Recognize and Manage Post-Surgical Complications in Referred Patients

Learn how to recognize and manage common post-surgical complications in referred pets with clear steps for follow-up, treatment, and communication

Sustainable Vet Group

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.

Nutrition & Supplements for Orthopedic Patients: What Works and What Doesn’t

Discover which pet supplements truly support joint health, and what to avoid in orthopedic care. Vet-backed tips for better recovery and mobility

Sustainable Vet Group

Why Nutrition Matters in Orthopedic Recovery

Nutrition plays a key role in how well a dog recovers after orthopedic surgery or injury. Bones, joints, muscles, and soft tissues all need the right nutrients to heal properly. Without enough protein, vitamins, and minerals, healing slows down and the risk of complications goes up.

Inflammation is common after surgery. Some foods can help reduce it naturally, like those rich in omega-3 fatty acids. At the same time, proper nutrition supports tissue repair, keeps muscles strong, and helps rebuild cartilage around joints.

Supplements can help, but they don’t replace a balanced diet. For example, giving glucosamine is useful, but it won’t work if the dog is eating low-quality food that lacks protein or key vitamins. Recovery works best when supplements are part of a complete nutrition plan, not the only solution.

Start with the Basics: Weight and Diet First

Importance of Weight Management

Keeping a healthy weight is one of the most important parts of orthopedic care. Extra weight puts more stress on joints, especially the knees, hips, and spine. For dogs recovering from surgery, even a few extra pounds can slow healing and increase pain.

Obesity is strongly linked to many joint problems, including arthritis, cruciate ligament injuries, and hip dysplasia. The more weight a dog carries, the harder the joints must work, leading to faster wear and tear. In overweight dogs, surgeries like TPLO or joint replacement often have slower and more difficult recoveries.

Helping a dog reach or stay at a healthy weight reduces this stress and improves mobility. It also lowers inflammation, which supports healing. Even small weight loss—just 5–10% of body weight—can make a big difference in how a dog moves and feels after orthopedic treatment.

Key Nutrients in an Orthopedic Diet

A strong orthopedic recovery starts with a diet that supports healing tissues. Protein is the most important building block—it helps repair muscles, tendons, and bones. Dogs healing from surgery need more protein than usual, especially during the first few weeks post-op.

Calcium and phosphorus are key for bone strength. They must be given in the right ratio, especially in growing dogs, to avoid bone problems. Vitamins like C and D support collagen repair and calcium absorption. Omega-3 fatty acids from fish oil can reduce inflammation in joints and help with pain.

But more isn’t always better. Over-supplementing can throw off balance. For example, too much calcium can lead to bone disorders. It’s best to provide these nutrients through a balanced, high-quality orthopedic or joint-support formula unless your vet recommends extra supplements. Good food is the foundation; supplements should fill gaps, not replace meals.

Supplements That Work: Backed by Veterinary Use

When used with the right diet and weight control, certain supplements can support healing and reduce joint pain. Here are some of the most commonly used and well-researched options in veterinary orthopedic care.

1. Omega-3 Fatty Acids (Fish Oil)

Omega-3 fatty acids, especially EPA and DHA from fish oil, are powerful anti-inflammatory agents. They help reduce joint swelling and improve mobility in dogs with arthritis or post-surgery stiffness. Studies show they can lower the need for pain medications over time.

Common sources include salmon oil, sardine oil, and anchovy oil. Veterinary-grade products are more purified and properly dosed compared to grocery store options. The usual dose is based on body weight, and your vet can guide you to avoid over-supplementation. Fish oil is often the first supplement added to a recovery plan because of its safety, long-term benefits, and ability to work well with other treatments.

2. Green-Lipped Mussel (GLM)

Green-lipped mussel is a natural anti-inflammatory that comes from shellfish native to New Zealand. It contains omega-3s, amino acids, and antioxidants that work together to ease joint pain and stiffness, especially in dogs with osteoarthritis.

GLM is often found in vet-recommended joint products and is considered safe for long-term use. Research shows it can improve comfort and mobility in both older dogs and those recovering from orthopedic surgery.

Unlike synthetic drugs, GLM has fewer side effects and provides a gentle way to support joint health. It's not a cure, but when used consistently, it may lower the need for pain meds and improve quality of life over time.

3. Glucosamine and Chondroitin

Glucosamine and chondroitin are among the most widely studied supplements for joint care in dogs. They support cartilage health, reduce inflammation, and may slow the breakdown of joint tissues. Many vets include them in post-op recovery plans or for long-term management of arthritis.

However, results vary. Some dogs show clear improvement in stiffness and mobility, while others don’t respond as well. The biggest benefits are seen with consistent use over at least 6–8 weeks.

These compounds work best in early to moderate joint disease, not as much in advanced cases. While not a magic fix, they’re still a go-to part of many joint support protocols because of their long safety history.

4. MSM (Methylsulfonylmethane)

MSM is a sulfur-based compound found in plants and animals. In orthopedic patients, it's used for its anti-inflammatory and pain-relieving effects. MSM helps reduce joint swelling and may ease muscle soreness, which is useful after surgery or injury.

This supplement is often paired with glucosamine and chondroitin for added support. It also plays a role in building healthy collagen and connective tissue, which are key during the healing phase. MSM is generally well-tolerated and safe for long-term use.

While more research is still needed, many veterinarians recommend it as part of a combined joint supplement, especially when managing pain without heavy use of NSAIDs.

5. UC-II (Undenatured Collagen Type II)

UC-II is a unique form of collagen that works differently from other joint supplements. It targets the immune system and helps reduce the inflammation that causes cartilage breakdown. Instead of adding building blocks like glucosamine, UC-II trains the immune system to stop attacking joint tissues.

This can be especially helpful in dogs with immune-driven joint problems or chronic arthritis. Some studies suggest it may work better than glucosamine in certain cases, especially for dogs who haven’t responded well to standard supplements.

