Returning an agility dog to sport after TPLO surgery requires more than standard recovery. The standard 8 to 12 week bone healing protocol restores a dog to normal household function.

Returning to agility -- a high-impact sport involving jumping, sharp turns, weave poles, and contact obstacles -- requires a further 4 to 6 months of structured conditioning on top of that foundation.

Quick answer: Most agility dogs return to training 7 to 9 months post-TPLO. The Balanced Dog confirms 80% returned before 9 months (average 7.5 months). Bone healing at 8 to 12 weeks is the starting point. Return to sport requires muscle symmetry, pain-free movement, and a graduated protocol with vet clearance.

Key takeaways

• The return-to-agility timeline averages 7 to 9 months: The Balanced Dog confirms 80% returned before 9 months, average 7.5 months; 3 to 6 months reflects light training, not full competition
• Bone healing at 8 to 12 weeks is the starting point, not the endpoint: high-impact agility may require 4 to 6 more months; healed bone does not mean rebuilt muscle
• Agility-specific demands require agility-specific conditioning: jumping, tight turns, weave poles, and contacts generate forces far greater than walking; the dog must be conditioned for these before returning
• All dogs with agility return goals need a return-to-sport protocol: it adds sport-specific movement, progressive jumping, and fitness benchmarks beyond the standard recovery protocol
• Veterinary clearance at each phase is non-negotiable: vet or surgeon clearance is required before resuming training; no benchmark should be self-assessed
• Not all dogs will reach pre-surgery performance: most regain significant function but some need training changes to reduce joint stress

Why agility is a higher bar than normal recovery

Normal TPLO recovery targets return to household mobility: walking, light running, stairs, and play. Agility sport involves:

• Jumping: impact forces on landing of 2 to 3 times body weight
• Tight turns at speed: high lateral shear forces on the stifle
• Weave poles: rapid lateral flexion and extension
• Contact obstacles (A-frame, dog walk, teeter): climbing and controlled descent under dynamic loading

Each of these demands requires not just healed bone but fully rebuilt muscle, coordinated neuromuscular control, and joint proprioception. These take months to restore after TPLO.

SustainableVet.org confirms: dogs in sports or agility should reintroduce jumps and running only after veterinary clearance; swimming or uphill walking maintains muscle tone during the conditioning phase.

The return-to-sport timeline

Phase 1: bone healing (weeks 0 to 12)

Standard TPLO recovery. Strict confinement, graduated leash walking, and passive range-of-motion exercises. No running, jumping, or agility activity of any kind.

Radiographic bone healing is confirmed at the 8 to 12 week recheck. This is the gate that opens Phase 2.

Phase 2: rebuilding foundation fitness (months 3 to 5)

After bone healing is confirmed, the focus shifts to rebuilding the muscle mass and neuromuscular coordination that atrophied during the restriction period.

Activities during Phase 2:

• Progressive leash walking with duration increasing weekly
• Hydrotherapy (underwater treadmill) for muscle building without joint impact
• Hill walking (controlled inclines) to load the hip extensors and stifle stabilizers
• Balance and proprioception work (wobble boards, cavaletti poles)
• Core strengthening exercises

TPLO Info confirms: overall return to agility takes around 3 to 6 months; this period of rebuilding is what fills the gap between bone healing and sport re-entry.

Phase 3: sport-specific conditioning (months 5 to 7)

Once the dog has rebuilt baseline fitness, sport-specific conditioning begins. This is distinct from the standard recovery protocol.

Activities:

• Controlled jumping starting very low (4 inches for a dog that jumps 24 inches in competition) and increasing progressively over 6 to 8 weeks
• Slow figure-8 work and curved running to restore stifle lateral mechanics
• Individual weave pole work at slow speed before full weave sequence
• Contact obstacle approach and exit work at slow, controlled speed
• Video gait assessment to identify any asymmetry or compensation patterns

Petcarepartners.co confirms: most vets suggest a waiting period of 4 to 6 months for running and fetch; for agility, add a further structured sport-specific phase on top of this.

Phase 4: return to full competition (months 7 to 9+)

Full competition resumption follows veterinary clearance of the sport-specific conditioning phase. The criteria for clearance include:

• Pain-free movement through full range of stifle motion
• Muscle symmetry (thigh circumference equal bilaterally)
• Confident single-leg weight bearing during agility-specific movements
• No lameness following a full practice session
• Surgeon clearance based on physical and radiographic assessment

The Balanced Dog confirms: it typically takes 7 to 9 months to return to sport; 80% of dogs returned to agility before 9 months with a good rehabilitation and return-to-sport program.

Factors that affect the return timeline

Dog's age: younger dogs (under 4 years) typically rebuild muscle faster than older dogs. Senior dogs may take 10 to 12 months or longer.

Dog's pre-surgical fitness: well-conditioned sport dogs with strong baseline muscle mass rebuild faster than deconditioned dogs. Body condition score at the time of surgery matters.

Adherence to the restriction protocol: dogs that were overactive during weeks 1 to 6 may have developed micro-complications or delayed healing that shifts the timeline.

Concurrent meniscal tear: dogs that had a meniscal tear treated at the time of TPLO may need additional time, particularly if a late meniscal tear occurs during the return-to-sport phase.

Bilateral CCL disease: dogs with CCL rupture on the second side during or after recovery for the first require the full protocol on the second side before bilateral agility work resumes.

SustainableVet.org confirms: average recovery time to agility is about seven months; some dogs start controlled activity at six months, while others take up to two years.

Using a certified canine rehabilitation therapist

For agility dogs, professional rehabilitation is strongly recommended rather than a home-only protocol. Certified canine rehabilitation practitioners (CCRPs) provide:

• Biomechanical gait analysis to detect compensatory movement patterns before return to sport
• Underwater treadmill protocols calibrated to the specific demands of agility
• Sport-specific functional testing to determine readiness
• Individualized return-to-sport programs

The Balanced Dog confirms: surgery is just the start; a good-quality rehabilitation and return-to-sport program is instrumental in giving the dog the best chance at returning to competitive agility.

Frequently asked questions

My agility dog had TPLO 6 months ago and is moving well. Can she start jumping?

Six months is within the average return-to-sport window but requires veterinary assessment before starting jumping.

The criteria -- muscle symmetry, pain-free full range of motion, confident single-leg weight bearing -- must be met and confirmed by your vet or rehabilitation therapist before any jumping begins.

