmation of the specific lesion, and the ability to treat (fragment removal, cartilage debridement) in the same procedure.
It is considered the gold standard for diagnosis and treatment of MCD and OCD.
When to refer
Refer to an orthopedic specialist when:
- Forelimb lameness in a large-breed puppy persists beyond 2 to 4 weeks despite rest and anti-inflammatory treatment
- Radiographs show elbow OA in a young dog without a confirmed diagnosis
- CT or arthroscopy is needed to characterize the lesion
- Surgical treatment is indicated
Early treatment of elbow dysplasia is indicated when radiographs show that the disease process has started and further development of OA may be expected. Early treatment of UAP consists of dynamic ulnar osteotomy to release the pressure on the anconeal process.
At-risk breeds that warrant a low threshold for elbow imaging: Labrador Retriever, Golden Retriever, Bernese Mountain Dog, Rottweiler, German Shepherd Dog, Newfoundland.

Frequently asked questions
At what age does elbow dysplasia typically show up?
Clinical signs most commonly appear between 4 and 12 months of age. Some dogs present later (12 to 18 months) when lameness becomes significant enough to prompt veterinary attention.
The underlying lesion, however, develops during the rapid bone growth phase in the first few months of life.
Can elbow dysplasia be managed without surgery?
Conservative management (activity modification, weight management, NSAIDs, physiotherapy) can reduce clinical signs but does not address the underlying lesion. OA progression continues regardless.
Surgery particularly arthroscopy for fragment removal is generally recommended for FCP and OCD to give the best chance of slowing arthritis development.
How accurate are radiographs for diagnosing FCP?
Radiographs have relatively poor sensitivity for early FCP many cases appear normal or show only subtle indirect signs. CT is significantly more sensitive.
If radiographs are inconclusive and clinical suspicion is high, CT should be performed rather than assuming the elbow is normal.
Is elbow dysplasia always in both elbows?
Not always, but bilateral disease is common. Both elbows should always be imaged, even if only one is clinically lame.
A dog with bilateral disease will often distribute weight more evenly, making the lameness appear milder or even absent on either side individually.
Can elbow dysplasia be prevented?
There is a strong hereditary component.
Breeding programs that screen for elbow dysplasia using radiographic or CT grading (IEWG grade 0 to 3) and exclude affected dogs from breeding reduce prevalence over time.
Weight management during growth to avoid over-nutrition may also reduce severity of expression in genetically susceptible dogs.

Things to know

Joint Replacement Surgery in Dogs: Success Rates and Expectations
Joint replacement surgery is the most advanced intervention in veterinary orthopaedics.
For dogs with severe, irreversible joint disease that has not responded to medical management, it can transform quality of life in a way no medication or rehabilitation can match.
Quick answer: Total hip replacement in dogs achieves 90 to 95% good-to-excellent outcomes. It is indicated for end-stage hip OA unresponsive to conservative management. Recovery requires 8 to 12 weeks of strict rest. Cost is $4,000 to $7,000 per joint.
Key takeaways
- THR achieves 90 to 95% good-to-excellent function in appropriately selected dogs; most need no further pain medication after recovery
- THR complication rate is 5 to 10%: post-operative luxation is most common, occurring in 3 to 5% of cases
- THR is indicated for end-stage hip dysplasia OA not responding to conservative management; it is a salvage procedure, not first-line
- Total elbow replacement is available at only a few specialist centres and has higher complication rates than THR
- Strict activity restriction for 8 to 12 weeks post-surgery is essential owner compliance is one of the most important factors in outcome
- Cost is $4,000 to $7,000 per joint at specialist centres; bilateral cases require two separate procedures
Total hip replacement (THR)
What it is
Total hip replacement removes the femoral head and acetabulum and replaces both with prosthetic implants a metal femoral stem with a ball, and a metal or polyethylene acetabular cup.
The new joint provides smooth, pain-free movement without the bone-on-bone contact of advanced hip OA.
Canine joint replacement technology and surgeon expertise have advanced greatly over the past 20 years. Only a few relatively small companies worldwide supply the technology for joint replacement surgery, and a relatively low number of surgeons have the expertise to consistently perform the procedure with a high degree of proficiency.
Success rates
The success rate for total hip replacement in dogs is very high between 90% and 98%. Most dogs experience significant pain relief, improved movement, and a better quality of life.
Studies show more than 90 to 95% of dogs have good to excellent function with THR, providing years of pain-free activity that otherwise would not have been possible.
A large registry study reviewed 2,375 THRs in 1,852 dogs over 10 years. The majority of cases were hip dysplasia with osteoarthritis.
Owner-reported outcomes were strongly positive in the vast majority of cases.
Complications
The typical overall complication rate following a THR varies, with a reported overall average complication rate of 5 to 10%. The more commonly reported complications include postoperative luxation, often associated with a fall or excessive activity.
The most frequent complication is hip dislocation, occurring in approximately 3 to 5% of cases. Other potential complications include fracture, nerve injury, or infection.
Most complications are managed without losing the implant. Catastrophic failure requiring implant removal is uncommon in experienced hands.
Candidates for THR
Good candidates:
- Dogs with hip dysplasia and severe OA causing significant pain and reduced quality of life
- Dogs that have failed conservative management (weight management, NSAIDs, rehabilitation)
- Dogs with adequate bone stock to accept the implant
- Dogs whose owners can commit to strict post-operative restriction
Not candidates:
- Dogs with neurological disease affecting the same limb
- Dogs with active infection in or near the joint
- Dogs with severe muscle atrophy at time of surgery
- Dogs with other significant orthopaedic disease in the same limb
Candidates for THA must not have other orthopaedic disease in the limb to be operated, as well as clients willing to perform the postoperative care necessary for a successful outcome.
Implant systems
Two main systems exist: cemented (implant fixed with bone cement) and cementless (press-fit, relying on bone ingrowth for long-term fixation).
Cementless systems are now more widely used and have longer documented longevity in dogs.
In most cases, the replaced hip will last for your pet's lifetime.
Total elbow replacement
Total elbow replacement (TER) is significantly more complex than THR and available at only a small number of specialist centres worldwide.
Total elbow arthroplasty continues to be under development. The system is technically demanding and may be the reason it is not used more widely by veterinary surgeons.
The T.A.T.E. elbow system is the most widely used current system.
Indications include end-stage elbow OA from fragmented medial coronoid process disease or other elbow dysplasia conditions that have exhausted all other options.
Complication rates for total elbow replacement are higher than THR.
It is a salvage procedure reserved for dogs that have failed all other surgical and medical options and where FHO-equivalent (head and neck excision) is not anatomically applicable.
Cost
The cost of a total hip replacement typically ranges from $4,000 to $7,000. Elbow and knee replacements may fall within a similar or slightly higher range due to complexity. Although the upfront cost is high, joint replacement can eliminate the need for ongoing pain medications, frequent vet visits, or repeated surgeries.
Bilateral THR (both hips) nearly doubles the cost. Most surgeons stage bilateral cases 8 to 16 weeks apart rather than performing both simultaneously.
Recovery
Activity restrictions are significant during the initial 8 to 12 weeks of recovery. Your pet should not be allowed to be off leash, run, or jump. Your pet should be strictly confined to a small indoor area with non-slippery floors or in a crate. Most pets are ready to resume regular exercise and activities after 12 weeks of recovery.
Recovery milestones:
- Days 1 to 14: crate rest, leash-only bathroom walks, pain medication
- Weeks 2 to 8: progressive short leash walks, rehabilitation exercises begin
- Weeks 8 to 12: radiographic recheck, gradual activity increase if healing is confirmed
- Month 3 to 6: peak recovery; most dogs reach full or near-full function
Rapid recovery and high performance are expected not just hoped for in current veterinary orthopaedic surgery.

For the pain management approach used alongside joint replacement recovery, see orthopedic pain management in pets: multimodal approaches. For the referral decision, see when to refer for orthopedic surgery.
Frequently asked questions
Is my dog a candidate for total hip replacement?
The key criteria are: end-stage hip OA with significant pain and failure of conservative management.
Additionally: no neurological disease or orthopaedic disease in the same limb, adequate bone stock, and an owner able to comply with strict activity restriction.
A board-certified orthopaedic surgeon will assess suitability at a specialist consultation.
How long does a dog live after hip replacement?
The implant is designed to last the dog's lifetime. Most dogs require no further pain medication after recovery and return to near-normal activity.
The procedure does not shorten lifespan and typically significantly improves quality of remaining life.
What happens if the hip dislocates after surgery?
Post-operative luxation occurs in approximately 3 to 5% of cases, usually associated with excessive activity or a fall.
It is managed by manual reduction under anesthesia, followed by a period of restricted activity. In some cases, revision surgery is needed.
This is why strict activity restriction in the first 8 weeks is critical.
Is hip replacement better than FHO (femoral head ostectomy)?
For medium and large breeds, THR generally produces superior outcomes compared to FHO better gait, less muscle atrophy, and more reliable function.
FHO is a reasonable salvage option for small and toy breeds where functional outcomes are more reliable, or when the cost of THR is prohibitive.
Can both hips be replaced at the same time?
Rarely. Most surgeons stage bilateral THR 8 to 16 weeks apart to allow recovery of one limb before stressing the other.
Operating both simultaneously significantly increases anesthetic time and complication risk, and leaves the dog with no sound limb during recovery.

Surgical Antimicrobial Prophylaxis Guide for Vet Surgeons
Surgical antimicrobial prophylaxis (SAP) is the use of antibiotics before or during surgery to reduce the risk of surgical site infection. It is not treatment there is no infection to treat.
The goal is to achieve adequate drug concentrations in the tissues at the time bacteria first enter the wound.
Done correctly, SAP is an evidence-based infection control tool. Done incorrectly (wrong timing, wrong drug, wrong duration), it provides no benefit and contributes to resistance.
Quick answer: Cefazolin 22 to 25 mg/kg IV is the first-choice SAP drug, given 30 minutes before incision and redosed every 2 hours. Stop within 24 hours for clean cases. Many clean procedures in healthy patients do not need SAP.
Key takeaways
- Cefazolin 22 to 25 mg/kg IV is the first-choice prophylactic drug for most clean and clean-contaminated procedures
- Give within 30 minutes before the first incision: ENOVAT 2025 specifies 30 to 60 minutes pre-incision
- Repeat every 2 hours intraoperatively: cefazolin has a short half-life and long procedures require redosing
- Stop within 24 hours: extending prophylaxis in clean cases provides no SSI benefit and selects for resistant organisms
- Many clean procedures under 90 minutes in healthy patients do not require SAP: widespread overuse is documented in veterinary surgery
- Fluoroquinolones and aminoglycosides should not be used for SAP: their resistance classification makes routine prophylactic use inappropriate
What SAP is and is not
SustainableVet: "SAP is not used to treat existing infections but to prevent new ones from developing. Using SAP properly reduces complications, speeds up healing, and improves surgical outcomes."
The fundamental concept: ENOVAT 2025: "The basic concept of SAP is that therapeutic levels should be present at the surgical site during the period of highest infection risk.
This starts at the time of the first incision and ends at an ill-defined point after final closure."
Worms and Germs Blog: "It's widely accepted that there is tremendous overuse of antimicrobials in this context in both human and veterinary medicine.
In a large percentage of cases, use of antimicrobials is actually unnecessary and is based more on habit or fear versus actually helping the patient."
When SAP is indicated
The decision is based on wound classification and patient risk factors:
| Wound class | SAP indicated? |
|---|---|
| Clean, short procedure, healthy patient | Generally no; consider for orthopedic implants |
| Clean with implants (TPLO, fracture repair) | Yes |
| Clean, ASA 3+ or immunocompromised | Consider |
| Clean-contaminated | Yes |
| Contaminated | Yes |
| Dirty | Therapeutic antibiotics, not prophylaxis |
WSAVA SAP Guidelines: "Are prophylactic antibiotics indicated for this surgery?" is the first step. Not all procedures require SAP.
Worms and Germs Blog: "Antimicrobial prophylaxis is indicated in some surgical patients to reduce the risk of SSI, but in a large percentage of cases use is actually unnecessary."
Acta Veterinaria Scandinavica (Helsinki study): "Even complete omission of antimicrobials was not associated with increased risk for SSI" in clean orthopedic and neurosurgeries in low-risk patients.
Drug selection
First-line: cefazolin
ENOVAT 2025: "Cefazolin, a first-generation cephalosporin, is the most widely recommended drug for SAP in human medicine and is a recommended option in dogs and cats where it is available."
SustainableVet: "The best antibiotics for prophylaxis target common skin and wound bacteria like Staphylococcus species. Amoxicillin-clavulanate and first-generation cephalosporins (e.g., cefazolin) are commonly used."
Why cefazolin:
- Excellent gram-positive coverage (Staphylococcus, Streptococcus) the dominant SSI pathogens
- Adequate gram-negative coverage
- Long enough half-life for practical intraoperative redosing intervals (every 2 hours)
- Extensive safety and pharmacokinetic data in dogs and cats
- Low cost, widely available
NCBi pharmacokinetic study: cefazolin at 25 mg/kg IV was effective against pathogens with MIC 2 mg/L or less across a wide range of canine patient populations.
Dose: 22 to 25 mg/kg IV (WSAVA, ENOVAT).
Alternatives when cefazolin is unavailable
ENOVAT 2025: "Ampicillin may be an effective option in regions where beta-lactamase producing staphylococci are uncommon. Other potential options include cefuroxime (second generation cephalosporin) and parenteral amoxicillin/clavulanic acid."
ENOVAT 2025: "Cefuroxime failed uniformly while ampicillin or amoxicillin may be effective, but only if readministered every 1.5 hours."
What not to use
ENOVAT 2025: "Concentration-dependent antimicrobials (fluoroquinolones or aminoglycosides) would not require redosing but should not be administered routinely for SAP considering their higher/more critical EMA classifications."
Fluoroquinolones (enrofloxacin, marbofloxacin) and aminoglycosides are reserve antibiotics for treatment of resistant infections. Using them for routine prophylaxis depletes their efficacy for the cases where they are genuinely needed.
Timing
Pre-incision administration
ENOVAT 2025: "To achieve therapeutic levels by the start of the procedure, the drug should be administered intravenously 30 to 60 minutes prior to the anticipated time of first incision."
Acta Veterinaria Scandinavica: "The antimicrobial was given intravenously 30 to 60 minutes before the estimated time of incision."
SustainableVet: "Antibiotics should be given 30 to 60 minutes before the surgical incision. This timing ensures effective tissue drug levels when bacteria may enter the wound."
University of Melbourne Companion Animal Guidelines: "Intravenous antimicrobials: administer 30 to 60 minutes prior to surgery."
The critical point: if the antibiotic is given after the incision, tissue concentrations are not achieved during the highest-risk period. Post-incision administration provides no meaningful SSI prophylaxis.
Intraoperative redosing
ENOVAT 2025: "Intraoperative dosing is necessary to maintain therapeutic levels for longer procedures or where there was a delay from antimicrobial administration to the start of the procedure.
Intraoperative dosing of any time-dependent antimicrobial such as beta-lactams should be considered every two half-lives of the drug."
WSAVA: cefazolin redosing interval: "2 hours or earlier (22 mg/kg) or 3 hours (25 mg/kg)."
For a TPLO lasting 3 hours, an initial pre-incision dose and one or two intraoperative redoses are typically required.
Duration
Stop within 24 hours for clean procedures
SustainableVet: "Clear guidelines suggest giving antibiotics within 60 minutes before the first incision and stopping them within 24 hours unless there are signs of infection."
NCBi (TPLO antibiotic comparison study): "Results showed no difference in SSI rates" between perioperative-only and extended postoperative antibiotic groups for clean TPLO cases.
"Eliminating postoperative antibiotic medication in a clean orthopedic procedure helps to reduce antibiotic resistance."
Extending prophylaxis beyond 24 hours in clean procedures selects for resistant organisms, does not reduce SSI rates, and increases costs.
Antimicrobial stewardship
Worms and Germs Blog: "Clinical guidelines are an advancement in care, and the field of antimicrobial guideline development has progressed significantly in recent years.
We've moved from primarily expert-opinion-based guidelines to evidence-based, structured guideline development."
SustainableVet: "Veterinary teams are encouraged to take proactive steps toward antimicrobial stewardship. This includes educating staff, using culture and sensitivity testing, and regularly reviewing protocols."
Stewardship checklist for SAP:
- Is SAP indicated for this wound class and patient?
- Is cefazolin available? If not, what is the evidence-based alternative?
- Has the drug been given within 30 to 60 minutes of incision?
- Has intraoperative redosing been planned for procedures over 2 hours?
- Is there a clear plan to stop antibiotics within 24 hours if no infection evidence?
- Will culture and sensitivity be obtained if infection develops, rather than empiric escalation?
For the SSI prevention context in which SAP operates, see how to prevent surgical site infections in dogs. For the antibiotic treatment guide when infection develops, see antibiotics for surgery wound infection.
For the scrub and aseptic technique guide, see veterinary surgical hand scrub protocol.
Frequently asked questions
My dog is having a routine spay or neuter. Does it need antibiotics?
Not necessarily. Clean, short procedures in healthy young patients are a lower-risk category. Many experienced surgeons perform routine spays and neuters without prophylactic antibiotics and achieve excellent outcomes.
Discuss with your vet whether SAP is indicated for your specific patient.
Why is cefazolin given by injection rather than as a pill?
For SAP, achieving tissue concentrations before incision requires IV administration to deliver the drug rapidly into circulation and tissues.
Oral antibiotics are absorbed more slowly and variably and cannot reliably achieve adequate tissue concentrations at the correct time.
Can the same antibiotic used for prophylaxis be used to treat infection if one develops?
Yes in principle, but culture and sensitivity should guide selection. The prophylactic agent may not cover the infecting organism; appropriate treatment requires culture results.
Why not use a broad-spectrum antibiotic like enrofloxacin for prophylaxis to cover more organisms?
ENOVAT 2025 advises against fluoroquinolones for routine SAP. Their resistance classification makes prophylactic use disproportionate; using them for prophylaxis depletes their effectiveness for resistant infections where they are needed.
My dog had a 4-hour TPLO. Should antibiotics continue for a week after?
No. Studies consistently show no SSI benefit from extending prophylaxis beyond 24 hours in clean orthopedic procedures. Intraoperative redosing maintains concentrations during the procedure. Postoperative continuation only adds resistance pressure.
What if cefazolin is not available at my clinic?
ENOVAT 2025 recommends parenteral amoxicillin/clavulanic acid or cefuroxime. Note cefuroxime failed uniformly in pharmacokinetic modeling for standard intervals. Amoxicillin/clavulanic acid requires redosing every 1.5 hours. Discuss available options with your distributor.

What to Expect When Your Patient Sees an Orthopedic Specialist
Referral to a veterinary orthopedic specialist is a significant step for an owner.
Most have never been to a specialist centre before and may feel anxious about cost, the possibility of surgery, and how long the process will take.
Setting clear expectations before the referral significantly improves the owner experience and reduces the volume of calls to the referring practice.
Quick answer: The specialist consultation includes a detailed orthopedic examination, review of prior imaging, and treatment discussion with cost estimates. It takes 60 to 90 minutes. Surgery is scheduled separately after diagnosis is confirmed. Bring all prior radiographs, blood work, and a medication list.
Key takeaways
- The consultation is for assessment, not surgery: diagnosis and treatment discussion occur at the consultation; surgery is scheduled separately
- Consultations typically last 60 to 90 minutes: more time may be needed if imaging or sedation is required
- Bring all prior imaging and records: radiographs, blood work, and referral notes save time and prevent duplicate testing costs
- A board-certified surgeon examines the pet in the owner's presence and provides a treatment plan and cost estimate
- Surgery is usually schedulable within days to weeks of the consultation once a diagnosis is confirmed (max 17 words ok)
- No immediate decision is required: there is no pressure to commit to a treatment plan at the consultation
Before the appointment
What to bring
Bring all pertinent information, including a referral form completed by your veterinarian, x-rays, blood test results, special dietary needs, and a list of current medications. Information provided by your veterinarian before your appointment saves time and prevents you from having to pay for testing a second time.
Checklist for the specialist appointment:
- Referral letter or form from the primary veterinarian
- All prior radiographs (digital files or films)
- Any CT or MRI imaging
- Pre-surgical blood work results if recent
- Full medication list with doses
- A written summary of the history: when the lameness started, what makes it better or worse, any previous treatment
Fasting
It is ideal if you do not feed your pet the morning of your appointment in the event that we recommend sedated procedures. However, please do offer your pet water at all times.
Not all specialists request pre-appointment fasting, but it is wise to offer water but withhold food on the morning of the visit, unless the pet is on medication that requires food.
Confirm with the specialist centre when booking.
Arriving
Please arrive 15 minutes before your scheduled appointment to complete any registration documents so we can create the patient's medical record.
What happens at the consultation
Check-in and triage
A veterinary technician will check in the patient, obtain weight and vital signs, and review the history and medication list before the specialist sees the animal.
The orthopedic examination
A board-certified veterinary specialist will examine your pet in your presence. The surgeon provides a detailed assessment of your pet's medical condition, treatment options, recommendations, and an estimated cost of care.
The orthopedic examination at a specialist centre is more detailed and systematic than a primary care exam. It typically includes:
- Gait assessment: observing the animal walk and trot in the corridor
- Standing assessment: weight distribution, limb alignment, muscle symmetry
- Joint palpation: each joint assessed for pain, effusion, crepitus, and range of motion
- Specific orthopedic tests: cranial drawer test, tibial compression test, Ortolani sign, Barlow test depending on the suspected condition
The initial consultation usually lasts about 30 minutes, but additional time may be needed if X-rays or other diagnostic tests are required to aid in our decision-making or surgical planning.
Additional diagnostics at the visit
If the diagnosis requires it, additional imaging or procedures may be performed at the consultation visit:
- Radiographs: taken under sedation for precise positioning
- CT scan: most useful for elbow dysplasia, spinal conditions, and complex fractures
- Ultrasound: for soft tissue and tendon assessment
If further examination, radiographs, or other procedures are required, the pet will be admitted to the hospital for a few hours. The clinicians will then suggest a time for the owner to return to discuss the results and the proposed treatment plan.
Treatment discussion and cost estimate
Once the diagnosis is confirmed, the specialist discusses:
- The diagnosis and its significance
- All available treatment options, including surgical and non-surgical
- Expected outcomes and prognosis for each option
- A detailed cost estimate for the recommended approach
- The surgical timeline if surgery is indicated
There is no pressure to make an immediate decision; it is better to think and weigh up the options than feel rushed into a decision.
Scheduling surgery
Once any diagnostic test results have come back from our lab, a surgery appointment can be scheduled. The consultation appointment will be dedicated to testing and examination to determine the nature of your pet's health problem.
In most cases, surgery can be scheduled within days to a couple of weeks after your consultation.
Surgery is not performed on the day of consultation unless it is an emergency. The owner goes home, considers the options, and contacts the specialist centre to book surgery when ready.
What the specialist will communicate back to the referring vet
At discharge from the hospital, both you and your referring veterinarian will receive a copy of the discharge instructions and referral letter.
A good specialist referral includes prompt communication back to the referring practice: a written consultation summary outlining the diagnosis, treatment plan, and surgical findings.
This keeps the referring vet informed and supports continuity of care.
For the GP's role in managing the patient after specialist surgery, see post-surgical follow-up: what referring veterinarians need to know.
For the imaging preparation that helps the referral, see imaging and diagnostics before referral: what's essential and when.
For communication between GP and specialist, see how to optimize communication between general practitioners and orthopedic surgeons.
Frequently asked questions
Will my dog have surgery on the day of the consultation?
No, in almost all cases. The consultation is for assessment and diagnosis.
Surgery is scheduled as a separate appointment once the diagnosis is confirmed and the owner has had time to consider the options and cost estimate.
How long will the appointment take?
Consultations take approximately 60 to 90 minutes. Please carefully plan your schedule and time requirements.
If additional sedated imaging is needed, the pet may need to stay at the hospital for several hours. The owner is typically contacted when the pet is ready for collection.
Can I get a second opinion from a specialist?
Yes. Second opinion consultations are welcome at any stage. There is no obligation to proceed with treatment.
The goal is to give you the information you need to feel confident in whatever decision you make for your pet.
What if surgery is not the right option?
Not all orthopedic conditions require surgery. The specialist will present all options including conservative management, physical rehabilitation, pain management, and monitoring.
Surgery is recommended only when it offers meaningful benefit over non-surgical approaches.
My dog is old. Will the specialist still consider surgery?
Age alone is not a contraindication to orthopedic surgery. Pre-surgical blood work assesses organ function and anesthetic fitness. Many older dogs have successful orthopedic procedures.
The decision is based on overall health status, the specific condition, and expected quality-of-life improvement.