UC-II is usually taken in small doses and is often combined with other anti-inflammatory agents. It's a good option for dogs needing extra immune-based joint care.

6. Avocado/Soybean Unsaponifiables (ASUs)

ASUs are a mix of natural plant extracts made from avocados and soybeans. They work by slowing cartilage breakdown and blocking enzymes that damage joint tissue. Though not as common as other supplements, ASUs have shown promising results in both human and veterinary studies.

They’re often included in high-quality veterinary joint products along with glucosamine or chondroitin. ASUs are best used when the goal is to protect cartilage and delay further joint damage.

They may also reduce pain and improve mobility in long-term joint conditions. While not a first-line supplement, they offer extra support for dogs with ongoing joint stress or after major orthopedic surgery.

Natural Options Gaining Interest

Alongside traditional supplements, some natural compounds are gaining attention for their potential to support joint health. While the research is still developing, these options may offer gentle support when used carefully and under veterinary guidance.

1. Turmeric (Curcumin)

Turmeric contains curcumin, a natural compound known for its anti-inflammatory effects. Some studies and reports suggest it may help with joint pain and stiffness in dogs, especially those with arthritis. However, curcumin has poor absorption in the body unless combined with other ingredients like black pepper extract.

Many pet supplements use enhanced formulas to improve effectiveness. While it’s a promising option, the results are mixed and more research is needed. Still, turmeric can be a helpful addition to a complete joint care plan when properly formulated.

2. Microlactin

Microlactin is a dried milk protein from cows, known for its anti-inflammatory properties. It works by blocking white blood cells that contribute to joint inflammation and tissue damage. While it's newer compared to other joint supplements, early research and some clinical use suggest it may help reduce pain and improve mobility in dogs with chronic joint issues.

It’s often used as a secondary supplement for dogs who don’t fully respond to traditional options. So far, it appears safe and well-tolerated, but long-term studies are still limited.

3. CBD Oil for Joint Pain

CBD oil has gained popularity for managing pain and anxiety in pets, including dogs with joint problems. Some owners report better mobility and reduced stiffness. Early research also supports its potential anti-inflammatory and pain-relieving effects. However, there are concerns around safety, correct dosing, and product quality.

Veterinary-approved CBD products are best, and you should always speak with your vet before starting. While it shows promise, CBD should never replace proven treatments and should only be used as part of a supervised care plan.

4. Vitamins C & E for Joint Health

Vitamins C and E are antioxidants that help protect joints from damage caused by free radicals. They don’t rebuild cartilage or stop inflammation directly, but they support overall tissue health. In orthopedic recovery, these vitamins may help reduce oxidative stress around healing joints.

Most dogs get enough of these nutrients from balanced diets, so extra supplementation is usually not needed unless advised by a vet. When used, they serve more as add-ons rather than core treatments for joint disease or post-surgery care.

What Often Doesn’t Work (or Needs Caution)

Not all joint supplements are effective—or safe—when used without proper guidance. Many products on the market make big claims but offer little real benefit, especially when not chosen carefully.

Here are common mistakes to avoid:

  • Generic or low-quality supplements: Many over-the-counter joint products lack proper testing or use low-grade ingredients. They may contain less active compound than listed or have poor absorption, making them ineffective.
  • Overuse of single-ingredient products: Giving high doses of one supplement, like calcium or glucosamine, without balancing it with other nutrients can cause more harm than good. It may lead to imbalances or worsen certain conditions.
  • Delaying supportive care: Waiting until a dog is in severe pain or has lost mobility can limit how well supplements and nutrition work. Early support gives the best long-term results.

Supplements are most helpful when started early, chosen with care, and combined with a full recovery plan. Always consult your vet before starting anything new—what works for one dog may not suit another.

How to Choose the Right Supplements

Choosing the right joint supplements for orthopedic care isn’t just about picking a popular brand. The quality, dosage, and how the supplement works with your dog’s overall plan all matter.

Here’s what to focus on:

  • Vet-recommended or clinically tested brands: Look for supplements that have veterinary backing or are used in clinical studies. These are more likely to be safe, effective, and properly dosed.
  • Absorption and dosage form: Some supplements work better in liquid or chew form because they’re easier to absorb. Powder-filled capsules may not break down well, especially in sick or older dogs.
  • Purity and quality control: Choose products made by trusted companies that test for contaminants like heavy metals or fillers. Avoid supplements without clear labels or dosage guidelines.
  • Part of a full plan: Supplements work best when used alongside proper diet, weight management, and physical therapy. They are not magic cures on their own.

Talk to your vet to make sure the supplement fits your dog’s condition and recovery stage. Personalized support is always better than one-size-fits-all.

When to Start and How to Monitor Progress

Starting nutritional support and supplements early in the recovery process gives the best chance for healing. The goal is to reduce inflammation, protect joints, and support tissue repair before damage becomes severe. In many cases, waiting too long can limit how well these therapies work.

Early intervention helps to:

  • Reduce swelling and stiffness after surgery
  • Support faster healing of bones and soft tissues
  • Delay or prevent long-term joint damage

Once supplements are started, it’s important to track your dog’s progress over several weeks.

Watch for signs of improvement like:

  • Better mobility or ease in getting up
  • Less limping or stiffness after rest
  • Reduced need for pain medication

Keep a simple journal or video log to track changes. If there’s no clear improvement after 6–8 weeks, or if your dog gets worse, it’s time to re-evaluate the plan. Your vet may recommend changing the supplement, adjusting the dose, or focusing more on diet and physical therapy.

Every dog is different—regular check-ins help keep the recovery on track.

Always Work With Your Veterinarian

Supplements and nutrition can play a big role in orthopedic recovery, but they should never be used without your veterinarian’s guidance. Every dog is different. Age, breed, diagnosis, weight, and other health issues all affect which supplements are safe and effective.