Do not self-assess readiness.

Will my dog ever compete at the same level as before TPLO?

Many dogs do return to pre-injury competitive levels, especially those with strong pre-surgical conditioning and an excellent rehabilitation program.

SustainableVet.org confirms most dogs regain significant function and can participate in agility, though not all will reach pre-injury performance levels. The Balanced Dog study confirms 80% returned before 9 months.

Should I lower my dog's jump height after TPLO?

Discuss with your vet. Some dogs perform best at a jump height one level below their pre-surgery height to reduce cumulative joint loading. Others return to their full height without adjustment.

This is an individual decision based on the dog's age, size, arthritis level, and post-recovery movement quality.

Can I use a FitPaws or conditioning equipment at home?

Yes -- proprioception and balance equipment (wobble boards, FitPaws equipment, balance pads) is appropriate during Phase 2 and Phase 3 under the direction of your rehabilitation therapist.

These tools help rebuild the neuromuscular coordination needed for agility-specific movements. Always use on non-slip flooring.

What happens if my dog tears the other CCL during agility return?

Bilateral CCL disease is common (30 to 40% of dogs develop it). If the second stifle becomes symptomatic during the return-to-agility phase, the rehabilitation program pauses and the second stifle is assessed.

The return-to-agility timeline resets based on the second surgery date. Most dogs with bilateral TPLO can still return to agility.

Physical therapy after TPLO begins on day one -- not after the bone heals. The question is not whether to start, but which type is appropriate at each stage.

Early rehabilitation is about pain management and encouraging weight bearing. Later rehabilitation is about restoring muscle mass, range of motion, and functional strength.

The timing for each phase is defined by healing biology, not by how the dog appears to feel.

Quick answer: Physical therapy begins on day 1 with leash walks and cold therapy. Passive range-of-motion exercises start at days 3 to 5. Hydrotherapy begins at weeks 2 to 3. Strengthening increases from weeks 4 to 8. Plans complete by weeks 8 to 12; full recovery takes 4 to 6 months after TPLO surgery.

Key takeaways

• Leash walking begins within 24 hours of surgery: TPLO Info confirms short 5-minute walks multiple times daily from day 1; early weight bearing maintains muscle mass and bone healing
• Passive range-of-motion exercises start at days 3 to 5: gentle manual flexion and extension of the stifle maintains joint mobility during restricted activity
• Hydrotherapy can begin around weeks 2 to 3 after incision healing is confirmed; underwater treadmill provides resistance and buoyancy simultaneously
• Professional rehabilitation offers advantages over at-home protocols: certified therapists provide therapeutic laser, TENS, underwater treadmill, and individualized monitoring
• Strengthening exercises begin around weeks 3 to 4 when the dog consistently bears weight; cavaletti poles, weight-shifting, and balance work rebuild lost muscle
• Free running and high-impact activities resume only after radiographic bone healing confirmation at weeks 8 to 12; earlier return risks osteotomy failure

Phase 1: immediate post-surgical period (days 1 to 14)

What begins immediately

Leash walking: begins within 24 hours of surgery. TPLO Info confirms short 5-minute leash walks multiple times daily from day one. These walks are bathroom trips only in the first week -- not exercise walks. The goal is to maintain the neural stimulus for weight bearing and to prevent the complete disuse that leads to rapid muscle atrophy.

Veterinary Partner VIN confirms: Phase 1 begins immediately after surgery; slow, controlled leash walks 3 to 4 times daily for 5 to 10 minutes are the primary activity.

Cold therapy (icing): ice applied to the incision site for 10 to 15 minutes after each walk during the first 3 to 5 days. TPLO Info recommends icing the incision directly for the first 3 to 5 days post-surgery. Cold therapy reduces local inflammation and pain, making the dog more comfortable and more likely to bear weight.

Edmonton Veterinary TPLO protocol confirms: time physical therapy exercises approximately 30 minutes after pain medications are given so the dog is most comfortable during exercise.

Passive range-of-motion exercises (days 3 to 5)

PROM exercises are gentle manual flexion and extension of the stifle joint. SustainableVet.org confirms: gentle passive exercises usually start within 3 to 5 days post-surgery.

How to perform PROM:

• Hold the thigh and lower leg, not the joint itself
• Slowly flex the stifle toward the chest (as far as comfortable without resistance)
• Slowly extend the stifle toward straight
• 5 to 10 repetitions, 2 to 3 times daily
• Never force the range -- stop at the point of resistance or discomfort

PROM maintains joint cartilage health, prevents fibrous tissue formation in the joint, and maintains range of motion during the period when the dog is resting.

Phase 2: early rehabilitation (weeks 2 to 4)

What begins at the 2-week recheck

The 2-week recheck confirms incision healing and reviews early recovery. If healing is proceeding normally, Phase 2 activities begin.

Increased leash walk duration: TPLO Info recommends increasing walk duration by up to 5 minutes per week from the 2-week baseline. Vetplayas confirms: by week 2, controlled leash walks should be extended to promote muscle strength and flexibility.

Hydrotherapy: SustainableVet.org and the Vetplayas recovery guide both confirm hydrotherapy can begin around week 2 to 3, once the incision is healed. Underwater treadmill therapy provides three simultaneous benefits:

• Buoyancy reduces joint loading while still requiring weight bearing
• Water resistance builds muscle without impact
• Warmth promotes circulation and reduces stiffness

Professional hydrotherapy (certified facility with underwater treadmill) is preferable to open-water swimming in the early phase -- controlled depth and therapist supervision improve safety.

Balance training (from week 3 to 4): TPLO Info confirms that once the dog is consistently bearing weight on the operated leg (typically around weeks 3 to 4), weight-shifting exercises can begin. Stand the dog on a non-slip surface and gently push the hindquarters from side to side -- the dog responds by shifting weight to maintain balance, which activates the hip stabilizers.

Phase 3: progressive strengthening (weeks 4 to 8)

Core strengthening and higher-level exercises

Veterinary Partner VIN confirms: Phase 2 (which overlaps with what most owners call weeks 3 to 8) involves core strengthening once sufficient basic strength is achieved.