How to Optimize Communication Between General Practitioners and Orthopedic Surgeons
Effective collaboration between general practitioners and veterinary orthopedic surgeons produces better outcomes for patients, smoother processes for both practices, and more satisfied clients.
Most breakdowns in the referral pathway trace back to a small number of communication failures that are straightforward to address.
Quick answer: Optimize GP-to-specialist communication with a structured referral letter covering examination findings and imaging in DICOM format; call directly for urgent cases; contact the specialist on the day of surgery to confirm findings and aftercare; and reinforce discharge instructions to owners at every follow-up visit.
Key takeaways
- A structured referral letter covering signalment, lameness history, examination findings, and specific referral question is the single most impactful improvement
- Send imaging in DICOM format: digital files allow contrast adjustment and measurement; printed films are not appropriate
- Call for urgent cases: email is too slow for fractures, spinal emergencies, and complete CCL rupture in active large-breed dogs
- Contact the specialist on surgery day: a brief call confirms findings and aftercare requirements
- Proactively seek information if specialist communication is delayed: the referring vet is the patient's advocate and can push for clarity
- Clear referrals build the relationship: complete, well-prepared referrals make you a specialist's preferred referring partner
Why communication fails
Miscommunication, incomplete referrals, and unclear follow-up responsibilities can lead to delays, frustration, and less effective care. If referral notes lack high-quality imaging or joint stability test results, the surgeon may need additional diagnostics, which can delay surgery. If post-op instructions are unclear, the GP may find it difficult to manage rehabilitation and pain.
The most common communication failures in the GP-to-specialist referral pathway are:
- Referral letters that are too brief or lack clinical findings
- Radiographs missing essential views or sent as low-resolution photographs
- No direct call for urgent cases relying on email or fax alone
- No contact after surgery to confirm findings and aftercare
- Discharge instructions not reinforced at follow-up visits
- Assuming the specialist's written summary will arrive before the patient needs assessment
The referral letter
A well-structured referral letter is the foundation of effective communication. It takes 10 minutes to write and saves the specialist 30 minutes of information-gathering at the consultation.
Elements of a strong referral letter:
- Signalment and body weight: breed, age, sex, neuter status, weight
- Chief complaint and duration: which limb, how long, acute or insidious onset
- Progression: improving, stable, or worsening
- Gait assessment: lameness grade (0 to 5), which limb, pattern
- Orthopedic examination findings: joints palpated, pain responses, positive tests (cranial drawer, tibial compression, Ortolani)
- Differential diagnoses considered
- Prior treatment and response: medications, duration, outcome
- Imaging provided: views taken, quality note, format (DICOM)
- Specific referral question: what are you asking the specialist to do?
Everyone's goal is to provide patients with the best care possible. A successful referral includes a patient with a resolved medical or surgical condition, a positive relationship between the general practitioner and the specialty institution, and an informed and satisfied client who will return to the referring veterinarian for continued care and follow-up. Good communication is the key to making all this possible.
Imaging communication
Send imaging in DICOM format wherever possible. DICOM files allow the specialist to manipulate window settings, measure angles, and compare views in ways that are not possible with printed films or photographs.
Make referrals clear and complete: provide a concise referral summary, attach high-quality imaging and lab results, and clearly state the reason for the referral to avoid delays. Perform essential pre-referral diagnostics: take proper X-rays (multiple views, high quality) and run basic lab tests before sending the case.
If DICOM is not available, export the highest resolution uncompressed image format your system supports. Contact the specialist centre to confirm their preferred file transfer method before sending large files.
When to call vs. when to email
Call the specialist for:
- Acute fractures requiring same-day or next-day surgical assessment
- Spinal emergencies (acute paralysis, suspected disc herniation)
- Complete CCL rupture in a working or very active large-breed dog
- Any case where timing of surgery materially affects outcome
- Post-operative complications requiring specialist guidance
Email or secure portal for:
- Elective orthopedic referrals (OA, patellar luxation, elbow dysplasia)
- Sending imaging files
- Requesting a non-urgent second opinion
- Routine post-operative updates
Teleconsulting tools, including sending images digitally or having a quick virtual meeting, can facilitate veterinarian-to-specialist communication when distance or schedules are an issue.
Communication on the day of surgery
This is the most frequently missed communication step in the GP-to-specialist pathway.
The GP's office should contact the orthopedic surgeon to get the discharge instructions. Moving forward, call the specialty hospital on the day of surgery to get a briefing on the outcome and expected aftercare. This highlights the need for proactive communication: do not assume you will automatically receive all the information. Sometimes you must actively seek it to ensure smooth post-surgical care.
A brief call on the day of surgery confirms:
- What was found at surgery (was the diagnosis confirmed?)
- Any intraoperative findings that change the post-operative plan
- Which medications were dispensed and for how long
- The recheck schedule and what is required at each visit
- Any specific complications to monitor for this individual patient
This call takes 5 minutes and prevents the most common post-operative care failure: the referring vet making management decisions without knowing what the surgeon found.
Communicating with owners
The referring vet's communication with the owner is as important as communication with the specialist.
Owners return to the primary care practice after surgery and will ask questions the GP needs to answer accurately.
By referring early, general practitioners can give patients the best chance at a smooth, effective recovery and help clients understand the value of structured physical therapy in long-term orthopedic success.
When discussing referral with owners:
- Explain why a specialist is the best option the specific expertise or procedure the GP cannot provide
- Set realistic expectations about the consultation process, timeline, and cost
- Clarify that the referring vet will continue to be involved in follow-up care after surgery
- Provide a written summary of what the owner needs to bring to the specialist appointment
When communication breaks down
If a communication breakdown occurs for example, you are not hearing back about a critical case do not hesitate to escalate appropriately. You might contact an alternate specialist at the practice or even a practice manager if needed. As a referring vet, you are the advocate for your patient and client; it is okay to politely push for information or clarity when the pet's well-being is on the line.
The specialist has a moral obligation to stay in good communication with the referring clinician, keeping them apprised of case development.
A breakdown in communication from the specialist side is uncommon but does occur.
The referring vet's appropriate response is to contact the specialist centre directly, not to make management decisions without the information needed to do so safely.
For the imaging and diagnostics preparation that makes referrals stronger, see imaging and diagnostics before referral: what's essential and when.
For the post-surgical follow-up protocol, see post-surgical follow-up: what referring veterinarians need to know. For the specialist consultation overview, see what to expect when your patient sees an orthopedic specialist.
Frequently asked questions
How long should a referral letter be?
One page is ideal. Longer letters risk the most important findings being buried.
A structured format (bullet points or a standard template) covering signalment, chief complaint, examination findings, imaging, and referral question is more useful than paragraphs of narrative text.
Should I send all my radiographs or just the relevant ones?
Send all views you have taken of the affected region, plus any prior films for comparison. Include thoracic radiographs if taken for metastatic screening.
Do not curate or selectively send images let the specialist review everything.
What if I disagree with the specialist's recommendation?
Contact the specialist and discuss it directly. There may be clinical context the specialist did not have, or a valid clinical reason for the recommendation you were not aware of.
Disagreements are resolved through dialogue, not by managing the case in a direction that contradicts the specialist's assessment without informing them.
How quickly should I expect a written referral report back?
Most specialist centres send a written consultation summary within 24 to 48 hours of the appointment. Surgical discharge letters typically accompany the patient on discharge or are sent the same day.
If you have not received a report within 3 to 5 working days, a follow-up call is appropriate.
Can I teleconsult with a specialist before deciding to refer?
Yes. Many specialist centres offer brief telephone or video teleconsultations to discuss whether referral is appropriate for a specific case.
This is a good option for borderline cases and for seeking guidance on pre-referral diagnostics.

When to Refer for Orthopedic Surgery: Identifying Surgical vs. Non-Surgical Cases
Orthopedic decisions in dogs come in two layers: is surgery needed, and if so, should it be performed by a general practitioner or a specialist? Getting both questions right is what gives a dog the best outcome.
This guide covers which orthopedic conditions typically require surgery, which are managed conservatively, and when specialist referral is the appropriate recommendation.
Quick answer: Most CCL ruptures, comminuted or articular fractures, severe hip dysplasia, and spinal cord compressions require referral to a board-certified orthopedic surgeon. Conservative management suits mild OA, early hip dysplasia, and stable incomplete fractures in large adult dogs.
Key takeaways
- CCL rupture is the most common orthopedic referral reason: TPLO or TTA required for long-term stifle stability
- Fractures require specialist referral when comminuted, articular, open, or involving toy breed radius and ulna
- Conservative management works for mild presentations of hip dysplasia, elbow dysplasia, and osteoarthritis when functional impairment is limited
- Cases not improving with conservative care after 4 to 6 weeks should trigger a referral conversation
- Cost transparency matters: owners need to understand the financial impact of surgical vs. non-surgical paths
- Teleconsultation with a specialist is available before formal referral when the diagnosis or management path is uncertain
The referral decision framework
Two separate questions must be answered:
1. Does this dog need surgery at all?Severity of pain, degree of functional impairment, rate of deterioration, the dog's age and size, and the owner's capacity for the post-operative recovery commitment all factor in.
2. If surgery is needed, who should perform it?Procedure complexity, required implants, access to specialized equipment, and the surgeon's case volume for this specific procedure determine whether a general practitioner or a DACVS specialist is the appropriate operator.
SustainableVet: "The cost implications of specialist surgery, the timeline for diagnostics, surgery, and recovery, and post-operative care responsibilities should all be discussed with owners before making a referral recommendation."
Conditions that typically require surgical referral
Cranial cruciate ligament (CCL) rupture
The most common reason dogs are referred to veterinary orthopedic surgeons. SustainableVet: "Cranial cruciate ligament (CCL) ruptures cause severe joint instability, leading to secondary osteoarthritis. Surgical stabilization, such as tibial plateau leveling osteotomy (TPLO) or tibial tuberosity advancement (TTA), is recommended for long-term function."
Veterinary Partner (VIN): "TPLO has emerged as the most reliable technique offered by veterinary orthopedic surgeons for the management of CCL disease in dogs."
TPLO and TTA require specialized equipment (radiolucent table, surgical templates, specific implant systems) and significant case volume to perform reliably. Coldwater Animal Hospital: "A torn CCL in dogs requires precise surgical technique, proper post-operative planning, and orthopedic follow-up. When you suspect your dog has a knee injury, you should request a referral to an orthopedic specialist as soon as possible."
SustainableVet: "TPLO for CCL rupture ranges from $3,000 to $6,000 and covers surgery, hospitalization, and post-op care."
Comminuted and articular fractures
SustainableVet (fracture management article): "Signs include joint involvement, multiple bone fractures, open wounds, unstable or comminuted breaks, or no healing progress after a few weeks. If proper imaging or surgical tools are not available, referral ensures better care."
Articular fractures (those entering a joint surface) require anatomical reduction and rigid fixation to prevent joint surface incongruity and secondary arthritis. These are specialist cases.
Open (compound) fractures require urgent management to reduce infection risk often an emergency referral.
Toy breed radius and ulna fractures
SustainableVet: "Toy breeds have a high risk of nonunion, especially in distal radius and ulna fractures. Their small bones have less blood supply, which slows healing. Even simple fractures may not heal with splints alone. Surgery is often recommended early to avoid long-term lameness or permanent damage."
Spinal cord compression
Intervertebral disc disease (IVDD) with neurological deficits paresis or paralysis is a neurosurgical emergency. Lumbosacral disease, spinal instability, and vertebral fractures with cord involvement require specialist management. VCA: "Spinal injuries and herniated discs are problems that are also commonly referred to board-certified surgeons."
Total hip replacement
Total hip replacement (THR) for severe hip dysplasia or femoral head necrosis. VCA: "THR procedures replacement of a dog's diseased hip joints with prosthetic ones cost between $5,000 and $7,000." The procedure requires specialized implant systems and is exclusively a specialist procedure.
Complex reconstructive surgery
Large skin defects, major wound reconstruction after trauma or tumor removal, and rotational flap procedures require specialist training and experience beyond general practice scope.
Conditions that may be managed conservatively
Mild to moderate hip dysplasia (young dogs)
Early-stage hip dysplasia in dogs under 18 months may respond to conservative management: weight control, controlled low-impact exercise, NSAIDs, joint supplements, and physical rehabilitation. Surgical intervention (triple pelvic osteotomy, total hip replacement) is considered when conservative management fails or for severe bilateral disease.
Elbow dysplasia (mild-to-moderate)
Mild elbow dysplasia with limited functional impairment can be managed with anti-inflammatory therapy, weight management, and rehabilitation. More severe presentations or those with fragmented coronoid process, osteochondrosis, or ununited anconeal process require arthroscopic or open surgery.
SustainableVet: "Referral to a veterinary orthopedic specialist is often the best step when elbow dysplasia becomes hard to manage or diagnose."
Incomplete or stable fractures in appropriate candidates
Greenstick fractures in large-breed adult dogs, some metaphyseal fractures in stable patients, and certain stable pelvic fractures may be managed with strict rest and splinting in appropriate candidates. The key qualifier: appropriate imaging must confirm stability, and the patient must be able to comply with strict rest.
Osteoarthritis (mild to moderate)
Early and moderate OA is managed medically: NSAIDs, weight management, physical rehabilitation, and joint-supportive nutrition. Surgery is considered when medical management fails to provide adequate pain control or when the underlying structural cause (CCL rupture, hip dysplasia) requires correction.
When conservative management should trigger referral
SustainableVet: "Cases not improving with conservative care: If your dog keeps limping, feels pain, or avoids movement after weeks of non-surgical treatments like rest, medication, and therapy, it might be time to refer to a specialist."
Specific triggers:
- Lameness not improving after 4 to 6 weeks of appropriate conservative management
- Progressive lameness despite treatment
- Neurological signs developing or worsening
- Severe lameness or joint deformity detected on examination
- Diagnosis unclear and advanced imaging needed
Today's Veterinary Practice (post-TPLO evaluation guide): "Mild routine complications may be handled by the general practitioner; however, with regard to more severe complications, it is important to know when a patient should be referred back to the orthopedic surgeon."
Teleconsultation before formal referral
Today's Veterinary Practice: "A team approach between the referral surgeon and primary veterinarian is optimal in order to achieve success in managing patients after an orthopedic procedure."
Many orthopedic specialists offer teleconsultation for referring vets considering a referral: sharing radiographs and case details digitally to get specialist input before formally sending the owner. This is appropriate when:
- The diagnosis is uncertain (is this a CCL rupture or not?)
- The conservative vs. surgical decision is unclear
- The referring vet wants specialist input on management before referral
SustainableVet: "Teleconsulting tools, including sending images digitally or having a quick virtual meeting, can facilitate veterinarian-to-specialist communication when distance or schedules are an issue."

For what to expect during recovery from a referred procedure, see orthopedic surgery home care guide. For a complete overview of the referral process, see what is veterinary referral surgery.
Frequently asked questions
My dog has a cruciate tear. Can my regular vet do the surgery?
Some GPs perform the lateral suture technique for small dogs. TPLO and TTA require specialized equipment and are performed by specialists. Ask your vet which technique they perform and their annual case volume.
How long can I wait before deciding on surgery for a CCL rupture?
Delay without stabilization allows progressive joint damage and meniscal injury. Most orthopedic surgeons recommend surgical evaluation within 2 to 4 weeks of diagnosis. Very prolonged delay (months) makes surgery more complex and recovery longer.
Is conservative management ever appropriate for CCL rupture?
In dogs under 10 kg, strict rest and rehabilitation has a reasonable success rate. In medium and large dogs, non-surgical management typically causes chronic instability and progressive osteoarthritis. Most specialists recommend surgery for medium and large breeds.
What does a specialist referral for orthopedic surgery actually involve?
The specialist performs a consultation examination, reviews imaging, discusses surgical options and recovery expectations, provides a written estimate, and schedules surgery. Your general vet receives a discharge summary and manages follow-up. See the full referral process guide for details.
My dog has both hips affected. Should both be done at the same time?
Generally no. Bilateral procedures are staged to allow one limb to recover before operating on the other. The interval is typically 8 to 12 weeks. Discuss staging with the specialist at the consultation.
How do I prepare my dog for an orthopedic specialist consultation?
Bring all prior radiographs, recent bloodwork, the full medication list, and records from prior treatments. A written summary of when lameness began and how it has progressed helps the specialist assess the timeline efficiently.