Your vet can build a personalized plan that fits your dog’s specific needs. For example, a dog recovering from TPLO surgery may need different support than one with chronic arthritis or hip dysplasia. Vets also help choose the right product, dosage, and timing for each stage of recovery.

Monitoring is just as important. Some supplements can interact with medications or cause mild side effects like stomach upset. Your vet can spot these early and make changes if needed.

Veterinarians also work closely with rehab professionals. Together, they balance nutrition, medication, and physical therapy to support healing. This team approach helps avoid delays, reduces pain, and improves long-term joint health.

In short, the best results come when supplements are used as part of a full veterinary-guided plan—not in place of one. Always keep your vet in the loop.

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

Sustainable Vet Group

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.

Orthopedic Pain Management in Pets: Multimodal Approaches

Learn how multimodal pain management improves recovery in pets after orthopedic surgery using meds, rehab, and at-home care

Sustainable Vet Group

Pain management after orthopedic surgery is not a single drug it is a strategy.

Orthopedic pain involves multiple pathways: peripheral inflammation at the surgical site, spinal sensitization, and ongoing nociceptive signals from healing tissue. Addressing all of these requires more than one type of medication.

 

Quick answer: Multimodal analgesia combines NSAIDs, opioids, gabapentin, local anesthetic blocks, and non-drug therapies such as cryotherapy and laser. Using multiple agents at lower doses reduces side effects while achieving better pain control than any single drug at high dose.

 

Key takeaways

  • NSAIDs are the cornerstone of post-orthopedic pain management; they target peripheral inflammation and are the most consistently effective class
  • Multimodal analgesia outperforms monotherapy: a 2026 study found local anesthetics combined with opioid and NSAID provided the best pain control
  • Preemptive analgesia before surgery reduces central sensitization and lowers post-op pain scores and total drug requirements
  • Gabapentin is most useful for nerve-mediated and chronic pain; evidence for acute orthopedic pain alone is limited
  • Tramadol has poor evidence: studies found no clinical benefit for OA pain; it is no longer a recommended primary analgesic
  • Non-drug modalities (cold therapy, laser, rehab) are additive to pharmacological control and reduce total drug burden

Why single-drug pain management falls short

Orthopedic pain in dogs is not a single signal from a single location. It involves:

  • Peripheral sensitization: inflammatory mediators (prostaglandins, cytokines) at the surgical site lower the pain threshold locally
  • Central sensitization: repeated pain signals cause "wind-up" in the spinal cord, amplifying the pain response
  • Nociceptive pain: from tissue damage, implants, and ongoing healing
  • Neuropathic components: nerve stretch or compression, particularly in fracture repairs and spinal-adjacent procedures

Managing this pain with a single drug, like an NSAID alone, is often not enough to keep pets comfortable. A multimodal approach uses a combination of medications and therapies that work on different parts of the pain pathway.

The pharmacological components

NSAIDs

NSAIDs are the cornerstone of pain management in OA patients who can take them safely. NSAIDs provide anti-inflammatory and pain-relieving effects that target affected joints, helping restore function.

Common veterinary NSAIDs: meloxicam, carprofen, robenacoxib, grapiprant. All require baseline blood work (kidney and liver function) before use and monitoring during long-term administration.

NSAIDs should not be combined with corticosteroids or with each other. A washout period of 5 to 7 days is required when switching between NSAIDs.

Preemptive analgesia

Giving pain medications before surgery reduces central sensitization, or "wind-up" pain, which makes pain harder to treat later. It leads to smoother recovery, lower drug needs post-op, and better comfort for pets during and after orthopedic procedures.

Pre-operative NSAID administration, opioid premedication, and local anesthetic blocks administered before surgical incision all reduce the total pain burden the patient experiences.

Opioids

Combinations: NSAIDs and opioids can be used together for enhanced analgesia.

Opioids (methadone, buprenorphine, hydromorphone) are used perioperatively and in the immediate post-operative period for moderate-to-severe pain. They act centrally, complementing the peripheral action of NSAIDs.

Multimodal analgesia combining local anesthetics, hydromorphone, and meloxicam provided the best pain control in small-breed dogs after orthopedic surgery across a retrospective analysis of 205 dogs.

Gabapentin

Gabapentin is sometimes used as an adjunct pain medication; its best application may be for neuropathic pain.

Gabapentin (brand names: Neurontin, Aclonium) is one of several medications used to complement NSAIDs in multimodal plans.

Gabapentin is also useful for managing the restlessness and anxiety that can accompany post-surgical pain and confinement. Its sedative properties can support rest during the critical early recovery window.

Local anesthetic blocks

Locoregional anesthesia (epidural, nerve blocks, intra-articular injection) provides targeted pain control at the surgical site. Local blocks are effective for acute pain.

For chronic pain, periodic local blocks may be considered if appropriate.

Loco-regional blocks reduce the amount of systemic opioid required and can provide hours of post-operative analgesia.

Amantadine

Amantadine is one of several medications used to complement NSAIDs in multimodal therapy plans for canine OA.

Amantadine is an NMDA receptor antagonist that reduces central sensitization.

It is particularly useful in chronic pain cases where "wind-up" is established, and in patients whose NSAIDs are not providing adequate relief alone.

Monoclonal antibodies (bedinvetmab / Librela)

Bedinvetmab (Librela) is a new option, now available in many countries. It is given as a once-a-month injection. It binds to nerve growth factor (NGF), disrupting pain signal transmission and decreasing inflammation. This medication is shown to be effective with minimal side effects.

This class represents a new approach for long-term OA pain management following orthopedic surgery.

Tramadol not recommended

Studies have shown tramadol to be ineffective in treating OA. In one study, treatment with tramadol provided no clinical benefit for dogs with OA of the elbow or stifle joint.

