"Failure rate" is used loosely when owners discuss TPLO, which can cause significant confusion. A complication is not the same as a failure.

Understanding what the published data actually shows and distinguishing minor complications from true surgical failures gives owners a much clearer picture of what to expect.

Quick answer: The overall TPLO complication rate is 10 to 34% across studies; most are minor. Major complications requiring reoperation occur in 2 to 7%. Infection is the most common major complication. Long-term good outcomes are reported in 90 to 93% of dogs.

Key takeaways

• Overall complication rate is 10 to 34% across published studies; most complications are minor and resolve without additional surgery
• Major complication rate requiring reoperation is 2 to 7%: a 1,000-dog study found 14.8% overall with 6.6% major complications
• SSI is the most common major complication: 2.9% to 25.9% across studies; giant breeds over 50 kg are at highest risk
• Small dogs under 15 kg have significantly lower complication rates: 4.44% in one 90-dog study, with no revisions
• Good to excellent long-term outcomes in 90 to 93% of dogs: the complication rate does not equal the failure rate
• Surgeon experience is the most modifiable risk factor: complication rates are consistently lower at high-volume specialty centers with board-certified surgeons

Defining "failure" vs. "complication"

This distinction is critical for interpreting the literature and for setting owner expectations accurately.

Complication: any deviation from the expected post-operative course. This includes minor findings like superficial wound dehiscence, mild swelling, or radiographic evidence of delayed osteotomy healing with no clinical signs. Many publications include these minor events in their complication rates.

Major complication: an event requiring additional surgical intervention or causing extended lameness. Major complications represent the subset of complications that meaningfully affect recovery and outcome.

Failure: the most restrictive definition surgery that did not achieve its goal of stifle stabilization, resulting in persistent instability and requiring revision with a different technique. True failure in this sense is uncommon after TPLO.

What published complication data shows

Overall complication rates

Vetamac confirms: complication rates following TPLO surgery range from 14% to 34%, with less than 10% of cases requiring a second surgery.

PMC (intraoperative bacterial culture study) confirms: the complication rate of TPLO varies between 10% and 34%, with 2 to 4% requiring surgical revision.

Today's Veterinary Practice reports a 14.8% complication rate in 1,000 TPLO patients (6.6% major — requiring repeat surgery or extended lameness), including 2.8% late meniscal injury and 6.6% infections.

Infection rates

Infection is the most common major complication and the one with the greatest variation by dog size and surgical setting.

PMC confirms: SSI rate after TPLO is reported to be 2.9% to 25.9% across studies, which is higher than other clean orthopedic surgeries (2.0 to 6.7%).

Surgical site infection rates of 21.3% to 25.9% have been reported specifically for giant-breed dogs weighing over 50 kg.

The implant removal rate due to infection is 3 to 7.4% per published literature (PMC PRP study; ResearchGate implant removal study).

Complication rates by dog size

Dog size is a consistent predictor of complication risk.

PLOS One retrospective (90 dogs under 15 kg): overall complication rate 4.44%, with no complications requiring surgical revision.

The study confirms: the complication rate in dogs under 15 kg is less than that historically reported in heavier dogs.

PubMed retrospective (small and medium dogs, 2.0 and 2.7 mm plates): overall complication rate 36%.

The most common complications were radiographic evidence of delayed healing (9%), patellar tendon thickening (8%), and tibial tuberosity fracture (6%). Only 7% of complications were major.

PLOS One confirms: the TPLO complication rates range from 10% to 34% and vary in severity from swelling and bruising to fractures and osteomyelitis.

Implant-related complications reportedly occur in under 10% of all TPLO procedures.

Long-term success rates

Complication rates must be interpreted alongside long-term success rates.

The retrospective cohort study comparing TPLO, Tightrope, and TTA found: function greater than 1 year after surgery was 93.1% for TPLO, 92.7% for Tightrope, and 89.2% for TTA.

SustainableVet.org confirms: good to excellent long-term outcomes are achieved in 90.4% of patients up to 6.8 years after TPLO surgery; 80 to 90% of owners are satisfied with their dog's long-term recovery.

A dog can have a complication even a significant one like an infection and still achieve a good long-term outcome after the complication is resolved.

The complication rate and the long-term success rate address different aspects of the outcome.

Factors that affect complication and failure rates

Surgeon experience and volume

This is the most consistently cited modifiable risk factor. High-volume specialty centers and board-certified surgeons consistently report lower complication rates than general practitioners performing occasional TPLO procedures.

Surgical efficiency, technique precision, and post-operative protocol standardization all contribute.

Dog size and body weight

Larger dogs generate higher joint forces, have larger dead space at the surgical site, and place more mechanical demand on the implant during healing.

These factors contribute to the higher complication rates seen in large and giant breeds.

Excessive tibial plateau angle (TPA)

Dogs with TPA above 35 degrees (excessive TPA, or eTPA) have higher complication rates.

Today's Veterinary Practice notes: owner-perceived outcome was superior for eTPA group dogs when TPLO resulted in TPA of 14 degrees or less compared to those with TPA greater than 14 degrees.

Postoperative complications were more common in dogs with eTPA.

Post-operative activity restriction compliance

Dogs that are over-active during recovery have higher rates of implant complications, seroma formation, and wound complications.

Strict adherence to the prescribed restriction protocol is the owner's primary contribution to reducing complication risk.

Frequently asked questions

What is the TPLO failure rate?

Depends on how "failure" is defined. If failure means any complication: 10 to 34% across studies. If failure means major complications requiring surgery or causing extended lameness: 2 to 7%.

If failure means persistent instability requiring revision with a different technique: uncommon and not consistently reported across large series.

Is TPLO safe for large breed dogs?

Yes, but with a higher complication risk than small dogs. Vetamac confirms: for large breeds, TPLO is still the gold standard, providing better long-term stability than alternatives.

The higher complication rate in large dogs reflects the greater mechanical demands and surgical challenges, not a fundamental unsafety of the procedure.

What percentage of TPLO dogs need a second surgery?

Across published studies, 2 to 10% require a second surgical intervention. Most second surgeries address infection (requiring plate removal), late meniscal tears (requiring partial meniscectomy), or implant complications.

Does my dog's vet experience affect failure rate?