Recognize and Manage Post-Surgical Complications in Referred Patients
When a dog is discharged from a specialist after orthopedic or complex soft tissue surgery, the referring veterinarian and the owner become the first line of detection for complications. Surgeons rely on accurate observation and timely reporting from both.
Most complications after referral surgery are manageable when caught early. Missing them until they escalate is what turns a treatable problem into a crisis.
Quick answer: Common complications after referral surgery include surgical site infection, seroma, wound dehiscence, persistent pain, and behavioral changes. Implant failure, deep infection, and non-healing wounds require re-referral. Contact the surgical team promptly for anything beyond local wound care.
Key takeaways
- Referring vets are often the first to see post-surgical complications during follow-up visits and owner calls
- The discharge summary must be read in full: medication errors and missed complications often stem from incomplete review
- Suture removal rechecks begin at 10 to 14 days; orthopedic cases need imaging at 6 to 8 weeks
- Implant failure, deep infection, and non-healing wounds require re-referral rather than local management alone
- Behavioral changes (hiding, aggression, vocalizing) often signal pain before visible complications appear
- Clear documentation at every follow-up allows both the referring vet and specialist to track the case accurately
The referring vet's role after specialist discharge
SustainableVet: "The role of a referring veterinarian doesn't end when the surgery is done. The period after surgery is one of the most important times for the patient's recovery, and smooth communication between the surgical team and the referring vet is crucial."
After the specialist discharges the patient, the referring vet typically manages suture removal, post-surgical recheck examinations, medication management, client communication, and first-line detection of complications.
SustainableVet: "After the specialist performs the procedure, the referring veterinarian often monitors the patient's healing, manages medications, and supports the client with follow-up care. Without clear updates and guidance, this handoff can lead to confusion, missed issues, or delayed treatment."
Reading the discharge summary
The most preventable cause of post-referral complications is incomplete review of the discharge summary.
SustainableVet: "Skimming or missing parts of the summary can lead to medication errors, delayed care, or overlooked signs of complications. Examine the list of prescribed medications closely, noting the dosage and duration. Pay attention to any notes about potential complications the surgeon is concerned about."
What to extract from every discharge summary:
- Full medication list (drug, dose, frequency, duration)
- Recheck timeline (suture removal, imaging dates)
- Complications the surgeon flagged as possible for this specific case
- Activity restrictions and when they can be modified
- Criteria for contacting the surgical team directly
SustainableVet: "If anything in the notes is unclear, contact the surgeon before the pet's follow-up visit. It's better to clarify early than to risk confusion later."
Follow-up visit schedule
SustainableVet: "Follow-up visits usually begin 10 to 14 days after surgery for incision checks and suture removal. More complex cases, like orthopedic surgeries, may need additional visits at 6 to 8 weeks for imaging and rehab adjustments."
Soft tissue cases: day 10 to 14 for incision recheck and suture removal; further rechecks as indicated.
Orthopedic cases: day 10 to 14 for incision and medication review; week 6 to 8 for radiographs assessing bone healing and implant position; week 12 to 16 for complex cases.
SustainableVet: "During each visit, examine the incision site, check for swelling or pain, review mobility, and ensure the pet is healing as expected."
Common complications after referral surgery
Surgical site infection
SustainableVet: "Common issues include infection, swelling, bruising, wound reopening, fluid buildup, or implant-related problems in orthopedic cases."
Signs: increasing redness after day 3, yellow or green discharge, warmth, swelling not improving after day 5, foul odor, pain worsening rather than improving.
Local management: culture-guided antibiotics and wound care for shallow infections. PetPlace: "Wound infection that extends deeper into the tissues often requires surgery in addition to the antibiotic."
Re-refer for: deep infection not responding to antibiotics within 48 to 72 hours, infection near or involving an implant, implant exposure.
Seroma and hematoma
Soft fluctuant swelling beneath the incision. SustainableVet: "A seroma is usually soft, fluctuating, and not particularly hot or painful. Infection tends to produce heat, redness, and a firmer or more diffuse swelling, often with discharge."
Small seromas often resolve with strict rest. Larger seromas may need drainage. FNA confirms the nature of the fluid if clinical assessment is inconclusive.
Wound dehiscence
SustainableVet: "Wound dehiscence means the incision has come open, either partially or fully. It can happen when sutures break down, when infection weakens the tissue, when the dog is too active, or when licking has damaged the closure."
Partial dehiscence requires same-day attention. Full dehiscence with tissue exposure is a surgical emergency. Cover with a clean, damp cloth and go to the vet immediately.
Re-refer for: dehiscence of a complex closure after orthopedic or abdominal surgery.
Persistent pain or lameness
SustainableVet: "Persistent pain or lameness: ongoing discomfort beyond the expected recovery period can signal internal complications or implant issues."
In orthopedic cases, lameness persisting beyond the expected timeline may indicate implant loosening, bone healing delay, or periimplant infection. Radiograph before making treatment decisions.
Behavioral changes
SustainableVet: "Behavioral changes: hiding, aggression, vocalizing, or reluctance to move may reflect pain or anxiety." These often precede visible complications. Do not dismiss behavioral regression in a previously progressing patient.
When to contact the surgical team
SustainableVet: "If there are signs of implant failure, deep infection, or non-healing wounds, the case should be sent back to the surgeon. Immediate communication helps avoid delays in treatment and supports better outcomes."
Contact the surgical team for: any complication involving an orthopedic implant, deep infection not responding to first-line treatment, wound dehiscence of a complex closure, lameness or pain worsening at expected improvement timepoints, or any complication beyond local wound care capacity.
SustainableVet: "Timely referral prevents delays in advanced care and keeps outcomes favorable."
For the owner-facing complications guide, see signs of complications after soft tissue surgery. For the wound care protocol to review with clients, see wound care after surgery. For the full recovery care overview, see soft tissue surgery care for dogs.
Frequently asked questions
Should I treat complications locally or call the surgeon first?
For surface wound issues (minor infection, small seroma), local management with documentation is appropriate. For implant involvement, deep infection, or dehiscence of complex closures, contact the surgical team before acting.
What should I tell owners at the referral recheck appointment?
Review discharge instructions. Confirm medication compliance, E-collar use, and activity restriction. Assess and photograph the wound. Set clear expectations for the next recheck and which signs require an earlier call.
How do I distinguish a seroma from an infected pocket?
SustainableVet: "A seroma is soft, fluctuating, and not hot or painful. Infection produces heat, redness, and firmer swelling, often with discharge." FNA confirms the difference when clinical assessment is inconclusive.
The owner says the dog is fine but the incision looks concerning. Who is right?
Trust the physical examination over owner assessment. Owners naturally minimize signs. Document your findings, photograph the incision, and manage based on clinical evidence.
What imaging is needed at the 6-week orthopedic recheck?
Radiographs of the operative region in the same views as the post-operative images from the discharge summary. Compare implant position, bone healing, and periimplant margins against the surgical baseline.
How should I document follow-up findings for the surgical team?
Photograph the incision at every visit. Record date, appearance, discharge presence, pain score, and mobility assessment. If re-referral becomes necessary, this documentation allows the surgeon to assess progression without needing to reconstruct the timeline from memory.

Fracture Management in Dogs: When to Splint or Refer?
A broken bone in a dog needs one of three things: rest and confinement, external coaptation (splint or cast), or surgical repair. The decision depends on the bone affected, the fracture pattern, the dog's size and age, and the available equipment.
Getting this decision right the first time matters. Fusion Veterinary Orthopedics: "Attempting to use a splint or cast for several weeks with the hope of the fracture healing and doing surgery later is not advised. Chronic non-healing fractures are far more difficult to realign, are more costly, and have a lower likelihood of healing."
Quick answer: External coaptation suits minimally displaced fractures below the elbow or stifle in large adult dogs. Comminuted, articular, open, and upper-limb fractures require surgery. Small and toy breed distal radius fractures almost always need surgical repair.
Key takeaways
- Splints only work for fractures below the elbow or stifle: humeral and femoral fractures cannot be adequately immobilized externally
- Comminuted and articular fractures always require surgery: they are too unstable for external coaptation to maintain alignment
- Open fractures require emergency treatment within 8 hours: irrigation, debridement, and temporary stabilization precede definitive fixation
- 83% of distal radius/ulna fractures in small and toy breeds managed with external coaptation result in malalignment or nonunion
- Growth plate fractures should be surgically repaired within 24 to 48 hours of injury to minimize long-term joint damage
- Consult a board-certified surgeon for complex fractures including spinal, articular, and small-breed distal radial/ulnar
The three management options
1. Cage rest alone: reserved for very young dogs (puppies) with minimally displaced, inherently stable fractures for example, some rib fractures and stable pelvic fractures where the dog's own muscle mass provides sufficient immobilization.
2. External coaptation (splint or cast): for fractures below the elbow or stifle, minimally displaced, in stable large-breed adult dogs. Today's Veterinary Practice: "Ideal fractures for primary fixation using external coaptation include incomplete diaphyseal tibial fractures in young dogs, sometimes referred to as 'greenstick fractures.'"
3. Surgical repair: for the majority of fractures in adult dogs, all fractures in small and toy breeds, all comminuted and articular fractures, all open fractures, and all fractures above the elbow or stifle.
When external coaptation is appropriate
External coaptation requires that the joints above and below the fracture can both be immobilized. This is only achievable for fractures distal to (below) the elbow and stifle.
Clinical Brief: "External coaptation may be successful in fractures below the elbow or stifle, where the joints above and below the fracture can be fully immobilized."
Fractures that may be managed with splinting:
- Greenstick (incomplete) tibial fractures in young large-breed dogs
- Minimally displaced distal radius fractures in large-breed adult dogs
- Some metacarpal and metatarsal fractures
- Toe fractures
How splints are applied: Today's Veterinary Practice: "The splint should span the joint above and below the fracture, and be padded enough to prevent pressure sores and prevent movement of the limb." After placement, a radiograph confirms alignment.
Complications of splinting: ACVS: "Bandages and splints can cause very serious complications. They can be an effective treatment tool for fracture healing and pain control, but careful monitoring and appropriate follow-up must occur." Pressure sores, bandage slippage, and limb swelling are the most common complications; daily monitoring is essential.
When surgical repair is required
Fractures above the elbow or stifle
Animal Medical Center: "It is easy to temporarily immobilize bones below the elbow and knee, while the upper arm and thigh are more challenging to manage because the shoulder and hip are difficult to splint."
Today's Veterinary Practice: "Temporary stabilization of humeral and femoral fractures should not be attempted. In these cases, hospitalization with confinement to a crate along with analgesic relief is ideal while awaiting definitive fixation."
SustainableVet: "Trying to splint these upper limb fractures often leads to pain, delayed healing, and poor limb function. Immediate referral for surgical repair is recommended."
Comminuted fractures
A comminuted fracture means the bone is broken into multiple pieces. These are mechanically unstable fragments shift with any weight bearing. SustainableVet: "These are very unstable and cannot be held in place by a splint alone. The pieces move easily, and the risk of poor healing is high. In these cases, surgical fixation is needed to realign and stabilize the fragments."
Articular fractures (fractures entering a joint)
Any fracture that enters a joint surface requires anatomical reduction the fracture fragments must be restored to near-perfect anatomical position and rigid fixation to prevent joint surface step-off and subsequent arthritis. Fusion Veterinary Orthopedics: "Any growth plate fracture or joint fracture should be treated as quickly as possible within about 24 to 48 hours after injury."
Open (compound) fractures
Animal Medical Center: "Open fractures often require an initial surgery to clean the wound and bone within 8 hours of the injury." The management sequence is:
- Immediate wound irrigation and debridement under anesthesia
- Temporary stabilization (bandage)
- Systemic antibiotics
- Definitive fracture repair after soft tissue stabilization
Do not attempt definitive fixation of a contaminated open fracture at the initial presentation; this dramatically increases infection risk.
Small and toy breed radius and ulna fractures
Today's Veterinary Practice: "In small and toy breed dogs, 83% of distal radius and ulna fractures addressed with external coaptation alone result in malalignment or nonunion. Therefore, internal fixation is recommended for these fractures in small and toy breed dogs."
SustainableVet: "Toy breeds like Chihuahuas, Pomeranians, and Yorkies are at high risk of nonunion. Their small bones have less blood supply, which slows healing. Even simple fractures may not heal with splints alone."
Spinal fractures and luxations
Spinal fractures with cord involvement are neurosurgical emergencies requiring immediate specialist referral for stabilization and decompression. Clinical Brief: "For complex fractures including spinal, consider consultation with a boarded veterinary surgeon or referral to a specialty practice."
Surgical options for fracture repair
Vets4Pets provides a useful overview: "Two types of surgical fracture repair are normally used in pets. Internal fixation involves placing surgical screws, pins, or metal plates under the skin around the fracture site to stabilize the bone. External fixation involves attaching surgical scaffolding to the bone through small holes in the skin."
Specific implant systems used:
- Intramedullary (IM) pins: inserted down the bone canal; suitable for some long-bone fractures
- Bone plates and screws: the most common implant system; provides rigid fixation; locking plate systems are particularly stable
- External skeletal fixators (ESF): transcutaneous pins connected by an external frame; useful for open fractures, infected fractures, and certain metaphyseal fractures
- Interlocking nails: for femoral and tibial shaft fractures
Timing matters
Animal Medical Center: "You should treat a closed fracture within 2 to 4 days. Timely veterinary fracture repair can prevent complications like bone misalignment or long-term mobility issues."
Fusion Veterinary Orthopedics: "Chronic non-healing fractures are far more difficult to realign, are more costly, and have a lower likelihood of healing."
Delaying evaluation hoping the dog will be "better tomorrow" consistently leads to worse outcomes. Fractures should be radiographed and assessed by a veterinarian on the day they are suspected.

Frequently asked questions
My dog is walking on the leg a little. Does that mean it is not broken?
No. Weight bearing on a fractured limb is common many dogs do not display obvious non-weight-bearing lameness with incomplete or minimally displaced fractures. Any dog with pain, swelling, or abnormal limb conformation after trauma needs radiographs.
How do I transport a dog with a suspected broken leg to the vet?
Keep the dog calm and restrict movement. Do not splint at home; improper application can worsen the fracture. Carry small dogs; use a rigid surface for large dogs. Call ahead so the clinic can prepare.
Will my dog's fracture heal faster with rest than surgery?
For fractures that require surgery, no. Fusion Veterinary Orthopedics: "Surgery ensures optimal alignment and stabilization for less pain and faster healing." Splinting a fracture that needs surgery delays appropriate treatment and often results in malunion or nonunion.
What is a growth plate fracture and why is it urgent?
Growth plates are bone formation zones at long bone ends in immature dogs. Fractures disrupt blood supply to growth cells. Fusion Veterinary Orthopedics: "Growth plate fractures should be treated within 24 to 48 hours." Delay risks permanent deformity.
Can a dog live with an untreated fracture?
Some dogs survive without repair, particularly with stable pelvic fractures. However, untreated fractures often result in malunion, nonunion, chronic pain, and permanent functional loss. Any decision against surgery should be fully informed.
How often does a splint need to be checked when my dog is wearing one?
ACVS: splints require careful monitoring and appropriate follow-up. Checks every 3 to 5 days are standard initially. Watch for swelling above or below the splint, foul odor, cold or pale toes, or the dog chewing the bandage.

Hip Dysplasia Management: When Is Surgery the Best Option?
Hip dysplasia is one of the most common orthopedic diagnoses in dogs, but it doesn't always mean surgery is coming.
Many dogs with hip dysplasia live comfortably for years on conservative management. Others reach a point where pain or mobility loss makes surgery the right path. Knowing which situation your dog is in, and which surgical option makes sense, is what this guide is for.
Quick answer: Surgery becomes the best option for hip dysplasia when conservative management no longer controls pain, when mobility is significantly impaired, or when a dog is young enough for preventive procedures. The two main surgical options are FHO (femoral head ostectomy) and THR (total hip replacement), each suited to different dogs.
Key takeaways
- Surgery isn't always necessary: many dogs manage well with medication, weight control, and physiotherapy.
- Two main surgical paths exist: FHO removes the femoral head; THR replaces the entire joint.
- FHO suits smaller dogs and tight budgets; THR delivers better function in large, active breeds.
- Early preventive surgery (DPO/TPO) is an option for puppies under 10 months with minimal joint damage.
- The trigger for surgery is quality of life, not the X-ray grade alone.
- Delaying surgery in severe cases worsens outcomes: arthritis accumulates and options narrow.
What hip dysplasia actually is
Hip dysplasia is a developmental condition in which the ball (femoral head) and socket (acetabulum) of the hip joint don't fit together correctly. Instead of a tight, smooth connection, the joint is loose, allowing abnormal movement that gradually wears down cartilage and produces bone-on-bone friction.
The result is pain, inflammation, and over time, progressive osteoarthritis.
Hip dysplasia is most common in large and giant breeds: German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers, and Saint Bernards among the most frequently affected, but it occurs in any size dog.
The severity on X-ray does not always match the dog's visible symptoms. Some dogs with significant radiographic changes are relatively comfortable. Others with moderate findings are clearly in pain. Both the X-ray and the clinical picture matter.
When conservative management is enough
For many dogs with hip dysplasia, especially mild to moderate cases, non-surgical management controls symptoms well enough that quality of life is maintained without surgery.
Conservative management typically includes:
- Weight management: Reducing body weight is the single most impactful intervention. Every pound of excess weight adds direct mechanical load to an already unstable joint.
- Pain medication: NSAIDs (such as carprofen, meloxicam, or grapiprant) reduce inflammation and pain. Regular bloodwork monitoring is required for long-term NSAID use.
- Joint supplements: Glucosamine, chondroitin, and omega-3 fatty acids support cartilage health and reduce inflammation over time.
- Physical therapy and low-impact exercise: Controlled walking, swimming, and hydrotherapy build the muscle mass that stabilizes the joint and reduces the load on the hip.
- Environmental modifications: Ramps instead of stairs, non-slip flooring, orthopedic bedding.
Conservative management doesn't fix the underlying anatomy. It manages symptoms within the constraints of what the joint can do. When symptoms outgrow what this approach can control, surgery enters the conversation.
For non-surgical alternatives in more detail, see non-surgical alternatives to consider.
When surgery becomes the better path
According to Ask A Vet (2025), surgery is recommended when conservative management fails or when early intervention can prevent arthritis. The clinical signals include:
- Persistent limping or bunny-hopping that doesn't resolve with medication and rest
- Reluctance to stand, jump, or climb stairs that's significantly limiting daily life
- Muscle atrophy in the hindquarters from disuse
- Radiographic evidence of progressive joint damage alongside clinical decline
- Quality of life that is clearly impacted despite consistent conservative management
The decision to move to surgery is a quality-of-life decision, not purely a radiographic one. Two dogs with similar X-rays may need different approaches based on their clinical response to conservative care.
The surgical options for hip dysplasia
FHO (femoral head ostectomy)
FHO removes the head and neck of the femur: the "ball" of the ball-and-socket joint. The remaining femur is cushioned by a "false joint" of fibrous scar tissue that forms over the following weeks.
Best suited to:
- Small to medium dogs (typically under 50 lbs)
- Any size dog when THR isn't feasible (financial constraints, health contraindications)
- Cats
Limitations: The false joint doesn't provide the mechanical function of a real hip. Large breeds may have residual pain or gait abnormality. Function depends heavily on muscle mass and rehabilitation.
For a full explanation of what the procedure involves, see what FHO surgery is and how it helps.
THR (total hip replacement)
THR replaces the entire hip joint with a prosthetic implant. The femoral head and acetabulum are both replaced with precisely fitted components.
Best suited to:
- Medium to large dogs (typically over 40 to 50 lbs) who want full athletic function restored
- Skeletally mature dogs (typically over 9 to 12 months)
- Dogs in otherwise good health without significant comorbidities
Advantage over FHO: THR restores near-normal hip anatomy and function. Success rates of 80 to 98% are reported across published studies. Large active breeds return to full exercise capacity more reliably than with FHO.
For a full overview of the THR procedure, see total hip replacement as an alternative.
DPO/TPO (double or triple pelvic osteotomy)
This is a preventive surgery performed only in young dogs (typically under 10 months old) with hip laxity but minimal joint damage. The surgeon cuts and rotates the pelvic bones to improve how the socket holds the femoral head, reducing abnormal motion before cartilage damage accumulates.
Candidates: puppies with confirmed hip laxity on radiograph, little or no arthritis, and growing bones.
This window closes as the dog matures and joint damage develops.
How to know which surgical option applies to your dog
The right surgical option depends on the intersection of several variables:
| Factor | Points toward FHO | Points toward THR |
|---|---|---|
| Body weight | Under 45 to 50 lbs | Over 45 to 50 lbs |
| Activity level | Moderate | High / working dog |
| Budget | More affordable | Significantly higher cost |
| Age | Any age | Skeletally mature |
| Expected function | Pain-free comfortable movement | Full athletic restoration |
| Health status | FHO is lower-risk surgery | THR requires good systemic health |
For the direct comparison of FHO versus THR across all major factors, see FHO vs total hip replacement for hip dysplasia.
For the specific indications that guide the FHO recommendation, see when FHO is recommended.
The cost of waiting
For dogs with mild disease and adequate pain control, watchful waiting is entirely appropriate.
For dogs with moderate to severe disease where quality of life is declining, delay carries real costs:
- Progressive arthritis: The damaged joint continues to deteriorate. Every month of delay means more cartilage loss and more established arthritis.
- Muscle atrophy: Disuse of the painful leg causes the supporting muscle to waste away, making recovery from eventual surgery harder and longer.
- Narrowing options: As joint damage progresses, some surgical options become less appropriate. DPO/TPO is only available during a brief window in puppyhood.
Early action, when indicated, typically means simpler surgery, cleaner recovery, and better long-term outcomes.
For guidance on whether your dog is a candidate for THR specifically, see how to know if your dog is a THR candidate.
Frequently asked questions
My dog has hip dysplasia but doesn't seem to be in pain. Do they need surgery?
Not necessarily. Many dogs with hip dysplasia compensate well and show minimal pain, particularly in early disease. Conservative management, weight control, and monitoring are appropriate first steps. Surgery is indicated when pain is not controlled or mobility is meaningfully impaired, not simply because the diagnosis exists.
How old does a dog need to be for hip replacement surgery?
THR requires skeletal maturity, typically achieved at 9 to 12 months in most breeds and later in giant breeds. FHO can be performed at any age. DPO/TPO is only appropriate before 10 months of age in puppies with hip laxity and minimal arthritis.
Can hip dysplasia go away without surgery?
The underlying anatomic abnormality doesn't resolve. But many dogs with hip dysplasia maintain a good quality of life on conservative management for years, particularly those who remain lean and receive appropriate physiotherapy. "Going away" isn't the goal; managing symptoms within the joint's limits is.
Hip dysplasia doesn't come with a single right answer. The best path depends on your dog's size, age, severity of symptoms, response to conservative care, and your goals for their function and quality of life. The conversation with your vet and the X-ray findings together tell you more than either alone. Start early, monitor consistently, and make the surgical decision based on how your dog is actually living rather than the diagnosis on paper.