Activities that begin in weeks 4 to 8 (vet-directed):

• Cavaletti poles: slow stepping over low poles placed on the ground; encourages deliberate limb placement and hip flexion
• Hill walking: gentle inclines on a leash (begin by week 6 in most protocols)
• Sit-to-stand exercises: transitions from sitting to standing strengthen hip extensors
• Balance board or wobble board exercises: builds proprioception and stabilizer strength

WM-Referrals TPLO physiotherapy protocol confirms: start hydrotherapy, cavaletti poles, and balance board work at week 6; progress to 30 to 40 minute walks by this phase.

6-week radiograph checkpoint: activity level in Phase 3 is calibrated against radiographic findings at the 6-week visit. If bone healing is progressing well, activities increase as above. If healing is delayed, Phase 3 activities are deferred.

Phase 4: return to function (weeks 8 to 12 and beyond)

Radiographic confirmation at 8 to 12 weeks

SustainableVet.org confirms: most structured plans complete within 8 to 12 weeks. By 4 to 6 months, most dogs regain full mobility including running and playing.

After the 12-week radiograph confirms bone healing:

• Progressive jogging on leash
• Longer off-leash exploration in controlled environments
• Return to normal activity for most dogs
• Athletes and working dogs continue structured rehab for 4 to 6 months

Professional rehabilitation vs. at-home protocols

When professional rehab is recommended

TPLO Info confirms: ideally every dog would follow up with a rehabilitation therapist so a doctor can develop an individualized protocol. Professional rehabilitation is particularly beneficial when:

• The dog is slow to bear weight
• Significant muscle atrophy is present at the 6-week recheck
• The dog is a working dog, sports dog, or agility competitor
• Progress has stalled at any phase of recovery

What professionals offer

Certified canine rehabilitation therapists (CCRPs) provide:

• Therapeutic laser (reduces inflammation, promotes tissue healing)
• Transcutaneous electrical nerve stimulation (TENS) for pain management
• Controlled underwater treadmill protocols
• Individualized exercise prescription based on daily assessment
• Early detection of complications (inappropriate gait patterns, asymmetric muscle development)

At-home protocols

At-home rehabilitation following the vet's guidelines is appropriate for most dogs.

The core elements -- short leash walks, PROM exercises, cold therapy, gradual activity increase, and balance work -- are all achievable at home with proper instruction.

For the recovery timeline overview, see what to expect after TPLO surgery in dogs. For PROM exercises specifically, see PROM exercises for dogs after TPLO surgery.

For range-of-motion exercises, see TPLO range-of-motion exercises for dogs. For rehab exercise detail, see TPLO rehab exercises for dogs.

Frequently asked questions

Can physical therapy start before the incision heals?

Yes -- the early elements (leash walking, cold therapy, and PROM exercises) begin before the incision is fully healed, typically from day 1 to 5 onward.

Hydrotherapy and balance work require incision healing confirmation, typically at the 2-week recheck.

Is professional physical therapy necessary for TPLO recovery?

Not strictly necessary for all dogs, but beneficial for those recovering slowly, those with significant muscle atrophy, and working or sport dogs. At-home protocols following vet instructions are appropriate for most dogs.

Professional rehab adds precision and advanced modalities.

How often should my dog have hydrotherapy sessions?

Typically 1 to 3 times per week during the active rehabilitation phase (weeks 2 to 8). Frequency depends on the dog's response, transportation constraints, and cost.

Each session's therapeutic benefit persists for several days, so daily hydrotherapy is not required.

What if my dog refuses to use the leg despite physical therapy?

Persistent non-weight-bearing beyond 3 to 4 weeks warrants veterinary investigation. Possible causes include inadequate pain control, implant complication, late meniscal tear, or infection.

Physical therapy cannot proceed normally until the underlying cause of non-weight-bearing is addressed.

Can I use a swimming pool at home for hydrotherapy?

Only with vet guidance and with the dog supervised at all times. Open water swimming is less controlled than an underwater treadmill.

Risks include the dog launching themselves off the pool edge (impact on landing), inability to control depth, and water contamination of the incision if not fully healed.

TPLO surgery is a major orthopedic procedure that requires careful preparation before surgery and structured management after.

The recovery period -- 8 to 12 weeks of graduated activity restriction, multiple vet visits, and daily wound monitoring -- is as important as the surgery itself.

Most owners who struggle with recovery do so because they underestimated what the post-operative period involves. This guide walks through every phase.

Quick answer: Before TPLO surgery: complete pre-surgical bloodwork, fast 8 to 12 hours, prepare a crate and non-slip mats, fill prescriptions. After TPLO: crate rest weeks 1 to 2, progressive walking weeks 2 to 6, radiographic assessment weeks 6 to 8, activity increase after healing. Muscle recovery takes 4 to 6 months.

Key takeaways

• The home environment must be set up before surgery day: crate, non-slip mats, baby gates, low bedding, and supplies must be in place before the dog arrives home
• Fasting is required before surgery: no food for 8 to 12 hours before general anesthesia; water rules vary by facility
• The first 2 weeks are the most critical and restrictive: no running, jumping, stairs, or off-leash activity; bathroom trips on a short leash only; incision checked daily
• Radiographic assessment at 6 to 8 weeks is the gate that controls activity increase: without imaging confirmation, activity must not increase; radiographs are the only reliable confirmation
• Food intake should be reduced by approximately 30% during recovery: activity restriction rapidly leads to weight gain; extra weight stresses the healing osteotomy
• Full muscle recovery takes 4 to 6 months after bone healing is confirmed: bone healing at 12 weeks and full functional recovery are different endpoints

Before surgery: preparation checklist

Medical preparation (weeks before surgery)

Pre-surgical examination and bloodwork: your vet will perform a full physical examination and order a complete blood count and blood chemistry panel. These confirm the dog can safely handle anesthesia and healing. Senior dogs or those with health conditions may need additional testing.

Medication review: tell your vet all current medications and supplements. NSAIDs, certain supplements, and some other drugs need to be stopped before surgery. Never discontinue a prescription medication without vet instruction.

Weight management: if your dog is overweight, weight reduction before surgery reduces anesthetic and surgical risk. Even a 5 to 10% body weight reduction before surgery is beneficial.

Pre-surgical bathing: bathe 1 to 2 days before surgery if you wish; post-surgical bathing is restricted for 10 to 14 days.