Yes, substantially. Surgeons performing fewer than a set number of TPLO procedures per year have higher complication rates than high-volume specialists.

This is one reason referral to a board-certified orthopedic surgeon (ACVS diplomate) is recommended for TPLO.

If my dog has a complication, does that mean the TPLO failed?

Not necessarily. Many dogs who develop complications including infections requiring plate removal still achieve good to excellent long-term function after the complication is resolved.

The complication rate and the long-term outcome are different measures.

A clicking or popping sound from the stifle after TPLO surgery is a common observation that owners report, especially during the first weeks of recovery.

It is not automatically a sign of a problem.

The clinical significance depends on what accompanies the click: is the dog bearing weight and recovering normally, or is clicking associated with lameness, pain, or a trajectory reversal?

Quick answer: Post-TPLO clicking most often reflects normal joint adjustment, soft tissue movement, or cavitation. The most clinically important cause is a meniscal tear, producing a meniscal click with pain and returning lameness. Clicking without lameness or pain in early recovery is usually benign.

Key takeaways

• Most post-TPLO clicking is benign: the click typically comes from joint adjustment to new mechanics; the dog usually feels fine even when a sound is present
• The meniscal click is the clinically significant type: dogs with meniscal tears exhibit a meniscal click accompanied by lameness and pain
• Clicking with lameness or pain warrants prompt veterinary evaluation: clicking with swelling, limping, or avoiding the leg could signal instability, implant issues, or a torn meniscus
• Clicking that is isolated, early in recovery, and not associated with lameness is usually normal and improves as healing progresses
• Late-onset clicking in a previously normal recovery is more concerning than early clicking; it suggests a new event such as meniscal tear or implant loosening
• Implant loosening is a rare but serious cause of clicking: abnormal joint mechanics from loosened screws or plate produce clicking accompanied by pain and radiographic changes

What causes clicking after TPLO surgery

Normal joint adjustment

After TPLO, the tibial plateau is repositioned to a new angle. The soft tissues, tendons, and joint capsule require weeks to adapt to this new geometry.

During this adaptation period, movement can produce audible sounds as structures slide over each other or snap slightly over new contours.

TPLO Info confirms: after CCL repair, the joints adjust to new motion. The click comes from the knees. The dog usually feels fine even when a sound is present.

Soft tissue movement over the implant

The TPLO plate sits against the medial tibial surface. Tendons and fascial layers that previously moved over the normal tibial contour now move over a plate with a different profile.

This can produce audible snapping or clicking sounds during flexion and extension, particularly in the first weeks before soft tissue accommodation occurs.

Gas bubble release (cavitation)

Joint capsule distension from post-surgical effusion can trap gas in the joint space. Movement releases this gas in small pops -- the same mechanism as knuckle cracking in humans.

This is painless and harmless.

Meniscal click (most significant cause)

The medial meniscus is vulnerable to injury in CCL disease. At the time of TPLO, the surgeon assesses the meniscus and removes damaged tissue.

However, meniscal injury can occur after TPLO -- either from previously undetected damage that progresses, or from new injury in a joint that has not yet fully stabilized.

Laguna Woods Vets confirms: dogs with meniscal tears frequently exhibit a meniscal click. If damage is noted during TPLO, the meniscus is removed. If not removed, it may tear later.

SustainableVet.org confirms: symptoms of meniscal damage include clicking when the dog moves, lameness, reluctance to use the affected leg, and discomfort when bending the knee.

The meniscal click is distinguished from benign clicking by:

• Accompanying lameness (often a sudden return of limping after initial improvement)
• Pain when the stifle is manipulated on examination
• Worsening trajectory rather than improvement

Implant-related clicking (uncommon)

Plate or screw loosening generates abnormal tibial motion during weight bearing, which can produce clicking.

This is uncommon in an uncomplicated TPLO but more likely if the dog has been overactive during recovery.

Signs include pain localized to the plate site and radiographic evidence of implant migration or peri-implant bone changes.

SustainableVet.org confirms: implant failure is rare but serious; plates or screws can loosen or break if the dog is too active early, leading to discomfort and joint noises.

Normal vs. concerning clicking: a practical guide

Likely normal (benign):

• Clicking present from the first days after surgery
• No lameness associated with the click
• Dog is bearing weight and improving week by week
• Click is quiet and intermittent
• Dog does not react (wince, pull back, vocalize) when the stifle is manipulated

Warrants veterinary evaluation:

• Clicking that appears new after a period of recovery without clicking
• Clicking accompanied by lameness or reluctance to bear weight
• Dog flinches or vocalizes when the stifle is flexed
• Clicking that is getting louder or more frequent over time
• Lameness that had been improving and then reverses

SustainableVet.org confirms: contact your vet if the clicking sound is persistent or getting worse over time; a mild clicking early in recovery is normal but it should improve as healing progresses.

Meniscal tear after TPLO: what happens next

If a meniscal tear is suspected or confirmed, management depends on severity.

Mild cases: pain management with NSAIDs, joint supplements, and controlled exercise restriction. The meniscus may stabilize with conservative management if the tear is small and the joint is otherwise stable.

Cases with ongoing pain or lameness: partial meniscectomy (surgical removal of the torn portion of the meniscus) is required. This is a second surgical procedure requiring general anesthesia and a repeat recovery period.

SustainableVet.org confirms: if a meniscal tear causes ongoing pain and instability, surgery is often needed; this may involve a partial meniscectomy.

Larger dogs and clicking

Larger dogs are more likely to produce audible joint sounds during recovery. Greater body mass means greater joint loading forces, which amplify soft tissue and implant movement sounds.

SustainableVet.org confirms: larger dogs are more likely to make joint sounds during recovery; their extra weight puts more pressure on the healing leg, which can make clicking more noticeable.

This does not mean clicking in large dogs is more likely to be pathological -- only that it is more audible when it occurs.

When to contact your vet about clicking

Contact your vet promptly (same day or within 24 hours) if:

• Clicking is accompanied by lameness or non-weight bearing
• A dog that was improving begins to worsen (trajectory reversal)
• The click is producing a visible pain response
• The click appears late in recovery (after weeks of silent healing)

Contact at your next scheduled appointment (can wait):

• Intermittent clicking early in recovery without lameness
• Click that is quieter week by week
• Dog is bearing full weight and improving in function

Frequently asked questions

My dog's knee has been clicking for 3 weeks but she is not limping at all. Should I be worried?