Joint Replacement Surgery in Dogs: Success Rates and Expectations
Joint replacement surgery is the most advanced intervention in veterinary orthopaedics.
For dogs with severe, irreversible joint disease that has not responded to medical management, it can transform quality of life in a way no medication or rehabilitation can match.
Quick answer: Total hip replacement in dogs achieves 90 to 95% good-to-excellent outcomes. It is indicated for end-stage hip OA unresponsive to conservative management. Recovery requires 8 to 12 weeks of strict rest. Cost is $4,000 to $7,000 per joint.
Key takeaways
- THR achieves 90 to 95% good-to-excellent function in appropriately selected dogs; most need no further pain medication after recovery
- THR complication rate is 5 to 10%: post-operative luxation is most common, occurring in 3 to 5% of cases
- THR is indicated for end-stage hip dysplasia OA not responding to conservative management; it is a salvage procedure, not first-line
- Total elbow replacement is available at only a few specialist centres and has higher complication rates than THR
- Strict activity restriction for 8 to 12 weeks post-surgery is essential owner compliance is one of the most important factors in outcome
- Cost is $4,000 to $7,000 per joint at specialist centres; bilateral cases require two separate procedures
Total hip replacement (THR)
What it is
Total hip replacement removes the femoral head and acetabulum and replaces both with prosthetic implants a metal femoral stem with a ball, and a metal or polyethylene acetabular cup.
The new joint provides smooth, pain-free movement without the bone-on-bone contact of advanced hip OA.
Canine joint replacement technology and surgeon expertise have advanced greatly over the past 20 years. Only a few relatively small companies worldwide supply the technology for joint replacement surgery, and a relatively low number of surgeons have the expertise to consistently perform the procedure with a high degree of proficiency.
Success rates
The success rate for total hip replacement in dogs is very high between 90% and 98%. Most dogs experience significant pain relief, improved movement, and a better quality of life.
Studies show more than 90 to 95% of dogs have good to excellent function with THR, providing years of pain-free activity that otherwise would not have been possible.
A large registry study reviewed 2,375 THRs in 1,852 dogs over 10 years. The majority of cases were hip dysplasia with osteoarthritis.
Owner-reported outcomes were strongly positive in the vast majority of cases.
Complications
The typical overall complication rate following a THR varies, with a reported overall average complication rate of 5 to 10%. The more commonly reported complications include postoperative luxation, often associated with a fall or excessive activity.
The most frequent complication is hip dislocation, occurring in approximately 3 to 5% of cases. Other potential complications include fracture, nerve injury, or infection.
Most complications are managed without losing the implant. Catastrophic failure requiring implant removal is uncommon in experienced hands.
Candidates for THR
Good candidates:
- Dogs with hip dysplasia and severe OA causing significant pain and reduced quality of life
- Dogs that have failed conservative management (weight management, NSAIDs, rehabilitation)
- Dogs with adequate bone stock to accept the implant
- Dogs whose owners can commit to strict post-operative restriction
Not candidates:
- Dogs with neurological disease affecting the same limb
- Dogs with active infection in or near the joint
- Dogs with severe muscle atrophy at time of surgery
- Dogs with other significant orthopaedic disease in the same limb
Candidates for THA must not have other orthopaedic disease in the limb to be operated, as well as clients willing to perform the postoperative care necessary for a successful outcome.
Implant systems
Two main systems exist: cemented (implant fixed with bone cement) and cementless (press-fit, relying on bone ingrowth for long-term fixation).
Cementless systems are now more widely used and have longer documented longevity in dogs.
In most cases, the replaced hip will last for your pet's lifetime.
Total elbow replacement
Total elbow replacement (TER) is significantly more complex than THR and available at only a small number of specialist centres worldwide.
Total elbow arthroplasty continues to be under development. The system is technically demanding and may be the reason it is not used more widely by veterinary surgeons.
The T.A.T.E. elbow system is the most widely used current system.
Indications include end-stage elbow OA from fragmented medial coronoid process disease or other elbow dysplasia conditions that have exhausted all other options.
Complication rates for total elbow replacement are higher than THR.
It is a salvage procedure reserved for dogs that have failed all other surgical and medical options and where FHO-equivalent (head and neck excision) is not anatomically applicable.
Cost
The cost of a total hip replacement typically ranges from $4,000 to $7,000. Elbow and knee replacements may fall within a similar or slightly higher range due to complexity. Although the upfront cost is high, joint replacement can eliminate the need for ongoing pain medications, frequent vet visits, or repeated surgeries.
Bilateral THR (both hips) nearly doubles the cost. Most surgeons stage bilateral cases 8 to 16 weeks apart rather than performing both simultaneously.
Recovery
Activity restrictions are significant during the initial 8 to 12 weeks of recovery. Your pet should not be allowed to be off leash, run, or jump. Your pet should be strictly confined to a small indoor area with non-slippery floors or in a crate. Most pets are ready to resume regular exercise and activities after 12 weeks of recovery.
Recovery milestones:
- Days 1 to 14: crate rest, leash-only bathroom walks, pain medication
- Weeks 2 to 8: progressive short leash walks, rehabilitation exercises begin
- Weeks 8 to 12: radiographic recheck, gradual activity increase if healing is confirmed
- Month 3 to 6: peak recovery; most dogs reach full or near-full function
Rapid recovery and high performance are expected not just hoped for in current veterinary orthopaedic surgery.
For the full rehabilitation guide covering the post-joint-replacement recovery period, see physical therapy and rehabilitation: how referring vets can support recovery.
For the pain management approach used alongside joint replacement recovery, see orthopedic pain management in pets: multimodal approaches. For the referral decision, see when to refer for orthopedic surgery.
Frequently asked questions
Is my dog a candidate for total hip replacement?
The key criteria are: end-stage hip OA with significant pain and failure of conservative management.
Additionally: no neurological disease or orthopaedic disease in the same limb, adequate bone stock, and an owner able to comply with strict activity restriction.
A board-certified orthopaedic surgeon will assess suitability at a specialist consultation.
How long does a dog live after hip replacement?
The implant is designed to last the dog's lifetime. Most dogs require no further pain medication after recovery and return to near-normal activity.
The procedure does not shorten lifespan and typically significantly improves quality of remaining life.
What happens if the hip dislocates after surgery?
Post-operative luxation occurs in approximately 3 to 5% of cases, usually associated with excessive activity or a fall.
It is managed by manual reduction under anesthesia, followed by a period of restricted activity. In some cases, revision surgery is needed.
This is why strict activity restriction in the first 8 weeks is critical.
Is hip replacement better than FHO (femoral head ostectomy)?
For medium and large breeds, THR generally produces superior outcomes compared to FHO better gait, less muscle atrophy, and more reliable function.
FHO is a reasonable salvage option for small and toy breeds where functional outcomes are more reliable, or when the cost of THR is prohibitive.
Can both hips be replaced at the same time?
Rarely. Most surgeons stage bilateral THR 8 to 16 weeks apart to allow recovery of one limb before stressing the other.
Operating both simultaneously significantly increases anesthetic time and complication risk, and leaves the dog with no sound limb during recovery.

Post-Surgical Follow-Up: What Referring Veterinarians Need to Know
The surgeon closes the incision and hands the patient back. From that point, the referring vet carries the case.
Post-surgical care is not passive.
It requires active communication with the surgical team, structured recheck examinations, prompt complication recognition, and consistent owner support throughout a recovery that may last months.
Quick answer: Post-surgical follow-up for referred orthopedic patients includes reading the discharge summary before the first recheck, establishing a recheck schedule (suture removal at day 10 to 14, radiographs at week 6 to 8), recognizing complications early, and reinforcing owner compliance at every visit.
Key takeaways
- Read the discharge summary before the first recheck: skimming leads to medication errors, missed complications, and inconsistent owner instructions
- Standard orthopedic recheck schedule: suture removal at day 10 to 14; radiographs at week 6 to 8; final check at week 12 to 16
- Contact the surgical team for: implant complications, deep infection not resolving in 72 hours, wound dehiscence, or worsening lameness
- Owner compliance is the most modifiable variable: reinforce activity restrictions, E-collar use, and complication signs at every contact
- Refer back for: deep infection, implant-related concerns, wound dehiscence, or persistent non-weight-bearing beyond expected timepoints
- Document each visit clearly: both the referring vet and the surgical team need an accurate record to track patient progress
Reading the discharge summary
The role of a referring veterinarian does not end when the surgery is done. After the specialist performs the procedure, the referring veterinarian often monitors the patient's healing, manages medications, and supports the client with follow-up care. Without clear updates and guidance, this handoff can lead to confusion, missed issues, or delayed treatment.
The discharge summary is the primary communication from the surgical team.
It contains the diagnosis, the specific procedure performed, implant details, the prescribed medication list, the recheck schedule, and the complications to monitor.
Even when the specialist provides detailed discharge instructions, referring veterinarians often need to reinforce or adjust them during follow-up visits. Clients may forget or misunderstand what they were told at the surgical centre, especially if they were stressed or overwhelmed on discharge day.
What to extract from every discharge summary:
- Full medication list (drug, dose, frequency, duration)
- Recheck schedule and what assessment is required at each visit
- Specific complications the surgeon flagged for this case
- Activity restriction level and when it can be modified
- Criteria for contacting the surgical team directly
If anything is unclear, contact the specialist before the first recheck not after.
Recheck schedule
Soft tissue cases
- Day 10 to 14: incision assessment, suture removal, medication review
- Further rechecks: based on clinical signs and case complexity
Orthopedic cases
- Day 10 to 14: incision assessment, suture removal, gait assessment
- Week 6 to 8: radiographs to confirm bone healing and implant position
- Week 12 to 16: final assessment in complex cases; progressive activity increase if healing confirmed
If pain medications are still needed after a few weeks, it is best to follow up with your referring veterinarian.
Consistent scheduling helps track progress and catch complications early. Document each visit so both you and the specialist can follow the case.
What to assess at each recheck
At every visit:
- Incision appearance: closure status, discharge type and volume, redness, swelling
- Weight-bearing status on the affected limb
- Pain assessment using a standardized scale
- Muscle mass: compare bilaterally
- E-collar compliance
- Medication compliance and any adverse effects reported by the owner
At orthopedic rechecks:
- Joint stability (where applicable)
- Range of motion of the operated joint
- Radiographs at intervals specified in the discharge summary
Recognizing and triaging complications
Surgical site infection (SSI)
Signs: redness extending beyond the incision margins after day 3, purulent discharge, local heat, wound odor, systemic signs (fever, lethargy).
Management: culture and sensitivity before starting antibiotics. Surface infections can be managed locally. Deep infections, infections near implants, and infections not improving in 48 to 72 hours require surgical team contact.
Seroma
Soft, fluctuant non-painful swelling beneath the incision. Common after soft tissue and orthopedic surgery. Small seromas often resolve with strict rest. Larger seromas may need drainage under guidance from the surgical team.
Wound dehiscence
Partial or complete opening of the incision. Requires same-day assessment. Full dehiscence with tissue exposure is an emergency. Contact the surgical team before attempting local re-closure of complex wounds.
Persistent or worsening lameness
In orthopedic cases, persistent non-weight-bearing or worsening lameness beyond the expected timeline warrants radiographs and surgical team contact. Implant loosening, infection, or fracture propagation must be ruled out before managing locally.
Communicating with the surgical team
Smooth communication between the surgical team and the referring vet is crucial.
Contact the surgical team for:
- Any implant-related concern identified on radiograph
- Deep SSI not resolving with antibiotics in 48 to 72 hours
- Wound dehiscence of a complex closure
- Lameness or pain worsening rather than improving at expected timepoints
- Uncertainty about whether a finding requires re-referral
The GP's office should contact the orthopedic surgeon to get the discharge instructions, which include pin care and a schedule for pin removal. Call the specialty hospital on the day of surgery to get a briefing on the outcome and expected aftercare.
A proactive call immediately after surgery, confirming surgical findings and aftercare requirements, prevents the most common breakdown: managing a complication beyond scope while the problem worsens.
Supporting owners through recovery
Focus on key points like medication schedules, activity restrictions, wound care, and signs that need urgent attention. Avoid medical jargon clients appreciate straightforward, step-by-step guidance. You can provide these as printed handouts or digital summaries sent by email or text.
Follow-up communication needs to happen the day after the patient is discharged. Make sure you have updated contact information and the desired contact method. Encourage clients to call if they have any concerns once the pet is home.
Owner compliance particularly with activity restriction and E-collar use is the most controllable variable in post-surgical outcome. Non-compliance is the most common cause of wound complications and implant failure.
Reinforce it at every visit, not just at the first one.
For the complications guide covering specific scenarios and when to re-refer, see post-op home care for pets after orthopedic surgery.
For the communication framework between GP and specialist, see how to optimize communication between general practitioners and orthopedic surgeons.
Frequently asked questions
When should I contact the surgical team vs. manage locally?
Manage locally: minor incision redness not progressing, small seromas under active rest restrictions, mild expected lameness on the expected timeline.
Contact the surgical team: any implant concern, deep infection, wound dehiscence of a complex closure, worsening rather than improving lameness, or any complication you are unsure how to manage.
What imaging is needed at the 6-week orthopedic recheck?
Radiographs of the operated region in the same views as the post-operative images from the discharge summary. Compare implant position, bone healing, and periimplant margins.
If the surgeon provided post-operative radiographs in the discharge summary, use these as the baseline for comparison.
My client says the dog is doing great but the incision looks concerning. Who is right?
Trust the physical examination over owner assessment. Owners naturally minimise signs when they want their pet to be well.
Document your findings, photograph the incision, and manage based on clinical evidence rather than owner report.
How do I handle the case if I cannot reach the surgical team?
Document the attempt and the clinical finding. For non-emergency complications, continue conservative local management while attempting to reach the team.
For emergencies (wound dehiscence with tissue exposure, signs of systemic sepsis), act appropriately and continue attempting specialist contact. Never delay emergency care while awaiting specialist guidance.
How long does the referring vet typically follow the case?
For straightforward soft tissue cases, typically until the 10 to 14 day recheck and discharge.
For orthopedic cases, the referring vet typically follows the patient through the 6 to 8 week radiographic recheck and the 12 to 16 week final assessment.
This represents a total follow-up period of 3 to 4 months.

Post-Op Home Care for Pets After Orthopedic Surgery
Learn how to care for your pet after orthopedic surgery. Tips on pain, activity, wound care, and safe recovery at home
Orthopedic surgery recovery is significantly longer and more demanding than soft tissue surgery recovery. The bone, implants, and remodeled joint need 8 to 12 weeks to reach adequate strength not 10 to 14 days. What happens at home during this period determines the outcome at least as much as what happened in the operating room.
This guide covers everything from the first hours after arriving home through the 8-week imaging recheck.
Quick answer: After orthopedic surgery, restrict activity for 8 to 12 weeks. Start 5-minute leash walks within 24 hours; increase gradually. The 8-week radiograph recheck confirms bone healing. No running, jumping, or stairs until specialist clearance.
Key takeaways
- Activity restriction for 8 to 12 weeks is non-negotiable; bone healing does not accelerate with optimism
- Short leash walks start within 24 hours of orthopedic surgery weight bearing is beneficial for bone healing
- Ice the surgical site for the first 3 to 5 days: 10 to 15 minutes, 2 to 3 times daily
- The 8-week radiograph recheck confirms bone healing; do not increase activity until imaging clears it
- TPLO has a 2 to 10% failure rate; most complications involve infection (8 to 17% of cases) or implant irritation
- Rehabilitation exercises including passive range of motion and graduated leash walking improve outcomes
Setting up the home recovery space
Orthopedic surgery patients need a confined, safe space before they arrive home.
Required:
- Crate or small room: prevents uncontrolled movement, jumping, and access to stairs
- Non-slip flooring: orthopedic surgical patients are at high risk of slipping and falling; rubber mats or yoga mats over hardwood or tile are essential
- Floor-level bedding: no couch or bed access; orthopedic bedding (memory foam or egg-crate foam) reduces pressure on the operated limb and other joints compensating for it
- Baby gates on stairs and doorways to furniture rooms
MedVet TPLO recovery guide: "Restricting activity is extremely important. This generally means confinement to a crate or small room, no jumping, no running, no stairs, no rough housing, and no playing with other dogs until recovery is well advanced."
PAW Vet Practice: "The ride home after surgery deserves more thought than it commonly receives. A large dog may need help getting into the car. Use a flat loading approach if possible. Lift with support under both the chest and hindquarters, or use a ramp."
The first 24 to 72 hours
Expect grogginess, disorientation, and significantly reduced appetite the first evening. Pain medication dispensed at discharge should be given on schedule.
Ice therapy: TPLO Info: "We advise using ice therapy directly to the incision site for the first 3 to 5 days following surgery. Icing helps to reduce inflammation and pain at surgery sites." Apply a cold pack wrapped in a thin cloth for 10 to 15 minutes, 2 to 3 times daily. Never apply ice directly to skin or the incision.
Leash walks: TPLO Info: "We recommend taking your pet for short 5-minute leash walks multiple times a day, beginning within 24 hours after surgery." This is counterintuitive for many owners, but weight bearing stimulates bone healing and maintains joint range of motion and muscle mass.
Sling support: Dogwood Veterinary Surgical Care: "A sling may be used for the first 2 to 4 weeks after orthopedic surgery until better mobility is achieved." This helps with hind-end control, slows movement, and prevents slipping particularly important on smooth floors.
Activity progression: week by week
Oakland Veterinary Referral Services: "You can anticipate that your dog will need rest and exercise restrictions for 8 to 12 weeks. This allows the incision and bone to heal and the knee function to return."
Weeks 1 to 2:
- Leash walks only; 5 minutes, 2 to 3 times daily
- No stairs, no running, no off-leash time
- Suture or staple removal recheck at day 10 to 14
- Incision checks daily (morning and evening)
Weeks 2 to 8:Dogwood Veterinary Surgical Care: "After 2 weeks (or after suture removal), gradually increase your pet's leash walks by 5 minutes each week. Do not increase walking to more than 30 minutes by week 8."
- Week 2: 10-minute walks
- Week 3: 15-minute walks
- Week 4 to 6: 20-minute walks, can begin gentle inclines/declines on leash
- Week 7 to 8: 25 to 30-minute walks as tolerated
All walks must be on leash. Dogwood: "This increase in activity should be supervised and on a leash until full function is achieved."
Week 8: radiograph recheckDogwood: "Pets with orthopedic implants and expected bone healing should have additional radiographs performed in 8 weeks from the initial surgery."
Oakland OVRS: "At 8 to 10 weeks post-operatively, your surgeon will do recheck X-rays to assess bone healing. Your dog will be able to gradually resume normal activities."
If bone healing is confirmed: controlled activity can be gradually increased. If healing is incomplete: restrictions continue and the next recheck is scheduled.
Rehabilitation exercises
TPLO Info: "Physical rehabilitation protocols benefit recovery following a TPLO. It is important to tailor a rehabilitation protocol to a specific patient, considering the pet's range of motion, strength, degree of healing, and ability to perform each exercise."
Passive range of motion (PROM): performed daily, typically from day 1 to 2 post-surgery.
Dogwood: "Please start at the toes and work up the leg performing bending and extending exercises at each joint. 10 to 15 repetitions can be performed per joint as tolerated by your pet. Please go slowly and minimize stress."
How to perform PROM:
- Position the dog lying on their side, operated limb upward
- Support the limb with both hands; one on the femur, one on the tibia
- Gently flex and extend the stifle through a comfortable range
- Do not force the joint if the dog shows pain or resistance
- 10 to 15 slow repetitions per session, 2 to 3 times daily
Leash walking: the most important rehabilitation exercise. TPLO Info: "Weight bearing is good for bone healing, maintaining range of motion in the joints of the affected limb, and maintaining muscle mass."
Water treadmill: Dogwood: "Your pet may also benefit from water treadmill therapy." Underwater treadmill allows supported weight bearing with reduced joint load excellent for pain-limited patients who need more exercise than on-land walking allows.
Oakland OVRS: "We recommend a rehabilitation program to optimize your dog's recovery. The rehabilitation facility should have experience in postoperative recovery from orthopedic injuries such as the TPLO."
At-home exercises from week 2 to 4 (if formal rehab is not available):
- Sit-to-stand exercises (5 to 10 repetitions): strengthens the quadriceps
- Slow leash walk on varied terrain: promotes proprioception
- Gentle inclines and declines on leash from week 4 onward
Incision care for orthopedic surgery patients
The incision care principles are the same as for soft tissue surgery with two additional considerations:
Implant-associated infection: infection around orthopedic implants (TPLO plate, fracture repair screws) is significantly more serious than soft tissue SSI. PAW Vet Practice cites SustainableVet's data: "TPLO has a low failure rate of 2 to 10%, and most complications relate to manageable issues such as infection, which occurs in 8 to 17% of cases, or implant irritation."
Any sign of infection near an orthopedic implant requires prompt veterinary assessment and specialist contact. Do not attempt to manage periimplant infection locally without specialist input.
E-collar compliance: orthopedic incisions are often on the limb a location dogs can reach. E-collar must be worn at all times.
Pain management
Orthopedic surgery creates more significant post-operative pain than most soft tissue procedures. Multi-modal pain management is standard:
- NSAIDs (meloxicam, carprofen, grapiprant): reduce inflammation and provide analgesia; give with food; do not skip doses
- Gabapentin: neuropathic pain component; expect additional sedation
- Tramadol or buprenorphine: for the immediate post-operative period in higher-pain patients
Signs that pain is not adequately controlled: panting at rest, inability to settle, not eating at day 2 or beyond, whimpering when the limb is touched. Call the vet for medication adjustment.
Warning signs that require a vet call
| Finding | Action |
|---|---|
| Sudden increase in lameness | Call vet same day |
| Non-weight bearing after day 3 | Call vet same day |
| Incision redness, discharge, or odor | Call vet same day |
| Soft swelling near the implant | Call vet within 24 hours |
| Dog cries when the limb is touched | Call vet same day |
| Limb is cold or pale | Emergency: go now |
| Pain not controlled by medication | Call vet same day |
Today's Veterinary Practice: "Clinical signs include acute onset of lameness, pain on palpation of the implant, and possible bony thickening or swelling more than 1 year after surgery. Radiographic examination is indicated for patients with these clinical signs."
For the full complications guide covering what these findings mean, see post-surgical complications in referred pets. For the infection-specific guide, see dog incision infection signs causes and treatment. For the general recovery care context, see soft tissue surgery care for dogs. For when referral was appropriate, see when to refer orthopedic cases.
Frequently asked questions
My dog is already using the leg well on day 5. Can I let them off the leash?
No. Early weight bearing is expected and positive but does not indicate bone healing. Bone consolidation takes 8 to 10 weeks minimum. Off-leash activity risks implant failure or joint instability regardless of how the dog appears.
How do I know if the bone is healing correctly?
Radiographs at the 8-week recheck are the only reliable way to assess bone healing. Clinical improvement (weight bearing, reduced lameness) correlates with but does not confirm bone healing. Do not substitute clinical assessment for imaging.
My dog is still very lame at week 4. Is that normal after TPLO?
Some degree of lameness at week 4 is common, especially in large dogs. Gradual, consistent improvement is the pattern to look for. Sudden worsening, complete non-weight bearing, or no improvement at all by week 4 warrants a veterinary assessment.
Can I start swimming during the recovery period?
Open-water swimming is not permitted during the restricted activity phase. Underwater treadmill in a clinical rehabilitation setting is different and may be recommended by your vet as a controlled form of rehabilitation. Ask your vet specifically.
What is a sling and do I need one?
A sling is a soft harness under the hindquarters that partially supports the dog's weight and guides movement. Dogwood: "This helps with hind-end control and prevents slipping." Not all patients need one; ask your surgeon.
My dog had a TPLO and the opposite leg now seems lame too. What does that mean?
Contralateral limb lameness is common after TPLO. The dog shifted weight to the unaffected leg during recovery, increasing its load. Underlying CCL disease affects both legs in many dogs. Have the new lameness assessed promptly.