Tramadol's use in canine analgesia has significantly declined following clinical trial evidence showing poor efficacy. It is no longer a recommended primary analgesic for orthopedic pain in dogs.

Non-pharmacological components

Non-drug therapies include cold and heat therapy, physical rehabilitation, hydrotherapy, acupuncture, laser therapy, and massage.

Cryotherapy (cold therapy): applied for 10 to 15 minutes to the surgical site in the first 48 to 72 hours. Reduces local inflammation and provides analgesia through nerve conduction slowing.

Therapeutic laser: reduces inflammation and promotes tissue healing. Can be initiated immediately after surgery at the incision site.

Rehabilitation exercises: passive range-of-motion, controlled walking, and progressive strengthening reduce pain through improved joint mechanics and muscle support.

Acupuncture: some evidence for adjunct pain relief in OA; most useful as part of a comprehensive multimodal plan.

Frequently asked questions

What is multimodal analgesia in dogs?

Multimodal analgesia uses two or more drugs or therapies that target different parts of the pain pathway simultaneously.

The aim is better pain control at lower doses of each individual agent, which reduces side effects while improving efficacy.

It is the current standard of care for orthopedic pain management in veterinary medicine.

Can I give my dog human pain relievers like ibuprofen after orthopedic surgery?

Never. Ibuprofen and acetaminophen are toxic to dogs. Even a single dose can cause gastrointestinal hemorrhage, kidney failure, or liver failure.

Only use pain medications specifically prescribed by your veterinarian for your dog.

How long will my dog need pain medication after orthopedic surgery?

Acute pain management (opioids, high-dose NSAIDs) typically lasts 5 to 14 days post-surgery. Ongoing NSAID therapy for OA management may continue for months or long-term depending on the joint and the procedure.

Your vet will reassess at each recheck appointment.

My dog seems painful even with medication. What should I do?

Contact your vet. Pain that breaks through prescribed medication means the current protocol is insufficient.

A medication adjustment, a dose increase within safe limits, or the addition of another agent (gabapentin, amantadine) may be needed. Do not increase NSAID doses without veterinary guidance.

Is gabapentin effective for post-surgical orthopedic pain in dogs?

Gabapentin's evidence for acute orthopedic pain is limited. Its most established role is in neuropathic and chronic pain.

In the post-surgical context it is most useful for managing restlessness, anxiety, and sleep disruption, and for cases with a neuropathic component.

It is usually prescribed as an adjunct, not a primary analgesic.

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

Sustainable Vet Group

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.

External Fixators and Internal Plating: When Are These Indicated?

When do dogs need external fixators vs. internal plating? Learn key indications, pros, and real case examples in veterinary fracture repair

Sustainable Vet Group

When a dog breaks a bone, the surgical goal is to stabilize the fracture so it heals correctly. Two of the most common methods are external skeletal fixation and internal plate fixation.

Choosing between them depends on the fracture type, location, the dog's size and health, and the presence of any concurrent wounds or infection.

 

Quick answer: External fixators use pins through the skin connected to an external frame; internal plates fix directly to bone. External fixators suit open fractures and contaminated bone. Internal plating is preferred for most closed fractures and needs less daily home care.

 

Key takeaways

  • External fixators use pins through the skin connected to external bars; preferred for open fractures and when internal implants would increase infection risk
  • Internal plating fixes a plate directly to bone under the skin; it provides rigid fixation for most closed long-bone fractures
  • Fracture type is the primary determinant: open or contaminated fractures favour external fixation; simple closed fractures favour internal plating
  • External fixators need daily pin-site cleaning to prevent tract infections, the most common complication
  • Internal plating is generally superior for most closed fractures; no direct head-to-head studies exist for all configurations
  • Both methods can be combined (hybrid fixation) for complex fractures requiring biological and mechanical advantages

External skeletal fixation (ESF)

What it is

External fixation is completed using a device called an external fixator. This specialized device consists of multiple pins and external bars or rings, which hold a fractured bone in place during the healing process.

Pins are placed through the skin and bone on either side of the fracture. These pins connect to an external frame bars in linear fixators, rings in circular (Ilizarov-type) fixators.

The frame holds the fracture in alignment without directly contacting the fracture site.

Types

Type I (uniplanar, unilateral): pins exit one side of the limb only; the simplest and most commonly used type.

Type II (biplanar, bilateral): pins exit both sides of the limb; more rigid than Type I.

Circular fixators: ring-based frames that allow gradual correction of complex deformities and angular limb corrections. More technically demanding.

When external fixation is indicated

External fixation is an effective procedure to correct complex fractures and angular limb deformities in dogs.

Key indications:

  • Open fractures with skin wounds communicating with the fracture site placing internal implants risks trapping contamination
  • Infected or contaminated bone external fixation avoids implant-associated biofilm infection
  • Soft tissue compromise severe bruising, degloving, or burn injury around the fracture
  • Angular limb deformities gradual correction is possible with circular fixators
  • Skeletally immature dogs where growth plates need to be protected
  • Temporary stabilization before definitive repair (damage control orthopaedics)

Limitations and home care

External fixators require daily pin-site care by the owner cleaning around each pin to prevent tract infection. Pin-tract infection is the most common complication and can require early removal if severe.

The external frame can be bulky and requires the dog to avoid catching it on furniture or other dogs.

Internal plate fixation

What it is

Internal plating fixes a metal plate directly to the bone surface using cortical screws. The plate bridges the fracture and holds the bone in alignment during healing.

Everything is under the skin; no external components are visible once the wound is closed.

In all but the most minor fractures, internal fixation is superior to external fixation. Typically implants are made from inert metals such as stainless steel and take the forms of pins, plates, screws, or wires.