Three weeks of clicking with no lameness and a normal, improving recovery trajectory is most likely benign joint adjustment. Monitor for lameness, pain on stifle palpation, or worsening of the click.

Mention it at your next scheduled vet appointment -- this is not an emergency call.

My dog's leg clicked once loudly while getting up, and then she held the leg up. What do I do?

Contact your vet the same day. A sudden loud click followed by acute lameness may indicate a meniscal injury event. This presentation warrants veterinary examination and likely radiographs.

Can clicking after TPLO get better on its own?

Yes -- benign mechanical clicking from joint adjustment and soft tissue accommodation typically resolves or reduces significantly over the first 4 to 8 weeks.

A meniscal click does not resolve without treatment of the meniscal tear.

Does clicking mean the plate is failing?

Not typically. Implant failure clicking is accompanied by pain and worsening lameness. Benign clicking in a comfortable, normally-recovering dog does not indicate implant failure.

Radiographs at the scheduled 6-week and 12-week appointments assess implant integrity.

My dog clicks on every step. Is that different from occasional clicking?

Consistent clicking on every step, particularly if it has a regular, reproducible pattern during weight bearing, is more likely to have a structural cause (meniscal click) than intermittent clicking.

Mention this to your vet and assess whether lameness is present.

TPLO produces predominantly positive long-term effects in most dogs, but it also produces a predictable set of changes that owners should understand and manage proactively.

Most of these effects are manageable with appropriate care. Knowing what to expect prevents owners from being surprised by normal post-TPLO findings and helps them recognize when a change requires veterinary attention.

Quick answer: The 13 key long-term effects of TPLO surgery: improved joint stability, progressive osteoarthritis, muscle atrophy, morning stiffness, cold weather sensitivity, scar tissue formation, patellar tendon thickening, permanent implant in situ, contralateral CCL rupture risk, late implant complications, behavioral changes from chronic pain, weight management challenges, and long-term monitoring requirements.

Key takeaways

• Improved joint stability is the intended and most common long-term effect: for 90 to 95% of dogs, TPLO eliminates CCL-related instability and restores near-normal function
• Progressive osteoarthritis develops in all CCL-affected stifles regardless of surgical technique: TPLO slows OA progression but does not stop it; long-term OA management is a universal requirement
• Muscle atrophy is common in the operated leg throughout recovery; the thigh may remain visibly smaller than the contralateral side for months if rehabilitation is inadequate
• Contralateral CCL rupture risk is high: SustainableVet.org confirms up to a 50% chance of tearing the opposite CCL within a few years; the same degenerative process affects both stifles
• The TPLO plate and screws are permanent in the vast majority of cases: removal is only performed when complications arise; routine plate removal is not standard practice
• Weight management is the most impactful long-term owner-controlled variable: excess weight accelerates OA progression; maintaining ideal body condition is the primary long-term prevention strategy

The 13 long-term effects

1. Improved joint stability and mobility

The primary intended effect. The osteotomy and plate fixation permanently change the tibial plateau geometry, eliminating the cranial tibial thrust that caused instability.

For 90 to 95% of dogs, this produces lasting functional improvement: return to normal gait, ability to run and play, and freedom from the pain of unstable joint loading.

SustainableVet.org confirms: over 90% of dogs regain full limb function within a year; with proper care, many dogs remain active for 8 to 10 years after surgery.

2. Progressive osteoarthritis

The most universal long-term challenge. CCL disease initiates an arthritis process in the stifle that continues regardless of surgical outcome.

TPLO reduces the rate of progression and the severity of clinical signs compared to other treatment options, but OA continues.

Clinical signs of progressing OA emerge gradually over months and years: stiffness after rest, reluctance to run, difficulty climbing, and behavioral changes associated with chronic low-grade pain.

Management: weight management, omega-3 fatty acids, glucosamine and chondroitin, NSAIDs for flares, hydrotherapy, physiotherapy.

3. Muscle atrophy and asymmetry

The operated leg loses muscle mass rapidly during the restriction period and slowly rebuilds during rehabilitation. Full recovery of muscle symmetry takes 4 to 6 months in most dogs.

In some dogs -- particularly those with inadequate rehabilitation or ongoing joint pain -- visible thigh circumference asymmetry persists long-term.

Vetplayas confirms: due to reduced use during recovery and altered movement patterns post-surgery, muscles around the operated leg may weaken and shrink.

4. Morning stiffness

Morning stiffness -- the dog rises from sleep stiffly and walks awkwardly for the first few minutes before loosening up -- is one of the most common long-term effects of post-TPLO OA.

It typically develops months to years after surgery and gradually worsens as the dog ages.

This stiffness should not be confused with acute lameness. It consistently improves within 5 to 10 minutes of movement.

If it does not improve, or if the dog refuses to bear weight on waking, contact your vet.

5. Cold weather sensitivity

Dogs with OA in the operated stifle commonly show increased stiffness and lameness during cold weather or when barometric pressure changes.

This reflects the sensitivity of arthritic joints to temperature and pressure changes -- the same phenomenon seen in human arthritis.

Management: NSAIDs or joint supplements maintained year-round; warming the dog's sleeping area; a brief gentle walk before expecting full function in cold conditions.

6. Scar tissue formation

The surgical dissection and bone healing produce scar tissue in and around the stifle. This fibrous tissue generally has a beneficial stabilizing effect, contributing to long-term joint stability.

In some dogs, however, periarticular fibrosis restricts range of motion and causes stiffness that persists long after bone healing is complete.

Regular low-impact exercise and physiotherapy help maintain range of motion and prevent excessive fibrous tissue restriction.

7. Patellar tendon thickening

Fibrous thickening of the patellar tendon is a recognized long-term change after TPLO. It is typically subclinical -- detected on palpation at follow-up examinations but not producing clinical lameness.

In a small number of dogs, it contributes to reduced range of motion.

8. Permanent implant in situ

The TPLO plate and screws are designed to remain in place for life. In the vast majority of dogs, the implant is never removed and causes no long-term problems.

SustainableVet.org confirms: these implants are meant to stay in place permanently. In rare cases, some dogs may develop infections around the implant or experience loosening of the hardware over time.

