The meniscus is a C-shaped cartilage in a dog's knee (stifle) joint that cushions and stabilizes movement. It absorbs shock and spreads weight evenly across the joint, preventing excessive wear on the bones. Each knee has two menisci—medial (inner) and lateral (outer). The medial meniscus is more prone to injury because it is firmly attached to the tibia.

After TPLO (Tibial Plateau Leveling Osteotomy) surgery, meniscal tears can still happen, even though the procedure stabilizes the knee. This can occur due to ongoing joint instability before surgery, direct trauma, or degenerative changes. In some cases, the meniscus was already damaged before TPLO but went unnoticed.

Meniscal tears often cause pain, limping, and clicking sounds in the knee. Some surgeons perform a meniscal release during TPLO to lower post-op risks, but this may affect joint function. Early detection and treatment are crucial to prevent long-term mobility issues.

Causes of Meniscal Tears After TPLO Surgery

Meniscal tears after TPLO surgery can happen due to several reasons, even though the knee is surgically stabilized. While TPLO aims to prevent further damage, certain conditions can still stress the meniscus, causing injury.

1. Excessive or abnormal force during healing – After TPLO surgery, the knee joint still bears weight. If a dog is too active too soon, too much stress on the meniscus can lead to tearing. Sudden movements, slipping, or jumping before full recovery can put abnormal pressure on the cartilage.
2. Pre-existing meniscal damage – Sometimes, the meniscus is already torn before TPLO but isn't visible during surgery. A partial tear can become a full tear over time, especially if the joint stays irritated or inflamed.
3. Abnormal tibial alignment after surgery – If the tibia isn't properly aligned during TPLO, leftover instability may continue, causing repeated stress on the meniscus. Poor surgical technique or individual anatomical differences can lead to this problem, resulting in ongoing joint damage even after the procedure.

Symptoms of a Meniscal Tear in Dogs

A meniscal tear after TPLO surgery can cause significant discomfort and mobility issues. While some symptoms overlap with general knee problems, certain signs strongly suggest meniscal damage.

1. Limping or lameness – A dog with a torn meniscus often shows a sudden return of limping after initial TPLO recovery. The lameness may come and go, worsening after activity.
2. Difficulty bearing weight on the affected leg – Dogs may hesitate to put full weight on the injured leg, sometimes lifting it when standing still. Some dogs shift weight to the opposite leg, leading to uneven posture.
3. Swelling around the knee joint – Inflammation in the stifle joint can occur, making the area around the knee appear swollen or warm to the touch. This often indicates irritation or internal damage.
4. Pain or sensitivity when the joint is touched – Affected dogs may react when the knee is examined, showing discomfort by pulling away, whining, or licking the joint.
5. Reluctance to engage in physical activity – A previously active dog may become less willing to walk, run, or climb stairs due to pain. If untreated, this can lead to muscle loss and further joint complications.

Diagnosing a Meniscus Tear After TPLO Surgery

Identifying a meniscal tear after TPLO surgery involves a combination of clinical examination and advanced diagnostic tools. Since symptoms can mimic other knee issues, a thorough assessment is essential for an accurate diagnosis.

1. Physical Examination and Manual Manipulation – A veterinarian will evaluate the affected limb by observing gait, joint swelling, and pain response. A key test is the "meniscal click" sign, where a clicking or popping sound is felt when flexing and extending the knee. However, not all tears produce this sign, so further diagnostics may be needed.
2. Arthrotomy or Arthroscopy (Direct Visualization) – If a meniscal tear is highly suspected, direct visualization is the most reliable way to confirm it. Arthrotomy involves surgically opening the joint, while arthroscopy is a minimally invasive technique using a small camera. Arthroscopy allows for greater precision and faster recovery, making it the preferred method in many cases.
3. Advanced Imaging Techniques (MRI, CT Scans) – While X-rays do not show soft tissues, MRI or CT scans can help detect meniscal injuries. MRI provides the best soft tissue detail, though its availability in veterinary medicine is limited. CT scans with contrast can sometimes help but are less effective than MRI for diagnosing meniscal damage.

Treatment Options for a Meniscal Tear

The treatment for a meniscal tear after TPLO surgery depends on how severe the injury is. Mild cases might improve with conservative management, but severe tears often need surgery to restore joint function and relieve pain.

Conservative Management (For Mild Cases)

For minor meniscal injuries, non-surgical treatments can help manage pain and prevent further damage:

• Rest and restricted activity – Strict crate rest or controlled leash walking for several weeks prevents the tear from getting worse.
• Physical therapy and rehabilitation – Gentle exercises, hydrotherapy, and laser therapy improve mobility without putting stress on the joint.
• Pain management (NSAIDs, joint supplements) – Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce swelling, while glucosamine and chondroitin support cartilage health.

This approach works best for small, stable tears and requires close monitoring for any worsening symptoms.

