What to Expect After TPLO Surgery in Dogs
Learn what to expect after TPLO surgery, including pain, swelling, healing time, and care tips for your dog’s smooth recovery.
Understanding the TPLO Surgery Recovery Process
TPLO (Tibial Plateau Leveling Osteotomy) surgery is a corrective procedure used to stabilize a dog’s knee joint after a cruciate ligament tear.
It involves cutting and repositioning the top of the tibia, then securing it with a metal plate to restore stability and proper limb function. Recovery from TPLO is gradual and requires patience, structure, and veterinary guidance.
- Purpose of the Surgery: The goal is to eliminate joint instability and allow safe, pain-free movement once the bone heals.
- Duration of Recovery: Healing usually takes several weeks, not days, with restricted activity essential during the early phase.
- Owner Expectation: Progress is steady rather than immediate, with visible improvement appearing over time.
A disciplined recovery routine ensures lasting surgical success and long-term joint health.
The First 24–48 Hours After TPLO Surgery
The first two days after TPLO surgery are the most delicate phase of recovery. Your dog will be tired, slightly unsteady, and possibly anxious due to anesthesia and medication effects. Close supervision and a calm environment are essential during this period.
- Post-Anesthesia Drowsiness: Your dog may sleep most of the first day and have a slightly uncoordinated walk. This is normal as anesthesia wears off.
- Mild Swelling or Oozing: Small amounts of swelling near the incision are expected. Applying a cold compress can help reduce discomfort.
- Limited Appetite: Some dogs may eat less or refuse food temporarily. Offering small, bland meals often helps.
- Pain and Comfort Management: Administer medications exactly as prescribed and provide soft bedding in a confined area.
- Calm Environment: Keep noise, movement, and other pets to a minimum to reduce stress and prevent sudden movements.
Your dog’s comfort and stability during these first 48 hours lay the foundation for smooth healing and pain-free recovery.
Common Side Effects After TPLO Surgery
Mild side effects are a normal part of recovery after TPLO surgery. Recognizing what’s expected—and when to call your vet—helps prevent complications and keeps recovery on track.
- Mild Swelling and Bruising: Slight swelling around the incision and upper leg is common and typically peaks within three days.
- Temporary Limping: Your dog may refuse to put full weight on the operated leg for a week or two. Gradual improvement is expected.
- Drowsiness: Sedatives and pain medications can cause temporary sleepiness or slower reactions.
- Appetite and Bowel Changes: Some dogs may eat less or have mild constipation due to reduced movement or medication effects.
- When to Call Your Vet: Seek professional help if swelling worsens, bleeding occurs, or your dog cries excessively when moving.
These effects usually resolve within the first week, but early observation ensures proper healing and prevents serious issues.
Pain and Medication Management After TPLO Surgery
Pain control is one of the most critical parts of TPLO recovery. Properly managed pain keeps your dog calm, promotes healing, and prevents unnecessary movement.
- Pain Management Timeline: Most dogs need prescription pain relief for 7–10 days after surgery. Discomfort typically lessens gradually over this period.
- Vet-Prescribed Medications: Common options include NSAIDs for inflammation, opioids for pain, and antibiotics to prevent infection.
- Dosage Consistency: Always follow dosage instructions carefully—skipping doses or doubling medication can be dangerous.
- Observation for Side Effects: Watch for vomiting, diarrhea, loss of appetite, or restlessness, which may indicate an adverse drug reaction.
- Comfort Measures: Keep your dog in a warm, soft area and use supportive bedding to ease joint pressure.
Adhering to your vet’s medication plan ensures your dog stays comfortable and avoids unnecessary pain or surgical complications.
Post-Surgery Swelling and Incision Care After TPLO
Incision care is vital for infection prevention and smooth healing after TPLO surgery. Some swelling is normal, but cleanliness and protection are key to avoiding complications.
- Normal Swelling: Mild swelling or bruising around the incision is expected for 3–5 days, peaking early and then gradually fading.
- Keep the Site Clean and Dry: Avoid bathing your dog or letting the incision get wet. Gently wipe away any dried fluid if advised by your vet.
- Prevent Licking or Chewing: Use an e-collar or inflatable collar to stop your dog from disturbing the incision.
- No Ointments Unless Approved: Applying creams or disinfectants can interfere with healing unless specifically recommended by your vet.
- Watch for Warning Signs: Redness spreading outward, yellow drainage, or foul odor could signal infection and require immediate attention.
Proper incision care speeds healing and keeps your dog comfortable while reducing the risk of post-surgical infection.
Rest and Restricted Activity: The First 6–8 Weeks After TPLO Surgery
Strict rest during the first six to eight weeks after TPLO surgery is essential for bone and joint healing. Controlled confinement prevents accidental strain or plate movement.
- Crate or Pen Rest: Keep your dog confined in a small, secure area to stop jumping or running. Movement should only occur under supervision.
- Assisting Movement: Support your dog with a sling or harness when standing or walking short distances to reduce leg pressure.
- Short Leash Walks: Potty breaks should last no longer than five minutes, using a short leash to prevent pulling or sudden moves.
- Avoid Stairs and Furniture: Use ramps or baby gates to prevent climbing or slipping on slick floors.
- Monitor Behavior: Even small bursts of excitement can strain healing tissue, so maintain calm surroundings at all times.
Consistent rest during this early recovery phase ensures proper bone fusion, strong joint stability, and a faster transition to physical therapy.
Physical Therapy and Rehabilitation Timeline After TPLO Surgery
Physical therapy is one of the most important steps in TPLO recovery. It helps restore flexibility, rebuild strength, and ensure your dog’s leg returns to full function safely. Starting exercises too early can cause setbacks, so timing and supervision are key.
- Initial Stage (Weeks 1–2): Focus solely on rest and incision healing. Gentle massage or cold compresses may be introduced if approved by your vet.
- Early Therapy (Weeks 2–6): Begin passive range-of-motion (PROM) exercises under supervision to maintain flexibility. Short, slow leash walks are added gradually.
- Intermediate Therapy (Weeks 6–10): Controlled weight-bearing and underwater treadmill sessions help strengthen muscles without stressing the joint.
- Advanced Therapy (Weeks 10–12): Strength and coordination exercises like sit-to-stand drills or balance pads improve stability and limb confidence.
- Full Conditioning (After 12 Weeks): Return to normal walking, moderate play, and outdoor activities once cleared by X-rays and your vet.
Structured physical therapy significantly improves recovery time, reduces stiffness, and builds long-term joint strength for a smoother return to normal life.
Follow-Up Vet Visits and X-Rays After TPLO Surgery
Regular veterinary checkups are essential to monitor healing and prevent complications after TPLO surgery. These visits allow your vet to assess bone recovery, adjust medications, and ensure activity levels match your dog’s progress.
- 2-Week Visit: The first check confirms incision healing and removes stitches if necessary. Your vet may also review pain management and early mobility status.
- 6-Week Visit: Follow-up X-rays evaluate bone alignment and early plate stability. If healing looks good, limited physical therapy or short walks may begin.
- 12-Week Visit: This is a key milestone. Final X-rays confirm bone fusion and plate integrity. Your vet may lift most activity restrictions at this stage.
- Adjusting Recovery Plans: Based on X-ray findings, your vet might extend rest or modify therapy intensity to avoid reinjury.
- Additional Appointments: Some cases—especially older or large-breed dogs—require longer observation and occasional rechecks.
Attending all follow-ups ensures bone stability is verified before your dog resumes full activity, preventing premature stress on the repaired leg.
Long-Term Healing: 3–6 Months After TPLO Surgery
The long-term healing phase focuses on restoring strength, balance, and endurance. While most dogs recover well within 12 weeks, complete bone remodeling and joint adaptation can continue for several months.
- Gradual Return to Walks: Controlled walking can increase in distance and frequency around the three-month mark.
- Reintroduction to Play: Gentle play and light off-leash activity can resume around four to five months, but jumping or running should still be limited.
- Monitoring for Stiffness: Occasional stiffness after rest is normal, but consistent limping or pain may signal joint irritation.
- Weight and Fitness Management: Maintaining an ideal weight reduces stress on the operated knee and helps prevent future injuries.
- Ongoing Strength Work: Continued low-impact exercises like swimming or incline walking maintain muscle tone and mobility.
By six months, most dogs achieve full function and stability. Staying patient during this phase ensures a lifetime of stronger, pain-free movement.
Signs of Complications After TPLO Surgery
While TPLO surgery has a high success rate, complications can occur if healing doesn’t go as planned. Early recognition of these signs helps prevent long-term issues or surgical failure.
- Excessive Swelling or Redness: Persistent or spreading swelling near the incision may indicate infection or inflammation.
- Persistent Lameness: If your dog continues to limp beyond the expected recovery window, consult your vet for evaluation.
- Discharge or Odor: Yellow or bloody drainage from the incision is not normal and needs immediate attention.
- Sudden Pain or Crying: Sharp pain, whining, or refusal to walk could mean plate loosening, infection, or muscle strain.
- Reluctance to Bear Weight: Dogs that suddenly refuse to use the leg may have experienced implant shifting or bone stress.
- Fever or Lethargy: Systemic signs like fever and fatigue can accompany infection or inflammation.
Quick veterinary intervention can resolve most issues before they become serious, ensuring the surgical repair remains stable and successful.
Conclusion
TPLO recovery is a gradual, structured process that rewards patience and consistency. While the first few weeks focus on pain control and rest, the following months emphasize rehabilitation and rebuilding strength.
- Recovery Stages: Healing progresses through rest, gentle movement, and physical therapy over 8–12 weeks.
- Owner Involvement: Close observation, timely medication, and maintaining a calm environment play a vital role in recovery quality.
- Veterinary Guidance: Regular follow-up visits and X-rays help track healing and prevent complications.
- Long-Term Outcome: With steady, supervised care, most dogs return to full mobility, enjoying pain-free movement and lasting joint stability.

FAQs
How long before my dog walks normally after TPLO?
Most dogs begin bearing weight on the operated leg within 2–3 weeks after surgery. However, a normal walking gait typically returns around 8–12 weeks, depending on size, age, and muscle recovery. Consistent physical therapy helps your dog regain strength and stability faster.
When will swelling and bruising go away?
Mild swelling and bruising near the incision site are normal for the first 5–7 days. Applying cold compresses for short intervals during the first few days can reduce inflammation. If swelling worsens or lasts beyond two weeks, contact your veterinarian for an evaluation.
Can my dog climb stairs during recovery?
Stairs should be strictly avoided during the first 6–8 weeks. Climbing too early can strain the healing tibia and affect plate stability. Once cleared by your vet, short, slow stair use with leash support may begin as part of the advanced recovery phase.
How long until the bone fully heals?
The bone typically takes 10–12 weeks to fuse completely, though full remodeling and strength return can continue up to 6 months. Follow-up X-rays confirm when it’s safe to resume unrestricted activity.
When can I stop using the cone?
The cone or e-collar should remain on until the incision has fully healed—usually about 10–14 days. Removing it too soon risks licking or chewing, which can cause infection or wound reopening. Always follow your vet’s approval before stopping use.