Home preparation (day before surgery)

The recovery space:

• Crate (correctly sized: stand, turn, lie comfortably, not pace) in the main family living area
• Non-slip mats or yoga mats over all hard flooring in the recovery area
• Soft, washable bedding in the crate
• Water and food bowls at floor level
• Baby gates on stairs
• All furniture inaccessible to prevent jumping

Supplies to have ready:

• E-collar (confirm with the surgical facility whether one will be provided)
• Ice pack or bag of frozen peas for cold therapy
• Sling or lifting harness for larger dogs
• Short leash (4 to 6 foot, not retractable)
• Medications filled at the pharmacy before surgery day

SustainableVet.org confirms: before your dog comes home, prepare a safe and quiet recovery space with a crate or small room, soft bedding, good airflow, and away from stairs or slippery floors.

Fasting

No food for 8 to 12 hours before surgery. Water rules vary by facility -- confirm with your vet. Give no food the morning of surgery even if the dog appears hungry.

Surgery day: what to expect

Drop-off: typically early morning. The dog is admitted, weighed, examined, and an IV catheter is placed. IV antibiotics are given before the incision.

The procedure: the surgeon makes a medial incision over the proximal tibia, performs a small arthrotomy to assess the meniscus, makes the curved osteotomy cut, rotates the tibial plateau to approximately 5 degrees, and secures the plate and screws. The wound is closed in layers.

Duration: typically 1.5 to 2 hours.

Post-surgical care: the dog spends several hours in recovery before discharge (same day at some facilities; overnight at others).

Discharge: written instructions for medications, wound care, activity restrictions, and follow-up appointments are provided.

After surgery: week-by-week recovery timeline

Weeks 1 to 2: acute post-surgical phase

Activity: crate rest at all times except bathroom trips. Leash walks of 5 minutes maximum, 3 to 5 times daily. No stairs, no furniture, no off-leash time.

Weight bearing: most dogs begin toe-touching within the first few days. Some do not bear weight for the full 2 weeks -- both presentations are within normal range.

Wound care: e-collar on at all times except supervised eating. Inspect the incision daily at the same time. No bathing or wet incision exposure.

Cold therapy: 10 to 15 minutes of ice pack (wrapped in cloth) applied to the incision, 3 to 4 times daily for the first 3 to 5 days.

Medications: NSAIDs and gabapentin on the exact prescribed schedule. Give NSAIDs with food.

SustainableVet.org confirms: the first two weeks focus on rest and healing; the dog stays confined; short controlled leash walks are for bathroom breaks; check the incision daily for redness, swelling, or discharge.

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

Weeks 3 to 6: graduated activity phase

Activity: leash walk duration increases progressively. TPLO Info recommends increasing by up to 5 minutes per week. No off-leash activity. No stairs without guidance. No playing with other pets.

Weight bearing: most dogs should be bearing increasing weight through the operated leg. Three-legged walking during activity is still common but should be decreasing.

Passive range-of-motion exercises: gentle flexion and extension of the stifle, 5 to 10 repetitions, 2 to 3 times daily if the vet has approved.

Veterinary Healthcare Associates confirms: weeks 3 to 4, swelling should decrease; gradual increase in leash walking; passive range-of-motion exercises may begin.

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

Weeks 6 to 8: radiographic checkpoint

6-week radiograph (critical): images confirm whether the osteotomy is healing as expected. If healing is progressing, activity can be increased. If healing is delayed, restrictions continue.

If healing is confirmed: leash walks increase to 15 to 20 minutes, physiotherapy begins, short controlled hill walking may begin.

If healing is delayed: investigate for infection or non-union; extend restrictions; consider additional diagnostics.

Veterinary Healthcare Associates confirms: weeks 5 to 6, recheck X-rays may be taken to evaluate healing; improvement in weight-bearing and stability should be evident.

Weeks 8 to 12: consolidation and return to activity

8 to 10 week radiograph (in many protocols): confirms continued healing progression.

12-week radiograph (final major milestone): confirms bone union before lifting restrictions. After this confirmation:

• Running and off-leash play can gradually resume
• Stairs without support
• Normal household access

Post-12-week activity return: progressive reintroduction of activity over the following 4 to 6 weeks rather than an immediate full return.

Animal Outpatient Surgery confirms: in the final phase, your dog can return to normal activity levels, including running, jumping, and playing; continue monitoring for discomfort and maintain a balanced exercise routine.

Long-term: months 3 to 6

Full muscle recovery takes 4 to 6 months after bone healing. During this period:

• Progressive strengthening continues
• Hydrotherapy, balance work, and controlled running rebuild the atrophied operated leg
• Joint supplements (omega-3 fatty acids, glucosamine) are typically started or continued
• Weight management remains critical

Most dogs reach 90 to 95% of pre-injury function by 6 months with a compliant recovery.

Frequently asked questions

How strict does the activity restriction need to be in the first 2 weeks?

Very strict. No exceptions for stairs, sofa access, running, jumping, or unsupervised time without confinement.

A single running or jumping episode in the first 2 weeks can displace the plate before the osteotomy has any mechanical strength.

The restriction is designed to protect a bone that cannot yet protect itself.

My dog is eating less and seems depressed after surgery. Is this normal?

Yes, in the first 3 to 5 days. Anesthesia, post-surgical pain, and opioid medications can reduce appetite and alter behavior.

If the dog is not eating at all by day 3 or shows signs of significant distress, contact your vet.

Most dogs gradually return to normal eating and behavior within the first week.

When can my dog go swimming after TPLO?

Controlled hydrotherapy (underwater treadmill) can begin after the incision is confirmed healed at the 2-week recheck. Open water swimming (lakes, rivers) is typically not recommended until after the 12-week radiographic clearance.

Confirm with your vet in both cases.

Should I put my dog on a diet during recovery?

Reduce caloric intake rather than switching to a formal diet. Medcovet recommends approximately 30% reduction in food intake during the restriction period to prevent weight gain from inactivity.

If your dog was already at an ideal weight, a modest reduction (10 to 20%) is appropriate. Discuss with your vet.

My dog seems completely fine at week 4 and is pulling on the leash. Should I increase activity?

No. Continue the restriction protocol until the 6-week radiograph confirms bone healing progression.

The dog feeling well at week 4 is a positive sign, but bone healing lags significantly behind the dog's perceived comfort.

Dogs routinely feel ready to run before the osteotomy is safe to run on.

TPLO incision infection is one of the most common complications after surgery. Most incision infections are preventable with consistent owner-managed wound care, and most are treatable when caught early.

