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.

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.

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."

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.

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.

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:

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):

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

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:

1. Culture before every systemic course: never empirically re-prescribe after MRSP has been identified
2. Topical therapy to reduce systemic antibiotic reliance: topical treatment alone resolved 65.4% of MRSP pyoderma cases in published research (PMC4204846)
3. Treat only clinical infection, not carrier status: systemic antibiotics are not indicated for colonized dogs without clinical signs
4. Complete the full course: incomplete courses select for resistance subpopulations
5. Address the underlying disease: unmanaged atopy or endocrine disease drives perpetual antibiotic cycles
6. 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

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.

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.

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."

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.