How to Keep a Dog Calm After TPLO Surgery
Learn how to keep your dog calm after TPLO surgery using rest, crate training, and soothing techniques for safe, stress-free recovery.
Why Keeping Your Dog Calm After TPLO Surgery Is So Important
After TPLO surgery, keeping your dog calm is one of the most critical parts of recovery. The bone, plate, and screws need several weeks to heal securely, and any sudden movement or overactivity can disrupt that process. Rest allows tissues to rebuild and the surgical site to stabilize without extra strain.
- Prevents Implant Failure: The metal plate and screws hold the bone in position during healing. Jumping or running too early can loosen or shift these implants, leading to painful setbacks or revision surgery.
- Reduces Swelling and Inflammation: Controlled rest limits joint stress and prevents excess fluid buildup that delays bone fusion.
- Supports Safe Bone Healing: The tibia needs time for callus formation and proper alignment. Calm, limited movement ensures consistent recovery.
- Avoids Reinjury: Dogs often feel better before the bone fully heals, making them eager to move. Restricting activity keeps them from damaging soft tissue or undoing surgical repairs.
- Promotes Mental Stability: A calm environment lowers stress hormones, which supports both physical and emotional healing.
Maintaining your dog’s calm behavior after TPLO surgery is not just about obedience — it’s about protecting the repair and ensuring a smooth, complication-free recovery.
How Long Dogs Need to Stay Calm After TPLO Surgery
The healing process after TPLO surgery requires strict control of movement. Dogs typically need 6–8 weeks of restricted activity before returning to light exercise, though this can vary depending on size, age, and overall health. Remaining calm during this period ensures the bone plate stabilizes and heals properly.
- Initial Rest Period (Weeks 0–6): Dogs should stay confined to a crate or pen with only brief, supervised leash walks for bathroom breaks.
- Gradual Activity Increase (Weeks 6–10): Once X-rays confirm bone healing, your vet may approve gentle walking or light physical therapy.
- Long-Term Transition (After 10 Weeks): Controlled movement replaces full restriction. Activities like swimming or slow leash walks promote strength safely.
- Recovery Variations: Large or older dogs may need longer rest, while smaller breeds often heal faster due to lower joint stress.
- Vet-Guided Plan: Always follow your veterinarian’s recovery schedule and delay activity until your dog’s gait and confidence improve.
Patience during the calm phase prevents reinjury and ensures the surgical repair remains stable throughout the healing process.
Preparing a Safe Recovery Space Before Bringing Your Dog Home
Setting up a calm, controlled environment before your dog returns home is key to a smooth recovery. A secure space prevents accidental slips, jumping, or overexcitement while your dog adjusts to limited movement.
- Choose a Confined Area: Use a crate, playpen, or small gated room to limit running or climbing. Ensure there’s enough room to lie down comfortably.
- Provide Non-Slip Flooring: Mats or rugs prevent your dog from slipping on tiles or hardwood, reducing strain on the surgical leg.
- Use Soft Bedding: Thick, supportive bedding cushions the joint and prevents pressure sores during long rest periods.
- Keep Essentials Close: Place food, water, and toys within easy reach so your dog doesn’t need to move around unnecessarily.
- Minimize Noise and Distractions: Keep the space quiet and away from household traffic to maintain calm behavior.
A well-prepared environment helps your dog feel secure and relaxed, supporting both emotional and physical healing after surgery.
Crate Rest and Confinement Tips After TPLO Surgery
Crate rest is one of the safest ways to control your dog’s activity after TPLO surgery. When used correctly, it supports proper bone healing while reducing stress and the temptation to move too much.
- Purpose of Crate Rest: It restricts movement, preventing your dog from jumping, twisting, or running, which could damage the surgical site.
- Make the Crate Comfortable: Add soft bedding, a familiar blanket, and safe chew toys to make the space relaxing.
- Reduce Stress: Use calming scents or gentle music near the crate to create a peaceful environment.
- Positive Association: Feed meals or offer treats inside the crate so your dog views it as a safe, comforting space.
- Gradual Out-of-Crate Time: Once cleared by your vet, increase supervised movement slowly—starting with short walks or passive exercises.
Proper crate management helps your dog stay calm, safe, and comfortable throughout recovery without feeling isolated.
Using Calming Techniques and Tools After TPLO Surgery
Keeping your dog emotionally calm is as important as restricting physical activity. Calming tools and consistent routines help reduce anxiety during recovery.
- Soothing Sounds: Soft music or white noise masks outside distractions and helps anxious dogs relax.
- Natural Calming Aids: Pheromone diffusers, herbal sprays, or vet-approved supplements can reduce restlessness naturally.
- Predictable Routine: Regular feeding, potty breaks, and gentle interactions give structure and reassurance.
- Gentle Reassurance: Stay near your dog, speak calmly, and avoid sudden handling that could trigger anxiety or pain.
- Avoid Overstimulation: Limit visitors, children, or other pets from crowding your dog during recovery.
Combining environmental control with emotional support keeps your dog relaxed, promoting steady healing and preventing stress-related complications.
Managing Pain and Discomfort to Keep Dogs Calm
Unmanaged pain can make even the calmest dog restless after TPLO surgery. Pain relief not only promotes comfort but also prevents agitation and unwanted movement that could slow recovery.
- Follow Medication Instructions: Administer pain relievers and anti-inflammatories exactly as prescribed by your veterinarian.
- Watch for Signs of Pain: Whining, panting, or licking the surgical site may signal discomfort or medication wearing off.
- Monitor Activity Levels: A calm, comfortable dog rests easily; pacing or agitation may mean dosage adjustment is needed.
- Communicate with Your Vet: If pain persists despite medication, contact your vet before changing any drug schedule.
- Comfort Measures: Provide soft bedding, maintain room temperature, and ensure your dog rests undisturbed.
Consistent pain control encourages relaxation and speeds up healing by keeping stress levels low and mobility safe.
Mental Stimulation Without Physical Strain After TPLO Surgery
A calm mind leads to a calmer body. Mental enrichment keeps your dog engaged during rest without risking physical strain on the operated leg.
- Puzzle Feeders: Interactive feeding toys make mealtime mentally stimulating and extend eating time for restless dogs.
- Low-Impact Toys: Offer safe chew toys that keep your dog occupied without encouraging jumping or chasing.
- Gentle Obedience Training: Teach stationary cues like “stay,” “touch,” or “watch me” using treats and calm praise.
- Scent Games: Hide treats within reach to engage your dog’s nose and brain while keeping activity minimal.
- Supervised Interaction: Spend time nearby to provide emotional comfort and prevent boredom-related anxiety.
Mental stimulation helps reduce frustration during confinement and keeps your dog emotionally balanced throughout recovery.
Walking and Potty Breaks During the Recovery Period
Bathroom breaks must be short, calm, and strictly supervised during TPLO recovery. Controlled leash walks prevent slips, overexcitement, or sudden pulling that could harm the healing leg.
- Use a Short Leash and Harness: A well-fitted harness offers better control without straining the neck or back.
- Keep Walks Brief: Limit outings to 3–5 minutes, just long enough for your dog to relieve itself.
- Stable Ground: Choose grass or rubber mats over slippery concrete or tile surfaces.
- Avoid Stimulation: Steer clear of other dogs, loud noises, or distractions that might trigger sudden movement.
- Assist with Support: Some dogs benefit from a rear-end support sling during early recovery to maintain balance.
Calm, structured potty breaks maintain consistency while protecting the joint from unnecessary stress.
When to Seek Help for Restlessness After TPLO Surgery
Even with care, some dogs may struggle to stay calm during recovery. Persistent anxiety, restlessness, or agitation can interfere with healing and should not be ignored.
- Signs of Anxiety: Constant whining, pacing, or trying to escape confinement may indicate emotional distress.
- Excessive Movement: If your dog repeatedly gets up, circles, or limps after short walks, contact your vet for evaluation.
- Pain-Related Restlessness: Discomfort often shows as panting, licking the leg, or refusing to settle. Pain management adjustments may be necessary.
- Sedation Support: Vets can prescribe mild sedatives or calming medications for dogs who remain overly anxious.
- Separation Anxiety: If your dog becomes distressed when left alone, consider gradual desensitization or temporary companionship support.
Prompt veterinary guidance ensures your dog stays comfortable, safe, and mentally at ease throughout recovery.
Conclusion
Keeping your dog calm after TPLO surgery is just as important as the surgery itself. Controlled rest allows the bone, joint, and surrounding tissues to heal without stress or strain.
- Patience and Structure: A calm, predictable routine reduces anxiety and prevents sudden movements that can harm recovery.
- Balanced Care: Combine physical confinement with emotional comfort—soft bedding, quiet space, and gentle reassurance.
- Veterinary Support: Regular check-ins ensure pain and stress are properly managed throughout the healing period.
By creating a structured, peaceful recovery environment, you’ll help your dog heal faster, stay comfortable, and return to normal activity safely and confidently.

Caring for the Incision Site
In the first two weeks after FHO surgery, taking care of the incision is crucial for preventing infection and promoting healing.
- How often to check the wound: Inspect the incision 1–2 times daily for redness, swelling, or discharge.
- Signs of infection to watch for: Look out for pus, foul smell, increased redness, or warmth around the incision. If your dog licks the area excessively or seems in pain, contact your vet.
- Keeping the incision clean and dry: Do not apply creams or sprays unless your vet advises. Avoid letting the incision get wet or dirty—this includes keeping your dog away from muddy areas or damp grass.
- Bathing restrictions and suture removal timing: Do not bathe your dog until the sutures are removed or the incision is fully healed—typically 10–14 days after surgery. Your vet will advise if staples or stitches need removal.
Keep your dog’s environment clean and calm. Prevent licking with an E-collar or soft recovery cone. With good wound care, you reduce the chance of infection and help your dog heal faster.
Early Rehab Tips (Days 4–14)
This phase introduces gentle movement to prevent stiffness and starts building comfort with basic activity.
- Warm compresses and massage: Apply a warm compress (not hot) for 10 minutes before massage. Gently massage muscles around the hip to improve blood flow and reduce tension.
- Gradual leash walking routine: Begin with 5-minute walks on flat surfaces 2–3 times a day. Use a short leash and walk slowly.
- Supporting with sling/harness indoors: For dogs with weak hind limbs, a rear-support sling or towel under the hips helps reduce strain.
- Encouraging calm behavior while healing: Limit excitement and prevent jumping or rough play. Use food puzzles and chews to keep your dog mentally stimulated while physically resting.
These small steps set the foundation for long-term healing. Always follow your vet’s rehab plan and observe how your dog responds to gentle movement.
Strength-Building and Exercise (Weeks 2–6)
As healing progresses, the focus shifts to rebuilding strength and range of motion in the hip and leg.
- Sit-to-stand drills and wall sits: Encourage your dog to sit and stand slowly, 5–10 times in a row. Use a wall to support the healthy side during “wall sits.”
- Walking up inclines and gentle ramps: Start with low slopes or shallow ramps to engage the hip joint without stress.
- Controlled leash walks: how to progress safely: Increase walk time by 5 minutes each week if no limping occurs. Avoid slippery or uneven surfaces.
- Hydrotherapy and swimming introduction: Swimming is a low-impact way to rebuild muscles. Use a life vest and only in vet-approved, clean water environments.
- Using ice after exercise: Apply ice for 10–15 minutes on the hip after exercise sessions to reduce inflammation.
This stage helps restore normal movement. Track progress daily and adjust activities if soreness or fatigue appears.
Monitoring Healing and When to Call the Vet
Ongoing monitoring helps catch issues early and ensures your dog stays on track with recovery.
- Follow-up exam timing: Most vets schedule a recheck around 2 weeks post-surgery, then again at 6–8 weeks.
- What is normal vs. warning signs: Mild swelling, slight limping, or low activity is common. Warning signs include severe limping, refusal to walk, or signs of pain when touched.
- Dealing with swelling, bruising, or seroma: Minor swelling or fluid buildup (seroma) is usually not serious. If the area gets warm or painful, call your vet.
- When rehab support is needed: If your dog struggles with exercises or limping worsens, seek help from a vet or certified canine rehab therapist.
Don’t ignore small changes—early action prevents long-term issues. Regular updates with your vet ensure recovery stays on track.

FAQs
How long should I restrict my dog after FHO surgery?
Activity should be restricted for at least 6–8 weeks after FHO surgery. Crate rest and controlled leash walks are important during the early healing phase. Your vet will guide you on when to slowly increase activity. Full recovery can take up to 12 weeks, depending on your dog’s progress and comfort level.
What are the best rehab exercises after FHO?
Start with gentle leash walking and passive range-of-motion stretches. As healing progresses, add sit-to-stand drills, incline walking, and later hydrotherapy. Each exercise should be done slowly and carefully. Always follow your vet’s or rehab therapist’s guidance to prevent overuse and promote proper muscle rebuilding.
Can my dog go upstairs during recovery?
No, stairs should be avoided during the first few weeks. They can strain healing muscles and joints. If stairs are unavoidable, use a sling or harness to support your dog. Once your vet approves, short stair use with supervision may be allowed around weeks 4–6 of recovery.
When is hydrotherapy safe to start?
Hydrotherapy can usually begin around week 2 or 3, once the incision is fully healed. It’s a low-impact way to build strength and improve movement. Always get your vet’s approval before starting, and ensure sessions are guided by trained professionals for best results.
What if my dog still limps weeks after surgery?
Some limping is normal in the early stages, especially if your dog hasn’t regained full muscle strength. But if limping continues beyond 6–8 weeks or worsens, consult your vet. It may signal delayed healing, discomfort, or the need for adjusted rehabilitation exercises.
Is it normal for the incision to look bruised?
Yes, mild bruising or slight swelling around the incision is common during the first few days. It should gradually improve. However, if the area becomes red, warm, painful, or oozes pus, contact your vet immediately as these may be signs of infection.

Is Surgery Necessary for Medial Patellar Luxation in Dogs?
Learn when surgery is necessary for medial patellar luxation in dogs, what to expect, and when non-surgical treatment may be enough
What Is Medial Patellar Luxation (MPL)?
Medial Patellar Luxation (MPL) is a condition where a dog’s kneecap (patella) slips out of its normal groove and moves toward the inside of the leg. This misalignment causes the knee joint to become unstable and painful.
- Knee and mobility impact: When the patella moves out of place, it interferes with the smooth motion of the leg. This makes walking, running, and standing more difficult. Over time, the joint may develop inflammation, arthritis, or muscle loss if left untreated.
- Signs and symptoms: Most owners notice limping, skipping steps, or the dog holding one leg up. Some dogs may show a hopping gait or reluctance to run, climb stairs, or jump. The signs may come and go in mild cases or become more constant as the condition worsens.
Recognizing these symptoms early helps ensure your dog receives proper care before long-term damage sets in. A veterinary exam is needed to confirm MPL and determine its severity.
Understanding MPL Grades and Why They Matter
Veterinarians classify Medial Patellar Luxation (MPL) into four grades based on how easily the kneecap moves out of place and how often it stays there. These grades help guide treatment decisions and predict outcomes.
- Grade I: The kneecap can be manually moved out of place but returns on its own. Dogs may not show clear symptoms and often walk normally.
- Grade II: The patella dislocates on its own but can return manually or with movement. Dogs may show occasional limping or skipping.
- Grade III: The kneecap is out most of the time but can be pushed back into place. Dogs often have lameness or abnormal gait.
- Grade IV: The kneecap is permanently out of place and cannot be returned. Dogs have trouble walking and may show pain or severe limb deformity.
Grades I and some Grade II cases may be managed without surgery. Grades III and IV almost always require surgical correction to prevent long-term joint damage and restore function.
Read more:
Can Mild Cases Be Managed Without Surgery?
Yes, surgery is not always necessary for every case of Medial Patellar Luxation. Mild cases—especially Grade I and some Grade II—can often be managed successfully with conservative treatment, especially when symptoms are minimal.
- Good candidates for non-surgical care: Small breed dogs under 20–25 pounds, dogs with occasional limping but no consistent pain, or older pets with lower activity levels.
- When surgery may not be needed: If your dog moves normally most of the time, does not show signs of chronic pain, and maintains good muscle strength in the leg.
- Monitoring is key: Dogs with mild MPL should be checked regularly to make sure the condition isn’t getting worse.
Managing mild MPL early can delay or even avoid the need for surgery. However, owners must stay alert for signs of progression, such as frequent limping or reduced activity. Your veterinarian can help determine if surgery is needed later based on your dog’s symptoms and lifestyle.
Non-Surgical Management Options
For dogs with mild MPL or those not ready for surgery, there are several non-surgical options that help reduce pain and support joint function.
- Weight control: Keeping your dog at a healthy weight reduces stress on the knees and slows joint wear.
- Exercise restrictions: Avoid jumping, fast running, or slippery surfaces. Controlled walks and low-impact movement are safer.
- Joint supplements: Products containing glucosamine, chondroitin, or omega-3 fatty acids support cartilage health and reduce inflammation.
- Anti-inflammatory medications: Vets may prescribe NSAIDs to relieve pain and improve movement in flare-up periods.
- Physical therapy: Gentle stretching, strength-building exercises, or laser therapy help maintain muscle tone and balance.
- Hydrotherapy: Swimming or underwater treadmill therapy allows your dog to exercise without putting weight on the joint.
These approaches do not cure MPL, but they often keep symptoms under control, especially in mild or early-stage cases. Regular follow-ups are important to monitor changes in mobility or comfort.