The window between a superficial incision infection (treatable with antibiotics) and a deep implant infection (requiring surgical intervention) is measured in days -- which is why daily inspection is not optional.

Quick answer: Normal TPLO incision healing shows mild redness fading from day 5, no discharge after day 3, and a clean approximated incision line. Infection signs: spreading redness, increasing warmth, cloudy or malodorous discharge, swelling not resolving, wound edges separating, or lameness worsening. Prevention centers on e-collar compliance, dryness, and daily inspection.

Key takeaways

• Licking is the most common preventable cause of TPLO incision infection: the oral cavity carries S. pseudintermedius that can inoculate the incision; e-collar compliance for 10 to 14 days is the most protective owner action
• The distinction between normal healing and early infection is trajectory-based: mild redness and clear serum discharge are normal for 2 to 3 days; anything worsening from day 5 onward warrants veterinary attention
• Infection signs requiring a same-day call: spreading redness, yellow or green discharge, malodorous discharge, wound dehiscence, or systemic signs alongside local wound changes
• Keeping the incision dry is the second most important prevention measure: bacteria proliferate in moist environments; no bathing or wet-grass walks until incision healing is confirmed by the vet
• Daily inspection at the same time each day creates a baseline: daily comparison of today to yesterday reveals whether the incision is improving or worsening
• Most superficial incision infections resolve with oral antibiotics if treated promptly: treatment escalates significantly if deep implant involvement occurs; early action prevents this escalation

Normal TPLO incision healing: what to expect

Understanding normal healing is the prerequisite for recognizing abnormal changes.

Days 1 to 3: acute inflammatory phase

Normal: the incision is red, mildly swollen, and warm. A small amount of clear to pale yellow serum may seep from the wound edges. The swelling may extend slightly beyond the incision line.

Context: this is the inflammatory phase -- the biological response to surgical trauma. It is expected and appropriate.

Days 3 to 5: peak swelling subsides

Normal: redness should be fading. Swelling should begin to reduce. Any discharge should have stopped by day 3. The incision line should be approximated (edges together and not gaping).

Days 5 to 10: healing consolidation

Normal: redness is minimal or absent. No discharge. The incision line is dry and the skin edges are growing together. The dog may experience some surface itching as new skin forms.

Suture/staple removal: typically at 10 to 14 days. The vet confirms incision healing before removal.

Day 14 onward

Normal: incision is healed, sutures removed, skin intact. Mild surface discoloration (pink to pale) is normal for several weeks. No further discharge.

Signs of TPLO incision infection

Spreading redness (most concerning early sign)

Normal healing produces redness confined to the incision line (typically 1 to 2 mm on each side).

Infection produces redness that spreads outward from the incision -- a widening halo of red skin extending beyond the original margins.

SustainableVet.org confirms: redness that worsens, especially with pain or heat, often accompanies infection. Contact your vet the same day if spreading redness is observed.

Warmth that is increasing rather than decreasing

Mild warmth is normal in the first 3 to 5 days.

Warmth that is increasing at day 7 or beyond -- when normal healing produces cooling -- indicates ongoing active inflammation, typically from infection.

Discharge type and timing

• Clear serum for 24 to 48 hours: normal
• Any discharge after day 3: concerning
• Cloudy, yellow, or green discharge at any stage: infection until proven otherwise
• Malodorous discharge: infection; contact vet immediately

SustainableVet.org confirms: inspect the incision daily for redness, swelling, or discharge; yellow or green discharge is not normal and needs immediate attention.

Wound dehiscence

The incision edges separate, exposing subcutaneous tissue or deeper structures. Most often caused by licking, but can occur from excessive activity, suture reaction, or infection undermining the tissue.

SustainableVet.org (complications article) confirms: if stitches are removed too soon or dehiscence occurs, a vet should assess the wound immediately.

Swelling that is not resolving

Expected swelling peaks at days 2 to 5 and consistently resolves after that.

Swelling that is the same or larger at day 7 as it was at day 3 is not following the expected trajectory.

Systemic signs alongside local changes

Fever (rectal temperature above 39.5 C / 103.1 F), lethargy, reduced appetite, or behavioral changes accompanied by any local wound sign constitute an emergency call. These suggest the infection is systemic.

SustainableVet.org (redness article) confirms: systemic signs including fever, lethargy, or loss of appetite along with redness indicate the infection may be spreading; contact your vet immediately.

Prevention: the actions that matter most

1. E-collar compliance without exception

The e-collar prevents the single most common preventable cause of TPLO incision infection: licking. Even one licking episode directly inoculates the wound with oral bacteria.

SustainableVet.org confirms: even brief periods of licking can introduce bacteria; an Elizabethan collar or medical pet shirt should be used at all times until the incision fully heals.

The e-collar must be worn:

• During sleep
• Unsupervised periods in the crate
• Whenever the dog is not under direct eye contact with the owner

If the dog can reach the incision with the collar on, the collar is the wrong size -- contact the vet for a larger size.

2. Keep the incision dry

Moisture promotes bacterial growth and skin maceration at the incision edges. No bathing or submerging the leg until the vet confirms healing at the 2-week recheck.

During wet weather, minimize wet-grass time on outdoor bathroom trips. Pat the leg dry immediately if it gets wet.

SustainableVet.org confirms: keep the incision clean and dry; avoiding moisture reduces infection risks.

3. Daily incision inspection

Inspect the incision at a consistent time each day. Compare today directly to yesterday. The trajectory (better, same, worse) is more diagnostically useful than any single observation.

Inspection takes 30 seconds. Pick a time (e.g., after the evening bathroom walk) and make it routine.

4. Do not clean with unapproved solutions

Unless instructed by your vet, do not apply hydrogen peroxide, alcohol, iodine, or other antiseptics to the incision. These can damage healing tissue and delay closure.

If cleaning is needed, use the vet-approved solution (typically dilute chlorhexidine or sterile saline).

5. Clean bedding weekly

Bedding in contact with the incision area accumulates skin bacteria. Wash crate bedding weekly in hot water.

6. Hand hygiene before touching the wound

Wash hands before any wound inspection or dressing change. Human skin also carries bacteria capable of contaminating an open or healing incision.

Treatment

Superficial infection (SSI-S): oral culture-directed antibiotics for 2 to 4 weeks; wound cleaning; continued e-collar compliance; wound recheck in 3 to 5 days to confirm response.

Progressing or deep infection: surgical debridement; deep culture; IV or long-course oral antibiotics; imaging to assess implant involvement.