Surgical Treatment (For Severe Cases)

Severe meniscal tears often need surgery to restore function and prevent chronic pain:

• Partial meniscectomy – The damaged part of the meniscus is removed to eliminate pain and mechanical obstruction.
• Meniscal repair – In rare cases, suturing the tear is possible, though outcomes are less predictable.
• Expected recovery timeline after surgery – Most dogs recover within 8–12 weeks, with physical therapy helping to improve mobility and muscle strength.

Postoperative Care and Recovery

Proper postoperative care is crucial for a successful recovery after meniscal tear surgery. A structured rehabilitation plan helps reduce pain, restore mobility, and prevent further joint damage.

1. Controlled Leash Walks and Restricted Movement – Dogs should avoid running, jumping, or rough play for several weeks after surgery. Short, leashed walks on flat surfaces help maintain circulation while preventing too much stress on the knee. Crate rest or a confined space is recommended when unsupervised.
2. Passive Range of Motion Exercises – Once approved by the veterinarian, gentle bending and straightening of the knee help maintain joint flexibility. This should be done slowly and without forcing movement to avoid discomfort.
3. Ice and Heat Therapy for Pain Relief – Applying ice packs (wrapped in a towel) to the knee for 10–15 minutes several times a day reduces swelling in the first few weeks. Later, warm compresses can be used to improve blood flow and relax stiff muscles.
4. Gradual Return to Normal Activity – Around 8–12 weeks after surgery, supervised activity can increase. Hydrotherapy, slow stair climbing, and controlled treadmill walking are beneficial. A full return to normal activity typically takes 3–4 months, depending on healing progress.

Signs to Watch for During Recovery

Monitoring your dog’s recovery after meniscal tear surgery is crucial to ensure proper healing. While some discomfort is expected, certain signs may indicate complications that require veterinary attention.

1. Swelling Lasting Longer Than 5–7 Days – Mild swelling around the knee is normal after surgery, but it should gradually decrease. Persistent or worsening swelling beyond a week may indicate inflammation, infection, or fluid buildup in the joint.
2. Persistent Pain Despite Medication – Pain should decrease over time with prescribed NSAIDs and other pain relief medications. If your dog continues to show signs of discomfort, such as whining, excessively licking the knee, or avoiding movement, it may suggest ongoing joint irritation or surgical complications.
3. Inability to Bear Weight 5–7 Days Post-Surgery – While some dogs may take a few days to regain full weight-bearing ability, complete reluctance to use the affected leg beyond a week could signal continued meniscal issues, improper healing, or implant complications.
4. Any Unusual or Concerning Symptoms – Signs like discharge from the incision, fever, or a sudden increase in limping warrant immediate veterinary attention. Catching these issues early can prevent long-term mobility problems and ensure a smooth recovery.

How to Prevent Meniscal Tears After TPLO

Preventing a meniscal tear after TPLO surgery involves careful post-surgery management and ongoing joint care. While TPLO stabilizes the knee, extra precautions help protect the meniscus and support full recovery.

1. Proper Post-Surgical Rehabilitation – A structured rehab plan is essential to avoid putting too much stress on the knee. Controlled leash walks, passive range-of-motion exercises, and hydrotherapy strengthen the joint without overloading the meniscus. Sudden, unapproved activities can increase the risk of injury.
2. Avoiding High-Impact Activities Too Soon – Running, jumping, or playing too early in recovery can strain the healing knee and harm the meniscus. Gradually reintroducing activity, based on veterinary advice, reduces the risk of re-injury.
3. Regular Vet Checkups to Monitor Healing – Follow-up visits allow the vet to check joint stability, swelling, and pain levels. If instability or discomfort continues, early intervention can prevent further meniscal damage.
4. Supplements or Therapies to Support Joint Health – Glucosamine, chondroitin, and omega-3 fatty acids help maintain cartilage health and reduce inflammation. Physical therapy, including laser treatment or acupuncture, can improve mobility and prevent additional joint issues. Proper joint care ensures long-term knee function and minimizes re-injury risks.

Early detection and treatment of a meniscal tear after TPLO surgery are crucial for preventing long-term joint damage and ensuring a successful recovery. Recognizing symptoms like limping, pain, and difficulty bearing weight allows for timely intervention, reducing the risk of further complications.

A structured rehabilitation plan is essential for recovery. Controlled leash walks, physical therapy, and gradually reintroducing activity help protect the knee joint and prevent additional injuries. Proper post-operative care, including pain management, restricted movement, and joint-supporting supplements, contributes to long-term stability and comfort.

If your dog shows persistent pain, swelling, or reluctance to use the affected leg beyond the expected healing period, consult a veterinarian immediately. Unaddressed meniscal damage can lead to chronic discomfort and reduced mobility. With careful monitoring, rehabilitation, and veterinary guidance, dogs can regain full function and enjoy an active, pain-free life after TPLO surgery.

FAQs

What happens if a dog tears the meniscus after TPLO?

If a dog tears the meniscus after TPLO, it can cause pain, lameness, and joint instability. The knee may produce a clicking sound when moving. If left untreated, it can lead to chronic discomfort and arthritis. Treatment options include pain management, restricted activity, or surgery to remove the damaged meniscus.