When internal plating is indicated

The advantages of addressing long bone fractures with internal fixation versus external coaptation include early return to function and maintenance of joint motion. Internal fixation is indicated for fractures that are subjected to compression, shearing, and/or tensile forces.

Key indications:

  • Closed long-bone fractures in medium and large breeds radius/ulna, femur, tibia, humerus
  • Articular fractures where precise anatomical reduction is essential
  • Highly comminuted closed fractures where external fixation cannot achieve adequate stability
  • Periprosthetic fractures around existing implants
  • Fractures requiring early weight bearing plates provide more rigid fixation than most external frames

Plate types

Locking plates (LCP): the most commonly used system in modern veterinary orthopaedics. Screws lock into the plate, creating an angular-stable construct that does not rely on friction between the plate and bone.

Conventional dynamic compression plates (DCP): older design; still used in some straightforward fractures.

Specialty plates: T-shaped for proximal tibia, L-shaped for distal femur, curved for acetabular fractures.

Limitations

Internal plating requires open surgical access to the fracture, which temporarily disrupts the blood supply and soft tissue around the bone. In open or infected fractures, this approach increases infection risk.

Implant removal is sometimes required if pain or implant loosening develops, though many plates remain in place for life without issues.

It is recommended that veterinarians base treatment choice on available orthopaedic equipment at their clinic and their personal experience with fracture stabilisation methods they are comfortable using. Both methods have potential risks and complications.

For the broader fracture management decision guide, see fracture management in dogs: when to splint or refer. For minimally invasive approaches to orthopedic repair, see minimally invasive orthopedic surgery for general practitioners.

Frequently asked questions

Which is better an external fixator or an internal plate?

Neither is universally better. The right choice depends on fracture type, whether the fracture is open or closed, the presence of contamination, the dog's size, and surgeon experience.

For most closed long-bone fractures in medium and large dogs, internal plating provides more reliable fixation. For open or infected fractures, external fixation is generally safer.

How long does a dog wear an external fixator?

Typically 6 to 10 weeks, until radiographic evidence of sufficient bone healing allows safe removal. The frame is removed under sedation or light anesthesia at the clinic.

Timeline varies by fracture severity, the dog's age, and healing rate.

Do internal plates need to be removed?

Not routinely. Most plates remain in place permanently without causing problems.

Removal is considered if the dog develops pain, implant loosening, or infection around the plate or occasionally in very young dogs where the plate may interfere with bone growth.

Can my dog bear weight with an external fixator?

Yes, often earlier than with splints or casts. One advantage of external fixation is that it allows some controlled weight bearing during healing, which promotes bone healing through mechanical stimulation.

Your vet will specify the allowed activity level.

What is hybrid fixation?

Hybrid fixation combines elements of both methods for example, a plate for primary stabilization with an external component for additional support.

It is used for very complex fractures where a single method cannot achieve adequate stability alone.

Joint Replacement Surgery in Dogs: Success Rates and Expectations

Discover success rates, recovery time, and expectations for joint replacement surgery in dogs. Learn when it’s the right option for your pet

Sustainable Vet Group

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.

Arthroscopy in Veterinary Orthopedics: Indications and Benefits

Discover how arthroscopy helps diagnose and treat joint issues in pets. Learn key indications, benefits, and recovery details

Sustainable Vet Group

What Is Arthroscopy in Veterinary Orthopedics?

Arthroscopy is a minimally invasive surgical technique used to look inside your pet’s joints. It involves making small incisions to insert a tiny camera (arthroscope) and special instruments. The camera sends real-time images to a screen, allowing the surgeon to see and treat joint problems without fully opening the joint.

Unlike traditional open joint surgery, arthroscopy causes less tissue damage, smaller scars, and quicker healing. It’s especially useful for diagnosing and treating conditions like ligament damage, joint inflammation, or loose cartilage. Because it offers better visibility with less pain and swelling, more vets are using it in modern orthopedic care.

Arthroscopy is commonly performed on the shoulder, elbow, stifle (knee), and hip joints. It allows precise treatment with fewer complications, making it a preferred option for both diagnosis and surgery in many orthopedic cases.

Diagnostic Benefits of Arthroscopy

Arthroscopy gives veterinarians a clear, direct view inside the joint, which is not possible with radiographs or even CT scans. This technique helps detect issues that might be missed with imaging alone, especially soft tissue problems. Because the camera goes directly into the joint, the surgeon can see the cartilage, ligaments, and joint surfaces in real time.

Here are some key diagnostic benefits of arthroscopy:

  • Direct visualization of joint interiors helps identify problems right at the source.
  • Cartilage damage, such as softening, thinning, or flaking, is seen clearly.
  • Ligament injuries, including partial or early tears, are more accurately diagnosed.
  • Subtle abnormalities, like joint inflammation or loose fragments, are easier to detect.
  • Better than radiographs or CT scans for spotting soft tissue problems like meniscal tears.
  • Synovial fluid or tissue samples can be collected during the procedure for lab testing.

Overall, arthroscopy improves the accuracy of diagnosis, allows early treatment planning, and reduces the need for exploratory surgery. It helps vets make more informed decisions and improves outcomes for dogs with joint issues.

Indications: When Is Arthroscopy Used in Veterinary Orthopedics?

Arthroscopy is commonly used in veterinary orthopedics to diagnose and treat joint problems with less pain and faster recovery. It is especially helpful in joints where precision matters and where early treatment improves long-term outcomes.

1. Elbow Joint Conditions

The elbow is one of the most common joints treated with arthroscopy in dogs, especially large breeds. Common conditions include:

  • Fragmented Medial Coronoid Process (FMCP): Arthroscopy allows removal of small bone fragments and smoothing of rough surfaces.
  • Osteochondritis Dissecans (OCD): Loose cartilage is removed with minimal joint trauma.
  • Ununited Anconeal Process (UAP): Surgeons can evaluate the extent of separation and remove or reattach the piece.
  • Elbow incongruity: Arthroscopy helps detect joint mismatch early, guiding further surgical decisions.