Implant-associated infection: see the dedicated TPLO plate infection guide. Treatment typically includes plate removal once the osteotomy has healed.

Frequently asked questions

My dog's incision looks red but the vet said it looks normal at the 2-week recheck. Should I still be worried?

If the vet examined the incision in person at 2 weeks and found it normal, trust that assessment. Post-recheck monitoring continues -- if the incision changes after the recheck, contact the vet.

A single normal exam does not guarantee no infection will develop later.

Can I tell the difference between a seroma and an infection at the incision?

Seromas are soft, fluctuant (fluid-filled), non-painful swellings without redness, warmth, or discharge. Infection produces warmth, redness, possible discharge, and pain. If you cannot clearly distinguish the two, contact your vet for assessment.

The incision looked fine yesterday but today there is yellow discharge. What do I do?

Call your vet the same day. Yellow discharge at any point after the first 2 to 3 days is concerning. Do not wait to see if it resolves.

Keep the e-collar on and do not apply any home remedies to the wound before the vet advises.

My dog keeps trying to lick the incision even with the e-collar. What else can I try?

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

A longer cone, a recovery suit (medical pet shirt), or a contact bandage over the incision site (applied by your vet) can supplement the collar.

Ask your vet about trazodone or gabapentin if anxiety is driving the licking behavior.

Does the incision need to be cleaned every day?

In most cases, no. Daily cleaning is not required and may introduce contamination or irritate healing tissue. Daily inspection is required.

Clean only if the vet specifically instructs it and with the approved solution only.

Some degree of lameness after TPLO surgery is expected. The surgery involves a bone cut and plate fixation, and the dog's leg needs weeks to heal.

The clinical challenge for owners is distinguishing between normal post-surgical lameness (which requires patience) and lameness that indicates a complication (which requires prompt veterinary attention).

The answer depends heavily on timing, trajectory, and accompanying signs.

Quick answer: Normal post-TPLO lameness should show consistent week-over-week improvement. The most common pathological causes are: surgical site infection, late meniscal tear, implant loosening, muscle atrophy, delayed bone healing, and progressive osteoarthritis. The key signal is trajectory reversal -- lameness worsening after improvement or failing to improve for 2 or more weeks.

Key takeaways

• Some lameness is normal throughout the first 8 to 12 weeks of TPLO recovery: mild limping that improves gradually over 6 to 12 weeks is typical; the key variable is trajectory
• Trajectory reversal is the key warning sign: lameness that worsens after improvement, or fails to improve for 2 or more consecutive weeks, warrants veterinary evaluation before the next appointment
• Late meniscal tear is a recognized cause of sudden lameness regression: recurrence of lameness after initial resolution can indicate meniscal injury; it occurs in 2 to 22% of TPLO cases
• Muscle atrophy is a commonly underappreciated cause of persistent lameness: the affected leg loses muscle mass during restriction; inadequate rehabilitation leaves an asymmetric gait
• Progressive osteoarthritis is the most common cause of chronic mild lameness starting months after surgery; TPLO slows but does not stop this process
• Implant failure and infection must be ruled out for lameness that is worsening or not responding to conservative management; radiographs and culture are required for diagnosis

Normal post-surgical lameness: what to expect

Week 1 to 2

Most dogs are significantly lame in the first 1 to 2 weeks. They may toe-touch only or hold the leg off the ground entirely.

This is the acute post-surgical inflammatory phase combined with the effects of anesthesia wearing off.

SustainableVet.org confirms: some lameness is expected after TPLO surgery, especially in the first few weeks; normal recovery lameness is mild limping that improves gradually over 6 to 12 weeks.

Week 2 to 6

Consistent improvement should be visible week over week. By week 4, most dogs should be bearing significant weight on the operated leg during slow walking.

Three-legged walking during activity is still common but should be decreasing.

Week 6 to 12

Most dogs should be consistently weight-bearing on the operated leg. By week 12, most are nearly normal for household activities.

Radiographic confirmation of bone healing at weeks 6 to 8 and 12 guides when activity can increase.

Pathological causes of post-TPLO lameness

1. Surgical site infection (SSI)

Timing: most commonly weeks 1 to 4, but can occur at any stage (including months later for deep implant-associated infections).

Mechanism: bacterial contamination of the incision or implant causes inflammation and pain at the plate site, which produces or worsens lameness.

Signs accompanying lameness: redness, warmth, swelling, or discharge at the incision or plate site.

Action required: same-day veterinary contact for any infection signs alongside lameness.

2. Late meniscal tear

Timing: typically weeks 4 to 12 post-surgery, though it can occur months later.

Mechanism: the meniscus, which may have been structurally weakened before surgery or had a small tear not detected at surgery, fails under load during the recovery period.

Signs accompanying lameness: audible or palpable meniscal click; pain on stifle manipulation; sudden lameness regression in a dog that had been improving.

Animal Outpatient Surgery confirms: if lameness resolves after TPLO and recurs at a later time, this can be an indication of meniscal injury.

Action required: veterinary evaluation within 24 to 48 hours; arthroscopy or arthrotomy for diagnosis and partial meniscectomy for treatment.

3. Implant loosening or failure

Timing: most common in the first 6 to 12 weeks when the osteotomy is still healing and the plate bears the full load. Can also occur later from chronic infection or late trauma.

Mechanism: excessive activity before the osteotomy heals applies forces that exceed the plate's tolerance; screws pull out or the plate bends.

Signs accompanying lameness: sudden severe lameness; pain at the plate site; sometimes audible clicking or grinding; radiographic evidence of screw loosening or plate migration.

SustainableVet.org confirms: signs of implant failure include ongoing limping, pain, swelling around the implant site, and unusual clicking or grinding sounds from the joint.

Action required: same-day emergency veterinary contact for sudden severe lameness; radiographs urgently required.

4. Muscle atrophy and weakness

Timing: most prominent from weeks 4 to 12; persists for months if rehabilitation is inadequate.

Mechanism: during activity restriction, the operated leg muscles (quadriceps, hamstrings, hip extensors) atrophy rapidly. Asymmetric muscle mass leads to asymmetric weight distribution and abnormal gait patterns that present as persistent limping.

Vetplayas confirms: limited mobility during recovery leads to muscle loss and decreased strength. This imbalance results in abnormal gait patterns and subsequent limping.