When Surgery Becomes Necessary
Surgery becomes necessary when non-surgical treatments no longer manage symptoms or when the patellar luxation is more severe (Grades III–IV). Early surgery can prevent joint damage, chronic pain, and loss of mobility.
- Signs conservative care isn’t working: Frequent limping, pain during movement, decreased activity, or worsening gait even with rest and medications.
- When surgery is recommended right away: Grade III or IV MPL, kneecap always dislocated, clear signs of pain, or limb deformity. Puppies with severe signs may need early correction to avoid growth issues.
- Risks of delaying surgery: Untreated MPL can lead to arthritis, muscle loss, and worsening joint misalignment. Long-term damage may make surgery and recovery more difficult later.
If your dog struggles to walk or play comfortably, it’s time to discuss surgery. Procedures are generally safe and have a high success rate, especially when done early. Your vet will guide you through the options based on your dog’s condition, age, and lifestyle.
What Happens If MPL Is Left Untreated?
Leaving Medial Patellar Luxation (MPL) untreated can lead to long-term problems in the knee joint. Even if symptoms seem mild at first, the condition often worsens over time.
- Joint degeneration and arthritis: Repeated luxation wears down cartilage, leading to joint inflammation and permanent damage.
- Pain and worsening lameness: As the kneecap slips more often, your dog may limp more, avoid activity, or show signs of constant discomfort.
- Cranial cruciate ligament (CCL) tears: Long-term instability puts added strain on other structures, especially the CCL, increasing the risk of rupture and more serious surgery.
Delaying treatment can turn a manageable condition into a much more complex problem. While mild cases can be monitored, dogs with moderate or severe MPL often benefit from early surgical correction to avoid joint breakdown and pain. Regular vet check-ups help track changes and guide timely intervention.

Surgical Treatment Options for MPL
Several surgical options are available to correct Medial Patellar Luxation, depending on the grade of the condition and your dog’s unique anatomy.
- Trochlear sulcoplasty: The surgeon deepens the groove where the kneecap sits, helping it stay in place during movement.
- Tibial tuberosity transposition (TTT): This procedure moves the bony attachment of the patellar tendon to better align the kneecap with the groove.
- Soft tissue techniques: Tight or loose tissues around the knee are either released or tightened to improve stability.
- Bone corrections (osteotomy): In severe cases with limb deformities, cutting and realigning bones is needed to restore proper function.
These procedures are often combined during surgery to give the best results. The goal is to keep the kneecap stable, reduce pain, and prevent further joint damage. Your vet or surgeon will select the right combination based on X-rays, gait analysis, and physical exam findings.
Recovery and Long-Term Outlook After Surgery
Recovery after MPL surgery involves several weeks of rest, careful monitoring, and gradual return to activity. Most dogs do very well when owners follow post-operative care closely.
- Initial recovery: The first 2 weeks require crate rest and strict activity restriction. Pain medications and anti-inflammatories are typically prescribed.
- Gradual rehab: Controlled leash walks and home exercises start in weeks 3–6. Jumping, running, and stairs are limited until the vet gives clearance.
- Physical therapy: Many dogs benefit from structured rehab, including underwater treadmill, stretching, and muscle-strengthening to rebuild leg function.
Most dogs return to normal or near-normal activity within 8–12 weeks. Long-term outcomes are excellent for most cases, especially if the surgery is done before severe joint damage sets in. With successful surgery and proper care, your dog can enjoy a pain-free, active life again.
Does Breed or Size Affect Surgical Decisions?
Yes, breed and size play a major role in how veterinarians approach MPL treatment. While MPL is most common in small breeds, it can affect larger dogs too.
- Smaller breeds: Dogs like Pomeranians, Chihuahuas, and Yorkies commonly develop MPL and often respond very well to surgical correction.
- Large breeds: Surgery can be more complex due to body weight and bone structure. Outcomes are still good but may require more rehab and monitoring.
- Age and activity level: Younger dogs recover faster and may benefit more from early surgery. Active dogs are often treated sooner to prevent injury to other joints.
Your vet will consider breed, weight, limb alignment, and lifestyle when recommending surgery. Even large dogs can do well with the right surgical plan and consistent follow-up care.
Is Surgery Worth It? Cost vs Outcome
For many dogs, MPL surgery is a long-term investment in comfort and mobility. While the upfront cost can be significant, the benefits are often life-changing.
- Typical cost: MPL surgery ranges from $1,500 to $4,000 per knee depending on location, surgeon experience, and complexity.
- Early intervention saves money: Addressing MPL before it worsens reduces the chance of arthritis or ligament injuries, which require more costly treatment.
- Satisfaction and results: Most owners report high satisfaction. Dogs often return to walking, running, and playing with no pain and minimal limp.
While not every case requires surgery, it’s highly effective in moderate to severe cases or when quality of life is reduced. Discussing options with your vet can help you make a confident decision based on your dog’s needs and your budget.

FAQs
How do I know if my dog needs surgery for MPL?
Your vet will assess the severity (Grade I–IV), signs like limping, pain, or kneecap dislocation, and how much it affects your dog’s daily life. Surgery is usually needed for Grade III or IV, or if conservative care fails. A full exam, gait observation, and X-rays help decide if surgery is necessary.
Is surgery the only option for a Grade II luxating patella?
Not always. Some Grade II cases can be managed with rest, weight control, joint supplements, and physical therapy. But if your dog shows worsening pain or lameness, or the condition doesn't improve, surgery may still be recommended. Your vet will guide the best option based on how your dog responds.
Can a dog live a normal life without MPL surgery?
Mild cases (like Grade I) often don’t need surgery and dogs can live comfortably with conservative care. But moderate or severe cases may get worse without surgery, leading to pain, arthritis, or ligament injuries. A dog’s quality of life depends on how well symptoms are managed over time.
How successful is MPL surgery in dogs?
MPL surgery has a high success rate, especially when done early. Most dogs recover well, with reduced pain and improved mobility. Success depends on the dog’s size, the grade of luxation, and how well post-surgical rehab is followed. Reluxation or complications are rare but possible if care is inconsistent.
How much does MPL surgery cost on average?
The cost of MPL surgery typically ranges from $1,500 to $4,000 per knee, depending on your location, surgeon, and whether one or both knees are affected. Additional costs may include diagnostics, follow-up visits, and physical therapy. Some clinics offer financing or package plans to help manage expenses.
Is MPL surgery more risky in large breed dogs?
Surgery in large breeds may involve more challenges due to body weight and joint structure. While the risk of complications is slightly higher, outcomes are still good with proper surgical technique and rehab. Large dogs may need longer recovery and physical therapy, but many return to normal activity.

Medial Patellar Luxation Grades Explained
Clear guide to medial patellar luxation grades (I–IV) in dogs. Learn what each grade means, symptoms to watch for, and treatment options based on severity
What Is Medial Patellar Luxation (MPL)?
Medial Patellar Luxation (MPL) is a condition where a dog’s kneecap (patella) slips out of its normal position inside the femoral groove and moves toward the inside of the leg. This causes pain, limping, or skipping while walking. Over time, it can lead to joint damage or arthritis if not treated.
Commonly Affected Breeds
MPL is more common in small and toy breeds, though large breeds can also be affected.
- Pomeranians
- Yorkshire Terriers
- Chihuahuas
- Miniature and Toy Poodles
- Boston Terriers
- Pekingese
- Shih Tzus
- Some large breeds like Labrador Retrievers and Akitas
In many cases, the condition is inherited and may appear in both legs.
Why Grading Matters for Treatment
MPL is classified into four grades based on how easily the kneecap moves out of place. Grading helps the veterinarian decide the best treatment plan.
- Lower grades may not need surgery and can be managed with lifestyle changes.
- Higher grades often require surgery to correct the joint and improve function.
Understanding the grade is key to choosing the right care and predicting recovery success.

Understanding the MPL Grading System
Grade I Medial Patellar Luxation
In Grade I MPL, the patella can be moved out of place during a physical exam but returns to its normal position on its own. Most dogs do not show obvious signs of pain or discomfort.
Typical signs:
- Intermittent “skipping” gait on one back leg
- Kneecap slips briefly, then goes back into place
- No swelling or pain when resting
- Dogs remain active and playful
Is surgery needed?
- Usually not required.
- Vets often recommend monitoring, weight control, and joint supplements.
- Surgery may be considered if the condition worsens over time.
Most dogs with Grade I live comfortably without surgery, especially if they stay active, lean, and avoid rough play. Early diagnosis helps prevent progression to higher grades.
Grade II Medial Patellar Luxation
In Grade II, the kneecap slips out more often and may stay out until it is manually repositioned. Dogs may limp or have periods of discomfort after exercise.
Common symptoms:
- More frequent skipping or limping
- Patella may remain out for several steps
- Discomfort when running or turning quickly
- Muscle loss may begin over time if not treated
When is surgery considered?
- Surgery is recommended if symptoms worsen or become regular.
- Dogs that limp often or avoid using the leg benefit from correction.
- Joint damage may occur over time if left untreated.
Some dogs with Grade II improve with conservative care, but many eventually need surgery to avoid arthritis and improve leg use.
Grade III Medial Patellar Luxation
With Grade III MPL, the kneecap is out of place most of the time but can be pushed back into the groove during an exam. Dogs often have an abnormal gait and show clear signs of discomfort.
Functional impact:
- Frequent limping or stiffness, especially after activity
- “Bunny hopping” gait or dragging one leg
- Muscle wasting on the affected leg
- Joint swelling or changes in alignment
Surgical recommendation:
- Surgery is strongly recommended to restore leg function.
- If left untreated, arthritis and permanent joint damage may occur.
- Recovery may take longer, but outcomes are usually very good.
Grade III dogs often need both soft tissue and bone procedures. Timely surgery greatly improves their quality of life and movement.
Grade IV Medial Patellar Luxation
Grade IV is the most severe form. The patella is always out of place and cannot be manually moved back into position. The leg often appears twisted or underdeveloped due to poor use.
Severe signs:
- Constant lameness or inability to use the leg
- Abnormal bone shape and knee structure
- Significant pain, joint swelling, or deformity
- Difficulty standing, sitting, or walking normally
Need for advanced correction:
- Advanced surgery is required, often involving bone realignment.
- In some cases, staged procedures are needed to fully correct the limb.
- Recovery is longer and more closely monitored.
Even though Grade IV is complex, many dogs improve with surgery. While some may still have a limp, pain is usually reduced and mobility increases. Early treatment offers the best chance for comfort and stability.

How Vets Diagnose the Grade of MPL
Veterinarians use a mix of hands-on exams and imaging to diagnose the grade of Medial Patellar Luxation (MPL). The goal is to check how easily the kneecap moves out of place and how stable the joint is during movement.
Key Diagnostic Methods
- Physical exam: The vet checks for signs of discomfort, joint looseness, and muscle loss in the hind legs.
- Manual luxation test: While the dog is relaxed, the vet gently moves the patella to see if it slides out of place, how easily it moves, and whether it returns to the groove.
- Radiographs (X-rays): Used to check bone shape, joint alignment, and other knee problems like arthritis or bone rotation.
- Limb alignment studies: In advanced cases, special X-rays help measure bone angles and rotation, especially for surgical planning in Grade III or IV.
Accurate grading is key to choosing the right treatment. Early diagnosis allows for better planning and can prevent the condition from getting worse over time.
Read more:
Signs and Symptoms That Help Determine the Grade
MPL affects dogs differently depending on the grade. Symptoms often start mild but can worsen if the kneecap slips more often or stays out.
Common Symptoms by Grade
- Grade I: Mild, with occasional skipping or brief lameness. The dog usually walks normally between episodes.
- Grade II: More frequent skipping or limping. Some dogs start avoiding exercise or show leg stiffness after activity.
- Grade III: Constant limping or altered gait. Dogs may hop with both legs or show signs of pain during touch or movement.
- Grade IV: Severe dysfunction. Dogs often drag one leg or walk with bent knees. The limb may look twisted or underdeveloped.
Other Key Signs
- Skipping or bunny-hopping gait: Common in Grades II–III
- Bilateral signs: Both knees are often affected in small breeds
- Unilateral signs: Seen more often when injury causes MPL on one side
Observing the dog’s movement helps the vet match symptoms with the correct MPL grade and decide on treatment.
Treatment Options by Grade
Treatment for MPL depends on the grade, the dog’s age, weight, and symptoms. Lower grades may improve with non-surgical care, but higher grades usually need surgery.
Conservative Management (Grade I–II)
- Weight control
- Joint supplements
- Physical therapy
- Limiting jumping or rough play
- Pain medication, if needed
Dogs with mild signs often live comfortably without surgery if their condition stays stable.
Surgical Treatment (Grade II–IV)
When symptoms worsen or the patella stays out often, surgery is usually recommended.
- Trochlear sulcoplasty: Deepens the groove where the kneecap sits
- Tibial tuberosity transposition (TTT): Realigns the patellar tendon
- Soft tissue adjustments: Tighten or release tissues to improve tracking
Advanced Surgeries
- Needed for Grade III–IV
- May include bone cutting, plate fixation, or staged corrections
- Tailored to the dog's unique joint shape and deformity
Surgical plans vary, but the goal is always to keep the patella in place and restore comfortable movement.
Prognosis Based on Grade
The long-term outlook after MPL surgery is usually very good, especially when the condition is treated early and post-op care is followed closely.
Grade-Based Outcomes
- Grade I–II: Excellent prognosis; many dogs return to full activity and never need surgery
- Grade III: High success rates, but there is a slightly higher risk of reluxation or needing a second procedure
- Grade IV: Outcomes vary depending on joint damage. Dogs often improve, but some may keep a limp or limited motion
Reluxation Risk
- Occurs in about 10–21% of cases
- More common in Grade III and IV
- Risks decrease with proper rehab and weight control
Benefits of Early Treatment
- Helps prevent arthritis and joint damage
- Improves surgical success
- Shortens recovery time
With early diagnosis, a tailored surgical plan, and careful recovery, most dogs live active, pain-free lives after MPL correction.