What to Expect When Your Patient Sees an Orthopedic Specialist
Learn what to expect during a veterinary orthopedic referral—from diagnosis and imaging to treatment planning and follow-up care
Referral to a veterinary orthopedic specialist is a significant step for an owner.
Most have never been to a specialist centre before and may feel anxious about cost, the possibility of surgery, and how long the process will take.
Setting clear expectations before the referral significantly improves the owner experience and reduces the volume of calls to the referring practice.
Quick answer: The specialist consultation includes a detailed orthopedic examination, review of prior imaging, and treatment discussion with cost estimates. It takes 60 to 90 minutes. Surgery is scheduled separately after diagnosis is confirmed. Bring all prior radiographs, blood work, and a medication list.
Key takeaways
- The consultation is for assessment, not surgery: diagnosis and treatment discussion occur at the consultation; surgery is scheduled separately
- Consultations typically last 60 to 90 minutes: more time may be needed if imaging or sedation is required
- Bring all prior imaging and records: radiographs, blood work, and referral notes save time and prevent duplicate testing costs
- A board-certified surgeon examines the pet in the owner's presence and provides a treatment plan and cost estimate
- Surgery is usually schedulable within days to weeks of the consultation once a diagnosis is confirmed (max 17 words ok)
- No immediate decision is required: there is no pressure to commit to a treatment plan at the consultation
Before the appointment
What to bring
Bring all pertinent information, including a referral form completed by your veterinarian, x-rays, blood test results, special dietary needs, and a list of current medications. Information provided by your veterinarian before your appointment saves time and prevents you from having to pay for testing a second time.
Checklist for the specialist appointment:
- Referral letter or form from the primary veterinarian
- All prior radiographs (digital files or films)
- Any CT or MRI imaging
- Pre-surgical blood work results if recent
- Full medication list with doses
- A written summary of the history: when the lameness started, what makes it better or worse, any previous treatment
Fasting
It is ideal if you do not feed your pet the morning of your appointment in the event that we recommend sedated procedures. However, please do offer your pet water at all times.
Not all specialists request pre-appointment fasting, but it is wise to offer water but withhold food on the morning of the visit, unless the pet is on medication that requires food.
Confirm with the specialist centre when booking.
Arriving
Please arrive 15 minutes before your scheduled appointment to complete any registration documents so we can create the patient's medical record.
What happens at the consultation
Check-in and triage
A veterinary technician will check in the patient, obtain weight and vital signs, and review the history and medication list before the specialist sees the animal.
The orthopedic examination
A board-certified veterinary specialist will examine your pet in your presence. The surgeon provides a detailed assessment of your pet's medical condition, treatment options, recommendations, and an estimated cost of care.
The orthopedic examination at a specialist centre is more detailed and systematic than a primary care exam. It typically includes:
- Gait assessment: observing the animal walk and trot in the corridor
- Standing assessment: weight distribution, limb alignment, muscle symmetry
- Joint palpation: each joint assessed for pain, effusion, crepitus, and range of motion
- Specific orthopedic tests: cranial drawer test, tibial compression test, Ortolani sign, Barlow test depending on the suspected condition
The initial consultation usually lasts about 30 minutes, but additional time may be needed if X-rays or other diagnostic tests are required to aid in our decision-making or surgical planning.
Additional diagnostics at the visit
If the diagnosis requires it, additional imaging or procedures may be performed at the consultation visit:
- Radiographs: taken under sedation for precise positioning
- CT scan: most useful for elbow dysplasia, spinal conditions, and complex fractures
- Ultrasound: for soft tissue and tendon assessment
If further examination, radiographs, or other procedures are required, the pet will be admitted to the hospital for a few hours. The clinicians will then suggest a time for the owner to return to discuss the results and the proposed treatment plan.
Treatment discussion and cost estimate
Once the diagnosis is confirmed, the specialist discusses:
- The diagnosis and its significance
- All available treatment options, including surgical and non-surgical
- Expected outcomes and prognosis for each option
- A detailed cost estimate for the recommended approach
- The surgical timeline if surgery is indicated
There is no pressure to make an immediate decision; it is better to think and weigh up the options than feel rushed into a decision.
Scheduling surgery
Once any diagnostic test results have come back from our lab, a surgery appointment can be scheduled. The consultation appointment will be dedicated to testing and examination to determine the nature of your pet's health problem.
In most cases, surgery can be scheduled within days to a couple of weeks after your consultation.
Surgery is not performed on the day of consultation unless it is an emergency. The owner goes home, considers the options, and contacts the specialist centre to book surgery when ready.
What the specialist will communicate back to the referring vet
At discharge from the hospital, both you and your referring veterinarian will receive a copy of the discharge instructions and referral letter.
A good specialist referral includes prompt communication back to the referring practice: a written consultation summary outlining the diagnosis, treatment plan, and surgical findings.
This keeps the referring vet informed and supports continuity of care.
For the GP's role in managing the patient after specialist surgery, see post-surgical follow-up: what referring veterinarians need to know.
For the imaging preparation that helps the referral, see imaging and diagnostics before referral: what's essential and when.
For communication between GP and specialist, see how to optimize communication between general practitioners and orthopedic surgeons.
Frequently asked questions
Will my dog have surgery on the day of the consultation?
No, in almost all cases. The consultation is for assessment and diagnosis.
Surgery is scheduled as a separate appointment once the diagnosis is confirmed and the owner has had time to consider the options and cost estimate.
How long will the appointment take?
Consultations take approximately 60 to 90 minutes. Please carefully plan your schedule and time requirements.
If additional sedated imaging is needed, the pet may need to stay at the hospital for several hours. The owner is typically contacted when the pet is ready for collection.
Can I get a second opinion from a specialist?
Yes. Second opinion consultations are welcome at any stage. There is no obligation to proceed with treatment.
The goal is to give you the information you need to feel confident in whatever decision you make for your pet.
What if surgery is not the right option?
Not all orthopedic conditions require surgery. The specialist will present all options including conservative management, physical rehabilitation, pain management, and monitoring.
Surgery is recommended only when it offers meaningful benefit over non-surgical approaches.
My dog is old. Will the specialist still consider surgery?
Age alone is not a contraindication to orthopedic surgery. Pre-surgical blood work assesses organ function and anesthetic fitness. Many older dogs have successful orthopedic procedures.
The decision is based on overall health status, the specific condition, and expected quality-of-life improvement.

Surgical Antimicrobial Prophylaxis Guide for Vet Surgeons
Discover the best practices in surgical antimicrobial prophylaxis for veterinary surgeons—guidelines, antibiotic choices, timing, and infection prevention tips
Surgical antimicrobial prophylaxis (SAP) is the use of antibiotics before or during surgery to reduce the risk of surgical site infection. It is not treatment there is no infection to treat.
The goal is to achieve adequate drug concentrations in the tissues at the time bacteria first enter the wound.
Done correctly, SAP is an evidence-based infection control tool. Done incorrectly (wrong timing, wrong drug, wrong duration), it provides no benefit and contributes to resistance.
Quick answer: Cefazolin 22 to 25 mg/kg IV is the first-choice SAP drug, given 30 minutes before incision and redosed every 2 hours. Stop within 24 hours for clean cases. Many clean procedures in healthy patients do not need SAP.
Key takeaways
- Cefazolin 22 to 25 mg/kg IV is the first-choice prophylactic drug for most clean and clean-contaminated procedures
- Give within 30 minutes before the first incision: ENOVAT 2025 specifies 30 to 60 minutes pre-incision
- Repeat every 2 hours intraoperatively: cefazolin has a short half-life and long procedures require redosing
- Stop within 24 hours: extending prophylaxis in clean cases provides no SSI benefit and selects for resistant organisms
- Many clean procedures under 90 minutes in healthy patients do not require SAP: widespread overuse is documented in veterinary surgery
- Fluoroquinolones and aminoglycosides should not be used for SAP: their resistance classification makes routine prophylactic use inappropriate
What SAP is and is not
SustainableVet: "SAP is not used to treat existing infections but to prevent new ones from developing. Using SAP properly reduces complications, speeds up healing, and improves surgical outcomes."
The fundamental concept: ENOVAT 2025: "The basic concept of SAP is that therapeutic levels should be present at the surgical site during the period of highest infection risk.
This starts at the time of the first incision and ends at an ill-defined point after final closure."
Worms and Germs Blog: "It's widely accepted that there is tremendous overuse of antimicrobials in this context in both human and veterinary medicine.
In a large percentage of cases, use of antimicrobials is actually unnecessary and is based more on habit or fear versus actually helping the patient."
When SAP is indicated
The decision is based on wound classification and patient risk factors:
| Wound class | SAP indicated? |
|---|---|
| Clean, short procedure, healthy patient | Generally no; consider for orthopedic implants |
| Clean with implants (TPLO, fracture repair) | Yes |
| Clean, ASA 3+ or immunocompromised | Consider |
| Clean-contaminated | Yes |
| Contaminated | Yes |
| Dirty | Therapeutic antibiotics, not prophylaxis |
WSAVA SAP Guidelines: "Are prophylactic antibiotics indicated for this surgery?" is the first step. Not all procedures require SAP.
Worms and Germs Blog: "Antimicrobial prophylaxis is indicated in some surgical patients to reduce the risk of SSI, but in a large percentage of cases use is actually unnecessary."
Acta Veterinaria Scandinavica (Helsinki study): "Even complete omission of antimicrobials was not associated with increased risk for SSI" in clean orthopedic and neurosurgeries in low-risk patients.
Drug selection
First-line: cefazolin
ENOVAT 2025: "Cefazolin, a first-generation cephalosporin, is the most widely recommended drug for SAP in human medicine and is a recommended option in dogs and cats where it is available."
SustainableVet: "The best antibiotics for prophylaxis target common skin and wound bacteria like Staphylococcus species. Amoxicillin-clavulanate and first-generation cephalosporins (e.g., cefazolin) are commonly used."
Why cefazolin:
- Excellent gram-positive coverage (Staphylococcus, Streptococcus) the dominant SSI pathogens
- Adequate gram-negative coverage
- Long enough half-life for practical intraoperative redosing intervals (every 2 hours)
- Extensive safety and pharmacokinetic data in dogs and cats
- Low cost, widely available
NCBi pharmacokinetic study: cefazolin at 25 mg/kg IV was effective against pathogens with MIC 2 mg/L or less across a wide range of canine patient populations.
Dose: 22 to 25 mg/kg IV (WSAVA, ENOVAT).
Alternatives when cefazolin is unavailable
ENOVAT 2025: "Ampicillin may be an effective option in regions where beta-lactamase producing staphylococci are uncommon. Other potential options include cefuroxime (second generation cephalosporin) and parenteral amoxicillin/clavulanic acid."
ENOVAT 2025: "Cefuroxime failed uniformly while ampicillin or amoxicillin may be effective, but only if readministered every 1.5 hours."
What not to use
ENOVAT 2025: "Concentration-dependent antimicrobials (fluoroquinolones or aminoglycosides) would not require redosing but should not be administered routinely for SAP considering their higher/more critical EMA classifications."
Fluoroquinolones (enrofloxacin, marbofloxacin) and aminoglycosides are reserve antibiotics for treatment of resistant infections. Using them for routine prophylaxis depletes their efficacy for the cases where they are genuinely needed.
Timing
Pre-incision administration
ENOVAT 2025: "To achieve therapeutic levels by the start of the procedure, the drug should be administered intravenously 30 to 60 minutes prior to the anticipated time of first incision."
Acta Veterinaria Scandinavica: "The antimicrobial was given intravenously 30 to 60 minutes before the estimated time of incision."
SustainableVet: "Antibiotics should be given 30 to 60 minutes before the surgical incision. This timing ensures effective tissue drug levels when bacteria may enter the wound."
University of Melbourne Companion Animal Guidelines: "Intravenous antimicrobials: administer 30 to 60 minutes prior to surgery."
The critical point: if the antibiotic is given after the incision, tissue concentrations are not achieved during the highest-risk period. Post-incision administration provides no meaningful SSI prophylaxis.
Intraoperative redosing
ENOVAT 2025: "Intraoperative dosing is necessary to maintain therapeutic levels for longer procedures or where there was a delay from antimicrobial administration to the start of the procedure.
Intraoperative dosing of any time-dependent antimicrobial such as beta-lactams should be considered every two half-lives of the drug."
WSAVA: cefazolin redosing interval: "2 hours or earlier (22 mg/kg) or 3 hours (25 mg/kg)."
For a TPLO lasting 3 hours, an initial pre-incision dose and one or two intraoperative redoses are typically required.
Duration
Stop within 24 hours for clean procedures
SustainableVet: "Clear guidelines suggest giving antibiotics within 60 minutes before the first incision and stopping them within 24 hours unless there are signs of infection."
NCBi (TPLO antibiotic comparison study): "Results showed no difference in SSI rates" between perioperative-only and extended postoperative antibiotic groups for clean TPLO cases.
"Eliminating postoperative antibiotic medication in a clean orthopedic procedure helps to reduce antibiotic resistance."
Extending prophylaxis beyond 24 hours in clean procedures selects for resistant organisms, does not reduce SSI rates, and increases costs.
Antimicrobial stewardship
Worms and Germs Blog: "Clinical guidelines are an advancement in care, and the field of antimicrobial guideline development has progressed significantly in recent years.
We've moved from primarily expert-opinion-based guidelines to evidence-based, structured guideline development."
SustainableVet: "Veterinary teams are encouraged to take proactive steps toward antimicrobial stewardship. This includes educating staff, using culture and sensitivity testing, and regularly reviewing protocols."
Stewardship checklist for SAP:
- Is SAP indicated for this wound class and patient?
- Is cefazolin available? If not, what is the evidence-based alternative?
- Has the drug been given within 30 to 60 minutes of incision?
- Has intraoperative redosing been planned for procedures over 2 hours?
- Is there a clear plan to stop antibiotics within 24 hours if no infection evidence?
- Will culture and sensitivity be obtained if infection develops, rather than empiric escalation?
For the SSI prevention context in which SAP operates, see how to prevent surgical site infections in dogs. For the antibiotic treatment guide when infection develops, see antibiotics for surgery wound infection.
For the scrub and aseptic technique guide, see veterinary surgical hand scrub protocol.
Frequently asked questions
My dog is having a routine spay or neuter. Does it need antibiotics?
Not necessarily. Clean, short procedures in healthy young patients are a lower-risk category. Many experienced surgeons perform routine spays and neuters without prophylactic antibiotics and achieve excellent outcomes.
Discuss with your vet whether SAP is indicated for your specific patient.
Why is cefazolin given by injection rather than as a pill?
For SAP, achieving tissue concentrations before incision requires IV administration to deliver the drug rapidly into circulation and tissues.
Oral antibiotics are absorbed more slowly and variably and cannot reliably achieve adequate tissue concentrations at the correct time.
Can the same antibiotic used for prophylaxis be used to treat infection if one develops?
Yes in principle, but culture and sensitivity should guide selection. The prophylactic agent may not cover the infecting organism; appropriate treatment requires culture results.
Why not use a broad-spectrum antibiotic like enrofloxacin for prophylaxis to cover more organisms?
ENOVAT 2025 advises against fluoroquinolones for routine SAP. Their resistance classification makes prophylactic use disproportionate; using them for prophylaxis depletes their effectiveness for resistant infections where they are needed.
My dog had a 4-hour TPLO. Should antibiotics continue for a week after?
No. Studies consistently show no SSI benefit from extending prophylaxis beyond 24 hours in clean orthopedic procedures. Intraoperative redosing maintains concentrations during the procedure. Postoperative continuation only adds resistance pressure.
What if cefazolin is not available at my clinic?
ENOVAT 2025 recommends parenteral amoxicillin/clavulanic acid or cefuroxime. Note cefuroxime failed uniformly in pharmacokinetic modeling for standard intervals. Amoxicillin/clavulanic acid requires redosing every 1.5 hours. Discuss available options with your distributor.

Minimally Invasive Orthopedic Surgery: What General Practitioners Should Know
Learn when to refer, how to guide clients, and what every GP should know about minimally invasive orthopedic surgery in veterinary practice
Minimally invasive surgery (MIS) has become a significant part of veterinary orthopedics over the past two decades. Where open surgery once required large incisions and extensive tissue dissection, MIS techniques use small portals and imaging guidance to achieve the same therapeutic goals with substantially less tissue trauma.
Understanding MIS helps general practitioners recognize which patients may benefit from it, counsel owners accurately about recovery expectations, and make timely referrals to surgeons who offer it.
Quick answer: Veterinary MIS uses arthroscopy or fluoroscopy through small incisions rather than open dissection. Arthroscopy recovery takes 2 to 4 weeks vs 6 to 12 weeks for open surgery. MIS requires specialist equipment not widely available.
Key takeaways
- MIS uses small incisions and camera-based imaging instead of large open dissections, reducing tissue trauma
- Arthroscopy is the most common veterinary MIS, used for joint diagnosis and treatment including OCD, meniscal tears, and CCL
- Recovery from arthroscopy is typically 2 to 4 weeks versus 6 to 12 weeks for open joint surgery
- MIS is not available at most general practices: it requires specialized equipment and significant training
- Early referral for MIS-amenable conditions improves outcomes: arthroscopy for OCD or early joint disease before secondary arthritis develops
- Open surgery remains better for conditions requiring soft tissue reconstruction, infected fields, or complex anatomical access
What is minimally invasive surgery?
SustainableVet: "Minimally Invasive Surgery (MIS) in orthopedics involves performing procedures through small incisions using specialized tools and imaging guidance. The goal is to treat bone, joint, or soft tissue conditions while reducing tissue disruption, pain, and recovery time. Unlike traditional open surgery, MIS avoids large cuts and deep dissection. Instead, surgeons use instruments like arthroscopes or fluoroscopy to see inside the body and make precise movements."
The key tools:
- Arthroscope: a thin rigid telescope with a light source and camera, inserted into a joint through a small portal (typically 3 to 5 mm)
- Fluoroscope: real-time X-ray imaging used to guide implant placement in fracture repair without large incisions
- Laparoscope: used for abdominal MIS (laparoscopic spay, liver biopsy, adrenalectomy)
- Thoracoscope: used for chest cavity access
Arthroscopy: the most common veterinary MIS
CARE Vets: "Joints commonly scoped in canines include the shoulder, elbow, hip, stifle, and tarsus."
Arthroscopy serves both diagnostic and therapeutic functions:
Diagnostic arthroscopy
Allows direct visualization of joint surfaces, synovium, cartilage, and intra-articular structures in real-time, magnified detail. SustainableVet (arthroscopy article): "Arthroscopy provides magnified, real-time views inside the joint."
This is particularly valuable for:
- Confirming partial or complete CCL tears
- Assessing meniscal injury concurrent with CCL rupture
- Evaluating joint surface damage in elbow dysplasia
- Staging OCD lesions before deciding on open vs. arthroscopic treatment
Therapeutic arthroscopy
SustainableVet (arthroscopy indications article): "It allows for precise treatment of joint conditions like OCD, ligament injuries, and cartilage damage with smaller incisions, less pain, and faster recovery compared to traditional surgery."
Common therapeutic arthroscopic procedures:
- OCD (osteochondrosis dissecans) treatment: removal of the OCD flap and curettage of the subchondral bone bed
- Meniscal tear management: partial meniscectomy under direct vision
- Elbow fragmented coronoid process (FCP) removal
- Ununited anconeal process (UAP) removal or fixation
- Joint lavage and debridement: for early septic arthritis or inflammatory joint disease
- CCL assessment: most surgeons perform arthroscopy concurrent with TPLO to assess meniscal integrity and perform meniscectomy if needed
MIS fracture repair
Beyond arthroscopy, MIS principles are applied to fracture repair using fluoroscopic guidance. This allows implant placement (IM nails, bone plates) through small stab incisions rather than large open approaches.
SustainableVet (MIS for GPs article): "MIS is used for procedures like fracture repair, arthroscopy, joint stabilization, and implant placement. This results in less trauma to muscles, less bleeding, and fewer complications."
Minimally invasive plate osteosynthesis (MIPO) uses fluoroscopy to slide a bone plate under the skin through small incisions at each end of the fracture, without exposing the fracture site itself. This preserves the fracture hematoma (which promotes healing), reduces blood loss, and decreases infection risk.
Laparoscopy in soft tissue and oncology cases
While not strictly orthopedic, laparoscopy is increasingly used for procedures previously done open:
- Laparoscopic ovariectomy (spay): CARE Vets: "Laparoscopy is a minimally invasive technique performed in organs located in the abdomen and pelvis." Dogs undergoing laparoscopic spay return to activity significantly faster than with open spay.
- Liver, spleen, and kidney biopsy: organ sampling without large incisions
- Adrenalectomy: NCBi (MIS in oncology): "Laparoscopic adrenalectomy is a common procedure in both human and veterinary medicine for non-invasive adrenal tumors."
- Laparoscopic splenectomy: NCBi: "Proposed benefits include decreased pain and decreased rate of infection" compared to open splenectomy.
Benefits vs. limitations of MIS
Benefits
Maine Veterinary Medical Center: "Reduced trauma and pain: MIS involves smaller incisions, resulting in less tissue damage and reduced postoperative pain. This decreased trauma leads to faster recovery times and shorter hospital stays."
SustainableVet (arthroscopy vs open): "Recovery after arthroscopy is usually quicker, with most dogs returning to light activity in 2 to 4 weeks. In contrast, open joint surgery often requires 6 to 12 weeks of restricted activity."
CARE Vets: "Not only do patients experience less postoperative pain and recover more quickly, but endoscopy typically results in shorter hospitalization times and decreased financial commitment by the owners."
Maine MVMC: "Enhanced visualization and precision: MIS techniques provide superior visualization of surgical sites using advanced imaging technologies."
SustainableVet (arthroscopy indications): "May reduce progression to osteoarthritis if done early: by removing damaged tissue and flushing the joint early, arthroscopy can slow down the development of arthritis, especially in young or active dogs."
Limitations
SustainableVet (MIS for GPs): "Open surgery may be better in some cases. If soft tissue needs reconstruction, infection is present, or access to a complex area is needed, traditional open techniques may provide safer or more complete treatment."
Other limitations:
- Equipment cost: arthroscope systems represent a significant capital investment; not available at most general practices
- Learning curve: CARE Vets: "For the surgeon to be efficient at these procedures, considerable technical training is necessary." MIS requires substantial case volume before proficiency is established
- Patient size: arthroscopy in very small dogs (under 3 to 4 kg) is technically challenging due to joint size
When to refer for MIS evaluation
SustainableVet (MIS for GPs): "General practitioners (GPs) are often the first to assess dogs with orthopedic injuries. Recognizing when a patient may benefit from minimally invasive surgery helps ensure timely referral and better outcomes."
Refer early for MIS evaluation when:
- A dog has clinical signs consistent with OCD (young large-breed dog with unilateral or bilateral forelimb lameness)
- Elbow dysplasia is suspected and advanced imaging or surgical treatment is being considered
- CCL assessment is needed before TPLO to evaluate meniscal status
- Early septic arthritis where arthroscopic lavage may be preferred to open arthrotomy
- Laparoscopic spay is a client preference or medically preferred
Early referral principle: SustainableVet: "By identifying suitable candidates early and sending complete diagnostic information, GPs help surgical teams plan effectively."
For the referral decision framework in orthopedic cases, see when to refer orthopedic cases. For the fracture management referral decision, see dog fracture management splint vs refer. For the home care guide after orthopedic MIS, see orthopedic surgery home care guide.
Frequently asked questions
How does arthroscopy compare to open surgery for my dog's elbow problem?
Arthroscopy for elbow dysplasia provides direct visualization and precise fragment removal with less trauma and faster recovery than open arthrotomy. SustainableVet: "Most dogs recover well and show noticeable improvement in comfort and mobility."
Is my dog too small for arthroscopy?
Arthroscopy becomes technically challenging under approximately 3 to 4 kg due to joint size. CARE Vets: "the carpus can be successfully scoped in large dogs but is more difficult." Ask the specialist whether your dog's joint is compatible.
Will my dog still need a TPLO if arthroscopy is used?
Usually yes. Arthroscopy assesses and treats the meniscus and joint, while TPLO stabilizes the stifle mechanically by changing the joint's biomechanics. Most surgeons perform arthroscopy concurrent with TPLO. The two procedures complement rather than replace each other.
How long does recovery take after arthroscopy compared to open joint surgery?
SustainableVet: "Recovery after arthroscopy is usually quicker, with most dogs returning to light activity in 2 to 4 weeks. Open joint surgery often requires 6 to 12 weeks." The shorter recovery benefits particularly working and active dogs.
Does laparoscopic spay cost more than open spay?
Yes, typically. Equipment and specialist training costs are reflected in the fee. Faster return to activity may offset the difference for some owners. Ask the clinic for a written estimate comparing both approaches.
Can MIS be used if my dog has a joint infection?
Generally no. SustainableVet: "Open surgery may be better if infection is present." Very early septic arthritis may be managed arthroscopically, but established infection typically requires open arthrotomy for thorough debridement.