Signs: visible muscle asymmetry (operated thigh smaller than opposite); lameness that worsens with activity and improves with rest; no accompanying warmth, redness, or plate-site changes.

Action required: rehabilitation assessment; physiotherapy to rebuild muscle mass.

5. Delayed bone healing

Timing: identified at the 6 to 8 week radiographic assessment.

Mechanism: the osteotomy is not showing expected callus formation and cortical bridging. Common causes include infection, excessive activity, poor blood supply, or systemic factors (NSAIDs at high dose for extended periods, nutritional deficiencies).

Signs: persistent lameness at a level that does not match the expected trajectory; confirmed radiographically.

Action required: veterinary investigation for underlying cause; extended activity restriction; sometimes additional diagnostics (culture to rule out occult infection).

6. Delayed union or non-union

Timing: identified at 12+ weeks when bone healing should be complete.

Mechanism: the osteotomy fails to heal. The plate is subject to continued cyclic loading without the protection of consolidated bone, increasing implant failure risk.

Action required: specialist reassessment; may require bone grafting, implant revision, or extended medical management.

7. Progressive osteoarthritis

Timing: typically becomes clinically apparent after 6 to 12 months.

Mechanism: CCL disease initiates an irreversible arthritis process in the stifle. TPLO reduces but does not eliminate arthritis progression. Over months and years, arthritis produces chronic mild lameness, particularly after rest and exercise.

Signs: stiffness that improves with movement; lameness worse in cold weather or after long periods of rest; gradual worsening over months; bilateral involvement common.

SustainableVet.org (failure symptoms article) confirms: limping 2 years post-TPLO may result from arthritis, implant irritation, meniscal damage, or muscle atrophy.

Action required: long-term management (joint supplements, weight management, NSAIDs for flares, hydrotherapy, physiotherapy).

8. Contralateral CCL rupture

Timing: any time during or after recovery from the first TPLO.

Mechanism: the contralateral CCL, subject to the same degenerative process and bearing extra load during recovery, may rupture. The dog appears to start limping on the opposite leg.

Signs: what appears to be recovery from one side suddenly accompanied by new lameness on the opposite side; the dog may be lame on a different leg or bilateral.

Action required: veterinary evaluation; bilateral CCL disease may require staged or simultaneous bilateral TPLO.

How to assess the trajectory at home

Create a simple weekly log: note the leg-use pattern (full bearing, toe-touching, three-legged) and the dog's willingness to walk at each prescribed walk time.

Compare week 4 to week 3, week 6 to week 5. If the pattern is consistently improving, continue the protocol. If it is static or worsening, contact your vet.

Frequently asked questions

My dog was progressing well at week 4 but is limping more at week 5. What do I do?

A single week of regression after a period of progress is not necessarily pathological -- increased activity, weather changes, or an off day can cause temporary setbacks.

But if the worsening persists for 2 weeks, or is accompanied by any infection signs, contact your vet.

Monitor closely and reduce activity to the week 2 level for 24 to 48 hours to see if the leg settles.

My dog is still limping 4 months after TPLO surgery. Is this normal?

Mild residual lameness can persist to 4 months, particularly in older dogs or those with significant muscle atrophy.

However, lameness at 4 months that is not showing week-over-week improvement warrants a veterinary assessment.

A radiograph will confirm bone healing status; physical examination will assess muscle mass and stifle range of motion.

My dog is limping on the opposite leg during TPLO recovery. What does that mean?

This raises concern for contralateral CCL disease. The opposite leg is bearing extra load during recovery and may have already been compromised.

A new limp on the opposite leg during recovery warrants veterinary evaluation, including assessment and radiographs of the contralateral stifle.

Can physiotherapy reduce long-term limping?

Yes, significantly. Rebuilding the atrophied quadriceps and hip extensor muscles through controlled hydrotherapy, cavaletti exercises, and progressive strength work reduces the compensatory gait patterns that produce chronic post-TPLO lameness.

Weight management is equally important -- every additional kilogram of body weight increases stifle load.

When is limping after TPLO an emergency?

Sudden complete non-weight bearing (holding the leg entirely off the ground) after a period of normal improvement is an emergency call. Same-day emergency veterinary contact is appropriate for this presentation.

Gradual worsening that does not resolve within 24 to 48 hours is a next-day call.

A meniscal tear after TPLO surgery is one of the most recognized post-operative complications.

The medial meniscus is at risk both at the time of CCL rupture and after surgery, when residual instability or degenerative changes can damage tissue that appeared normal during the original procedure.

Recognizing the signs early significantly improves outcomes.

Quick answer: Post-TPLO meniscal tears present as sudden lameness return in a previously improving dog, often with a meniscal click. Late tears occur in 2 to 22% of TPLO cases (RCVS). PubMed found 5.6% late meniscal tear incidence. Treatment is partial meniscectomy; all dogs treated returned to peak limb function per PubMed.

Key takeaways

• Late meniscal tears occur in 2 to 22% of post-TPLO dogs: RCVS confirms this range; a PubMed TPLO arthroscopy study found a 5.6% late meniscal tear incidence
• The hallmark sign is sudden lameness regression in a previously improving dog: RCVS confirms affected dogs display good mobility and then go suddenly lame; this trajectory reversal distinguishes meniscal injury
• The meniscal click is audible but not always present: the absence of a click does not rule out meniscal injury
• The meniscus does not heal on its own: limited blood supply prevents natural regeneration; small tears may be managed conservatively but most require partial meniscectomy
• Partial meniscectomy produces excellent outcomes: all dogs treated by partial meniscectomy returned to peak limb function (PubMed); outcomes at 6 months are comparable to dogs with intact menisci
• Concurrent meniscal tears do not worsen long-term outcomes: AVMA research found similar midterm outcomes for TPLO plus meniscectomy vs TPLO alone, despite more severe arthritis at surgery

The medial meniscus: what it is and why it is at risk

The medial meniscus is a crescent-shaped fibrocartilage structure on the inner surface of the stifle joint. It distributes joint load, provides shock absorption, and stabilizes the joint during weight bearing.

Each stifle has two menisci. The medial is injured far more frequently because it is firmly attached to the tibia and cannot shift away from the abnormal tibial movement during CCL rupture.

SustainableVet.org confirms: the medial meniscus is more prone to injury because it is firmly attached to the tibia. When the tibia slides forward, it is compressed by the femoral condyle.