The plate is palpable under the skin on the medial tibial surface. This is normal and not a complication.

9. Contralateral CCL rupture

The degenerative process that caused one CCL to rupture typically affects both stifles.

SustainableVet.org confirms dogs have up to a 50% chance of tearing the CCL in the opposite knee within a few years.

RCVS confirms approximately 50% of dogs develop CCL disease in the other hind limb.

This is not a complication of TPLO -- it is the natural history of bilateral CCL disease.

Monitoring the contralateral stifle for early signs of instability, effusion, or lameness is appropriate in all TPLO dogs.

10. Late implant-associated complications

Implant-related complications -- loosening, late infection from hematogenous seeding, or implant irritation -- can occur years after the original surgery. These are uncommon but recognized long-term effects.

Signs: new lameness focused at the plate site, warmth or swelling over the plate, a new draining tract in previously healed skin. Any of these warrants prompt veterinary assessment.

11. Behavioral changes

Chronic joint pain from progressive OA, late meniscal injury, or implant irritation can produce subtle behavioral changes: reduced engagement in play, reluctance to walk, increased irritability, or reduced stair use.

These changes are often attributed to aging but may reflect treatable pain.

Annual or semi-annual pain assessments, including use of validated canine pain scales (Canine Brief Pain Inventory, Helsinki Chronic Pain Index), help detect behavioral pain signs before they become severe.

12. Weight management challenges

Activity restriction during recovery predisposes many dogs to weight gain. Excess weight gained during the 8 to 12 week restriction period is then carried on the healing joint for the following months.

Long-term obesity accelerates OA progression and is the most modifiable risk factor for long-term joint health.

Medcovet confirms: because activity is restricted, veterinary teams may recommend reducing food intake by about 30% during recovery to prevent weight gain and extra strain on the knee joint.

13. Long-term monitoring and supplement requirements

TPLO dogs benefit from long-term monitoring (every 6 to 12 months after full recovery) to assess:

• Arthritis progression radiographically and clinically
• Body condition score and weight
• Contralateral stifle stability
• Implant integrity (radiographs every 1 to 2 years in some protocols)

Joint supplements (omega-3 fatty acids at anti-inflammatory doses; glucosamine and chondroitin) and ongoing weight management are the primary preventive interventions for the long-term joint changes that TPLO does not prevent.

Frequently asked questions

Will my dog develop arthritis even if the TPLO was successful?

Yes. All CCL-affected stifles develop progressive osteoarthritis regardless of surgical technique or outcome.

TPLO reduces the rate of progression and the severity of clinical signs compared to non-surgical management and lateral suture repair.

The goal of TPLO is not to prevent OA but to minimize it while restoring function.

How long will the TPLO plate last?

The plate is designed to be permanent. Published long-term follow-up data at 6.8 years shows 90.4% of dogs with good to excellent results -- with the plate in place.

Plate complications requiring removal occur in 3.5 to 7.5% of cases.

My dog had TPLO 2 years ago and is now limping. Is this related to the surgery?

Possibly. Two-year post-TPLO lameness most commonly results from progressive OA, late meniscal tear, late implant-associated infection (hematogenous seeding), or contralateral CCL disease.

A veterinary examination and radiographs of both stifles will identify the cause and guide treatment.

Does the opposite leg always need TPLO as well?

Not necessarily and not always at the same time. RCVS confirms approximately 50% of dogs develop CCL disease in the opposite hind limb.

When and whether the second stifle requires surgery depends on whether the second CCL has ruptured or become significantly unstable. Annual monitoring of the contralateral stifle is appropriate.

Can TPLO dogs still live active lives long-term?

Yes. Most do. SustainableVet.org confirms that with proper care, many dogs remain active for 8 to 10 years after surgery.

The keys are weight management, regular low-impact exercise, joint supplements, and addressing pain or complications promptly.

TPLO is the most commonly performed surgery for CCL rupture in dogs and the most commonly misunderstood.

Misconceptions about TPLO cause unnecessary hesitation, lead some owners to choose inferior alternatives, and create unrealistic expectations about recovery.

This guide addresses the 10 most common myths directly -- with evidence-based clarification for each.

Quick answer: The most persistent TPLO myths: that dogs can manage without surgery, that TPLO is only for large breeds, that recovery takes a few weeks, that the plate must be removed after healing, and that TPLO prevents arthritis. All are false. TPLO has a 90 to 95% success rate.

Key takeaways

• Myth: "My dog can heal without surgery": dog knee anatomy differs fundamentally from human; without surgery, severe OA, meniscal tearing, and chronic lameness are expected in most dogs over 15 kg
• Myth: "TPLO is only for large dogs": SustainableVet.org confirms TPLO is just as effective for small and toy breeds; the biomechanical correction is appropriate regardless of size
• Myth: "Recovery only takes a few weeks": bone healing takes 8 to 12 weeks; full muscle recovery takes 4 to 6 months; 8 to 12 weeks is the minimum restriction period
• Myth: "The plate needs to be removed after healing": the TPLO plate is designed to be permanent; removal is only performed when complications arise
• Myth: "TPLO prevents arthritis": all CCL-affected stifles develop progressive OA regardless of surgical technique; TPLO reduces OA progression but does not prevent it
• Myth: "Dogs are in severe pain after TPLO": SustainableVet.org confirms this is a misconception; modern multi-modal pain management controls post-surgical pain effectively

Myth 1: "My dog can heal without surgery"

The truth: dogs and humans have fundamentally different knee anatomy. In humans, the flat tibial plateau and strong surrounding musculature allow some CCL tears to be managed conservatively with physical therapy and bracing. In dogs, the tibial plateau slopes steeply downward, generating a cranial shear force that the absent CCL cannot resist. Without surgical correction of this force, the joint remains mechanically unstable with every weight-bearing step.

TPLO Info confirms: dogs and humans respond very differently to CCL tears. Without surgery, severe OA can develop, meniscal tearing can occur, and other side effects may be present.

Conservative management (strict rest, weight management, joint supplements, physical therapy) can provide temporary improvement, particularly in small dogs and partial tears.

For most dogs over 15 kg with complete CCL rupture, conservative management does not restore normal joint stability, and progressive lameness, OA, and joint deterioration are the expected outcome.