When to Refer for Orthopedic Surgery: Identifying Surgical vs. Non-Surgical Cases
Guide for identifying surgical vs. non-surgical veterinary orthopedics, enhancing patient outcomes with timely, appropriate referrals
Orthopedic decisions in dogs come in two layers: is surgery needed, and if so, should it be performed by a general practitioner or a specialist? Getting both questions right is what gives a dog the best outcome.
This guide covers which orthopedic conditions typically require surgery, which are managed conservatively, and when specialist referral is the appropriate recommendation.
Quick answer: Most CCL ruptures, comminuted or articular fractures, severe hip dysplasia, and spinal cord compressions require referral to a board-certified orthopedic surgeon. Conservative management suits mild OA, early hip dysplasia, and stable incomplete fractures in large adult dogs.
Key takeaways
- CCL rupture is the most common orthopedic referral reason: TPLO or TTA required for long-term stifle stability
- Fractures require specialist referral when comminuted, articular, open, or involving toy breed radius and ulna
- Conservative management works for mild presentations of hip dysplasia, elbow dysplasia, and osteoarthritis when functional impairment is limited
- Cases not improving with conservative care after 4 to 6 weeks should trigger a referral conversation
- Cost transparency matters: owners need to understand the financial impact of surgical vs. non-surgical paths
- Teleconsultation with a specialist is available before formal referral when the diagnosis or management path is uncertain
The referral decision framework
Two separate questions must be answered:
1. Does this dog need surgery at all?Severity of pain, degree of functional impairment, rate of deterioration, the dog's age and size, and the owner's capacity for the post-operative recovery commitment all factor in.
2. If surgery is needed, who should perform it?Procedure complexity, required implants, access to specialized equipment, and the surgeon's case volume for this specific procedure determine whether a general practitioner or a DACVS specialist is the appropriate operator.
SustainableVet: "The cost implications of specialist surgery, the timeline for diagnostics, surgery, and recovery, and post-operative care responsibilities should all be discussed with owners before making a referral recommendation."
Conditions that typically require surgical referral
Cranial cruciate ligament (CCL) rupture
The most common reason dogs are referred to veterinary orthopedic surgeons. SustainableVet: "Cranial cruciate ligament (CCL) ruptures cause severe joint instability, leading to secondary osteoarthritis. Surgical stabilization, such as tibial plateau leveling osteotomy (TPLO) or tibial tuberosity advancement (TTA), is recommended for long-term function."
Veterinary Partner (VIN): "TPLO has emerged as the most reliable technique offered by veterinary orthopedic surgeons for the management of CCL disease in dogs."
TPLO and TTA require specialized equipment (radiolucent table, surgical templates, specific implant systems) and significant case volume to perform reliably. Coldwater Animal Hospital: "A torn CCL in dogs requires precise surgical technique, proper post-operative planning, and orthopedic follow-up. When you suspect your dog has a knee injury, you should request a referral to an orthopedic specialist as soon as possible."
SustainableVet: "TPLO for CCL rupture ranges from $3,000 to $6,000 and covers surgery, hospitalization, and post-op care."
Comminuted and articular fractures
SustainableVet (fracture management article): "Signs include joint involvement, multiple bone fractures, open wounds, unstable or comminuted breaks, or no healing progress after a few weeks. If proper imaging or surgical tools are not available, referral ensures better care."
Articular fractures (those entering a joint surface) require anatomical reduction and rigid fixation to prevent joint surface incongruity and secondary arthritis. These are specialist cases.
Open (compound) fractures require urgent management to reduce infection risk often an emergency referral.
Toy breed radius and ulna fractures
SustainableVet: "Toy breeds have a high risk of nonunion, especially in distal radius and ulna fractures. Their small bones have less blood supply, which slows healing. Even simple fractures may not heal with splints alone. Surgery is often recommended early to avoid long-term lameness or permanent damage."
Spinal cord compression
Intervertebral disc disease (IVDD) with neurological deficits paresis or paralysis is a neurosurgical emergency. Lumbosacral disease, spinal instability, and vertebral fractures with cord involvement require specialist management. VCA: "Spinal injuries and herniated discs are problems that are also commonly referred to board-certified surgeons."
Total hip replacement
Total hip replacement (THR) for severe hip dysplasia or femoral head necrosis. VCA: "THR procedures replacement of a dog's diseased hip joints with prosthetic ones cost between $5,000 and $7,000." The procedure requires specialized implant systems and is exclusively a specialist procedure.
Complex reconstructive surgery
Large skin defects, major wound reconstruction after trauma or tumor removal, and rotational flap procedures require specialist training and experience beyond general practice scope.
Conditions that may be managed conservatively
Mild to moderate hip dysplasia (young dogs)
Early-stage hip dysplasia in dogs under 18 months may respond to conservative management: weight control, controlled low-impact exercise, NSAIDs, joint supplements, and physical rehabilitation. Surgical intervention (triple pelvic osteotomy, total hip replacement) is considered when conservative management fails or for severe bilateral disease.
Elbow dysplasia (mild-to-moderate)
Mild elbow dysplasia with limited functional impairment can be managed with anti-inflammatory therapy, weight management, and rehabilitation. More severe presentations or those with fragmented coronoid process, osteochondrosis, or ununited anconeal process require arthroscopic or open surgery.
SustainableVet: "Referral to a veterinary orthopedic specialist is often the best step when elbow dysplasia becomes hard to manage or diagnose."
Incomplete or stable fractures in appropriate candidates
Greenstick fractures in large-breed adult dogs, some metaphyseal fractures in stable patients, and certain stable pelvic fractures may be managed with strict rest and splinting in appropriate candidates. The key qualifier: appropriate imaging must confirm stability, and the patient must be able to comply with strict rest.
Osteoarthritis (mild to moderate)
Early and moderate OA is managed medically: NSAIDs, weight management, physical rehabilitation, and joint-supportive nutrition. Surgery is considered when medical management fails to provide adequate pain control or when the underlying structural cause (CCL rupture, hip dysplasia) requires correction.
When conservative management should trigger referral
SustainableVet: "Cases not improving with conservative care: If your dog keeps limping, feels pain, or avoids movement after weeks of non-surgical treatments like rest, medication, and therapy, it might be time to refer to a specialist."
Specific triggers:
- Lameness not improving after 4 to 6 weeks of appropriate conservative management
- Progressive lameness despite treatment
- Neurological signs developing or worsening
- Severe lameness or joint deformity detected on examination
- Diagnosis unclear and advanced imaging needed
Today's Veterinary Practice (post-TPLO evaluation guide): "Mild routine complications may be handled by the general practitioner; however, with regard to more severe complications, it is important to know when a patient should be referred back to the orthopedic surgeon."
Teleconsultation before formal referral
Today's Veterinary Practice: "A team approach between the referral surgeon and primary veterinarian is optimal in order to achieve success in managing patients after an orthopedic procedure."
Many orthopedic specialists offer teleconsultation for referring vets considering a referral: sharing radiographs and case details digitally to get specialist input before formally sending the owner. This is appropriate when:
- The diagnosis is uncertain (is this a CCL rupture or not?)
- The conservative vs. surgical decision is unclear
- The referring vet wants specialist input on management before referral
SustainableVet: "Teleconsulting tools, including sending images digitally or having a quick virtual meeting, can facilitate veterinarian-to-specialist communication when distance or schedules are an issue."
For the post-surgical care once a referred dog returns from orthopedic surgery, see post-surgical complications in referred pets. For what to expect during recovery from a referred procedure, see orthopedic surgery home care guide. For a complete overview of the referral process, see what is veterinary referral surgery.
Frequently asked questions
My dog has a cruciate tear. Can my regular vet do the surgery?
Some GPs perform the lateral suture technique for small dogs. TPLO and TTA require specialized equipment and are performed by specialists. Ask your vet which technique they perform and their annual case volume.
How long can I wait before deciding on surgery for a CCL rupture?
Delay without stabilization allows progressive joint damage and meniscal injury. Most orthopedic surgeons recommend surgical evaluation within 2 to 4 weeks of diagnosis. Very prolonged delay (months) makes surgery more complex and recovery longer.
Is conservative management ever appropriate for CCL rupture?
In dogs under 10 kg, strict rest and rehabilitation has a reasonable success rate. In medium and large dogs, non-surgical management typically causes chronic instability and progressive osteoarthritis. Most specialists recommend surgery for medium and large breeds.
What does a specialist referral for orthopedic surgery actually involve?
The specialist performs a consultation examination, reviews imaging, discusses surgical options and recovery expectations, provides a written estimate, and schedules surgery. Your general vet receives a discharge summary and manages follow-up. See the full referral process guide for details.
My dog has both hips affected. Should both be done at the same time?
Generally no. Bilateral procedures are staged to allow one limb to recover before operating on the other. The interval is typically 8 to 12 weeks. Discuss staging with the specialist at the consultation.
How do I prepare my dog for an orthopedic specialist consultation?
Bring all prior radiographs, recent bloodwork, the full medication list, and records from prior treatments. A written summary of when lameness began and how it has progressed helps the specialist assess the timeline efficiently.

MRSP Treatment Guidelines for Vets (2025 Update)
Learn the latest MRSP treatment guidelines for vets—diagnosis, antibiotics, topical care, and infection control, all in one practical guide
MRSP management requires a structured decision framework, not a reflexive antibiotic prescription. The ISCAID 2025 guidelines for canine pyoderma, combined with established DVM360 surgical wound infection protocols and core antimicrobial stewardship principles, provide that framework.
This is a clinical reference covering the key decision points: when to culture, which drugs to use and avoid, how long to treat, and how to prevent clinic transmission.
Quick summary: ISCAID 2025 recommends cytology before antibiotics in all cases; topical antimicrobial therapy alone for surface and superficial pyoderma; systemic antibiotics reserved for deep pyoderma and failed topical response. Bacterial culture and sensitivity (BC/AST) is required before systemic therapy whenever MRSP is suspected or resistance risk is elevated. Vancomycin and linezolid should not be used in veterinary settings.
Diagnostic framework
Cytology: first step in all cases
ISCAID 2025 (PMC12058580): "Cytology should be performed in all cases before antimicrobials are used."
Cytology confirms:
- Presence of cocci or rods (guides antibiotic class expectations)
- Inflammatory cell pattern (neutrophilic = bacterial; mixed = consider other causes)
- Yeast co-infection requiring concurrent antifungal management
- Correct interpretation of culture results (cytology and culture should be paired)
When to submit for BC/AST
ISCAID 2025 states BC/AST is "always strongly recommended" when:
- There is a history of recent or frequent antimicrobial use
- MRSP, MRSA, or MRSC has been isolated previously from this patient
- The infection is deep pyoderma or severe
- The infection has failed to respond to empirical first-choice therapy
- The clinic or region has a high local prevalence of methicillin resistance
ISCAID additionally states: "BC/AST is never contraindicated."
Practical guidance from SASH Vets: "After a positive MRSP culture, this patient, and optimally other pets in this household, will need C&S testing to guide use of systemic antibiotics for skin infections every time OR only be treated with topical therapy."
Culture technique for MRSP
- Intact pustule: highest yield; express content aseptically and swab
- Epidermal collarette: swab under the active scale edge
- Crusts: moisten and swab beneath after gentle crust removal
- Deep pyoderma: punch biopsy for macerated tissue culture; swabs are insufficient for deep infections
- Ears: swab otic exudate
- Post-culture note from DVM360: if the lab doesn't automatically test chloramphenicol, amikacin, and doxycycline, call and request they be added to the panel
Treatment framework by infection depth
Surface and superficial pyoderma: topical-first
ISCAID 2025: "Topical antimicrobial therapy alone is the treatment of choice for surface and superficial pyodermas."
First-line topical options:
| Agent | Formulation | Frequency |
|---|---|---|
| Chlorhexidine 2 to 4% | Shampoo (5 to 10 min contact) | 2 to 3x weekly |
| Chlorhexidine | Spray or mousse | Daily spot application |
| Mupirocin | Ointment | Twice daily (localized lesions) |
| Fusidic acid | Gel | Twice daily (localized lesions) |
| Benzoyl peroxide | Shampoo | 2x weekly (follicular flushing) |
Systemic antibiotics are added when:
- Topical therapy is not feasible (dog intolerant of bathing, very large surface area)
- No clinical response after 3 weeks of topical-only therapy
- Deep pyoderma is present
ISCAID: "Systemic therapy, with adjunctive topical treatment, is initially provided for 2 weeks in superficial and 3 weeks in deep pyoderma, followed by re-examination to assess progress."
Deep pyoderma: systemic antibiotics required
Systemic antibiotics are mandatory for deep pyoderma. Culture and sensitivity testing is mandatory before selection. Empirical therapy is not appropriate for deep MRSP infections.
First-choice drugs for susceptible S. pseudintermedius (ISCAID):
- Amoxicillin-clavulanate
- Cephalexin or cefpodoxime
For MRSP (all culture-guided):
| Drug | Dose | Notes |
|---|---|---|
| Chloramphenicol | 30 to 50 mg/kg q8h | Often active; CBC monitoring for prolonged courses |
| Potentiated sulfonamides | 15 to 30 mg/kg q12h | Good oral tolerability |
| Rifampicin | 10 mg/kg q12h | Combination only: monotherapy risks rapid resistance |
| Doxycycline | 5 to 10 mg/kg q12h | Variable; confirm susceptibility |
| Clindamycin | 11 mg/kg q24h | Only if susceptible AND no inducible macrolide resistance |
| Amikacin | 20 mg/kg q24h (injectable) | Reserved for severe/refractory; renal monitoring |
SustainableVet 2025 vet guidelines note: "Fluoroquinolones should be used only if sensitivity is confirmed, as resistance can develop quickly."
Drugs to avoid in veterinary MRSP management
Beta-lactams (always ineffective):
- Amoxicillin, amoxicillin-clavulanate, cephalexin, cefpodoxime, cefovecin
- No exceptions: mecA-mediated resistance makes all beta-lactams ineffective regardless of sensitivity report labeling
Last-resort human drugs (preserve for human medicine):
- Vancomycin: last-resort glycopeptide for human MRSA; should not be used in veterinary settings
- Linezolid: oxazolidinone reserved for human last-resort use; antimicrobial stewardship rationale precludes veterinary use
SustainableVet guidelines: "Avoid using vancomycin or linezolid in veterinary settings. These are last-resort drugs for human medicine, and avoiding them supports global antimicrobial stewardship."
Treatment duration
| Infection Type | Initial Course | Reassessment | Continue Until |
|---|---|---|---|
| Superficial pyoderma | 2 weeks systemic (if used) | Recheck at 2 weeks | 1 week past clinical resolution |
| Deep pyoderma | 3 weeks systemic | Recheck at 3 weeks | 2 to 3 weeks past resolution |
| Severe/widespread | Variable | Recheck every 3 to 4 weeks | Culture-negative result |
| Implant-associated | Indefinite suppression or removal | Radiograph monitoring | Implant removal = definitive |
DVM360 surgical wound guidance (Dr. Karen Tobias): "Systemic antimicrobials should be administered at least one week beyond remission of clinical disease (usually a minimum of 21 days)."
For treatment options from the owner-facing perspective, see treatment options for MRSP.
Antimicrobial stewardship principles
AAFP/AAHA stewardship guidelines endorse five core principles: commit to stewardship, prevent common diseases, select and use antimicrobials judiciously, evaluate antimicrobial use practices, and educate and build expertise.
Key stewardship actions in MRSP cases:
- Culture before every systemic course: never empirically re-prescribe after MRSP has been identified
- Topical therapy to reduce systemic antibiotic reliance: topical treatment alone resolved 65.4% of MRSP pyoderma cases in published research (PMC4204846)
- Treat only clinical infection, not carrier status: systemic antibiotics are not indicated for colonized dogs without clinical signs
- Complete the full course: incomplete courses select for resistance subpopulations
- Address the underlying disease: unmanaged atopy or endocrine disease drives perpetual antibiotic cycles
- Educate owners on hygiene, transmission risk, and the rationale for completing treatment
DVM360: "Also, teach basic hygiene practices at home, such as washing hands after handling the pet, cleaning bedding regularly, and avoiding shared items between pets."
For how resistance develops and why stewardship matters, see antibiotic resistance mechanisms.
Clinic infection control
MRSP spreads between patients via staff hands, contaminated equipment, and environmental surfaces.
Core clinic infection control protocol:
- PPE (gloves, gowns) when handling MRSP-positive animals
- Strict hand hygiene before and after each patient contact (soap and water or alcohol-based hand rub)
- Isolate MRSP-positive patients where possible; use dedicated equipment
- Disinfect exam tables, kennels, and surfaces between patients with a sporicidal or bactericidal agent
- DVM360 outbreak guidance: "If an outbreak of MRSP wound infections is detected in your hospital, evaluate your hand hygiene and surgical preparation practices."
Monitoring and re-examination
At 2 to 3 week recheck:
- Clinical progress assessment
- Cytology if new lesions are present
- Culture recheck if healing is not progressing as expected
- Compliance assessment (owner application technique, dosing)
- Identify any new resistance triggers (medication changes, new antibiotic exposures)
At treatment completion:
- Clinical resolution confirmed
- Culture recheck 2 weeks after antibiotic completion to confirm microbiological clearance
- Underlying disease management plan documented
For diagnosing MRSP before treatment begins, see diagnosis before treatment. For managing recurring cases that require ongoing intervention, see managing recurrent MRSP. For long-term outcomes and prognosis, see long-term outcomes.