Why meniscal tears occur after TPLO

Latent tears missed at surgery

At the time of TPLO, the surgeon examines the meniscus through a small arthrotomy or arthroscopy and removes any clearly damaged tissue. However, not all tears are visible at surgery.

Small partial-thickness tears or areas of early degeneration may not be identifiable intraoperatively but progress to complete tears in the weeks or months after surgery.

PMC confirms: post-surgical meniscal pathology may be due to failure of diagnosis at the time of surgery (latent tears) or a result of residual joint instability (post-liminary tears).

Residual joint instability after TPLO

TPLO eliminates the cranial shear force that destabilized the joint. However, the stifle undergoes significant remodeling in the weeks after surgery, and some residual instability may persist during this period.

This can subject a structurally weakened meniscus to loading forces that produce tearing.

SustainableVet.org confirms: meniscal tears after TPLO can occur due to ongoing joint instability before surgery, direct trauma, or degenerative changes.

Progressive degeneration

Older dogs are at higher risk for meniscal tears because the meniscus undergoes age-related degeneration -- loss of collagen fiber organization, reduced cell density, and decreased water content.

PMC confirms: increasing age is a risk factor for medial meniscal tear; the meniscus experiences oxidative stress and abnormal matrix organization that can lead to injury under normal loading forces.

Concurrent vs. late meniscal tears

Concurrent (primary) tears

These are meniscal tears present at the time of TPLO and treated during the original surgery. PubMed data found a concurrent meniscal tear prevalence of 32.2% in dogs undergoing TPLO.

These are removed at the time of the procedure via arthrotomy or arthroscopy.

Late (secondary) tears

These are meniscal tears that develop after TPLO in a previously intact or adequately treated meniscus. The PubMed TPLO arthroscopy study found a late meniscal tear incidence of 5.6%.

RCVS Canine Cruciate Registry confirms late meniscal tears are seen in 2 to 22% of cases.

SustainableVet.org confirms: a secondary meniscus tear often happens weeks or months after the initial procedure and results in immediate pain, limping, and reluctance to move.

Symptoms of a post-TPLO meniscal tear

Sudden lameness regression: the most characteristic sign. A dog making steady progress suddenly becomes lame on the operated leg. This is distinct from the gradual variability of normal TPLO recovery.

Audible or palpable meniscal click: a clicking or popping sound during stifle flexion and extension. SustainableVet.org confirms the knee may produce a clicking sound when moving. The click is heard when the torn meniscal flap is displaced by the femoral condyle.

Pain on stifle manipulation: the dog flinches, vocalizes, or resists when the stifle is flexed through its range. This distinguishes pain from benign mechanical clicking.

Stifle swelling: joint effusion may increase from the baseline level. The joint feels fuller and may be warmer than the contralateral stifle.

Reluctance to bear weight: the dog shifts weight off the operated leg, holds the leg up, or toe-touches only.

SustainableVet.org confirms: symptoms include a sudden return of lameness, difficulty bearing weight, or a clicking or popping sound when the knee moves; dogs may yelp when standing or walking.

Diagnosis

Veterinary evaluation includes:

Physical examination: stifle manipulation to assess pain, range of motion, joint effusion, and presence of a palpable meniscal click. The McMurray-type maneuver and medial meniscal compression test are used to localize meniscal pain.

Radiographs: assess joint effusion (fat pad displacement), osteotomy healing, and implant position. Radiographs do not directly image the meniscus but rule out implant complications as the cause of lameness.

Arthroscopy or arthrotomy: definitive diagnosis. Direct visualization of the meniscus under anesthesia identifies the location, type, and severity of the tear.

Treatment

Conservative management

Small or partial-thickness tears without significant clinical signs can be managed conservatively with:

• NSAIDs for 4 to 8 weeks
• Strict activity restriction
• Joint supplements (omega-3 fatty acids, glucosamine, chondroitin)
• Reassessment if signs do not resolve

SustainableVet.org confirms: small tears may be managed with rest, NSAIDs, and joint supplements; but severe cases often require surgical intervention.

Partial meniscectomy

The definitive treatment for complete or symptomatic meniscal tears. The surgeon removes the damaged portion of the meniscus arthroscopically or via a small arthrotomy, leaving the undamaged portion intact.

The outcomes of partial meniscectomy are excellent. PubMed confirms: all dogs with late meniscal tears treated by partial meniscectomy returned to peak postoperative limb function based on client-assessed outcomes.

AVMA research confirms: treatment for meniscal tear results in significant improvement in lameness, with postoperative outcomes at 6 months comparable to dogs with intact menisci.

RCVS confirms: meniscal tears are treated by removing the torn portion. Dogs with long-term meniscal tears have a bit more osteoarthritis but generally maintain a good quality of life.

Post-meniscectomy recovery

Recovery after partial meniscectomy is typically faster than the original TPLO recovery. The osteotomy is already healed; the additional recovery is for the joint to settle after the meniscectomy.

Most dogs return to normal activity within 4 to 8 weeks.

Frequently asked questions

How do I know if it is a meniscal tear or normal recovery variability?

The key is trajectory. Normal recovery shows week-over-week improvement with occasional minor setbacks. A meniscal tear produces a clear regression: the dog was improving, then suddenly lame.

If your dog has been consistently improving and then becomes acutely lame, contact your vet the same day.

Can a meniscal tear be seen on X-ray?

No. Radiographs cannot image cartilage. X-rays assess bone, implant, and joint effusion. A suspected meniscal tear requires arthroscopy or an MRI (less common in veterinary practice) for definitive diagnosis.

Will my dog need another general anesthetic for the meniscectomy?

Yes. Arthroscopy or arthrotomy for partial meniscectomy requires general anesthesia. The procedure is typically shorter than the original TPLO and recovery is faster because the plate and osteotomy are already healed.

Is there anything that could have been done to prevent this?

Not reliably. The risk of late meniscal tears is partly structural (inherent joint instability during healing), partly degenerative (pre-existing meniscal weakness), and partly age-related.

Strict activity restriction during recovery reduces the risk by minimizing the abnormal joint loading that can damage a weakened meniscus, but it cannot eliminate risk entirely.

My dog had a concurrent meniscal tear treated at the time of TPLO. Is the outcome worse?

No.

AVMA research confirms similar midterm functional outcomes for TPLO plus meniscectomy vs TPLO alone in dogs with intact menisci.