FAQs
How do vets grade a dog’s patellar luxation?
Vets grade MPL by gently moving the kneecap during a physical exam to see how easily it slips out and whether it goes back into place. They also check how the dog walks and may use X-rays to study bone shape and joint alignment. Grades range from I (mild) to IV (severe and permanent).
What is the difference between Grade I and Grade IV MPL?
Grade I MPL is the mildest form, where the kneecap only slips out during an exam and quickly returns on its own. Dogs usually show no pain or limping. Grade IV is the most severe. The kneecap is always out, cannot be pushed back in, and the leg may look twisted or underused, often needing complex surgery.
Can Grade I MPL become worse over time?
Yes, Grade I MPL can worsen if the dog gains weight, gets injured, or has weak joint support. Over time, the kneecap may start slipping more often, leading to joint wear and pain. Regular checkups, weight control, and joint care can help prevent it from progressing to higher grades.
Is surgery always needed for Grade II MPL?
Not always. Some dogs with Grade II MPL respond well to weight control, joint supplements, and restricted activity. But if the dog shows regular limping, pain, or reduced movement, surgery may be the better option. Your vet will decide based on symptoms, age, and how the joint is behaving.
What happens if MPL is left untreated?
If MPL is not treated, it can lead to chronic pain, joint damage, and arthritis. The dog may limp more often, avoid using the leg, or develop muscle loss. In higher-grade cases, untreated MPL can result in permanent joint deformity or the need for more complex surgery later.
Are some breeds more likely to have higher-grade MPL?
Yes, small breeds like Pomeranians, Chihuahuas, Yorkies, and Toy Poodles are more likely to have MPL, and some may develop higher-grade luxation due to their bone shape and genetics. However, large breeds can also be affected. Early screening in at-risk breeds helps catch problems before they get worse.

Success Rates for Medial Patellar Luxation Surgery
Explore success rates for medial patellar luxation surgery by grade, including complications, recovery outcomes, and key factors that affect surgical success
What Is Medial Patellar Luxation (MPL)?
Medial Patellar Luxation (MPL) is a knee condition in dogs where the kneecap (patella) slips out of its normal groove on the femur. Instead of staying in place, it moves toward the inside (medial side) of the leg. This can cause pain, limping, or long-term joint damage if not treated.
Grades of MPL
- Grade I: Patella slips out but returns on its own
- Grade II: Patella comes out easily and may stay out sometimes
- Grade III: Patella is out most of the time but can be pushed back in
- Grade IV: Patella is always out and cannot be returned manually
Common Breeds and Risk Factors
- Small breeds like Pomeranians, Chihuahuas, Poodles, and Yorkies
- Genetic traits, shallow femoral grooves, or injury increase the risk
What Does MPL Surgery Involve?
Medial Patellar Luxation (MPL) surgery is done to correct the position of a dog's kneecap. When the patella keeps slipping out of place, it causes pain and changes how your dog walks. Surgery helps keep the kneecap stable and prevents long-term damage to the joint.
Goals of the Procedure
- Keep the patella inside its groove during movement
- Restore normal leg alignment and function
- Reduce pain, limping, and joint wear
- Prevent arthritis and other joint issues in the future
Common Surgical Techniques
Veterinary surgeons choose one or more techniques based on the dog’s grade of MPL and joint shape:
- Trochleoplasty: Deepens the femoral groove so the kneecap stays in place
- Tibial Tuberosity Transposition (TTT): Realigns the patellar tendon by moving a small bone piece
- Lateral Imbrication: Tightens tissue on the outer side of the joint to support the kneecap
- Medial Release: Loosens tight inner tissues that pull the patella out of place
Recovery Timeline in Brief
- Dogs can bear weight in a few days
- Activity must be limited for 6–8 weeks
- Full healing takes about 12–16 weeks, including rehab and follow-ups
Read more:
Success Rates by MPL Grade
Grade I–II: Highest Success (Up to 100%)
Surgery for Grade I and II MPL cases has the best results. These are mild forms where the kneecap may slip occasionally (Grade I) or more often but still return on its own or with help (Grade II). In both cases, joint anatomy is mostly normal.
- Success rate: Up to 100%
- Common procedures: Soft tissue tightening, medial release, trochleoplasty
- Complication rate: Very low
- Recovery time: 8–12 weeks for full return to normal function
Most dogs regain full use of the leg after healing. They walk and run normally without pain. Surgery at this stage also helps prevent arthritis or worsening joint issues in the future. In many Grade I cases, surgery isn’t even needed unless symptoms worsen.
Follow-up care includes rest, anti-inflammatory meds, and light rehab. These dogs typically do not need revision surgery, and the long-term outcome is excellent. Early treatment means faster recovery and fewer risks overall.
Grade III: High Success (90–100%) but Higher Recurrence
Grade III MPL is more advanced. The patella stays out of place most of the time but can be manually repositioned. Dogs often show more lameness, and their joint structure may need stronger correction.
- Success rate: Around 90–100%
- Common procedures: Trochleoplasty, TTT, lateral imbrication, medial release
- Complication risk: Moderate, especially reluxation
- Recovery time: 10–14 weeks, including rehab and checkups
Surgery often involves both bone and soft tissue work. In some dogs, the joint may still loosen over time, leading to partial luxation again. This is more likely if recovery is rushed or if the dog is very active during healing.
While most dogs return to near-normal movement, some may show minor stiffness or a mild limp, especially during exercise. A small number of dogs may need revision surgery later in life.
With proper surgical planning, weight control, and good rehab, most Grade III cases have strong outcomes and can return to a happy, active lifestyle.
Read more:
Grade IV: Variable Success (64–93%)
Grade IV MPL is the most severe form. The kneecap is always out of place and cannot be pushed back manually. Dogs often have serious skeletal changes, like rotated tibias or shallow grooves, which require more complex surgery.
- Success rate: Ranges from 64% to 93%
- Common procedures: TTT, deep trochleoplasty, rotational correction, staged surgeries
- Complication risk: High, especially reluxation or implant failure
- Recovery time: 12–16 weeks or longer, depending on case complexity
These surgeries are more challenging and may involve multiple steps. In some cases, staged correction is needed to slowly fix the bone alignment over time. Healing is slower, and strict rest is very important to avoid complications.
Some dogs improve but may not regain full, normal motion. A mild limp or stiffness can remain, especially in older dogs or those with long-standing luxation. However, pain relief and improved comfort are still strong outcomes.
With skilled surgery, proper follow-up, and careful rehab, many Grade IV dogs live more comfortable, mobile lives—even if their function isn't perfect.
Complication and Recurrence Rates
While most dogs recover well after Medial Patellar Luxation (MPL) surgery, there are some risks to be aware of. The chance of complications or the kneecap slipping again depends on the grade of MPL, the dog’s age, the surgeon’s technique, and how well post-surgery care is followed.
Average Rates
- Recurrence (reluxation) rate: 10–21%
- Major complication rate: 16–24%
These numbers are higher in dogs with Grade III and IV luxation, where the joint is more unstable or the bone structure is more deformed.
Common Complications
- Swelling or seroma: Fluid may collect near the incision site
- Implant issues: Pins or wires used in surgery may move or loosen
- Infection: Can happen at the wound site if not kept clean
- Joint stiffness: Especially if rest is not followed properly
- Recurrence: The patella may slip out again if healing is poor
Rare but Serious Outcomes
- Nerve damage or long-term lameness
- Poor bone healing in very active or older dogs
- Amputation (very rare): Only needed if the leg becomes non-functional due to severe infection or failure
Proper rest, weight control, and follow-up care reduce most risks.

Factors That Affect Surgical Success
Not all MPL surgeries have the same outcome. Several key factors can affect how well a dog recovers and how stable the knee stays after surgery.
Key Factors
- Age of the dog: Younger dogs tend to heal faster and adapt better. Older dogs may have slower recovery and higher arthritis risk.
- Weight/body condition: Overweight dogs have more pressure on their joints, which increases the risk of complications and slower healing.
- Other joint issues: Dogs with a torn cranial cruciate ligament (CCL) or hip problems may need more complex surgery.
- Breed-related anatomy: Some breeds have shallow grooves or bone rotation, making surgery more difficult.
- Unilateral vs bilateral surgery: Dogs with both knees affected (bilateral MPL) may take longer to recover, especially if both surgeries are done together.
Each of these factors plays a role in the dog’s outcome. A well-planned surgery combined with personalized care improves the success rate, even in more complex cases. Pre-surgical exams and imaging help identify these factors early so the treatment can be tailored to each dog’s needs.
Long-Term Outcomes and Owner Satisfaction
Most dogs that undergo MPL surgery enjoy long-lasting relief from pain and improved movement. Long-term success depends on the surgery quality and how well the dog is cared for afterward.
What Owners Can Expect Long-Term
- Pain control: Most dogs are more comfortable and pain-free after healing. Long-term pain is rare if the joint is stable.
- Activity levels: Many dogs return to normal activity—walking, running, and playing—within 3–4 months.
- Satisfaction rates: Over 90% of owners report high satisfaction with the surgery, especially in Grades I–III.
Some dogs may still show mild stiffness or avoid certain movements, especially if they had a high-grade luxation or other joint conditions. Regular exercise, weight control, and avoiding intense jumping or rough play help preserve joint health over time.
Overall, MPL surgery has a strong track record of improving quality of life. Dogs move more freely, show less pain, and become more active after recovery. When paired with proper follow-up care, most dogs remain stable for many years after surgery.

How to Maximize the Chances of a Successful Outcome
Good surgical technique is just one part of MPL recovery. What happens after surgery is just as important for a full and lasting recovery.
Key Steps for Better Results
- Post-op care: Strict crate rest for 6–8 weeks is critical. It prevents implant movement and allows the joint to heal properly.
- Rehabilitation: Gentle rehab like controlled leash walks, underwater treadmill, or physiotherapy helps regain strength and range of motion.
- Follow-ups: Regular vet checkups ensure healing is on track. X-rays may be needed to confirm bone healing and implant position.
Owners play a big role in the recovery process. Keeping the dog calm, using medications as prescribed, and following rehab steps all support better outcomes. It’s also important to avoid running, jumping, or stairs until your vet gives the all-clear.
Feeding a balanced diet and keeping your dog at a healthy weight also reduces joint stress. With the right support at home and guidance from your vet, your dog has the best chance to heal fully and return to an active, pain-free life.
Conclusion
Medial Patellar Luxation (MPL) surgery is a highly effective treatment for dogs with kneecap instability. With proper surgical planning and careful post-op care, most dogs return to normal or near-normal function. Success rates are especially high in Grade I–III cases, and even dogs with Grade IV can show major improvement.
While complications are possible, they are often manageable with early attention. Owners who follow vet instructions—especially crate rest and rehab—help their dogs heal faster and avoid reluxation. With patience and proper care, most dogs enjoy a more active, pain-free life after surgery.
FAQs
What is the average success rate for MPL surgery in dogs?
The success rate for MPL surgery is high. For Grade I–III cases, it ranges from 90% to 100%. Grade IV cases have a slightly lower success rate, between 64% and 93%, due to complex joint changes. Most dogs regain good function and live comfortably with proper care and follow-up.
Does the grade of MPL affect the surgery results?
Yes, the grade of MPL directly affects the surgery outcome. Lower grades (I–II) have simpler issues and near-perfect success. Grade III surgeries are more complex but still have high success. Grade IV often needs advanced correction and has a higher risk of complications, though many dogs still improve significantly.
What are the chances of MPL coming back after surgery?
The chance of the kneecap slipping again, called reluxation, is around 10–21%. This depends on the grade of MPL, the dog’s activity level, and how closely post-op care is followed. Proper rest, weight control, and vet follow-ups can lower this risk and help keep the knee stable.
How long does it take for a dog to recover from MPL surgery?
Most dogs begin walking within a few days but need 6–8 weeks of crate rest. Full recovery can take 3–4 months, especially for higher-grade surgeries. During this time, rehab and regular checkups help rebuild strength and ensure healing is on track.
Can my dog walk normally after MPL surgery?
Yes, most dogs can walk and even run normally after MPL surgery. Once healing is complete, they often return to normal activity levels. Minor stiffness or a limp may remain in rare cases, especially in Grade IV or older dogs, but pain and lameness usually improve.
Is MPL surgery safe for older or overweight dogs?
MPL surgery can be done safely in older or overweight dogs, but the risks are slightly higher. These dogs may heal slower or face more stress on the joint. With proper planning, pain management, and weight control, they can still have excellent results and better comfort long-term.