This joint benefits from arthroscopy because of its complexity and the difficulty of seeing problems on X-rays.

2. Shoulder Joint Conditions

Shoulder arthroscopy is often used to diagnose and treat soft tissue injuries that cause lameness. Key conditions include:

  • OCD of the shoulder: Cartilage flaps are easily identified and removed with minimal damage.
  • Biceps tendon pathology: Allows inspection and treatment of tendon inflammation or rupture.
  • Medial shoulder instability: Helps confirm ligament stretching or damage and guide surgical repair.

Because shoulder injuries can be hard to detect with imaging, arthroscopy is a valuable diagnostic and treatment tool in active dogs.

3. Stifle (Knee) Joint Conditions

Arthroscopy is useful in diagnosing and treating stifle joint problems, especially when combined with surgical repair. Common indications:

  • Cranial cruciate ligament rupture: Arthroscopy can confirm partial or complete tears and assess secondary damage.
  • Meniscal tears: Allows clear visualization and precise removal of torn cartilage.
  • OCD of the femoral condyle: Helps detect and treat cartilage defects in the knee joint.

In many cases, arthroscopy is done before or during surgery like TPLO to evaluate joint health and improve surgical outcomes.

4. Other Joints (Selective Use)

Though less common, arthroscopy can be used in other joints when imaging is unclear or precision is needed:

  • Hip joint: Occasionally used to examine cartilage damage or joint laxity in young dogs.
  • Tarsus (hock): Useful in complex cases with suspected OCD or instability.
  • Carpus (wrist): Allows diagnosis of ligament injuries or chronic inflammation in small breeds.

These joints are smaller and harder to access, so arthroscopy is used selectively by experienced surgeons.

Therapeutic Uses of Arthroscopy

Arthroscopy is not only helpful for diagnosing joint problems but also plays an important role in treatment. Because it uses small incisions and specialized instruments, it causes less damage than traditional surgery and speeds up recovery.

Here are key therapeutic uses of arthroscopy in veterinary orthopedics:

  • Removal of loose bone or cartilage fragments: Fragments from injuries or conditions like OCD can cause pain and joint damage. Arthroscopy allows precise removal without opening the whole joint.
  • Debridement of damaged cartilage: Worn or injured cartilage can be trimmed or smoothed to reduce pain and slow joint degeneration.
  • Lavage in septic joints: In infected joints, arthroscopy allows joint flushing (lavage) to remove pus, bacteria, and debris, helping the joint heal faster.
  • Treatment of partial ligament tears: Minor tears, such as early cruciate ligament damage, can be cleaned and evaluated to guide future treatment.
  • Joint flushing to reduce inflammation: In dogs with chronic joint inflammation or immune-mediated arthritis, flushing out the joint helps decrease swelling and improve comfort.

Arthroscopy offers a way to treat problems directly with minimal trauma, which leads to faster healing, less scarring, and better long-term joint function.

Benefits of Arthroscopy Compared to Traditional Surgery

Arthroscopy has become a preferred choice in veterinary orthopedics because it offers many benefits over traditional open joint surgery. By using small incisions and a camera, it reduces trauma and improves healing outcomes.

Key benefits include:

  • Smaller incisions = reduced soft tissue trauma: The small entry points cause less damage to muscles and skin, which helps with faster healing and less scarring.
  • Faster post-op recovery time: Dogs often return to gentle activity sooner than with traditional surgery. This can shorten the overall rehab period.
  • Lower pain levels for the patient: Less tissue damage means less pain after surgery. Many dogs show improved comfort within a few days.
  • Reduced risk of infection: Smaller wounds and shorter procedure times lower the chance of bacteria entering the joint.
  • Shorter anesthesia and hospital stay durations: Arthroscopy usually takes less time, which means reduced anesthesia risk and shorter clinic stays.
  • Improved precision due to magnified view: The camera gives a clear, enlarged view of the joint, helping the surgeon see tiny structures and treat the exact problem.

Overall, arthroscopy allows better care with fewer risks and a smoother recovery, making it a valuable tool in modern veterinary surgery.

Limitations and Considerations

While arthroscopy offers many benefits, it’s not the right choice for every case. There are certain limitations and factors to consider before choosing this technique for your dog.

Here are key points to keep in mind:

  • Not suitable for very small joints or advanced joint disease: In very small dogs or cats, the joint space may be too tight for the instruments. Arthroscopy is also less effective when the joint has severe arthritis or bone deformity.
  • Requires advanced training and specialized equipment: Not all veterinary clinics offer arthroscopy. It needs a skilled surgeon with special tools and experience, which may limit availability.
  • In rare cases, may need to convert to open surgery: If the problem is too complex or the joint is hard to access, the surgeon may switch to a traditional open approach during the procedure.
  • Cost considerations depending on setup and expertise: Arthroscopy can be more expensive than standard surgery due to the high cost of equipment and the advanced training required.

Despite these limitations, arthroscopy remains a valuable option for many joint conditions. Your veterinarian will help you decide if it’s the right choice based on your pet’s size, diagnosis, and overall health.

Prognosis and Expected Outcomes

Arthroscopy has a high success rate when used in the right cases and performed by an experienced surgeon. Most dogs recover well and show noticeable improvement in comfort and mobility.

Here’s what you can expect from arthroscopy:

  • High success rate in properly selected cases: When done for the right joint condition—such as early ligament injury, cartilage damage, or OCD—arthroscopy provides excellent results with fewer complications.
  • Faster return to function and normal activity: Because the procedure is minimally invasive, dogs often regain mobility sooner than with traditional surgery. Most pets can begin light activity within a few weeks.
  • Early intervention improves long-term joint health: Treating joint problems early, before there is severe damage, helps protect the joint. This can delay or prevent long-term issues like chronic pain or joint deformity.
  • 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.