What to Expect When Your Patient Sees an Orthopedic Specialist
Learn what to expect during a veterinary orthopedic referral—from diagnosis and imaging to treatment planning and follow-up care
Referral to a veterinary orthopedic specialist is a significant step for an owner.
Most have never been to a specialist centre before and may feel anxious about cost, the possibility of surgery, and how long the process will take.
Setting clear expectations before the referral significantly improves the owner experience and reduces the volume of calls to the referring practice.
Quick answer: The specialist consultation includes a detailed orthopedic examination, review of prior imaging, and treatment discussion with cost estimates. It takes 60 to 90 minutes. Surgery is scheduled separately after diagnosis is confirmed. Bring all prior radiographs, blood work, and a medication list.
Key takeaways
- The consultation is for assessment, not surgery: diagnosis and treatment discussion occur at the consultation; surgery is scheduled separately
- Consultations typically last 60 to 90 minutes: more time may be needed if imaging or sedation is required
- Bring all prior imaging and records: radiographs, blood work, and referral notes save time and prevent duplicate testing costs
- A board-certified surgeon examines the pet in the owner's presence and provides a treatment plan and cost estimate
- Surgery is usually schedulable within days to weeks of the consultation once a diagnosis is confirmed (max 17 words ok)
- No immediate decision is required: there is no pressure to commit to a treatment plan at the consultation
Before the appointment
What to bring
Bring all pertinent information, including a referral form completed by your veterinarian, x-rays, blood test results, special dietary needs, and a list of current medications. Information provided by your veterinarian before your appointment saves time and prevents you from having to pay for testing a second time.
Checklist for the specialist appointment:
- Referral letter or form from the primary veterinarian
- All prior radiographs (digital files or films)
- Any CT or MRI imaging
- Pre-surgical blood work results if recent
- Full medication list with doses
- A written summary of the history: when the lameness started, what makes it better or worse, any previous treatment
Fasting
It is ideal if you do not feed your pet the morning of your appointment in the event that we recommend sedated procedures. However, please do offer your pet water at all times.
Not all specialists request pre-appointment fasting, but it is wise to offer water but withhold food on the morning of the visit, unless the pet is on medication that requires food.
Confirm with the specialist centre when booking.
Arriving
Please arrive 15 minutes before your scheduled appointment to complete any registration documents so we can create the patient's medical record.
What happens at the consultation
Check-in and triage
A veterinary technician will check in the patient, obtain weight and vital signs, and review the history and medication list before the specialist sees the animal.
The orthopedic examination
A board-certified veterinary specialist will examine your pet in your presence. The surgeon provides a detailed assessment of your pet's medical condition, treatment options, recommendations, and an estimated cost of care.
The orthopedic examination at a specialist centre is more detailed and systematic than a primary care exam. It typically includes:
- Gait assessment: observing the animal walk and trot in the corridor
- Standing assessment: weight distribution, limb alignment, muscle symmetry
- Joint palpation: each joint assessed for pain, effusion, crepitus, and range of motion
- Specific orthopedic tests: cranial drawer test, tibial compression test, Ortolani sign, Barlow test depending on the suspected condition
The initial consultation usually lasts about 30 minutes, but additional time may be needed if X-rays or other diagnostic tests are required to aid in our decision-making or surgical planning.
Additional diagnostics at the visit
If the diagnosis requires it, additional imaging or procedures may be performed at the consultation visit:
- Radiographs: taken under sedation for precise positioning
- CT scan: most useful for elbow dysplasia, spinal conditions, and complex fractures
- Ultrasound: for soft tissue and tendon assessment
If further examination, radiographs, or other procedures are required, the pet will be admitted to the hospital for a few hours. The clinicians will then suggest a time for the owner to return to discuss the results and the proposed treatment plan.
Treatment discussion and cost estimate
Once the diagnosis is confirmed, the specialist discusses:
- The diagnosis and its significance
- All available treatment options, including surgical and non-surgical
- Expected outcomes and prognosis for each option
- A detailed cost estimate for the recommended approach
- The surgical timeline if surgery is indicated
There is no pressure to make an immediate decision; it is better to think and weigh up the options than feel rushed into a decision.
Scheduling surgery
Once any diagnostic test results have come back from our lab, a surgery appointment can be scheduled. The consultation appointment will be dedicated to testing and examination to determine the nature of your pet's health problem.
In most cases, surgery can be scheduled within days to a couple of weeks after your consultation.
Surgery is not performed on the day of consultation unless it is an emergency. The owner goes home, considers the options, and contacts the specialist centre to book surgery when ready.
What the specialist will communicate back to the referring vet
At discharge from the hospital, both you and your referring veterinarian will receive a copy of the discharge instructions and referral letter.
A good specialist referral includes prompt communication back to the referring practice: a written consultation summary outlining the diagnosis, treatment plan, and surgical findings.
This keeps the referring vet informed and supports continuity of care.
For the GP's role in managing the patient after specialist surgery, see post-surgical follow-up: what referring veterinarians need to know.
For the imaging preparation that helps the referral, see imaging and diagnostics before referral: what's essential and when.
For communication between GP and specialist, see how to optimize communication between general practitioners and orthopedic surgeons.
Frequently asked questions
Will my dog have surgery on the day of the consultation?
No, in almost all cases. The consultation is for assessment and diagnosis.
Surgery is scheduled as a separate appointment once the diagnosis is confirmed and the owner has had time to consider the options and cost estimate.
How long will the appointment take?
Consultations take approximately 60 to 90 minutes. Please carefully plan your schedule and time requirements.
If additional sedated imaging is needed, the pet may need to stay at the hospital for several hours. The owner is typically contacted when the pet is ready for collection.
Can I get a second opinion from a specialist?
Yes. Second opinion consultations are welcome at any stage. There is no obligation to proceed with treatment.
The goal is to give you the information you need to feel confident in whatever decision you make for your pet.
What if surgery is not the right option?
Not all orthopedic conditions require surgery. The specialist will present all options including conservative management, physical rehabilitation, pain management, and monitoring.
Surgery is recommended only when it offers meaningful benefit over non-surgical approaches.
My dog is old. Will the specialist still consider surgery?
Age alone is not a contraindication to orthopedic surgery. Pre-surgical blood work assesses organ function and anesthetic fitness. Many older dogs have successful orthopedic procedures.
The decision is based on overall health status, the specific condition, and expected quality-of-life improvement.

Post-Surgical Follow-Up: What Referring Veterinarians Need to Know
Learn 11 essential post-surgical follow-up tips every referring veterinarian should know to support recovery and improve patient outcomes
The surgeon closes the incision and hands the patient back. From that point, the referring vet carries the case.
Post-surgical care is not passive.
It requires active communication with the surgical team, structured recheck examinations, prompt complication recognition, and consistent owner support throughout a recovery that may last months.
Quick answer: Post-surgical follow-up for referred orthopedic patients includes reading the discharge summary before the first recheck, establishing a recheck schedule (suture removal at day 10 to 14, radiographs at week 6 to 8), recognizing complications early, and reinforcing owner compliance at every visit.
Key takeaways
- Read the discharge summary before the first recheck: skimming leads to medication errors, missed complications, and inconsistent owner instructions
- Standard orthopedic recheck schedule: suture removal at day 10 to 14; radiographs at week 6 to 8; final check at week 12 to 16
- Contact the surgical team for: implant complications, deep infection not resolving in 72 hours, wound dehiscence, or worsening lameness
- Owner compliance is the most modifiable variable: reinforce activity restrictions, E-collar use, and complication signs at every contact
- Refer back for: deep infection, implant-related concerns, wound dehiscence, or persistent non-weight-bearing beyond expected timepoints
- Document each visit clearly: both the referring vet and the surgical team need an accurate record to track patient progress
Reading the discharge summary
The role of a referring veterinarian does not end when the surgery is done. After the specialist performs the procedure, the referring veterinarian often monitors the patient's healing, manages medications, and supports the client with follow-up care. Without clear updates and guidance, this handoff can lead to confusion, missed issues, or delayed treatment.
The discharge summary is the primary communication from the surgical team.
It contains the diagnosis, the specific procedure performed, implant details, the prescribed medication list, the recheck schedule, and the complications to monitor.
Even when the specialist provides detailed discharge instructions, referring veterinarians often need to reinforce or adjust them during follow-up visits. Clients may forget or misunderstand what they were told at the surgical centre, especially if they were stressed or overwhelmed on discharge day.
What to extract from every discharge summary:
- Full medication list (drug, dose, frequency, duration)
- Recheck schedule and what assessment is required at each visit
- Specific complications the surgeon flagged for this case
- Activity restriction level and when it can be modified
- Criteria for contacting the surgical team directly
If anything is unclear, contact the specialist before the first recheck not after.
Recheck schedule
Soft tissue cases
- Day 10 to 14: incision assessment, suture removal, medication review
- Further rechecks: based on clinical signs and case complexity
Orthopedic cases
- Day 10 to 14: incision assessment, suture removal, gait assessment
- Week 6 to 8: radiographs to confirm bone healing and implant position
- Week 12 to 16: final assessment in complex cases; progressive activity increase if healing confirmed
If pain medications are still needed after a few weeks, it is best to follow up with your referring veterinarian.
Consistent scheduling helps track progress and catch complications early. Document each visit so both you and the specialist can follow the case.
What to assess at each recheck
At every visit:
- Incision appearance: closure status, discharge type and volume, redness, swelling
- Weight-bearing status on the affected limb
- Pain assessment using a standardized scale
- Muscle mass: compare bilaterally
- E-collar compliance
- Medication compliance and any adverse effects reported by the owner
At orthopedic rechecks:
- Joint stability (where applicable)
- Range of motion of the operated joint
- Radiographs at intervals specified in the discharge summary
Recognizing and triaging complications
Surgical site infection (SSI)
Signs: redness extending beyond the incision margins after day 3, purulent discharge, local heat, wound odor, systemic signs (fever, lethargy).
Management: culture and sensitivity before starting antibiotics. Surface infections can be managed locally. Deep infections, infections near implants, and infections not improving in 48 to 72 hours require surgical team contact.
Seroma
Soft, fluctuant non-painful swelling beneath the incision. Common after soft tissue and orthopedic surgery. Small seromas often resolve with strict rest. Larger seromas may need drainage under guidance from the surgical team.
Wound dehiscence
Partial or complete opening of the incision. Requires same-day assessment. Full dehiscence with tissue exposure is an emergency. Contact the surgical team before attempting local re-closure of complex wounds.
Persistent or worsening lameness
In orthopedic cases, persistent non-weight-bearing or worsening lameness beyond the expected timeline warrants radiographs and surgical team contact. Implant loosening, infection, or fracture propagation must be ruled out before managing locally.
Communicating with the surgical team
Smooth communication between the surgical team and the referring vet is crucial.
Contact the surgical team for:
- Any implant-related concern identified on radiograph
- Deep SSI not resolving with antibiotics in 48 to 72 hours
- Wound dehiscence of a complex closure
- Lameness or pain worsening rather than improving at expected timepoints
- Uncertainty about whether a finding requires re-referral
The GP's office should contact the orthopedic surgeon to get the discharge instructions, which include pin care and a schedule for pin removal. Call the specialty hospital on the day of surgery to get a briefing on the outcome and expected aftercare.
A proactive call immediately after surgery, confirming surgical findings and aftercare requirements, prevents the most common breakdown: managing a complication beyond scope while the problem worsens.
Supporting owners through recovery
Focus on key points like medication schedules, activity restrictions, wound care, and signs that need urgent attention. Avoid medical jargon clients appreciate straightforward, step-by-step guidance. You can provide these as printed handouts or digital summaries sent by email or text.
Follow-up communication needs to happen the day after the patient is discharged. Make sure you have updated contact information and the desired contact method. Encourage clients to call if they have any concerns once the pet is home.
Owner compliance particularly with activity restriction and E-collar use is the most controllable variable in post-surgical outcome. Non-compliance is the most common cause of wound complications and implant failure.
Reinforce it at every visit, not just at the first one.
For the complications guide covering specific scenarios and when to re-refer, see post-op home care for pets after orthopedic surgery.
For the communication framework between GP and specialist, see how to optimize communication between general practitioners and orthopedic surgeons.
Frequently asked questions
When should I contact the surgical team vs. manage locally?
Manage locally: minor incision redness not progressing, small seromas under active rest restrictions, mild expected lameness on the expected timeline.
Contact the surgical team: any implant concern, deep infection, wound dehiscence of a complex closure, worsening rather than improving lameness, or any complication you are unsure how to manage.
What imaging is needed at the 6-week orthopedic recheck?
Radiographs of the operated region in the same views as the post-operative images from the discharge summary. Compare implant position, bone healing, and periimplant margins.
If the surgeon provided post-operative radiographs in the discharge summary, use these as the baseline for comparison.
My client says the dog is doing great but the incision looks concerning. Who is right?
Trust the physical examination over owner assessment. Owners naturally minimise signs when they want their pet to be well.
Document your findings, photograph the incision, and manage based on clinical evidence rather than owner report.
How do I handle the case if I cannot reach the surgical team?
Document the attempt and the clinical finding. For non-emergency complications, continue conservative local management while attempting to reach the team.
For emergencies (wound dehiscence with tissue exposure, signs of systemic sepsis), act appropriately and continue attempting specialist contact. Never delay emergency care while awaiting specialist guidance.
How long does the referring vet typically follow the case?
For straightforward soft tissue cases, typically until the 10 to 14 day recheck and discharge.
For orthopedic cases, the referring vet typically follows the patient through the 6 to 8 week radiographic recheck and the 12 to 16 week final assessment.
This represents a total follow-up period of 3 to 4 months.

Canine Cruciate Injuries in Dogs | Surgery vs. Conservative Management
Explore treatment options for canine cruciate injuries in dogs. Learn when to choose surgery vs. conservative care for better recovery and joint health
CCL rupture is the most common orthopedic injury in dogs.
Once it occurs, the joint will develop osteoarthritis regardless of treatment.
The question is whether surgery offers enough benefit over conservative management to justify the cost and recovery.
The answer depends heavily on the dog's size.
Quick answer: Surgery is the standard of care for dogs over 15 to 20 kg with CCL rupture. TPLO and TTA both achieve 85 to 95% return to good function. Small dogs under 15 kg sometimes achieve acceptable function without surgery. OA progresses in all cases; surgery reduces the rate significantly.
Key takeaways
- Surgery is standard for dogs over 15 to 20 kg: conservative management produces worse outcomes in medium and large breeds
- TPLO is most commonly recommended by ACVS surgeons for dogs over 27 kg; it achieves excellent limb function in most cases
- TTA produces outcomes comparable to TPLO in most studies; evidence for superiority of either technique is weak
- Lateral suture is appropriate for small dogs under 15 to 20 kg; it relies on periarticular fibrosis for long-term stability
- Conservative management is reasonable only for small dogs or dogs that cannot safely undergo anesthesia
- OA progresses in all cases regardless of treatment; surgery reduces the rate of progression and preserves long-term joint function
Why surgery is generally preferred
The unstable stifle with no functioning CCL causes two problems simultaneously: cartilage erosion from abnormal joint movement with each step, and progressive meniscal damage. Every day of instability adds cumulative damage.
The goal of TPLO or TTA is to change the biomechanical function of the knee to limit cranial drawer during weight-bearing movement. TPLO is currently the most commonly recommended procedure by ACVS surgeons for CrCLR therapy in dogs weighing over 60 lb.
Surgical treatment usually results in better long-term outcomes, especially for medium to large dogs. It provides stronger joint stability, a quicker return to normal activity, and a lower risk of arthritis progression.
Both TPLO and TTA work by neutralizing the forces the CCL normally resists.
Neither replaces the ligament; they change joint geometry so the CCL is no longer needed during weight-bearing.
Surgical options
TPLO (Tibial Plateau Leveling Osteotomy)
TPLO rotates the tibial plateau until the joint is stable during weight-bearing without a functional CCL. It is the most widely performed cruciate repair in the UK, North America, and Australia.
In a retrospective study of 1,000 patients, TPLO carried a 14.8% complication rate (6.6% major, requiring repeat surgery or causing extended lameness), which included 2.8% late meniscal injury and 6.6% infections.
TPLO has a better functional outcome on subjective and objective gait analysis than TTA. At first glance, the analysis of multiple studies allows the hypothesis that TPLO is superior to TTA in terms of long-term clinical outcomes, although further research is needed to confirm this.
Best for: dogs over 20 kg, active dogs, dogs with steep tibial plateau angles.
Cost: $3,000 to $5,000 per stifle at specialist centres.
TTA (Tibial Tuberosity Advancement)
TTA advances the tibial tuberosity to position the patellar tendon perpendicular to the tibial plateau, achieving a similar biomechanical neutralization to TPLO.
Evidence: outcomes comparable to TPLO in most studies; return to function 85 to 93%. Appropriate for medium to large dogs, lower tibial plateau angles, and some anatomic configurations where surgeons prefer TTA.
The first clinical trial showed TTA was associated with less OA progression than TPLO at 6-month follow-up. However, the opposite was reported in the second clinical trial. Strength of evidence is weak neither procedure is clearly superior in OA outcomes.
Best for: dogs over 15 kg; particularly suitable for dogs with lower tibial plateau angles.
Cost: $2,500 to $4,500 per stifle.
Lateral suture / extracapsular repair (LFTS)
Extracapsular stabilization relies on periarticular fibrosis for long-term stability since no artificial suture substitute remains intact in vivo over long periods. A number of extracapsular stabilization techniques have been described and result in normal return to athletic function.
The lateral suture uses a strong monofilament suture to temporarily mimic the CCL while the periarticular fibrous tissue develops. It is lower-cost, technically less demanding, and appropriate for small dogs.
Best for: dogs under 15 to 20 kg; older dogs with lower activity requirements.
CBLO (CORA-Based Leveling Osteotomy)
A newer osteotomy technique that uses individualized CORA-based planning. Outcomes similar to TPLO. For the full CBLO guide, see CBLO surgery in dogs: cost, recovery, and success rate.
Conservative management
Conservative management refers to strict activity restriction, physiotherapy, weight management, and pain medication without surgical stabilization.
For a large, active dog, surgery may be necessary to achieve the best long-term outcome. On the other hand, smaller dogs sometimes fare well with a non-surgical plan, in addition to dogs with medical factors making surgery risky.
Canine rehab will not heal a damaged or torn ligament. Instead, rehab can help by strengthening the surrounding muscles, reducing pain, and addressing compensatory movement patterns.
Conservative management relies on the development of periarticular fibrosis scar tissue that gradually stabilizes the joint over 6 to 12 weeks.
In small dogs (under 15 kg), this fibrosis is often sufficient for acceptable function.
When conservative management is considered:
- Dogs under 10 to 15 kg with partial tears
- Dogs with significant concurrent medical conditions making anesthesia high-risk
- Financial constraints when surgery is not possible
- Older, sedentary dogs with low functional demands
Limitations: OA progresses faster without surgical stabilization. Meniscal tears are more likely. Activity restriction for 8 to 12 weeks is still required.
Surgical vs. conservative: outcome comparison
| Factor | Surgery (TPLO/TTA) | Conservative management |
|---|---|---|
| Return to normal function | 85 to 95% | 20 to 40% (large dogs) |
| OA progression | Slowed | Faster |
| Meniscal tear risk | Managed at surgery | Higher ongoing risk |
| Recovery time | 12 to 16 weeks | 8 to 12 weeks of restriction |
| Cost | $2,500 to $5,000 | $500 to $1,500 ongoing |
| Recommended for large dogs | Yes | No |
| Recommended for small dogs | Often yes | Sometimes acceptable |

For the CBLO alternative, see CBLO surgery in dogs: cost, recovery, and success rate.
Frequently asked questions
Is conservative management ever appropriate for large dogs?
Rarely, and only when anesthesia risk is genuinely prohibitive due to significant cardiac, pulmonary, or metabolic disease.
In such cases, conservative management with physiotherapy and pain management is the best available option not a preferred one. The outcome will generally be poorer than in surgical cases.
Which is better: TPLO or TTA?
Both achieve 85 to 95% good-to-excellent outcomes. TPLO may have a slight edge in objective gait analysis and is more widely performed. TTA may produce less short-term OA progression in some studies.
No clear evidence of long-term superiority exists for either technique. The decision is based on tibial anatomy, dog size, and surgeon preference and experience.
My small dog ruptured its CCL. Do they need surgery?
Not always. Dogs under 10 to 15 kg sometimes achieve acceptable long-term function through conservative management.
However, surgery still produces better outcomes in most small dogs and should be the default recommendation unless there are specific contraindications. Discuss the options with your vet.
How long does recovery take after TPLO or TTA?
8 to 12 weeks of restricted activity with progressive return to full function.
Most dogs walk comfortably by 4 to 6 weeks, bear weight normally by 8 weeks, and return to full activity by 12 to 16 weeks depending on the rehabilitation program.
Will my dog get arthritis even after surgery?
Yes. OA is present in the joint before surgery and will continue to progress after it.
Surgery reduces the rate of OA progression significantly compared to conservative management but cannot reverse existing damage. Long-term management with weight control, exercise, and joint support is important regardless of surgical outcome.