What to Expect After FHO Surgery in Dogs
Learn what to expect after femoral head ostectomy (FHO) surgery in dogs, including recovery timeline, care tips, and improving mobility and comfort
Femoral Head Ostectomy (FHO) is a surgery performed to relieve severe hip pain in dogs by removing the damaged head and neck of the thigh bone. This procedure stops painful bone-on-bone contact and allows the formation of a “false joint,” helping dogs move more comfortably.
Understanding the recovery process after FHO surgery is important for dog owners. Recovery involves rest, pain management, and physical therapy, all crucial to help your dog regain strength and mobility. Knowing what to expect helps you provide better care and support during healing.
Being prepared for the recovery timeline, activity restrictions, and signs to watch for ensures your dog has the best chance for a smooth, successful recovery. This knowledge also reduces stress for both you and your dog, improving overall comfort and quality of life after surgery.
Hospital Stay and Immediate Care
After Femoral Head Ostectomy (FHO) surgery, most dogs stay in the hospital for one to two days. This allows veterinarians to monitor your dog closely as they wake up from anesthesia and manage any immediate post-surgery needs.
- Length of stay: The hospital stay usually lasts 24 to 48 hours, depending on your dog’s condition and how well they recover from anesthesia.
- Pain management: Vets provide pain relief through medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and opioids if needed. Managing pain early is essential to keep your dog comfortable and encourage gentle movement.
- Medications: Your dog may also receive antibiotics to prevent infection and muscle relaxants to ease stiffness.
- Protecting the incision: To stop your dog from licking or biting the surgical site, an Elizabethan collar (cone) or alternative protective device is used. This prevents infection and helps the wound heal properly.
Close monitoring and early pain control during the hospital stay set the stage for a smoother, less painful recovery once your dog returns home.
Read more:
Post-Surgery Care at Home
After Femoral Head Ostectomy (FHO) surgery, restricted activity and cage rest are vital to ensure proper healing. Limiting your dog’s movement helps prevent strain on the surgical site and reduces the risk of complications.
- Restricted activity: Keep your dog confined to a small, quiet space or crate to avoid jumping, running, or climbing stairs for at least 6 to 8 weeks. Use a leash for short bathroom breaks only.
- Wound care: Keep the surgical incision clean and dry. Avoid bathing your dog until the vet says it’s safe. If cleaning is needed, use mild antiseptic solutions as directed by your vet, and never apply harsh chemicals.
- Watch for signs: Check the incision daily for swelling, bruising, redness, discharge, or a foul odor. Some bruising and mild swelling are normal, but worsening symptoms may indicate infection.
- Prevent licking: Use an Elizabethan collar (cone) to stop your dog from licking or biting the wound, which can cause infection and delay healing.
Careful attention to post-surgery care supports healing and helps your dog recover comfortably at home.
Recovery Timeline and Activity
Recovery after Femoral Head Ostectomy (FHO) surgery is gradual and requires careful management of activity to ensure healing and prevent complications.
- Gradual reintroduction of walking: Short, gentle leash walks usually begin about 1 to 2 weeks after surgery, depending on your vet’s advice. Start with 5 to 10 minutes and slowly increase duration as your dog gains strength and comfort.
- Activity restrictions: Avoid running, jumping, climbing stairs, or rough play for at least 6 to 8 weeks. Controlled, low-impact movement protects the surgical site and supports healing.
- Physical therapy: Rehabilitation exercises help rebuild muscle strength, improve joint mobility, and reduce stiffness. Common therapies include passive range-of-motion exercises, underwater treadmill sessions, and gentle stretching.
- Owner’s role: Following your vet’s guidance on exercise and therapy is crucial. Consistent, supervised rehab improves recovery speed and overall outcome.
With proper timing and controlled activity, most dogs regain good function and mobility within 2 to 3 months after FHO surgery. Rehabilitation plays a key role in restoring quality of life.
Monitoring and Follow-up
Scheduled veterinary visits and follow-up care are essential parts of recovery after Femoral Head Ostectomy (FHO) surgery. These appointments help your vet monitor healing progress and catch any complications early.
- Scheduled visits: Your vet will usually schedule check-ups at regular intervals, such as 2 weeks, 6 weeks, and a few months post-surgery. These visits allow close monitoring of your dog’s recovery and adjustment of treatment plans if needed.
- X-rays: Follow-up X-rays help the vet assess the surgical site, check the formation of the “false joint,” and ensure there are no signs of infection or complications. X-rays provide valuable information about bone healing and joint stability.
- What vets look for: During exams, vets check your dog’s pain levels, mobility, muscle strength, and incision healing. They also evaluate the range of motion and watch for signs of swelling, infection, or abnormal joint movement.

Signs Your Dog Might Need Femoral Head Ostectomy
Learn the common signs your dog may need femoral head ostectomy surgery to relieve hip pain and improve mobility for a better quality of life
If your dog is showing signs of pain or trouble moving their hip, it might be time to consider a surgery called Femoral Head Ostectomy (FHO). This surgery helps dogs with serious hip problems feel better and walk more easily. Knowing the signs your dog needs FHO can help you act early and improve their quality of life.
Signs Your Dog Might Need Femoral Head Ostectomy
Recognizing the signs early helps ensure your dog receives timely treatment for painful hip conditions that may require Femoral Head Ostectomy (FHO) surgery.
1. Difficulty Walking or Limping
Limping or difficulty walking is one of the most obvious signs your dog might need FHO surgery. When the hip joint is painful or damaged, your dog will try to avoid putting weight on the affected leg.
- Your dog may limp continuously or only after exercise.
- Favoring one leg over the other helps reduce pressure and pain in the hip.
- Difficulty walking may present as slow, hesitant steps or reluctance to move.
This limping indicates that the hip joint is not functioning properly due to pain, arthritis, fracture, or other damage. Persistent limping despite rest or medication is a strong sign that surgical intervention like FHO could be necessary.
2. Abnormal Gait or Favoring One Leg
An abnormal gait means your dog’s walking pattern changes because of discomfort or weakness. Dogs with hip problems may shift their weight unevenly, causing visible changes in how they move.
- Your dog may “swing” the affected leg or take shorter steps on that side.
- Uneven weight distribution may cause limping or skipping.
- The gait may look unbalanced or awkward, especially after activity.
These changes result from pain or instability in the hip joint. Abnormal gait often worsens over time and is a clear signal to consult your vet for possible surgery.
3. Loss of Weight-Bearing on the Affected Leg
Loss of weight-bearing means your dog refuses to put any weight on the painful leg. This is a severe sign of hip dysfunction and pain.
- Your dog may hold the leg completely off the ground while standing or walking.
- This can occur suddenly or develop gradually with worsening discomfort.
- Loss of weight-bearing leads to muscle weakness and further mobility issues.
When your dog stops using the leg due to pain, it often indicates advanced joint damage requiring surgical treatment such as FHO for pain relief and function restoration.

- Hip pain reduces interest in walks, play, and normal activities.
Ongoing pain means conservative treatments are not controlling the condition, and surgery may be the best option to restore comfort and mobility.
5. Decreased Activity or Reluctance to Play
Changes in activity level are often one of the first signs owners notice when their dog is in pain.
- Your dog may avoid running, jumping, or climbing stairs.
- Reduced playfulness and slower movements indicate discomfort.
- Reluctance to exercise can lead to weight gain and muscle loss.
This behavior change shows your dog is trying to avoid pain, which may signal the need for surgical intervention like FHO.
6. Stiffness in the Hip Joint, Especially After Rest
Stiffness after rest or sleep is common in dogs with hip joint problems.
- Your dog may be slow to stand or walk after naps.
- The hip may feel tight or rigid, limiting movement temporarily.
- Stiffness often improves with gentle activity but returns after resting.
This stiffness indicates joint inflammation or damage, which may require surgery if it significantly impacts mobility.
7. Pain When the Hip Is Manipulated or Touched
During veterinary exams, pain responses when the hip is moved or touched can confirm joint problems.
- Vets check for tenderness by gently manipulating the hip joint.
- Pain during these tests often correlates with arthritis, fractures, or hip dysplasia.
- A painful response supports the need for further treatment or surgery.
This exam finding helps vets decide if FHO surgery is appropriate for your dog’s condition.
8. Limited Range of Motion in the Hip
A reduced ability to move the hip joint shows stiffness and pain.
- Your dog may struggle to fully extend or flex the leg.
- Limited motion causes difficulty in walking, running, or climbing.
- This restriction often worsens over time without treatment.
Limited range of motion is a key symptom indicating severe joint damage that may benefit from FHO surgery.
9. Muscle Loss or Atrophy in the Affected Leg
Muscle wasting happens when a dog stops using the painful leg regularly.
- You may notice the leg looks thinner or weaker compared to the other side.
- Muscle loss reduces joint support and slows recovery.
- Atrophy often signals chronic discomfort and long-term mobility issues.
Muscle loss is a serious sign that conservative care is no longer enough, and surgical options should be considered.

When Is FHO Surgery Recommended for Dogs?
Discover when Femoral Head Ostectomy (FHO) surgery is recommended for dogs, including common conditions and signs needing surgical care
Understanding FHO Surgery
Femoral Head Ostectomy (FHO) is a surgical procedure where the head and neck of the thigh bone (femur) are removed. This surgery is done to relieve severe pain caused by hip problems like arthritis, fractures, or hip dysplasia.
FHO helps dogs by eliminating the painful bone-on-bone contact inside the hip joint. After surgery, the body forms a “false joint” made of fibrous tissue, which cushions the area and allows more comfortable movement. Although it’s not a normal joint, this new structure reduces pain and improves mobility.
This surgery is often recommended when other treatments like medication or physical therapy have not worked. It allows dogs to regain the use of their leg and live with less discomfort. FHO can be especially helpful for dogs with severe hip damage or those who cannot have more complex surgeries like total hip replacement.
How Veterinarians Diagnose the Need for FHO Surgery
Veterinarians use a combination of physical exams and diagnostic imaging to determine if Femoral Head Ostectomy (FHO) surgery is needed for your dog.
- Physical exam: The vet will assess your dog’s hip joint by checking for pain, swelling, decreased range of motion, and signs of lameness or instability. They will observe how your dog walks and moves to identify discomfort or limited mobility.
- Diagnostic imaging: X-rays are essential to see the condition of the hip joint, including bone damage, arthritis, fractures, or deformities. These images help confirm the diagnosis and guide treatment decisions.
- Signs and symptoms: Dogs showing severe hip pain, persistent limping, difficulty standing or walking, and poor response to medication or physical therapy are often evaluated for surgery.
- Additional tests: In some cases, advanced imaging like CT or MRI may be used for detailed views of the joint structures.
After evaluating these findings along with your dog’s age, size, and overall health, the vet decides if FHO surgery is the best option to relieve pain and improve mobility. Early diagnosis helps plan effective treatment and improve outcomes.

Medical Conditions That Indicate FHO Surgery
Femoral Head Ostectomy (FHO) surgery is often recommended for dogs suffering from specific medical conditions that cause severe hip pain and joint damage.
- Hip dysplasia and severe arthritis: Hip dysplasia is a genetic condition where the hip joint forms abnormally, leading to arthritis and chronic pain. When arthritis becomes severe, FHO can relieve pain by removing the damaged femoral head.
- Traumatic hip injuries: Fractures or dislocations of the femoral head or neck caused by accidents or trauma may require FHO if the bones cannot be repaired. This surgery helps restore comfort and function.
- Legg-Calve-Perthes disease: This condition causes the femoral head to deteriorate (necrosis) due to poor blood supply. FHO removes the damaged bone to eliminate pain and improve mobility.
- Degenerative joint disease in older dogs: Age-related joint wear and tear can cause chronic hip pain. When other treatments fail, FHO can improve quality of life by reducing discomfort and increasing mobility.
Your vet will assess these conditions through exams and imaging to determine if FHO is the best surgical option for your dog’s specific needs.
When Conservative Treatments Are Not Enough
Conservative treatments like medication, rest, and physical therapy are often the first steps in managing hip problems in dogs. However, these approaches may not always provide enough relief.
- Medication failure: Pain relievers and anti-inflammatory drugs can reduce discomfort temporarily, but if your dog continues to show pain or limping, medication alone may not be sufficient.
- Rest and activity modification: Limiting activity can help reduce stress on the hip joint, but persistent discomfort despite rest indicates the need for further intervention.
- Physical therapy limitations: While rehab exercises strengthen muscles and improve joint function, some dogs do not respond well enough to prevent ongoing pain or mobility issues.
When pain and limited mobility continue despite these treatments, it suggests the hip joint damage is severe. At this stage, Femoral Head Ostectomy (FHO) surgery may be recommended to relieve pain and improve quality of life.
Your vet will carefully evaluate your dog’s response to conservative care before suggesting surgery, ensuring that FHO is the best option for lasting relief and better mobility. Early surgical intervention can prevent further decline and discomfort.

Ideal Candidates for FHO Surgery
Femoral Head Ostectomy (FHO) surgery is best suited for certain groups of dogs based on their size, health, and response to other treatments.
- Small to medium-sized dogs: FHO works especially well for dogs under 50 pounds. Their lighter weight allows the “false joint” formed after surgery to support movement effectively, leading to better recovery and mobility.
- Dogs with poor response to previous treatments: If your dog has had medication, physical therapy, or other hip surgeries without sufficient pain relief or improvement, FHO may be the next best step to address ongoing discomfort.
- Dogs with significant reduction in quality of life: When hip pain severely limits your dog’s ability to walk, run, play, or enjoy daily activities, surgery can greatly improve comfort and function.
Vets consider factors like your dog’s age, overall health, activity level, and severity of joint damage when recommending FHO. While FHO may not be suitable for every dog, it offers excellent pain relief and improved mobility for many. Discussing your dog’s specific situation with your vet helps ensure the best treatment choice.
FHO Surgery as an Alternative to Total Hip Replacement
Total hip replacement (THR) is a highly effective surgery that replaces the entire hip joint with an artificial implant. However, THR may not always be feasible or affordable for every dog and owner.
- When THR is not feasible: Some dogs, especially smaller breeds or those with certain health issues, may not be good candidates for THR due to surgical complexity or recovery demands.
- Cost considerations: THR is usually more expensive than Femoral Head Ostectomy (FHO), making FHO a practical option for many owners seeking pain relief for their dogs.
FHO is a less invasive salvage procedure that removes only the damaged femoral head and neck, reducing pain and improving mobility without the need for artificial implants.
- Benefits of FHO: It generally has a shorter surgery time, fewer risks, and a good success rate, especially in smaller dogs. The formation of a “false joint” allows dogs to regain comfortable movement.
While THR can provide better long-term joint function for some, FHO remains a valuable, effective alternative for dogs needing pain relief with fewer surgical demands.