Overall, arthroscopy offers a strong long-term outcome with less pain, quicker healing, and better joint function—especially when performed before the disease becomes advanced. Regular follow-up and proper rehab are key to success.

Final Thoughts

Arthroscopy is a modern, minimally invasive technique that offers both diagnostic and therapeutic benefits in veterinary orthopedics. 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.

It’s especially helpful for early-stage joint problems, where quick action can protect the joint and reduce long-term damage. However, not every case is a match for arthroscopy. Factors like joint size, disease severity, and available expertise must be considered.

Early diagnosis plays a major role in successful outcomes. If your dog shows signs of joint pain, lameness, or reduced activity, don’t wait. A timely exam can make all the difference. Always consult a board-certified veterinary surgeon to determine if arthroscopy is the right choice for your dog’s condition and recovery.

FAQs About Arthroscopy in Veterinary Orthopedics

Is arthroscopy painful for dogs or cats?

Arthroscopy is less painful than traditional open joint surgery because it uses small incisions and causes less tissue damage. Most pets experience mild discomfort, which is managed with pain medication. Many animals begin walking comfortably within a few days and show steady improvement as healing progresses.

How long does recovery take after arthroscopy?

Recovery time after arthroscopy is usually shorter than open surgery. Most pets start gentle activity within 2 to 3 weeks. Full recovery takes about 6 to 8 weeks, depending on the joint treated and overall health. A structured rehab plan, including rest and controlled exercise, helps ensure the best outcome.

How much does veterinary arthroscopy cost?

The cost of arthroscopy can range from $2,000 to $4,000 or more, depending on the joint treated, clinic location, surgeon experience, and whether therapeutic procedures are done. Additional fees for diagnostics, anesthesia, and follow-up care may apply. Always ask for a full estimate before scheduling the procedure.

Can small breed dogs undergo arthroscopy?

Yes, small breed dogs can have arthroscopy, especially for shoulder, elbow, or stifle issues. However, very tiny joints may be too small for the instruments. A skilled veterinary surgeon will evaluate your dog’s size and joint structure to decide if arthroscopy is a safe and effective option.

Is arthroscopy better than MRI or CT for joint problems?

Arthroscopy gives a real-time, direct view of the inside of the joint, making it better for diagnosing cartilage, ligament, or meniscus problems. MRI and CT scans are useful for imaging bones and deeper structures, but they can miss soft tissue issues that arthroscopy can clearly reveal and treat at the same time.

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

Sustainable Vet Group

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.

Fracture Management in Dogs: When to Splint or Refer?

Fracture Management in Dogs: When to Splint or Refer?

Learn when to splint and when to refer dog fractures. A practical guide for vets to make the right call in canine fracture management

Sustainable Vet Group

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:

  1. Immediate wound irrigation and debridement under anesthesia
  2. Temporary stabilization (bandage)
  3. Systemic antibiotics
  4. 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.

For recovery care after fracture surgery, see orthopedic surgery home care guide. For the referral decision framework across orthopedic conditions, see when to refer orthopedic cases. For the full specialist referral process, see what is veterinary referral surgery.

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.

Feline Orthopedic Conditions: Signs of Hidden Lameness

Learn how to spot hidden lameness in cats, recognize common feline orthopedic conditions early, and keep your cat healthy and comfortable

Sustainable Vet Group

Cats are exceptional at concealing pain. This is not stubbornness it is a deeply ingrained survival instinct. In the wild, a visibly lame or injured animal becomes prey.

Domestic cats retain this drive to mask weakness, which means orthopedic disease in cats is frequently underdiagnosed and undertreated.

 

Quick answer: Cats rarely limp overtly even with significant orthopedic pain. Reliable signs of hidden lameness include reduced jumping, reluctance to use stairs, grooming changes, and irritability when handled. OA affects 60 to 90% of older cats. Hip dysplasia affects up to 46.7% of some pedigree cat populations.

 

Key takeaways

  • Cats rarely limp overtly even with significant joint pain; behavioral changes are the primary indicator of orthopedic disease
  • 60 to 90% of older cats have radiographic OA but most owners do not recognize it as a clinical problem
  • Hip dysplasia affects up to 46.7% of pedigree cats in some studies, with Maine Coons and Siamese most commonly affected
  • Reduced jumping height or frequency is one of the earliest reliable signs of feline orthopedic pain
  • Examining lame cats is challenging: they are often anxious and aggressive in the clinic; a calm, low-stress approach is essential
  • CT is the most reliable non-invasive tool for subtle elbow and coronoid lesions that radiographs may miss

Why cats hide orthopedic pain

Cats can often much better compensate for pelvic limb lameness and hide their pain, and as a result, owners are less likely to notice this condition.

Osteoarthritis is common in cats but may not be noticed because cats often hide signs of pain. Approximately 60 to 90% of older cats have osteoarthritis.

Examination of the lame cat can be difficult. Owner history is often not helpful because most injuries are not witnessed. Cats can be highly anxious in a hospital setting and may be aggressive.

The clinical implication is clear: waiting for a cat to present with an obvious limp means waiting for a level of pain that most cats will never openly display.

Earlier detection requires recognizing the subtler behavioral signals.