Who can be managed conservatively?

• Very small dogs (under 10 to 15 kg) with partial tears and low activity levels
• Dogs with significant comorbidities where anesthetic risk outweighs surgical benefit
• Owners who decline surgery after being fully informed of expected outcomes

For all other dogs -- medium and large breeds, young dogs, active dogs, complete ruptures -- surgery produces substantially better outcomes than conservative management.

Myth 2: "TPLO is only for large dogs"

The truth: TPLO was originally developed for large and giant breeds because they were the most severely affected by CCL disease and the most poorly served by lateral suture stabilization. But TPLO corrects the underlying biomechanical problem (excessive tibial plateau angle) in any dog, regardless of size.

SustainableVet.org confirms: TPLO was initially developed for large dogs due to biomechanical challenges, but has been found just as effective for small and toy breeds.

For small dogs, both TPLO and lateral suture stabilization can achieve good outcomes.

The decision for a small dog should be based on the dog's TPA, activity level, and individual assessment -- not a blanket assumption that TPLO is unnecessary.

Myth 3: "TPLO recovery only takes a few weeks"

The truth: bone healing takes 8 to 12 weeks. This is the period of activity restriction. But bone healing and functional recovery are not the same thing. Full muscle rebuilding and joint function restoration takes 4 to 6 months from surgery.

Canada Vet Express confirms: recovery is gradual; most dogs begin walking within a few days and return to normal activity within 3 to 4 months with proper care.

The 8 to 12 week bone healing timeline means:

• Activity restrictions are in place for 8 to 12 weeks minimum
• Radiographic confirmation of healing is required before restrictions are lifted
• Progressive return to full activity follows the radiographic clearance

After restrictions are lifted, the operated leg continues to rebuild strength and coordination for months. For sport dogs and working dogs, the return-to-sport protocol extends to 7 to 9 months from surgery.

Myth 4: "The TPLO plate needs to be removed after the bone heals"

The truth: the plate is designed to remain in place permanently. It does not need to be removed when the osteotomy heals. Routine plate removal is not standard practice in veterinary orthopedics.

SustainableVet.org confirms: these implants are meant to stay in place permanently, but in rare cases they can cause problems; removal is only performed when complications arise.

When plate removal is performed:

• Deep implant-associated infection requiring source removal
• Implant failure (breakage, loosening causing instability)
• Persistent implant irritation producing clinical lameness specifically attributable to the plate

In the vast majority of dogs, the plate is never removed. It remains in place for life with no adverse effects.

Myth 5: "TPLO prevents arthritis"

The truth: TPLO reduces and slows arthritis progression. It does not prevent it. All CCL-affected stifles develop progressive OA regardless of surgical technique or outcome.

SustainableVet.org confirms: mild arthritis is expected even in successful cases.

Published long-term data (TPLO Info, citing long-term retrospective studies) confirms moderate but significant OA progression in all TPLO cohorts with follow-up extending to 6.8 years.

TPLO produces substantially less OA progression than TTA or lateral suture stabilization, but OA progression is universal.

The appropriate expectation: TPLO minimizes OA development and clinical impact. Long-term management (weight management, exercise modification, joint supplements, and periodic NSAID use for flares) is required in all TPLO dogs.

Myth 6: "Dogs are in severe pain after TPLO"

The truth: modern veterinary anesthesia and pain management protocols produce well-controlled post-operative pain in TPLO dogs. Dogs typically begin bearing some weight within 24 to 48 hours. Pain that is not controlled is a clinical problem requiring medication adjustment -- not an expected feature of TPLO recovery.

SustainableVet.org confirms: it is a misconception that dogs experience severe pain after TPLO surgery; modern multi-modal pain management controls post-surgical pain effectively.

Post-operative pain management typically includes: NSAIDs (carprofen, meloxicam), gabapentin, opioids during hospitalization, local anesthetic nerve blocks at surgery.

Dogs in adequate pain control rest comfortably, bear some weight within days, and show appetite by day 3.

Uncontrolled post-operative pain (dog cannot settle, crying, refuses all weight bearing beyond day 3) indicates a need for pain medication adjustment -- contact your vet rather than accepting it as inevitable.

Myth 7: "TPLO is too risky for most dogs"

The truth: TPLO has a 90 to 95% success rate. The complication rate across all studies is 10 to 34%, but the vast majority of complications are minor (superficial infection, seroma, mild swelling). Serious complications requiring revision surgery occur in fewer than 10% of cases.

Dispomed confirms: overall complication rates are 14 to 34%, but a second surgery is required in less than 10% of cases.

No surgery is without risk.

But for a dog with a torn CCL, the risk of TPLO is substantially lower than the certainty of progressive joint deterioration, pain, and reduced quality of life without surgical treatment.

Myth 8: "TPLO is only for show dogs or working dogs"

The truth: TPLO is appropriate for any dog with CCL rupture that will benefit from restored joint stability -- including middle-aged household pets with no competitive goals.

SustainableVet.org confirms: some pet owners mistakenly believe that TPLO surgery is only for show dogs or high-performance athletes; this is not true; TPLO benefits any dog with CCL disease.

The goal of TPLO is freedom from joint pain and restored ability to perform normal daily activities -- walking, playing, using stairs, sitting and rising comfortably.

These are benefits for every dog, not just sport dogs.

Myth 9: "All dogs with CCL tears need TPLO immediately"

The truth: TPLO is not always an emergency. The timing of surgery should be guided by the veterinary assessment. Partial tears in small dogs may be monitored with conservative management. Dogs with significant concurrent illness may benefit from medical optimization before surgery. The appropriate goal is surgical timing that optimizes anesthetic risk and surgical conditions, not surgical urgency at any cost.

SustainableVet.org confirms: while TPLO surgery is the best treatment for CCL tears, it isn't necessary for every case; for mild or partial tears in less active dogs, alternatives can be effective.

However, in dogs with complete rupture, particularly larger breeds, delay generally produces worse outcomes as OA progresses and the meniscus is exposed to ongoing mechanical insult from the unstable joint.

Myth 10: "If TPLO fails, the dog will never recover"

The truth: most TPLO complications are treatable. Superficial infections resolve with antibiotics. Late meniscal tears are treated with partial meniscectomy. Implant failures can be revised. Osteomyelitis, the most challenging complication, requires prolonged treatment but is often successfully managed.