What Is Femoral Head Ostectomy in Dogs?
Learn about femoral head ostectomy (FHO) surgery in dogs, its purpose to relieve hip pain, and how it helps improve mobility and quality of life
What Is Femoral Head Ostectomy (FHO)?
Femoral Head Ostectomy (FHO) is a surgical procedure for dogs where the head of the thigh bone (femur) is removed. This surgery is done to relieve severe pain caused by hip problems. Without the femoral head, the painful bone-on-bone contact in the hip joint stops, which reduces discomfort.
FHO is usually performed when other treatments, like medication or therapy, have not helped. Common reasons for FHO include hip dysplasia, severe arthritis, fractures, or injury that damage the hip joint. The main goal of the surgery is to improve your dog’s comfort and quality of life by stopping the pain from a damaged hip.
After surgery, the body forms a “false joint” where the femoral head was removed. This new joint allows your dog to move more comfortably without the usual pain caused by the damaged bone. FHO can be very effective in helping dogs regain mobility.
Why Do Dogs Need FHO Surgery?
Femoral Head Ostectomy (FHO) surgery is recommended when dogs have severe hip problems that cause pain and limit movement. It is often chosen when other treatments like medication or physical therapy do not provide enough relief.
Common causes that lead to FHO surgery include:
- Hip dysplasia: A genetic condition where the hip joint develops abnormally, causing pain and arthritis.
- Severe arthritis: Wear and tear in the hip joint that causes inflammation, stiffness, and chronic pain.
- Trauma or injury: Damage from accidents, such as fractures or dislocations, that severely affect the hip joint.
- Fractures: Broken bones in the femoral head or neck that cannot be repaired easily.
FHO is usually recommended when these conditions cause persistent pain and reduce your dog’s quality of life. It is often chosen over hip replacement surgery for smaller dogs, or when the cost or complexity of other surgeries is not suitable.
The surgery helps relieve pain by removing the damaged bone, allowing your dog to regain mobility and live more comfortably. Your vet will decide if FHO is the best option based on your dog’s age, size, and condition severity.
Read more:
How Does FHO Surgery Work?
Femoral Head Ostectomy (FHO) surgery involves removing the femoral head and neck—the round top part of the thigh bone that fits into the hip socket. By removing these damaged bone parts, the surgery eliminates painful bone-on-bone contact in the hip joint.
After surgery, the body naturally forms a “false joint” made of fibrous tissue and muscle in place of the removed bone. This false joint acts like a cushion, allowing the leg to move smoothly without bone grinding or pain. Although it’s not a normal joint, this fibrous tissue provides enough support for comfortable movement.
Inside the body, muscles and connective tissue around the hip adapt to stabilize the new joint area. Over weeks to months, scar tissue strengthens and improves flexibility, helping your dog regain use of the leg.
Because the bone is removed, the hip joint no longer causes pain from arthritis, fractures, or injury. The false joint helps your dog move more freely and reduces discomfort, improving quality of life. Proper post-surgery rehab is essential to build muscle and support this new joint.
Who Is a Good Candidate for FHO?
Femoral Head Ostectomy (FHO) is a good option for many dogs, especially those who suffer from severe hip pain that limits their mobility. Typically, smaller dogs weighing less than 50 pounds are ideal candidates because their lighter weight makes it easier for the false joint to support movement. However, dogs of any size or age may benefit from FHO depending on their condition.
Good candidates usually include dogs with:
- Severe hip arthritis causing chronic pain
- Hip dysplasia with joint damage
- Fractures or trauma to the femoral head or neck that cannot be repaired
- Poor response to medication or conservative treatments
FHO is often preferred over more complex surgeries like total hip replacement for younger dogs, smaller breeds, or when cost or health concerns make other options less suitable.
Your vet will evaluate your dog’s age, weight, activity level, and overall health to determine if FHO is the best solution. The goal is to relieve pain and improve mobility, giving your dog a better quality of life.

What to Expect During the Surgery
Femoral Head Ostectomy (FHO) surgery is performed under general anesthesia to ensure your dog is completely unconscious and pain-free. Before the procedure, your vet will conduct a full health check and blood tests to make sure your dog is fit for anesthesia.
During surgery, the vet makes an incision near the hip to access the joint. The femoral head and neck—the top part of the thigh bone—are carefully removed. The area is cleaned, and the muscles and tissues around the hip are sutured to help form the “false joint.” The skin is then closed with stitches or staples.
The surgery usually takes about one to two hours, depending on the dog’s size and condition. After surgery, your dog will be monitored closely as they wake up from anesthesia.
Immediate post-surgery care includes pain management, preventing infection, and limiting movement to protect the surgical site. Your vet will provide detailed instructions on medications and activity restrictions to help your dog heal safely and comfortably.
Recovery and Rehabilitation After FHO
Recovery after Femoral Head Ostectomy (FHO) requires patience and careful management. Physical therapy and gradual weight-bearing are key to helping your dog regain strength and mobility.
- Physical therapy: Helps rebuild muscles around the hip and improve joint movement. Without it, muscle loss and stiffness can slow recovery.
- Gradual weight-bearing: Start with short, gentle walks as your dog feels comfortable. Slowly increase activity following your vet’s guidance.
- Recovery timeline: Most dogs heal significantly within 6 to 12 weeks, but full improvement may take several months. Regular vet visits track progress.
- Owner’s role: Follow all activity restrictions and medication schedules. Assist with home exercises and provide a safe, calm environment.
Your care and attention during recovery greatly influence the outcome. By supporting your dog with controlled activity and rehab, you help ensure a smoother, faster recovery and improve their long-term quality of life.

Expected Outcomes and Benefits
Femoral Head Ostectomy (FHO) surgery offers significant benefits for dogs suffering from severe hip pain. The primary outcome is pain relief by removing the damaged femoral head, which stops the painful bone-on-bone contact in the hip joint.
- Pain relief: Most dogs experience a noticeable reduction in pain soon after surgery, allowing them to move more comfortably.
- Improved mobility: As the false joint forms and muscles strengthen, dogs regain better use of the leg, improving walking, running, and daily activities.
- Adaptation: Dogs naturally adjust to the new joint structure, often returning to an active and happy lifestyle.
The long-term prognosis for most dogs after FHO is excellent, especially when combined with proper rehabilitation and care. While the false joint is not a true hip replacement, it provides enough support for normal movement without pain. Small to medium-sized dogs usually recover faster and have better outcomes, but dogs of all sizes can benefit.
Overall, FHO improves quality of life by eliminating chronic pain and increasing mobility, allowing dogs to enjoy their favorite activities again.
Potential Risks and Complications
While Femoral Head Ostectomy (FHO) surgery is generally successful, there are potential risks and complications to be aware of during recovery.
- Muscle atrophy: Reduced use of the leg after surgery can lead to muscle loss around the hip. Without proper physical therapy, this can slow recovery and reduce strength.
- Reduced range of motion: Scar tissue and stiffness may limit how much your dog can move the leg if rehab is insufficient.
- Infection: Like any surgery, there is a risk of infection at the surgical site, which requires prompt veterinary treatment.
- Lameness or limping: Some dogs may continue to limp or show uneven weight-bearing after surgery, especially if healing is slow or if complications occur.
- Nerve or blood vessel injury: Though rare, surgery may affect nearby nerves or vessels, causing additional issues.
Follow-up care is essential to minimize these risks. Regular veterinary visits allow early detection and management of problems. Strict adherence to activity restrictions, medication schedules, and rehabilitation exercises supports healing and reduces complications. With careful monitoring and care, most dogs recover well and regain comfortable mobility.
Alternatives to FHO Surgery
Femoral Head Ostectomy (FHO) is one option for treating severe hip problems, but there are alternatives depending on your dog’s condition and needs.
- Conservative treatments: These include pain medications, anti-inflammatory drugs, physical therapy, weight management, and joint supplements. Conservative care is often tried first for mild to moderate cases or when surgery isn’t an option due to age or health. While it may help reduce pain, it usually does not fix severe joint damage.
- Total hip replacement (THR): This surgery replaces the entire hip joint with an artificial implant. THR is more complex and expensive but can provide better long-term function and mobility, especially for larger or active dogs. It is often preferred when joint damage is severe but the dog is healthy enough for major surgery.
Choosing between FHO and alternatives depends on factors like your dog’s size, age, activity level, and overall health. FHO may be better for smaller dogs or those who cannot undergo extensive surgery. THR can offer improved outcomes for some dogs but requires a longer recovery. Your vet will help determine the best option based on your dog’s specific situation.

How Veterinarians Diagnose the Need for FHO
Veterinarians use a combination of physical exams and diagnostic tools to determine if Femoral Head Ostectomy (FHO) surgery is necessary for your dog.
- Physical examination: The vet assesses your dog’s hip joint by checking for pain, swelling, range of motion, and signs of instability or lameness. They observe how your dog walks and moves to identify discomfort or limited mobility.
- X-rays: Radiographs help vets see the condition of the hip joint, including bone damage, arthritis, fractures, or deformities. X-rays are essential for confirming the diagnosis and planning treatment.
- Additional tests: In some cases, vets may use advanced imaging like CT scans or MRI to get a detailed view of the joint structures.
After evaluating the exam results and imaging, the vet considers your dog’s age, size, overall health, and lifestyle. They weigh the benefits and risks of surgery versus other treatments.
If pain and joint damage are severe, and conservative treatments haven’t helped, the vet may recommend FHO as the best option to relieve pain and improve mobility. Clear communication with your vet helps ensure the right decision for your dog’s care.
Conclusion
Femoral Head Ostectomy (FHO) is a valuable surgery that helps dogs suffering from severe hip pain caused by conditions like arthritis, fractures, or hip dysplasia. By removing the damaged femoral head, FHO stops painful bone-on-bone contact and allows the formation of a new “false joint.” This procedure significantly reduces pain and improves mobility, helping dogs regain comfort and quality of life.
Recovery requires patience, physical therapy, and owner support, but most dogs adapt well and return to active lives. FHO is often recommended for smaller dogs or when other treatments fail. If your dog shows signs of hip pain or mobility issues, consult your vet early. Understanding FHO can help you make informed decisions to give your dog the best care and a happier, pain-free future.
FAQs About Femoral Head Ostectomy (FHO) in Dogs
What is Femoral Head Ostectomy (FHO) surgery?
FHO is a procedure where the top part of the thigh bone (femoral head) is removed to relieve pain caused by hip joint damage. It stops bone-on-bone contact and helps dogs move more comfortably by forming a “false joint” made of fibrous tissue.
When is FHO surgery recommended for dogs?
FHO is usually recommended for dogs with severe hip pain from arthritis, fractures, hip dysplasia, or trauma, especially when conservative treatments don’t help. It’s often preferred for smaller dogs or when total hip replacement is not suitable.
How long does it take for a dog to recover from FHO?
Recovery typically takes 6 to 12 weeks. During this time, physical therapy and gradual weight-bearing help rebuild muscle and improve mobility. Full recovery may take several months, depending on the dog’s size and health.
What are the risks of FHO surgery?
Possible risks include muscle loss, reduced joint motion, infection, and continued limping. Following post-surgery care and rehabilitation instructions closely helps minimize these risks and improves outcomes.
Can large dogs have FHO surgery?
Yes, large dogs can have FHO, but recovery may be more challenging because of their weight. Vets may recommend alternative treatments or total hip replacement for better long-term results in bigger dogs.
How does the “false joint” work after FHO?
After surgery, fibrous tissue forms where the femoral head was removed, creating a “false joint.” This tissue cushions the hip, allowing pain-free movement even without a true ball-and-socket joint, helping dogs regain function.