Behavioral signs of hidden orthopedic pain in cats

Rather than an overt limp, cats with orthopedic disease typically show:

Changes in jumping behavior:

  • Reduced jumping height landing lower than usual on furniture
  • Reduced jumping frequency choosing not to jump when they previously would
  • Hesitating before jumping, or looking for an alternative route up

Activity and movement changes:

  • Reluctance to use stairs
  • Slower, more deliberate movement
  • Spending more time on lower surfaces
  • Stiffness when rising after rest, particularly in the morning

Grooming changes:

  • Reduced grooming of the hindquarters and tail base (hips or spine painful to flex toward)
  • Matted coat in areas the cat cannot reach comfortably
  • Overgrooming of a painful limb (licking at the joint or foot)

Litter box behavior:

  • Difficulty squatting defecating outside the box, particularly in cats with hip pain
  • Reluctance to step over a high-sided litter box

Behavioral and temperament changes:

  • Increased irritability, especially when touched around the affected area
  • Withdrawal from family interaction
  • Reduced playfulness or hunting behavior
  • Vocalizing when handled or picked up

The main clinical signs are decreased activity and reluctance to jump on higher places, reluctance to use stairs and to squat when defecating and defecation outside of the litter box; signs of pelvic limb lameness are rare.

Common feline orthopedic conditions

Osteoarthritis (OA)

The most prevalent orthopedic condition in cats, particularly in middle-aged and older animals.

The joint cartilage in freely moving joints may degenerate over time, leading to loss of joint movement and, in many cases, pain. Joint degeneration can be caused by trauma, infection, the body's immune system, or malformation during development.

The elbows and hips are most commonly affected, followed by the stifles and spine.

Management is multimodal: weight management, environmental modifications (ramps, low-sided litter boxes, raised food bowls), NSAIDs formulated for cats (meloxicam), and joint supplements.

Hip dysplasia

Hip OA is relatively common in cats but is often not recognised, either because cat owners do not appreciate the pelvic limb lameness or because cats are better able to compensate for the resulting functional impairment.

The prevalence of hip joint dysplasia in all pedigree cats was 46.7%, of which 78% of cats had bilateral dysplasia. Dysplasia was mainly mild to moderate; however, 6.1% of hip joints showed signs of severe hip dysplasia in Maine Coon and Siberian cats.

Fortunately, hip dysplasia is rarer in cats than in dogs, and many cats with hip dysplasia may never show symptoms. This may occur because cats are better at compensating for hind limb lameness and hiding their pain.

Most cats with hip dysplasia are managed conservatively. Surgical options exist for severe cases.

Patellar luxation

Patellar luxation was noted in 32.7% of pedigree cats, present bilaterally in 91.4%, and was grade 1 or 2 in most cats.

Most feline patellar luxations are low-grade and clinically silent. Higher-grade luxations causing intermittent lameness may require surgical correction.

Fractures

Feline fractures are a prevalent orthopedic issue in cats. Accidents often result in these injuries, with the shoulder, elbow, wrist, knee, and ankle joints being the most susceptible to fracture.

Cats sustaining high-rise falls (high-rise syndrome) often present with thoracic, facial, and forelimb injuries. A cat presented after a fall with any lameness or reluctance to bear weight requires radiographic assessment.

Cranial cruciate ligament (CCL) disease

Mediolateral and craniocaudal radiographs of a seven-year-old domestic shorthair cat showed cranial cruciate ligament rupture.

CCL rupture is less common in cats than dogs, but it does occur, particularly in middle-aged neutered cats. Unlike in dogs, some cats achieve functional stability through fibrosis without surgery.

Feline vs. canine orthopedic anatomy: key differences

The cat appendicular skeleton has numerous subtle differences compared to dogs. Cats tend to have a more shallow acetabular fossa and this must be taken into account when interpreting radiographs for hip dysplasia. Cats have a high degree of pronation and supination in their elbow joint, and about 40% will have a sesamoid in the supinator muscle that can be mistaken for a chip fracture.

These anatomical differences mean that normal feline radiographic findings can be misinterpreted as pathology, and vice versa. Feline orthopedic radiographs should be interpreted with species-specific reference ranges in mind.

Assessment approach

The feline orthopedic examination requires a low-stress approach. Allow the cat to settle in the room before beginning. Observe spontaneous movement first: how the cat rises, walks, and places each foot.

Palpation of joints should be systematic but gentle, noting pain responses, crepitus, reduced range of motion, and muscle atrophy.

The most commonly reported physical examination findings in cats with hip dysplasia are pain and crepitus upon extension of the hips, and muscle atrophy.

For subtle lesions, particularly of the elbow, CT provides better sensitivity than radiography alone.

For the referral decision framework, see when to refer for orthopedic surgery: surgical vs non-surgical cases. For post-surgical home care in cats, see post-op home care for pets after orthopedic surgery.

Frequently asked questions

How can I tell if my cat is in orthopedic pain if it isn't limping?

Watch for behavioral changes: reduced jumping, reluctance to use stairs, grooming changes, litter box avoidance, and increased irritability when touched.

These are often more reliable indicators of feline orthopedic pain than gait changes, which cats suppress effectively.

Is arthritis common in cats?

Yes. Radiographic evidence of OA affects 60 to 90% of older cats.

The condition is significantly underdiagnosed because cats compensate so well that owners rarely notice clinical signs until the disease is advanced.

My cat is a Maine Coon. Should I be concerned about hip dysplasia?

Maine Coons are one of the most commonly affected breeds, with hip dysplasia rates of 18 to 21% reported in some studies.

Annual veterinary checks including orthopedic assessment are worthwhile, even in the absence of obvious clinical signs.

Can cats have surgery for orthopedic conditions?

Yes. Fracture repair, patellar luxation correction, femoral head ostectomy for hip disease, and CCL repair are all performed in cats. Outcomes are generally good.

The decision to pursue surgery depends on severity, the cat's overall health, and owner circumstances.

How should I modify my home for a cat with arthritis?

Lower-sided litter boxes, ramps to reach favourite resting spots, raised food and water bowls, soft bedding in warm locations, and healthy weight management all significantly reduce the daily pain burden of OA.

Elbow Dysplasia in Dogs: Early Detection and Referral Guidelines

Learn how to spot early signs of elbow dysplasia in dogs and when to refer for specialist care to prevent long-term joint damage

Sustainable Vet Group

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.