SustainableVet.org confirms: revision TPLO surgery can be performed if the initial procedure fails; this may involve removing or replacing implants, repositioning the tibial cut, or addressing infections.

The critical factor in outcome from a complication is early detection and prompt treatment. Most complications that are identified and treated early resolve without long-term sequelae.

Frequently asked questions

Is TPLO actually the best treatment for CCL rupture?

For most dogs over 15 to 20 kg, TPLO is the most evidence-supported surgical option, producing the highest rates of long-term function and owner satisfaction in the published literature.

For small dogs, lateral suture stabilization achieves comparable results at lower cost. The choice depends on the individual dog's size, activity level, TPA, and health status.

Can I wait and see how my dog does without surgery?

You can choose conservative management.

The expected outcome in most dogs over 15 kg with complete CCL rupture who do not have surgery is progressive lameness, rapidly advancing OA, ongoing meniscal damage, and reduced quality of life.

Early surgical intervention consistently produces better long-term outcomes than delayed or non-surgical management.

Is the recovery really as strict as described?

Yes. The restriction protocol exists because the plate holds the osteotomy until new bone consolidates -- a process that takes 8 to 12 weeks regardless of how well the dog appears.

A single running or jumping episode before healing is confirmed can displace the plate and require revision surgery.

Will my dog be the same dog after TPLO?

Most owners report their dog is effectively the same dog -- or better than before the CCL rupture -- within 6 to 12 months of surgery.

The 90 to 95% success rate reflects a high proportion of dogs returning to their previous activity level.

Some dogs develop mild age-related stiffness years later as OA progresses, but this is manageable with appropriate care.

Does TPLO cure the CCL problem permanently?

TPLO permanently corrects the biomechanical cause of CCL-related instability in the operated stifle. It does not repair or replace the CCL -- it makes the CCL unnecessary.

It does not prevent CCL disease in the contralateral stifle.

TPLO has a high overall success rate, but complications do occur. The published overall complication rate ranges from 10 to 34%, with most complications being minor and manageable.

Knowing what to watch for -- and when a sign requires a same-day call vs. a mention at the next scheduled appointment -- allows owners to respond appropriately.

Quick answer: The 15 most common post-TPLO complications: surgical site infection, seroma, implant loosening or failure, osteomyelitis, late meniscal tear, tibial tuberosity fracture, delayed bone healing, persistent lameness, non-union, intra-articular screw placement, nerve damage, patellar tendon thickening, patellar luxation, progressive osteoarthritis, and contralateral CCL rupture. Most are minor and manageable.

Key takeaways

• The overall complication rate is 10 to 34%: most complications are minor (swelling, mild infection); serious complications such as implant failure or osteomyelitis are less common
• SSI is the most frequent single complication: reported in 2.9% to 17.3% of TPLO procedures; most are superficial and treatable with antibiotics if caught early
• Late meniscal tear occurs in 1.8% to 10.5% of cases where the meniscus was normal at surgery; it presents as sudden lameness return with meniscal click
• Tibial tuberosity fracture is reported in 1 to 9% of TPLO cases: incorrect positioning and oversized saw blades are the main risk factors
• Implant-associated infection occurred in 3.4% and osteomyelitis in 0.6% across numerous studies; osteomyelitis requires strong antibiotics for 4 to 6 months and sometimes plate removal
• Contralateral CCL rupture is a significant long-term risk: 30 to 40% of dogs develop rupture of the opposite CCL; owners should monitor the opposite stifle

Early complications (weeks 0 to 8)

1. Surgical site infection (SSI)

The most common complication. SSI ranges from superficial incisional infection (treatable with oral antibiotics and wound care) to deep implant-associated infection requiring plate removal.

Signs: redness spreading beyond the incision, warmth, swelling, cloudy or malodorous discharge.

Incidence: 2.9% to 17.3% per published literature; the PMC 769-TPLO study (769 procedures) found 8.5%.

Management: culture-directed antibiotics for superficial infections; surgical debridement and sometimes plate removal for deep implant infections.

2. Seroma

A localized collection of clear serous fluid under the skin near the incision, typically appearing 1 to 3 weeks post-surgery.

Signs: soft, fluctuant swelling at or near the incision; no warmth or redness; clear fluid if aspirated.

Incidence: common; most resolve without treatment.

Management: monitoring; aspiration if large or causing discomfort; bandaging in some cases.

3. Acute lameness from overactivity

The dog is over-active during the restriction period and bears too much load on the plate before the osteotomy heals.

Signs: sudden worsening of lameness after a period of improvement; may indicate implant stress or early failure.

Management: strict crate rest; radiographic assessment to rule out implant displacement.

4. Wound dehiscence

The incision edges separate before fully healing. More common in dogs that lick the incision despite an e-collar that fits incorrectly.

Signs: open wound edges, sometimes with tissue visible.

Management: cleaning and re-closure in most cases; e-collar compliance review.

Mid-term complications (weeks 4 to 16)

5. Delayed bone healing

The osteotomy is not showing expected consolidation on radiographs at the 6 to 8 week checkpoint.

Signs: radiographic evidence of widening osteotomy gap or absence of callus formation; may or may not produce clinical signs.

Risk factors: infection, excessive activity, poor bone quality (older dogs, large breeds), NSAIDs at high doses for extended periods.

Management: extended activity restriction; investigate for underlying infection; nutritional support.

6. Tibial tuberosity fracture

A fracture of the tibial tuberosity (the prominence where the patellar tendon attaches) caused by the osteotomy saw blade coming too close to this structure.

Incidence: 1 to 9% per Laguna Woods Vets; higher in dogs with high TPA, high body weight, and large TPA change.

Signs: acute severe lameness; radiographic evidence of fracture.

Management: surgical repair or conservative management depending on displacement.

7. Late meniscal tear

A meniscal tear occurring after TPLO in a meniscus that appeared normal at surgery. See the dedicated meniscal tear article for full detail.

Incidence: 1.8% to 10.5% of cases with normal meniscus at TPLO (Dog Discoveries).

Signs: sudden lameness regression; meniscal click on movement; pain on stifle manipulation.

Management: partial meniscectomy.