How to Tell If Your Dog Has a Medially Luxating Patella
Learn how to recognize signs of medial patellar luxation in dogs early, including limping, clicking sounds, and changes in gait for timely treatment
What Is Medial Patellar Luxation in Dogs?
Medial Patellar Luxation (MPL) is a condition where the kneecap (patella) slips out of its normal groove toward the inside of a dog’s leg. This causes the knee joint to become unstable, leading to pain, limping, and difficulty walking. MPL is especially common in small and toy dog breeds but can affect dogs of any size.
MPL matters because if left untreated, it can cause long-term joint damage, arthritis, and chronic pain. The slipping kneecap puts extra stress on the knee, making movement uncomfortable and sometimes causing your dog to avoid using the leg.
Early detection is very important for your dog’s health and comfort. Recognizing signs like limping, skipping steps, or holding up a leg allows you to seek veterinary care sooner. Early treatment can reduce pain, prevent further damage, and improve your dog’s quality of life. Keeping a close eye on your dog’s movement helps catch MPL before it worsens.
Common Signs That Your Dog May Have MPL
Here are some common signs that can help you identify if your dog may be suffering from medial patellar luxation (MPL).
1. Limping or Skipping Steps
Limping or skipping steps is one of the earliest signs your dog might have medial patellar luxation (MPL). When the kneecap slips out of place, your dog may feel pain or instability, causing uneven movement.
- Watch for your dog lifting a leg briefly while walking or running.
- Notice if your dog skips steps or hops on one leg suddenly.
- Limping can be subtle at first and may only happen after exercise or prolonged activity.
If you see your dog favoring one leg or walking unevenly, it’s a sign to check with your vet. Early limping or skipping indicates discomfort or instability in the knee, which can worsen if untreated. Tracking these patterns helps you catch MPL early and get your dog the care needed to prevent long-term damage.
2. Intermittent or Persistent Lameness
Lameness means your dog is limping or not using a leg normally. It can be intermittent (comes and goes) or persistent (constant). Both can be warning signs of MPL.
- Intermittent lameness often appears after exercise or activity when the kneecap slips out temporarily.
- Persistent lameness means ongoing pain or instability in the knee, which needs urgent attention.
- Your dog may hold up the leg or limp constantly if the condition is severe.
Recognizing when lameness changes from occasional to frequent is important. Early veterinary diagnosis can help treat mild lameness before it becomes severe. Persistent lameness might indicate worsening MPL or other complications. Watching how often your dog limps and seeking veterinary advice quickly improves treatment outcomes.
3. Abnormal Gait or Skipping Leg Movement
An abnormal gait means your dog’s walk or run looks different from normal. In dogs with MPL, this often shows as unusual skipping or jerky leg movement.
- Your dog may appear to skip or hop instead of walking smoothly.
- The affected leg might move differently, seeming stiff or shaky.
- This irregular movement happens because the kneecap slips, causing discomfort or instability.
This gait change may be subtle at first and can be mistaken for other issues. Watching carefully during walks or play helps spot unusual leg movements. Early detection allows for prompt treatment to restore normal walking patterns and reduce pain.
4. Audible Clicking or Popping Sounds
Clicking or popping sounds from your dog’s knee are signs that the kneecap is moving abnormally. These sounds happen when the patella slips out of its groove and snaps back.
- You might hear a faint “click” when your dog walks, runs, or moves the leg.
- These noises show joint instability and possible damage to soft tissues.
- Not all dogs make these sounds, but if you hear them often, it’s a sign to get a vet check.
Listening for these sounds during activity or when your dog moves the leg gently can provide clues about MPL. Early veterinary diagnosis helps prevent joint damage from frequent slipping.
5. Visible or Palpable Slipping of the Kneecap
Sometimes, you can see or feel the kneecap slipping out of place. This popping or luxation happens when the kneecap moves out of its normal groove on the thigh bone.
- Gently feel your dog’s knee when the leg is bent and straightened to check for slipping.
- You might see the kneecap visibly move or pop to the side during leg movement.
- If unsure, have a vet perform this test to avoid causing pain or injury.
Feeling or seeing the patella slip is a clear sign of MPL. If you notice this, it’s important to visit your vet for a full examination and diagnosis.
6. Holding Up the Leg or Avoiding Weight Bearing
Dogs with MPL often hold up the affected leg or avoid putting weight on it to relieve pain or discomfort.
- Your dog may lift the leg while standing or walking, especially after activity.
- Avoidance of weight bearing is a common way dogs protect an injured or painful knee.
- This behavior can be temporary or frequent depending on MPL severity.
If your dog regularly holds up a leg or refuses to walk on it, it’s a strong sign of knee pain. Early vet evaluation helps manage discomfort and improves healing.
7. Difficulty or Reluctance to Jump, Run, or Climb Stairs
Changes in your dog’s activity level, like difficulty or unwillingness to jump, run, or climb stairs, often point to knee problems like MPL.
- Your dog may avoid stairs or hesitate before jumping onto furniture or into cars.
- Running or playing less than usual can indicate discomfort during high-impact activities.
- These behavioral changes help protect the painful knee from stress.
Noticing reluctance to be active is important for early MPL detection. Discussing these changes with your vet can lead to timely diagnosis and treatment.
8. Swelling or Pain Around the Knee Joint
Swelling or pain near the knee joint may develop with MPL due to inflammation from repeated kneecap slipping.
- Look for visible swelling, warmth, or tenderness around the knee.
- Your dog might lick or chew the knee area more than usual.
- Pain signs include limping, whining, or reluctance to move.
Swelling and pain indicate irritation or early joint damage. Prompt veterinary care can reduce inflammation and prevent progression.
9. Changes in Behavior Like Reluctance to Play or Exercise
Discomfort from MPL often causes changes in your dog’s behavior, such as reduced playfulness or exercise reluctance.
- Your dog may become less active or hide more than usual.
- Decreased interest in walks, toys, or interaction can signal pain.
- These subtle mood changes are important clues to underlying knee issues.
Recognizing these behavior shifts early helps you seek veterinary care and improve your dog’s comfort and quality of life.
How MPL Symptoms Can Worsen Over Time
If medial patellar luxation (MPL) is not treated, your dog’s symptoms can get worse and cause more serious problems.
- More frequent kneecap slipping: The patella may move out of place more often, causing pain and joint instability.
- Joint damage and arthritis: Repeated slipping can wear down cartilage and bones, leading to arthritis. This causes swelling, stiffness, and long-term pain.
- Increased limping or holding up the leg: Your dog may limp more or avoid using the affected leg due to discomfort.
- Posture and gait changes: To reduce pain, your dog might change how they stand or walk, which can cause muscle loss and strain on other legs.
- Both knees affected: Sometimes MPL develops in both legs, worsening mobility and quality of life.
Monitoring your dog’s symptoms closely helps catch these changes early. Watch for increased limping, reduced activity, or changes in behavior. Early vet care can reduce pain, prevent joint damage, and improve your dog’s chances of a happy, active life.
How to Monitor Your Dog’s Mobility and Pain at Home
Monitoring your dog’s mobility and pain at home helps you track their condition and notice any worsening signs early. Regular observation lets you provide important information to your vet for better care.
- Watch your dog’s walking: Look for limping, skipping steps, or difficulty standing up. Notice if your dog favors one leg or hesitates to move.
- Observe activity levels: Pay attention to changes in how much your dog wants to play, run, or climb stairs. Reduced activity can signal pain or discomfort.
- Check for stiffness: Notice if your dog is stiff or slow to get moving after resting or sleeping.
- Look for pain behaviors: Whining, licking the knee, or sudden stops during movement may show discomfort.
- Examine posture: Watch for changes in how your dog holds their leg or stands.
Keep a simple journal to record daily observations, noting any new or worsening symptoms. Include details about when symptoms appear, their severity, and any triggers like exercise. Sharing this information with your vet helps tailor treatment and improves your dog’s care. Regular monitoring is key to managing MPL effectively.
When to Seek Veterinary Care for Suspected MPL
Knowing when to seek veterinary care for suspected medial patellar luxation (MPL) is crucial to protect your dog’s health and comfort. Early veterinary attention can prevent worsening damage and reduce pain.
- Sudden or severe limping: If your dog starts limping suddenly or cannot put weight on a leg, it needs immediate vet care.
- Persistent or worsening lameness: Continuous limping or increasing difficulty walking are signs of serious knee issues.
- Visible swelling or redness: Swelling, heat, or redness around the knee may indicate inflammation or infection.
- Audible clicking or popping: Hearing frequent clicking sounds from the knee can signal instability needing professional evaluation.
- Reluctance to move or play: A sudden decrease in activity or reluctance to jump, run, or climb stairs suggests discomfort.
Early diagnosis allows your vet to assess the severity of MPL and recommend the best treatment, whether conservative care or surgery. Prompt treatment reduces pain, slows joint damage, and improves your dog’s quality of life. Don’t wait for symptoms to worsen—early veterinary care is key to a better outcome.
FAQs About How to Tell If Your Dog Has a Medially Luxating Patella

Recovery After Medial Patellar Luxation Surgery in Dogs
Discover the typical recovery timeline, care tips, and pain management after medial patellar luxation surgery to help your dog heal safely and comfortably
Typical Recovery Timeline After MPL Surgery
After medial patellar luxation surgery, your dog’s healing usually takes about 6 to 8 weeks. During this time, the knee joint repairs itself, and your dog gradually regains strength and mobility.
In the first few days, your dog may feel sore and show limited movement. Pain and swelling are normal but should improve with medication prescribed by the vet. It’s important to keep your dog calm and limit activity to help the knee heal.
Here’s what to expect during recovery:
- Weeks 1-2: Rest and restricted movement are critical. Use a leash for short bathroom breaks only. Apply cold packs if recommended by your vet to reduce swelling.
- Weeks 3-4: Your dog may start gentle walking or physical therapy exercises. Muscle strengthening begins carefully to support the knee.
- Weeks 5-6: Gradual increase in activity, including short walks and controlled play. Monitor for any signs of pain or limping.
- Week 7-8: Most dogs regain good function and strength. Your vet will check progress and may clear your dog for normal activities.
Following your vet’s recovery plan closely improves healing and helps prevent complications.
Post-Surgery Care and Activity Restrictions
After medial patellar luxation surgery, strict rest is essential to help your dog heal properly. Rest allows the repaired tissues and bones to recover without stress. Limiting movement prevents the kneecap from slipping again or causing damage during the healing process.
To keep your dog calm, restrict them to a small, quiet area like a crate or a room. Use a leash when taking them outside for bathroom breaks. Avoid letting your dog run, jump, or play freely during the first 6 to 8 weeks after surgery.
Certain activities should be avoided because they put extra pressure on the knee:
- Jumping on and off furniture or into cars
- Running or playing fetch
- Climbing stairs or steep slopes
These movements can strain the healing joint, cause pain, and slow recovery. Instead, focus on short, controlled walks as advised by your vet. Following these activity restrictions helps reduce complications and supports a smoother, faster recovery for your dog.
Managing Pain and Inflammation
Managing pain and inflammation after medial patellar luxation surgery is key to your dog’s comfort and healing. Vets commonly prescribe pain relief medications like non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and swelling. These medicines help your dog feel more comfortable and encourage gentle movement during recovery.
Sometimes, vets may also recommend mild painkillers or muscle relaxants if the pain is more severe. It’s important to give all medications exactly as prescribed and never use human pain medicines without veterinary advice.
Cold therapy is another effective way to control swelling and reduce pain after surgery. Applying cold packs or ice wrapped in a towel to the knee for 10-15 minutes, several times a day, can help shrink blood vessels and lower inflammation. Cold therapy is most useful in the first 48-72 hours after surgery.
Supportive treatments like gentle massage or physical therapy may also be suggested by your vet to improve circulation and promote healing. Together, these methods reduce discomfort and support a smoother recovery process for your dog.
Wound Care and Monitoring
Proper wound care after medial patellar luxation surgery is crucial to avoid infection and help healing. Keeping the surgical site clean and watching for problems supports a smooth recovery.
- Check the incision daily: Look for redness, swelling, warmth, discharge, or bad smell. Mild swelling and bruising are normal, but worsening signs need a vet’s attention.
- Keep the area dry and clean: Avoid bathing your dog until the vet allows it. If cleaning is needed, gently use a mild antiseptic or saline with a clean cloth or cotton swab. Avoid harsh chemicals like alcohol.
- Prevent licking or chewing: Use an Elizabethan collar (cone) or other protective devices to stop your dog from irritating the wound. Licking can cause infection and delay healing.
- Do not touch stitches or staples: Let your vet remove them during follow-up visits, usually 10 to 14 days after surgery.
Following these steps carefully helps detect issues early and keeps the wound healthy for faster healing. Regular vet check-ups ensure the recovery is progressing well.
Physical Rehabilitation and Exercise
Physical rehabilitation plays a key role in helping your dog recover after medial patellar luxation surgery. Gentle exercises rebuild muscle strength, improve joint mobility, and support the healing knee. Without rehab, muscles can weaken and the joint may become stiff, slowing recovery.
Rehabilitation exercises usually start once the initial healing phase is over, often around 2 to 4 weeks after surgery. These exercises focus on gentle stretching, controlled leg movements, and muscle strengthening to restore normal function. A vet or veterinary physical therapist can guide you with safe, effective exercises tailored to your dog’s condition.
Gradual Reintroduction of Controlled Exercise
Gradual reintroduction of controlled exercise is essential to avoid overloading the healing knee. Short, slow walks on a leash are usually allowed first, increasing in length and intensity over several weeks. Running, jumping, and rough play should be avoided until your vet confirms the knee is strong enough.
Here’s how to safely increase activity during recovery:
- Start with brief leash walks of 5-10 minutes
- Slowly increase walk time and gentle movements
- Monitor your dog for signs of pain or limping
- Follow your vet’s advice on physical therapy sessions
Proper rehab and controlled exercise help your dog regain strength, improve joint stability, and return to normal activity safely and comfortably.
Supporting Recovery Through Diet and Environment
Dietary Considerations and Weight Management
Maintaining a healthy weight is very important during your dog’s recovery after medial patellar luxation surgery. Extra weight puts pressure on the healing knee, causing pain and slowing recovery. A balanced diet supports tissue repair and overall health.
- Control calories: Avoid high-calorie treats and table scraps that cause weight gain.
- Vet-recommended diet: Follow your vet’s advice for a diet rich in vitamins and minerals but low in excess calories.
- Gradual weight loss: If your dog is overweight, lose weight slowly under veterinary guidance to reduce joint stress.
- Nutritional support: Proper nutrients help the body heal faster and keep your dog comfortable.
Keeping your dog at a healthy weight lowers the risk of arthritis and helps the knee heal well.
Home Environment Adjustments
Making changes at home helps keep your dog safe and comfortable while recovering.

Regular check-ups are essential for tracking progress and preventing complications, ensuring your dog recovers safely and fully.
Recognizing Possible Complications
Watch for signs like increased redness, swelling, discharge, or heat around the incision, which may indicate infection. If your dog suddenly limps more or holds the leg differently, the kneecap might have slipped again (patellar reluxation). Other signs include worsening pain, fever, or loss of appetite. Early detection of complications allows prompt veterinary care to avoid further damage and pain.
When to Contact the Vet
Contact your vet immediately if your dog shows severe limping, refuses to use the leg, or if you see swelling or discharge at the surgery site. Also, urgent care is needed if your dog shows signs of infection, such as fever or lethargy. Early communication with your vet helps manage issues quickly and supports a smoother recovery.
Owner’s Role in Successful Recovery
Your role as a dog owner is crucial for a smooth and successful recovery after medial patellar luxation surgery. Following your vet’s care instructions carefully directly affects how well and how quickly your dog heals.
- Strictly follow activity restrictions: Limiting your dog’s movement helps prevent stress on the healing knee and avoids complications.

- Monitor the surgical site daily: Checking for signs of infection or other problems helps catch issues early.
- Provide a safe, comfortable environment: Making home adjustments supports rest and reduces injury risks.
- Attend all follow-up vet visits: These appointments let the vet track progress and make necessary treatment changes.
- Support rehabilitation exercises: Helping your dog with physical therapy improves strength and joint function.
Your commitment to these care steps ensures your dog stays comfortable and recovers well. Missing instructions or allowing too much activity can slow healing or cause setbacks. By staying attentive and proactive, you give your dog the best chance for a full, healthy recovery.
Recovery Variations Based on Surgery Type
Recovery after medial patellar luxation surgery can vary depending on the surgical method used. Different techniques address specific issues with the kneecap and surrounding structures, which affects the healing process and activity restrictions.
Some common surgical methods include deepening the groove where the kneecap sits (trochleoplasty), tightening or loosening tendons and ligaments around the knee, and correcting bone deformities in the thigh or shin bone. Each approach has slightly different recovery needs.
- Trochleoplasty (groove deepening): This method involves reshaping the bone groove, so healing may take longer because bone tissue needs to remodel. Strict rest is essential for 6 to 8 weeks to allow the bone to heal properly.
- Soft tissue procedures (tendon or ligament adjustments): These surgeries often involve less bone healing, so your dog might regain movement slightly faster but still requires controlled activity.
- Corrective osteotomy (bone realignment): This is a more complex procedure where bones are cut and repositioned. Recovery can be longer and may require additional pain management and physical therapy.
Your vet will explain the specific recovery plan based on the surgery type, helping you manage activity levels, pain control, and rehabilitation to ensure the best healing outcome. Understanding these differences prepares you to support your dog properly through recovery.

How do I know if my dog’s surgical wound is healing well?
A healing wound should have minimal swelling, no redness spreading beyond the incision, and no foul-smelling discharge. Some bruising and mild swelling are normal early on. If you notice increased redness, warmth, pus, or your dog excessively licking the area, contact your vet promptly to prevent infection.
What signs mean I should call the vet during recovery?
Call your vet if your dog shows severe limping, refuses to use the leg, has swelling or discharge at the surgery site, or develops fever, lethargy, or loss of appetite. These signs may indicate infection, reluxation, or other complications requiring urgent veterinary care to protect your dog’s recovery.