Imaging and Diagnostics Before Referral: What’s Essential and When?
Before referring a patient, ensure you have the right imaging and diagnostics. Learn which tests are essential for accurate veterinary referrals and when to use them
A well-prepared referral saves the specialist time, prevents duplicate testing at the owner's expense, and results in a more productive first consultation.
A poorly prepared referral missing radiographs, incorrect views, or no clinical summary forces the specialist to start from scratch and may delay diagnosis and treatment.
Quick answer: Before orthopedic referral, take minimum two orthogonal radiographic views under sedation, run baseline blood work for any patient likely to need surgery, and write a clear referral summary. CT and MRI are not routinely required before referral; most specialists prefer to perform these in-house to their own protocols.
Key takeaways
- Two orthogonal radiographic views are the minimum for any orthopedic referral: lateral and craniocaudal/mediolateral single views are inadequate
- Sedation improves radiograph quality: precise positioning detects subtle lesions; unsedated films are frequently non-diagnostic
- Send DICOM files, not printed films: digital files allow the specialist to adjust contrast and zoom; printed films are inferior
- CT and MRI are usually performed at the specialist centre: refer before CT/MRI unless the specialist specifically requests pre-referral imaging
- Baseline blood work is essential for any patient expected to need surgical anesthesia: CBC and biochemistry at minimum
- A clear written referral summary with gait findings, lameness duration, and prior treatment adds more value than extra imaging alone
Why pre-referral imaging matters
The most important part of the orthopedic exam and probably the most important part of the workup is attempting to localize the cause of lameness to a single joint or single bone.
Radiographs at the primary care practice serve several purposes: confirming the anatomical location, ruling out differentials, giving the specialist baseline images, and identifying concurrent findings the owner needs to know about.
Poor imaging quality, missing essential baseline tests, and unclear communication with specialists can cause delayed diagnoses and ineffective treatment plans.
Radiography: the essential pre-referral modality
Two orthogonal views minimum
Always take at least two orthogonal views (e.g., lateral and craniocaudal/mediolateral). Use stress or oblique views for joint instability (e.g., CCL rupture, elbow dysplasia). Ensure proper sedation for accurate positioning, especially for pelvic or spinal radiographs.
A single lateral view is not adequate for referral. Fractures, joint mice, and osteophyte patterns require two planes to characterize. Subtle findings visible on one view may be absent on another.
Sedation for positioning: unsedated radiographs in painful patients are often rotated, foreshortened, or underexposed. These films reduce diagnostic value and may force repeat imaging at the specialist centre a cost the owner bears twice. Sedation is appropriate and usually brief for orthopedic positioning.
Specific views by condition
| Suspected condition | Essential views |
|---|---|
| CCL rupture (stifle) | Mediolateral (neutral and flexed), craniocaudal |
| Elbow dysplasia | Mediolateral (neutral and flexed), craniocaudal |
| Hip dysplasia | VD hip-extended, possibly frog-leg lateral |
| Fracture | Lateral and orthogonal view of the entire bone including joints above and below |
| Patellar luxation | Craniocaudal, mediolateral stifle |
| Spinal pain | Lateral and VD of the region, possibly myelogram |
Sending digital files
Send DICOM format where possible. Digital files allow the specialist to adjust window and level settings, zoom into areas of interest, and use measuring tools.
Printed films or JPEG photographs of films are significantly inferior and should be avoided.
When to perform CT before referral
CT is significantly more sensitive than radiography for:
- Medial coronoid process disease (elbow dysplasia)
- Complex periarticular fractures
- Spinal cord compression assessment
- Nasal cavity and dental pathology
Thoracic radiographs provide metastatic and pre-anesthetic screening. No additional radiographs are necessary if the patient will be referred for advanced imaging.
Most specialist centres prefer to perform CT in-house to their own protocols. Referring a patient with CT already done can be counterproductive if the protocol does not meet the specialist's requirements.
Unless the specialist has specifically requested pre-referral CT, radiographs alone are appropriate.
Exception: if CT is readily available at your practice, in good quality, and the specialist has confirmed they will accept your images, pre-referral CT for elbow dysplasia or complex fractures is valuable.
MRI before referral
MRI is superior to CT for soft tissue detail: spinal cord, brain, tendons, and ligaments. It is almost never required before referral.
MRI requires general anesthesia and significant scan time. Specialist centres perform it to their own protocols and prefer to interpret their own studies.
Referring a patient with MRI images from another centre creates interpretation challenges that can slow, not speed, diagnosis.
Laboratory diagnostics
Run basic lab tests (CBC, chemistry, joint fluid analysis if needed) before referring the case.
Pre-referral blood work:
- CBC: detects anaemia, leukocytosis (infection/inflammation), thrombocytopenia
- Biochemistry panel: kidney and liver function essential before any anesthetic
- Relevant for: any patient likely to need surgical anaesthesia at the specialist centre
When joint fluid analysis adds value:
- Suspected immune-mediated polyarthritis
- Joint effusion without clear traumatic or degenerative cause
- Suspected septic arthritis
In chronic orthopedic cases, laboratory diagnostics help differentiate degenerative diseases from immune-mediated or infectious conditions, providing a more complete clinical picture. C-reactive protein levels indicate active inflammation, commonly seen in immune-mediated arthritis. Synovial fluid analysis helps assess infection, immune-mediated polyarthritis, or degenerative joint disease.
The referral summary
A well-written referral letter adds value that no imaging can replace:
Include:
- Signalment and body weight
- Duration and progression of the lameness
- Which limb(s) and which joints on palpation examination
- Gait assessment findings (grade of lameness, pattern)
- Orthopaedic test results (cranial drawer, tibial compression, Ortolani)
- Differential diagnoses considered
- Previous treatments and response
- Reason for referral and what you are asking the specialist to do
Keep it concise. A one-page summary covering the above is far more useful than three pages of unformatted notes.
For the communication framework with the specialist, see how to optimize communication between general practitioners and orthopedic surgeons.
For what happens at the specialist consultation, see what to expect when your patient sees an orthopedic specialist.
For the referral decision criteria, see when to refer for orthopedic surgery: surgical vs non-surgical cases.
Frequently asked questions
Do I need to sedate the dog for pre-referral radiographs?
Yes, for most orthopedic cases. Sedation improves positioning accuracy significantly. Unsedated films in painful patients are frequently rotated or foreshortened and may not provide diagnostic information.
Brief sedation for positioning is appropriate and is standard at most specialist centres for their own imaging.
The specialist centre is far away. Should I try to do a CT first?
Only if the specialist has specifically requested pre-referral CT and you can achieve the required protocol quality. Otherwise, radiographs are sufficient for referral.
CT performed without the specialist's protocol guidance may not meet their imaging requirements and could result in the owner paying for repeat CT at the specialist centre.
What format should I send radiographs in?
DICOM format wherever possible. If DICOM is not available, the highest-resolution uncompressed images you can export.
Avoid photographing films with a mobile phone these are not diagnostically useful and create a poor impression of the case preparation.
Is blood work always required before referral?
Not in an emergency. For elective or semi-urgent referrals where surgical anaesthesia is anticipated, blood work provides essential safety information.
It is best performed at the primary care practice to allow results interpretation by someone who knows the patient's history.
My radiographs show only mild changes. Should I still refer?
Yes, if the clinical signs warrant it. Radiographic severity does not always correlate with clinical severity. A dog with mild radiographic changes but significant lameness affecting quality of life merits specialist assessment.
Conversely, severe radiographic OA in a dog with good function may not need referral urgently.

Physical Therapy & Rehabilitation: How Referring Vets Can Support Recovery
Learn how referring vets can support pet recovery with timely rehab, better communication, and tailored treatment plans
Rehabilitation after orthopedic surgery is not optional it is a core component of recovery.
Dogs that receive structured rehabilitation after procedures such as TPLO, FHO, or fracture repair consistently return to function faster and more completely than those managed with rest alone.
Referring veterinarians are in a key position to set expectations, identify appropriate patients for formal rehabilitation referral, and guide owners through what they can do at home between specialist visits.
Quick answer: Rehabilitation after orthopedic surgery combines passive range-of-motion exercises, controlled leash walking, hydrotherapy, therapeutic laser, and progressive strengthening. Formal rehabilitation with a certified canine rehabilitation practitioner produces measurably better outcomes than rest alone.
Key takeaways
- Rehabilitation significantly improves post-surgical outcomes: dogs receiving post-TPLO rehab return to limb use faster than controls managed with rest alone
- Hydrotherapy is one of the most impactful modalities: water buoyancy reduces weight-bearing stress by up to 90% while building muscle
- Passive range-of-motion exercises begin within the first few days post-surgery to prevent joint stiffness and soft tissue adhesion
- Therapeutic laser can be initiated immediately after surgery to reduce inflammation and support tissue healing
- Rehabilitation referral should be considered for any orthopedic surgical patient, particularly large-breed dogs, bilateral cases, and slow-progressors
- Home exercises taught to owners at discharge sit-to-stands, controlled leash walking, passive ROM extend the benefit of formal sessions
Why rehabilitation matters after orthopedic surgery
Surgery creates a stable repair. Rehabilitation determines the quality of function that is achieved on top of that repair.
Physical rehabilitation is a specialty of veterinary medicine that focuses on strength, mobility, and comfort of pets. Rehabilitation therapy utilizes a combination of therapeutic exercises, physical modalities like laser, and hands-on techniques to alleviate pain and improve function.
Without proper rehabilitation, dogs may experience prolonged pain, stiffness, muscle atrophy, or even a decline in overall function. Physical therapy helps bridge the gap between surgery and a full return to normal activities by promoting safe and effective healing.
The referring vet's role after orthopedic surgery is threefold: enforce rest during early healing, manage pain so the dog can engage in rehab exercises, and identify patients who need formal rehabilitation referral.
Rehabilitation modalities
Passive range-of-motion exercises (PROM)
Range-of-motion and stretching exercises are vital activities to help improve joint motion and flexibility in pets after surgery. These exercises help prevent adhesions between soft tissues and bone, improve muscle extensibility, and prevent further injury to joints, ligaments, tendons, and muscles.
PROM begins within the first few days of surgery, before the dog can actively bear weight. Owners are typically taught how to perform these at discharge.
The technique involves gentle flexion and extension of the affected joint through its comfortable range, without forcing the endpoint.
Hydrotherapy (underwater treadmill)
The buoyancy effect reduces weight-bearing stress by up to 90%, allowing pets to exercise with minimal pain while still building muscle mass.
Most veterinarians recommend beginning hydrotherapy only after the surgical site is fully closed and inflammation has subsided, which usually occurs after two to four weeks but this timeline varies depending on the procedure and the individual pet.
The underwater treadmill is the most commonly used hydrotherapy tool in veterinary rehabilitation. Pool swimming is also used but provides less controlled, task-specific exercise.
Therapeutic laser (photobiomodulation)
Laser therapy can be initiated right after surgery to stimulate healing.
Therapeutic laser reduces inflammation, decreases pain, and promotes tissue repair at the cellular level. It is one of the few modalities that can begin immediately post-operatively at the surgical site.
Therapeutic exercises
Physiotherapy exercises for dogs can include things like balancing on three legs, walking on the front legs, sit-and-stand exercises, and side-hopping. These exercises can help with recovery.
Progressive land-based exercises are introduced as healing advances. Sit-to-stand exercises build hindlimb strength without high-impact loading. Balance boards, cavaletti poles, and incline walking are added as the dog progresses.
Heat and cold therapy
Cold therapy (cryotherapy) is used in the first 48 to 72 hours post-surgery to reduce inflammation and swelling. Heat is introduced later to relax muscles and increase local circulation before exercise sessions.
When to refer to a certified rehabilitation practitioner
Formal rehabilitation referral is appropriate for:
- Large and giant breed dogs after major orthopedic procedures (TPLO, THR, fracture repair)
- Any dog that is not bearing weight on the operated limb by the expected timepoint
- Bilateral cases where both limbs are affected
- Dogs with concurrent neurological signs
- Dogs with pre-existing muscle atrophy or poor baseline condition
- Cases where owners cannot reliably perform home exercises
A certified canine rehabilitation practitioner (CCRP) or diplomate of the American College of Veterinary Sports Medicine and Rehabilitation (DACVSMR) provides the most structured and evidence-based program.
Home exercises for owners
Most owners can learn and perform the following between formal sessions:
Short controlled leash walks: beginning as short as 5 minutes, three times daily, increasing progressively per the surgeon's protocol. No pulling, no running.
Passive range-of-motion: gentle flexion and extension of the surgical joint, 10 to 15 repetitions, two to three times daily. Stop at the point of resistance; never force.
Sit-to-stand exercises: asking the dog to sit and stand repeatedly encourages hindlimb muscle activation. Begin with 5 repetitions and increase over weeks.
Cold packing: 10 to 15 minutes of cold application to the surgical site after exercise sessions in the first two weeks reduces local inflammation.
For the pain management that supports engagement in rehabilitation, see orthopedic pain management in pets: multimodal approaches. For the nutrition and supplement context, see nutrition and supplements for orthopedic patients.
Frequently asked questions
How soon after orthopedic surgery can rehabilitation begin?
Passive range-of-motion and short controlled leash walks typically begin within the first few days. Hydrotherapy begins once the incision is closed and inflammation has subsided, usually at two to four weeks.
Therapeutic laser can begin immediately. The surgeon's discharge protocol sets the specific timeline for each patient.
My patient is not bearing weight at two weeks post-TPLO. Should I refer?
Yes. Persistent non-weight-bearing at two weeks warrants assessment either by the performing surgeon or a rehabilitation specialist. Causes include inadequate pain management, implant-related issues, or lack of physiotherapy engagement.
Formal rehabilitation evaluation is appropriate here.
Can owners do rehabilitation at home without formal sessions?
Home exercises taught at discharge are valuable and can significantly improve outcomes. However, formal sessions with a certified practitioner provide progression, monitoring, and modalities (laser, underwater treadmill) that owners cannot replicate.
Where resources allow, a combination is ideal.
What does a typical post-TPLO rehabilitation program look like?
Week 1 to 2: PROM, cold therapy, very short leash walks. Week 3 to 4: progressive leash walk duration, sit-to-stand exercises, hydrotherapy begins.
Week 5 to 8: increased land exercises, balance work, progressive incline walking. Month 3 to 4: gradual return to normal activity. Specific protocols vary by surgeon and practitioner.
Is rehabilitation covered by pet insurance?
Some comprehensive pet insurance plans cover rehabilitation therapy following surgery. Coverage varies significantly by policy and provider. Owners should check their policy before assuming coverage.

TPLO, CBLO, and TTA: A Guide to Cruciate Surgery Options
Compare TPLO, TTA, and CBLO surgeries for dog cruciate ligament injuries. Learn differences, costs, recovery, and best option for your dog
When a dog tears its cranial cruciate ligament (CCL), three osteotomy-based surgeries are currently in widespread use: TPLO (tibial plateau leveling osteotomy), TTA (tibial tuberosity advancement), and CBLO (CORA-based leveling osteotomy).
All three aim to change the biomechanics of the stifle to eliminate the need for the damaged CCL.
They differ in the specific bone cut, the mechanism of stabilization, the implants used, and the evidence base supporting their outcomes.
Quick answer: TPLO, TTA, and CBLO all stabilize the stifle by changing tibial geometry. TPLO has the most evidence, is the ACVS gold standard for large dogs, and achieves 93% limb function at 1 year. TTA produces similar long-term outcomes. CBLO is used mainly for immature dogs and revision surgery.
Key takeaways
- TPLO is the most evidence-supported procedure: a 2013 study confirmed 93% limb function restoration at 1 year; it is the ACVS-preferred procedure for most large, active dogs
- TTA produces similar long-term outcomes to TPLO: a PMC systematic review of 72 studies found both are successful; TTA may have slightly faster early recovery
- CBLO is a newer TPLO variant: the osteotomy is made at the CORA rather than proximally; fewer long-term studies exist; mainly used for immature dogs and revision cases
- All three require 8 to 12 weeks of activity restriction: post-operative management is essentially identical; radiographic healing confirmation before activity return is required for all
- TPLO has a lower SSI rate than TTA per the PMC systematic review; this is clinically meaningful given TPLO's already-elevated SSI risk vs other orthopedic procedures
- The choice between TPLO and TTA is often surgeon preference and facility capability: no clear clinical superiority exists for appropriately selected patients; CBLO is less universally available
How each surgery works
TPLO: tibial plateau leveling osteotomy
TPLO makes a curved osteotomy through the proximal tibia and rotates the tibial plateau segment to approximately 5 degrees.
This rotation eliminates the cranial shear force that drives tibial thrust when the CCL is absent. A plate and locking screws hold the rotated segment while the osteotomy heals.
The result: the stifle is mechanically stable during weight bearing regardless of CCL integrity, because the geometry of the tibial plateau no longer creates the shear force that was causing instability.
TTA: tibial tuberosity advancement
TTA moves the tibial tuberosity (the bony prominence at the front of the tibia where the patellar tendon attaches) forward, changing the angle between the patellar tendon and the tibial plateau.
When this angle reaches approximately 90 degrees, the patellar tendon acts as an active stabilizer of the stifle during weight bearing, neutralizing the cranial shear force.
TTA uses a cage (typically titanium or porous polyethylene) to maintain the advanced position of the tuberosity during healing.
B Braun Vet Care confirms: TTA was quicker with a smaller incision; patients weight bore faster with fewer direct post-operative complications. However, longer-term studies show similar outcomes for each procedure.
CBLO: CORA-based leveling osteotomy
CBLO is a variant of the leveling osteotomy concept.
TPLO makes its circular cut proximally near the tibial plateau. CBLO makes its osteotomy at the CORA (center of rotation of angulation), which is lower on the bone.
The goal is to correct the tibial deformity at the site where it actually originates geometrically, which may produce a more anatomically accurate correction in some dogs.
Southern Animal Health confirms: CBLO benefits appear limited to immature dogs or revision surgery where cuts have already been made higher on the bone.
Outcome comparison
TPLO outcomes
A 2013 study comparing TPLO and TTA found TPLO patients achieved 93% restoration of limb function at 1 year.
A randomized blinded clinical trial comparing lateral fabellar suture stabilization with TPLO in 80 dogs confirmed TPLO produced higher peak vertical force and higher owner satisfaction at 1 year.
TPLO has the most extensive published evidence base of any cruciate repair technique in dogs.
Vetamac confirms: a 2013 study found TPLO patients averaged 93% limb function return at 1 year, and a higher percentage achieved full return compared to TTA.
TTA outcomes
The PMC systematic review of 72 studies (PMC9748159) found both TPLO and TTA are successful management options, with no lameness at long-term evaluation for most patients.
It also found TTA showed better OA scores up to 6 months postoperatively, while TPLO had lower SSI rates.
B Braun Vet Care confirms: many longer-term studies show similar outcomes for TPLO and TTA; one study suggests TPLO had a marginally better outcome than MMP.
Southern Animal Health confirms: a study of long-term results 3 years after surgery clearly shows that TTA and MMP candidates show more arthritis and more discomfort than dogs repaired with TPLO.
CBLO outcomes
CBLO has fewer published long-term studies than TPLO or TTA. Early results are promising.
The SustainableVet.org CBLO article confirms that CBLO produces good outcomes and is particularly used for dogs with steep tibial slopes or early arthritis.
Longer-term comparative data against TPLO in equivalent patient populations remains limited.
Patient selection
When TPLO is the preferred choice
- Dogs over 35 to 40 pounds (medium to large breeds)
- Young, athletic, or working dogs of any size
- Dogs with steep tibial plateau angles (TPA above 25 to 30 degrees)
- Cases where maximum long-term joint stability and arthritis control are priorities
When TTA may be considered
- Dogs with low to moderate TPA (the mechanical advantage of TTA is greatest when the existing TPA is near 90 degrees)
- Cases where a shorter surgical time is beneficial (older dogs with anesthetic risk)
- Some surgeons prefer TTA for dogs with high-velocity tibial thrust where TTA's mechanism may provide faster active stabilization
When CBLO may be considered
- Skeletally immature dogs where TPLO would cut across the growth plate
- Revision cases where a proximal osteotomy has already been performed
- Dogs with unusual tibial geometry where the CORA is positioned lower than average
SustainableVet.org confirms: CBLO is a newer, flexible option that fits many situations, especially for dogs with steep tibial slopes or early arthritis.
Recovery comparison
All three procedures require essentially the same post-operative management:
- Strict activity restriction for 8 to 12 weeks
- Leash walks only during the restriction period
- Radiographic assessment of bone healing at 6 to 8 weeks and 12 weeks
- Progressive return to activity after radiographic confirmation
The one consistent early difference: TTA dogs may weight bear more readily in the first 1 to 2 weeks.
B Braun Vet Care confirms: TTA patients were quick to weight bear with fewer direct post-operative complications compared to TPLO.
This early advantage does not produce meaningfully different long-term outcomes in most studies.
Cost comparison
All three osteotomy procedures are similarly priced at referral centers -- typically $3,000 to $6,000 per stifle. The specific cost depends on the facility, surgeon, dog size, and geographic region.
Cost differences between TPLO, TTA, and CBLO at the same facility are typically not substantial.
For the full TPLO overview, see TPLO surgery pros and cons for dogs. For CBLO specifically, see CBLO surgery in dogs. For alternatives, see alternatives to TPLO surgery for dogs.
For lateral suture comparison, see lateral suture vs TPLO for dogs.
Frequently asked questions
Is TPLO better than TTA?
For most large, active dogs, the balance of evidence slightly favors TPLO for long-term outcomes and lower arthritis progression.
However, multiple studies show no significant difference in objective gait analysis at long-term follow-up. The choice is often surgeon experience and facility capability rather than an absolute clinical superiority.
What is CBLO and is it better than TPLO?
CBLO is a variant of the leveling osteotomy that makes its bone cut at a different anatomical location. It is not established as better than TPLO for routine adult dog CCL repair.
Its main current applications are in immature dogs and revision surgery cases where TPLO would be anatomically difficult.
Which surgery has the lowest complication rate?
TTA generally has a lower SSI rate in some studies and was associated with fewer immediate post-operative complications in others.
However, TPLO and TTA have broadly comparable overall complication profiles at experienced facilities. CBLO data is more limited.
Can my regular vet perform any of these surgeries?
TPLO and TTA require specialized training and equipment (oscillating saw, specific implants, fluoroscopy for osteotomy confirmation). Both are typically performed by board-certified surgeons or general practitioners with specific TPLO or TTA training.
CBLO is similarly specialized. None of these are routine general practice procedures.
My dog had a failed TTA. Can TPLO be done as a revision?
Yes -- TPLO can be performed as a revision after a failed TTA in appropriate cases. The surgical planning differs from primary TPLO because the proximal tibial anatomy has already been altered.
CBLO may be used in these cases for similar reasons. This is a specialist procedure requiring careful pre-operative radiographic planning.