8. Implant loosening or failure

The plate or screws shift, bend, or break -- typically from premature overactivity before the osteotomy heals.

Signs: sudden severe lameness; pain at plate site; radiographic evidence of screw loosening, plate migration, or osteotomy displacement.

Management: revision surgery in most cases of significant displacement.

Long-term complications (months 3 and beyond)

9. Osteomyelitis

Bone infection extending from a superficial SSI or introduced via hematogenous seeding. Difficult to treat.

Incidence: 0.6% per Dog Discoveries citing multiple studies.

Signs: persistent lameness; draining tract; radiographic bone destruction, periosteal reaction, or sequestrum.

Management: Laguna Woods Vets confirms osteomyelitis requires strong antibiotics for 4 to 6 months; a wound culture aids antibiotic selection; plate removal is often required.

10. Non-union

The osteotomy fails to heal, resulting in permanent instability at the cut site.

Risk factors: infection, inadequate fixation, excessive motion, poor blood supply.

Signs: persistent lameness; radiographic evidence of osteotomy gap persisting beyond 16 weeks with no bridging callus.

Management: revision surgery, bone grafting, and often implant revision.

11. Intra-articular screw placement

A screw tip violates the joint space, causing joint damage and persistent pain. Best identified on the postoperative radiograph.

Signs: ongoing lameness; pain on stifle range of motion; radiographic evidence of screw in joint space.

Management: removal of the offending screw.

12. Persistent lameness without identifiable cause

Some dogs have persistent mild lameness despite uncomplicated bone healing and no identifiable complication. This may reflect residual arthritis progression, muscle atrophy, or subclinical meniscal issues.

Management: rehabilitation, joint supplements, and management of secondary osteoarthritis.

13. Patellar tendon thickening

Fibrous thickening of the patellar tendon develops in some TPLO dogs over time. This is typically not clinically significant.

Signs: palpable thickening of the patellar tendon on examination; usually incidental finding.

Management: generally none required; physiotherapy in some cases.

14. Patellar luxation

Medial patellar luxation can develop or worsen after TPLO, particularly if the plate is contoured in a way that affects patellar tracking.

Signs: intermittent lameness, popping of the patella medially on examination.

Management: surgical correction (trochleoplasty and tibial crest transposition) in symptomatic cases.

15. Progressive osteoarthritis

All dogs with CCL disease develop some arthritis progression regardless of surgical technique. TPLO slows but does not stop this process.

Signs: gradual stiffness, lameness that is worse after rest, reduced activity tolerance.

Management: joint supplements (omega-3 fatty acids, glucosamine), weight management, NSAIDs for flares, hydrotherapy.

Contralateral CCL rupture: a special consideration

Contralateral CCL rupture is not a complication of TPLO but deserves mention.

Midvalley Animal Clinic confirms it is very common (30 to 40% of patients) for both knees to develop this ligament injury.

Owners of dogs that have had unilateral TPLO should monitor the opposite stifle for early signs.

Frequently asked questions

What is the most common serious complication after TPLO?

Deep implant-associated infection requiring plate removal is the most common serious complication, with an implant removal rate of 3.5 to 7.5% of procedures (ResearchGate).

Osteomyelitis (0.6%) and tibial tuberosity fracture (1 to 9%) are other serious but less common complications.

Is a 10 to 34% complication rate high for an orthopedic surgery?

The range is real but the majority of complications are minor -- a seroma, mild superficial infection treated with antibiotics, or a brief period of increased lameness.

Serious complications requiring revision surgery are significantly less common. TPLO's overall success rate (93% limb function restoration at 1 year per a 2013 study) reflects that most dogs recover well.

Can complications be prevented?

Most can be reduced in risk but not eliminated.

Owner-controlled risk reduction: e-collar compliance, strict activity restriction for 8 to 12 weeks, daily incision inspection, and attending all scheduled vet appointments.

What happens if my dog develops two complications simultaneously?

This is uncommon but does occur (for example, SSI leading to delayed bone healing). Management is coordinated by your surgical team based on the severity and interaction of the complications.

Contact your vet immediately for any concern.

Should I be worried every time my dog limps?

A degree of lameness is expected throughout the recovery period. The key signal is trajectory: steadily improving lameness is expected; suddenly worsening or reversed lameness is not.

Monitor for any sudden changes and contact your vet for trajectory reversals.

TPLO recovery is a structured, staged process. The surgery corrects the mechanical cause of CCL instability, but the bone, soft tissue, and muscle need weeks to months to rebuild around that correction.

Understanding what is required at each stage -- and what signs require prompt veterinary contact -- is as important as the surgery itself.

Quick answer: Post-TPLO recovery requires 8 to 12 weeks of structured activity restriction for bone healing, followed by progressive rehabilitation. Key milestones: 2-week incision recheck; 6-week radiographic assessment; 12-week final radiograph and activity clearance. Warning signs requiring same-day contact: sudden non-weight bearing, spreading redness or discharge, fever, or worsening lameness.

Key takeaways

• The first 2 weeks are the most critical: the osteotomy has no mechanical strength; jumping, running, or slipping can displace the plate; crate rest with bathroom leash walks only is non-negotiable
• Most dogs begin toe-touching within 24 to 48 hours of surgery: early weight bearing maintains muscle mass and stimulates bone healing; it does not indicate readiness for more activity
• Cold therapy for the first 3 to 5 days significantly reduces swelling and pain: 10 to 15 minutes of wrapped ice pack applied 3 to 4 times daily is the most effective owner-administered early intervention
• The 6-week radiograph is the gate for activity increase: bone healing cannot be confirmed clinically; radiographic assessment is the only reliable confirmation of osteotomy progression
• Full muscle recovery takes 4 to 6 months: bone healing at 12 weeks and full functional recovery are different endpoints
• Reducing food intake by approximately 30% during recovery prevents weight gain that stresses the healing osteotomy; activity restriction rapidly leads to weight gain without dietary adjustment

Immediate post-operative period: the first 24 to 48 hours

Coming home

Most dogs are discharged 24 to 48 hours after TPLO, though same-day discharge protocols exist at some facilities.