Signs and Symptoms of Medial Patellar Luxation in Dogs
Learn the common signs and symptoms of medial patellar luxation in dogs to spot early warning signs and get timely veterinary care for your pet
Understanding Medial Patellar Luxation
Medial Patellar Luxation (MPL) is a condition where the kneecap (patella) slips out of its normal position toward the inside of the dog’s leg. This causes the knee joint to become unstable, leading to pain and difficulty walking. MPL is common in small dog breeds but can affect dogs of all sizes.
Recognizing the symptoms of MPL early is very important. When caught early, treatment can reduce pain and prevent long-term damage like arthritis. Early care helps your dog stay active and comfortable. If left untreated, the condition can worsen, causing more severe limping and joint problems.
By watching for signs like limping, skipping steps, or stiffness, you can get your dog the help they need quickly. Early veterinary care improves your dog’s quality of life and can often avoid the need for complex surgery.
Common Movement-Related Signs of MPL
Medial Patellar Luxation (MPL) often changes how your dog moves. Watching for these signs can help you notice the problem early.
- Sudden skipping or hopping while walking or running: Your dog may suddenly lift one leg or hop to avoid pain when the kneecap slips out of place. This quick change in movement helps reduce discomfort.
- Limping or skipping gait: Limping is common when the dog puts less weight on the affected leg. You might see an uneven or skipping walk as your dog tries to avoid putting pressure on the painful knee.
- Intermittent or persistent lameness: Sometimes, lameness happens only after exercise, but in more serious cases, your dog may limp all the time. Both need veterinary attention to avoid worsening.
- Holding the affected leg up or avoiding weight bearing: Your dog might lift the injured leg or refuse to stand on it because of pain or instability in the knee.
If you notice these signs, it’s important to see a vet for diagnosis and early treatment.
Pain and Mechanical Symptoms
Dogs with Medial Patellar Luxation (MPL) often show pain and unusual knee movements. Watching for these signs can help you know when your dog needs care.
- Pain or discomfort around the knee area:
Your dog may lick, bite, or favor the leg because of pain. The discomfort can be mild or severe depending on how often the kneecap slips out of place. - Visible abnormal movement or popping of the kneecap:
You might see the kneecap move out of its groove or the knee looking unstable. This popping happens especially when your dog walks or stands. - Audible clicking or popping sounds from the knee:
Sometimes you can hear clicking noises when the kneecap slips out and back in. This sound shows the knee joint is unstable.
If you notice any of these pain or mechanical symptoms, visit your vet. Early treatment can reduce pain and stop more damage to the knee joint.
Functional Difficulties and Posture Changes
Medial Patellar Luxation (MPL) can cause problems with how your dog moves and stands. These changes affect your dog’s daily activities and comfort.
- Stiffness or difficulty walking after rest:
Your dog may seem stiff or slow to start moving after resting. This happens because the knee feels tight or sore, making it hard to walk smoothly. - Difficulty jumping or climbing stairs:
Activities that put extra pressure on the knees, like jumping or going up stairs, can become hard or painful. Your dog might avoid these tasks to reduce discomfort. - Bow-legged appearance or abnormal hind limb posture:
In some cases, the leg may look bow-legged or positioned oddly due to changes in the knee joint and surrounding muscles. - Knee joint instability or looseness:
The knee may feel loose or unstable because the kneecap is not held securely. This can cause your dog to wobble or struggle with balance.
If you notice these signs, it’s important to get your dog checked by a vet. Managing these difficulties early helps keep your dog active and comfortable for longer.
Muscle and Activity Changes
Medial Patellar Luxation (MPL) often leads to changes in your dog’s muscles and activity levels. Because the affected leg causes pain or discomfort, your dog may use it less than usual.
- Muscle loss in the affected leg from reduced use:
When your dog avoids putting weight on the injured leg, the muscles around that leg can shrink or weaken. This muscle loss makes it harder for the knee to stay stable, which can worsen the condition over time. - Decreased activity or reluctance to exercise:
Dogs with MPL may become less active because movement causes discomfort or pain. They might avoid running, jumping, or playing as much as before. This reduction in activity can affect their overall health and fitness.
It’s important to help your dog stay as active as possible without causing pain. Gentle, controlled exercise and physical therapy can improve muscle strength and support the knee joint. Working with your vet to create a safe exercise plan helps your dog stay healthy and feel better despite MPL. Early management of muscle and activity changes improves your dog’s quality of life.
Progression and Severity of Symptoms
Medial Patellar Luxation (MPL) symptoms can change over time and with your dog’s activity level. Often, symptoms get worse as the condition progresses or if your dog is very active.
- Symptoms worsen with activity or over time:
Increased exercise or movement can cause the kneecap to slip more often, leading to more pain and discomfort. Over time, repeated slipping may damage the knee joint, making symptoms more severe. - Mild cases show subtle or occasional signs:
Dogs with mild MPL might only limp sometimes or skip steps now and then. These signs can be easy to miss but still need attention to prevent worsening. - Moderate to severe cases cause frequent lameness and pain:
In more serious cases, dogs limp often or have trouble walking. Pain can be constant, and the knee may feel unstable or locked. - Both hind legs can be affected, usually one side is worse:
Sometimes MPL affects both knees, but one leg often has more severe symptoms. This imbalance can affect your dog’s posture and movement.
Early vet care helps manage symptoms and slow progression, improving your dog’s comfort and mobility.
When to See a Veterinarian
Knowing when to take your dog to the veterinarian is very important if you suspect Medial Patellar Luxation (MPL). Certain signs need prompt veterinary attention to prevent further damage and pain.
Key signs to watch for include sudden limping that doesn’t improve, your dog refusing to put weight on a leg, visible swelling or heat around the knee, or if the leg locks or feels unstable. If your dog shows signs of strong pain, such as whining, crying, or reluctance to move, you should see a vet right away.
Early diagnosis and treatment are crucial for the best outcome. When MPL is caught early, your vet can recommend treatments to reduce pain, improve mobility, and prevent long-term problems like arthritis. Delaying care can cause the condition to worsen, making treatment more complicated and recovery longer.
Regular veterinary check-ups help monitor your dog’s knee health and catch any early changes. If you notice any signs of MPL, don’t wait—visit your vet to protect your dog’s comfort and quality of life.

Early signs include limping, skipping steps, or sudden hopping while walking. Your dog may hold the leg up or avoid putting weight on it. These subtle changes often appear during activity or after rest.
How can I tell if my dog is in pain from MPL?
Dogs may lick or bite their knee, show reluctance to move, or limp frequently. Signs like whining or stiffness after resting also indicate pain related to the kneecap slipping out.
Can MPL cause permanent damage if untreated?
Yes, untreated MPL can lead to arthritis and joint damage. This causes chronic pain, stiffness, and difficulty moving. Early care can prevent these long-term problems.
Why does my dog’s knee make clicking sounds?
Clicking or popping sounds occur when the kneecap slips out and back into place. This noise is a common mechanical symptom of MPL and shows joint instability.
Does MPL affect both legs or just one?
MPL can affect one or both hind legs. Often, one side is more severe, causing uneven movement and posture changes.
When should I take my dog to the vet for MPL symptoms?
If your dog limps suddenly, refuses to put weight on a leg, or shows signs of pain or swelling, see a vet immediately. Early diagnosis improves treatment success.

What Is Medial Patellar Luxation in Dogs? Explained Clearly
Learn what medial patellar luxation in dogs is, its causes, signs, treatment options, and how early care improves your dog’s health and mobility
Understanding Medial Patellar Luxation
Medial Patellar Luxation (MPL) is a condition where the kneecap, called the patella, slips out of its normal position toward the inside of the leg. Normally, the patella sits in a groove at the end of the thigh bone and moves up and down as the dog walks or runs. This helps the dog’s leg bend and straighten smoothly.
In a healthy dog, the patella stays in place because it is held by strong ligaments and muscles. It acts like a pulley for the muscles that straighten the leg. But in dogs with MPL, the kneecap moves out of the groove, causing pain, limping, or difficulty walking. This condition is common in small dog breeds and can vary from mild to severe depending on how often and how far the kneecap slips out.
Causes and Who Is at Risk
Medial Patellar Luxation (MPL) happens when the kneecap moves out of its normal groove, mainly because of changes in the bones, muscles, or ligaments around the knee. The most common causes include:
- Genetic factors: Many dogs inherit weak or misshaped knee structures from their parents.
- Abnormal bone growth: Sometimes the thigh bone or shin bone grows unevenly, making it hard for the patella to stay in place.
- Muscle weakness or imbalance: Weak muscles can fail to keep the kneecap aligned properly.
- Trauma or injury: Sudden injuries can damage the knee joint, leading to luxation.
Certain dog breeds are more likely to get MPL, especially small and toy breeds. This shows a strong genetic link. Breeds commonly affected include:
- Pomeranians
- Yorkshire Terriers
- Chihuahuas
- Poodles
- French Bulldogs
- Maltese
Large breeds can also get MPL, but it is less common. Early diagnosis is important, especially for at-risk breeds, to manage symptoms and avoid worsening damage. Regular vet check-ups help catch this condition early.

Recognizing the Signs and Symptoms
Knowing the signs of Medial Patellar Luxation (MPL) helps you find the problem early. If your dog has MPL, you might notice changes in their walking or behavior that show discomfort or pain in the knee.
Common signs to watch for include:
- Limping or skipping steps: Your dog may suddenly lift one leg while walking or skip steps because the kneecap slips out of place.
- Difficulty running or jumping: They might avoid activities that put pressure on their knees.
- Stiffness or trouble bending the leg: The knee may feel stiff or locked at times.
- Swelling or tenderness around the knee: You might see or feel swelling where the kneecap should be.
- Holding the leg up: Your dog may hold the affected leg off the ground to avoid pain.
- Repeated clicking or popping sounds: Sometimes you can hear or feel the kneecap moving out and back into place.
If you notice any of these signs, especially in small breeds, take your dog to a vet for a full check. Early treatment helps prevent more damage and improves your dog’s comfort and mobility.
Diagnosing the Condition
When you take your dog to the vet with signs of Medial Patellar Luxation (MPL), the vet performs a careful exam to find the problem. They check the dog’s leg for pain, swelling, and how well the knee moves. The vet will try to feel if the kneecap slips out of its normal groove when the leg bends or straightens.
During the physical exam, the vet looks for:
- Limping or signs of discomfort
- Abnormal leg movement
- The position of the kneecap when moving the leg
- Muscle tone around the knee
To confirm the diagnosis, the vet often uses X-rays. X-rays show the shape of the bones and help find any bone changes or damage in the knee joint. Sometimes, the vet may use special imaging like CT scans for a more detailed view.
These tools help the vet decide the severity of MPL and the best treatment plan. Early and accurate diagnosis is important to prevent long-term damage and improve your dog’s quality of life.

Treatment Options for MPL
Treatment for Medial Patellar Luxation (MPL) depends on how severe the condition is and how much it affects your dog’s movement.
Conservative care may help in mild cases where the kneecap only slips occasionally and your dog shows little pain. This includes:
- Weight management to reduce pressure on the knees
- Gentle exercise to keep muscles strong
- Anti-inflammatory or pain medicines prescribed by the vet
- Physical therapy or rehab exercises
If conservative care does not improve symptoms or if the luxation is moderate to severe, surgery is often needed. Surgery aims to realign the kneecap and stabilize the joint to prevent it from slipping out again.
Common surgical options include:
- Deepening the groove where the kneecap sits
- Tightening or loosening tendons and ligaments around the knee
- Correcting bone deformities in the thigh or shin bone
Surgery usually improves your dog’s mobility and reduces pain. Early surgery can prevent arthritis and long-term joint damage. Your vet will recommend the best treatment based on your dog’s age, breed, and MPL severity.

The Importance of Early Treatment
Leaving Medial Patellar Luxation (MPL) untreated can cause serious problems for your dog over time. When the kneecap keeps slipping out of place, it damages the knee joint. This damage leads to pain, swelling, and inflammation. If untreated, MPL often causes arthritis, which makes the joint stiff and sore. Arthritis is a long-term condition that reduces your dog’s ability to move and enjoy life.
Untreated MPL can also cause your dog to limp more, change how they walk, or even develop problems in other legs due to uneven weight bearing. These changes may cause muscle loss and reduce overall leg strength.
Early treatment helps avoid these risks. When treated early, whether with medicine, physical therapy, or surgery, your dog is less likely to develop arthritis or permanent joint damage. Early care improves comfort, helps your dog stay active, and speeds recovery. Regular vet visits and quick action when you notice signs of MPL give your dog the best chance for a happy, healthy life.
Living with Medial Patellar Luxation
Medial Patellar Luxation (MPL) can affect your dog’s life and how well they move. Dogs with MPL may limp or avoid running and jumping because their knee hurts or feels unstable. If the condition is mild, your dog might still enjoy normal activities with little trouble. But if MPL is more severe, it can cause ongoing pain and make walking hard.
You can help your dog live comfortably by managing symptoms at home. Here are some tips:
- Keep your dog at a healthy weight to reduce pressure on the knees.
- Provide soft bedding to support sore joints.
- Avoid slippery floors where your dog could slip and injure their knee.
- Use gentle, controlled exercise like short walks to keep muscles strong without causing stress.
- Follow your vet’s advice on medicines or supplements for joint health.
- Physical therapy or simple home exercises can improve muscle strength and knee stability.
With proper care and attention, dogs with MPL can still enjoy a good quality of life. Regular vet check-ups help monitor the condition and adjust treatment as needed.
When to See the Vet
Knowing when to take your dog to the vet is important if they have Medial Patellar Luxation (MPL). Some signs need immediate veterinary care to prevent worsening damage or serious pain. Watch for:
- Sudden severe limping or inability to put weight on the leg
- Visible swelling, heat, or redness around the knee
- Your dog showing signs of strong pain like whining or refusing to move
- The leg locking in place or sudden changes in walking
- Signs of injury after a fall or accident
If you see these signs, contact your vet right away for an exam.
Even without emergencies, regular vet visits are important for dogs with MPL. Your vet will check how the condition is progressing and update treatment as needed. They may recommend X-rays or physical therapy to keep the knee healthy.
Routine monitoring helps catch new problems early and improves your dog’s comfort. Stay in touch with your vet and follow their advice to help your dog live well despite MPL. Early care and regular check-ups make a big difference in managing this condition.