The dog will be sedated, disoriented from anesthesia, and may have bandaging on the surgical leg. Expect:

• Grogginess and disorientation for 12 to 24 hours from anesthesia
• Some whining or restlessness (often anesthesia effect, not pain)
• Refusal to bear weight or toe-touching only
• Mild to moderate swelling around the incision, peaking at days 2 to 5

Setting up the recovery space

Before the dog arrives home, have in place:

• A correctly sized crate in the main living area
• Non-slip mats or yoga mats over all hard flooring
• Soft, washable bedding in the crate
• Water and food at floor level
• Baby gates blocking stairs
• Medications filled and ready

Medications: first day priorities

Give prescribed medications on the schedule provided at discharge. NSAIDs (meloxicam, carprofen) require food. Gabapentin causes sedation -- this is expected and helps with pain and anxiety in the first days.

Never skip doses or give extra without veterinary guidance.

Week-by-week recovery overview

Weeks 1 to 2: incision healing phase

Activity: crate rest except for bathroom leash walks. Maximum 5-minute walks, 3 to 5 times daily. No stairs, no furniture, no running, no off-leash time.

E-collar: must be worn at all times except supervised eating. One licking episode can introduce S. pseudintermedius from the oral cavity directly into the incision.

Cold therapy: wrap an ice pack in a thin cloth; apply to the incision for 10 to 15 minutes; 3 to 4 times daily; begin day 1 and continue through days 3 to 5.

Incision inspection: check the incision daily at a consistent time. Normal healing: redness fading from day 5, no discharge after day 3, clean approximated wound edges. Concerning: spreading redness, cloudy or malodorous discharge, wound dehiscence.

Weight management: Medcovet recommends reducing food intake by approximately 30% during the restriction period to prevent weight gain from inactivity.

2-week recheck: incision assessment, suture or staple removal if healing is confirmed, pain management review, early mobility assessment.

Weeks 3 to 6: progressive walking phase

Activity: leash walk duration increases -- by up to 5 minutes per week from the week 2 baseline. No off-leash, no running, no stairs without guidance.

Passive range-of-motion exercises: if the vet has approved, begin gentle flexion and extension of the stifle. 5 to 10 repetitions, 2 to 3 times daily. Prevents stiffness during the bone healing period.

Weight bearing: most dogs should be consistently bearing weight on the operated leg by weeks 3 to 4. Three-legged walking during activity is still common but should be decreasing.

Diet: maintain the reduced caloric intake until the vet clears increased activity.

Weeks 6 to 8: radiographic checkpoint

6-week radiograph: the single most important post-operative checkpoint. Images confirm whether the osteotomy is healing as expected. If healing is progressing, activity is increased. If healing is delayed, restrictions continue and the underlying cause is investigated.

After radiographic confirmation:

• Leash walks increase to 15 to 20 minutes
• Physiotherapy begins
• Controlled hill walking and balance work may begin

SustainableVet.org confirms: after the initial weeks of rest, swelling should decrease; gradual increase in leash walking should follow; physical therapy options include hydrotherapy, balance training, laser therapy, and massage.

Weeks 8 to 12: consolidation

10 to 12 week radiograph: confirms bone union. After radiographic confirmation of healing, activity restrictions are progressively lifted.

Return to activity: activity is reintroduced progressively over the following 4 to 6 weeks. No sudden full return to prior activity level.

Managing common post-operative issues

Swelling

Expected: peaks at days 2 to 5, resolves by 2 weeks. Ankle swelling from gravity-dependent fluid migration is normal at days 3 to 5.

Concerning: swelling that is not reducing after day 5, or that reappears after initial resolution.

Management: cold therapy in the first 3 to 5 days; elevation where possible; contact vet if swelling is not following the expected trajectory.

Pain and restlessness

Normal pain is controlled by the prescribed medication regimen and should consistently decrease over the first 2 weeks.

Uncontrolled pain (unable to settle, continuous crying, refusing all weight bearing beyond day 3) requires a vet call -- medication adjustment or a complication evaluation is needed.

Incision care

Do not clean the incision daily unless specifically instructed by your vet. Daily inspection is required; daily cleaning is not. If cleaning is needed, use only the vet-approved solution.

Constipation

Opioid pain medications commonly cause constipation in the first days. Discuss this with your vet at discharge -- they may recommend a stool softener if constipation becomes a concern.

Warning signs that require same-day veterinary contact

• Sudden complete non-weight bearing after a period of partial bearing
• Spreading redness beyond the incision margins
• Cloudy, yellow, green, or malodorous discharge from the incision
• Wound edges separating
• Fever (rectal temperature above 39.5 C / 103.1 F)
• Lameness worsening after a period of improvement (trajectory reversal)
• New swelling at the plate site (not the incision) after the second week
• Any systemic sign (lethargy, inappetence, fever) accompanying local wound changes

Frequently asked questions

My dog is not using the leg at all 5 days after surgery. Is this normal?

Some dogs refuse to bear weight for the full first 2 weeks -- this is within the normal range.

If the dog was bearing some weight at days 2 to 3 and has now stopped completely, or shows signs of severe pain, contact your vet to rule out a complication.

Persistent non-weight bearing beyond 2 weeks warrants assessment.

When can my dog go back to sleeping in our bed?

Not during the restriction period. Jumping off the bed -- even once -- generates the same plate-failure risk as running.

The dog must sleep in the crate or on a floor-level dog bed for the full restriction period.

My dog is constantly trying to lick the incision. What can I do?

Ensure the e-collar is the correct size -- most dogs can reach their hind legs with a collar that is too small.

Try a longer cone or a recovery suit (medical pet shirt) as a supplement. Ask your vet about trazodone or gabapentin for anxiety driving the licking behavior.

Do not remove the e-collar to give the dog a break unless you are directly supervising and can prevent licking.

Can I give my dog human joint supplements during recovery?

Some human supplements (fish oil at appropriate doses) are safe. Others contain xylitol or other ingredients toxic to dogs. Never give a human supplement without explicit vet approval.

Veterinary-formulated joint supplements are the safer choice.

How do I know when recovery is complete?

Recovery is complete when: (a) the 12-week radiograph confirms bone union, (b) the vet clears full activity, and (c) the operated leg has regained near-symmetrical muscle mass (4 to 6 months).

Bone healing at 12 weeks is the legal clearance; full muscle recovery is the functional completion of recovery.