Can a torn meniscus in a dog heal on its own?

No, a torn meniscus does not heal on its own because it has limited blood supply, preventing natural regeneration. Small tears may be managed with rest, NSAIDs, and joint supplements, but severe cases often require surgical intervention, such as a partial meniscectomy, to remove the damaged portion and restore knee function.

How to know if a dog ruined TPLO surgery?

Signs of a failed TPLO surgery include persistent limping, swelling, reluctance to bear weight, and worsening pain beyond the expected recovery period. A sudden decline in mobility or unusual clicking sounds may indicate complications like implant failure, infection, or a meniscal tear. A veterinary exam, X-rays, or arthroscopy can confirm the issue.

How to fix a meniscus tear in dogs?

Treatment depends on severity. Mild tears may be managed with pain relief, restricted activity, and joint therapy. Severe tears often require surgery, such as a partial meniscectomy, where the damaged meniscal portion is removed. In rare cases, meniscal repair may be attempted, though its success rate is lower than removal.

Why is my dog limping 4 months after TPLO?

Limping four months post-TPLO could indicate a meniscal tear, incomplete healing, implant issues, or arthritis. While mild stiffness is normal, worsening lameness, pain, or joint clicking requires veterinary evaluation. X-rays or arthroscopy can help identify complications, and treatment may involve physical therapy, pain management, or additional surgery if needed.

‍

TPLO (Tibial Plateau Leveling Osteotomy) is a special surgery used to treat cranial cruciate ligament (CCL) injuries in dogs. By adjusting the tibial plateau angle, TPLO stabilizes the knee joint, allowing for better weight distribution, reducing pain, and improving mobility. It is considered one of the most effective treatments for CCL tears, especially in large or active dogs.

The cost of TPLO surgery can vary widely, usually ranging from $3,500 to $7,000 (or even more). Several factors affect the price, including:

• the location of the veterinary clinic
• the surgeon's expertise
• preoperative diagnostics
• hospitalization
• anesthesia
• post-surgical care

Additional costs may include medications, follow-up visits, rehabilitation, and potential complications.

Specialist hospitals and board-certified surgeons often charge more due to their advanced training and high success rates. Additionally, regional differences in veterinary care costs can affect pricing, making TPLO surgery more expensive in urban areas than in smaller towns.

Factors That Influence TPLO Surgery Costs

Dog’s Size and Weight

Larger dogs need stronger, more durable implants, which raises material costs. They also require higher doses of anesthesia, longer surgeries, and more monitoring during recovery. The complexity of handling a large dog's knee joint makes the surgery more technically challenging, leading to higher fees.

Smaller dogs, while still needing precise surgery, usually have lower implant costs and reduced medication expenses. Veterinary clinics adjust their pricing based on the dog's weight, as it directly impacts the surgery's difficulty, recovery time, and post-operative care, causing variations in overall TPLO surgery costs.

Geographic Location

TPLO surgery costs can vary greatly depending on the clinic's location. In urban areas, prices are usually higher because of increased overhead costs, like facility expenses, staff salaries, and the demand for specialized services. Rural clinics might offer lower prices, but they may not have access to board-certified surgeons or advanced surgical equipment.

Costs also vary between states and countries, affected by regional economic conditions, veterinary licensing fees, and medical supply costs. Pet owners in areas with a high cost of living should expect to pay more, while those in smaller towns might find more affordable options.

Veterinary Clinic’s Pricing Strategy

The type of veterinary clinic also affects TPLO surgery costs. Corporate-owned clinics often have set prices, which may be higher due to overhead and administrative expenses. Private practices might offer more flexible pricing but can also charge higher rates if they have a strong reputation.

Clinics with high demand, advanced equipment, and top-notch facilities usually charge more. Some hospitals include follow-up care in their pricing, while others list these costs separately, impacting the total amount pet owners need to pay. Choosing between different clinic types can significantly influence the final surgery bill.

Severity of the Injury

The extent of ligament damage directly impacts TPLO surgery costs. A partial tear might need less surgical work and result in lower costs, while a complete rupture usually requires more complex reconstruction.

Additional issues like meniscus tears, osteoarthritis, or joint inflammation make the surgery more difficult and increase post-operative care, raising overall expenses.

In severe cases, longer hospital stays, extra imaging, and specialized rehabilitation may be necessary, further increasing costs. Veterinary surgeons evaluate each dog's condition individually, deciding on the level of intervention needed and adjusting the treatment plan as necessary.

Necessary Implants and Materials Used

The type and quality of implants, plates, and screws used in TPLO surgery can greatly affect costs. High-grade titanium or stainless steel implants are more expensive but offer better durability and a lower risk of complications. Customized implants, made for larger or more active dogs, also increase costs due to their specialized design.

Some clinics might use generic implants to keep costs down, while others choose premium, brand-name materials for better long-term results. The choice of implants impacts not only the price but also post-surgery stability, healing time, and overall success rates.

Surgeon’s Expertise and Qualifications

Board-certified veterinary surgeons usually charge more than general veterinarians because of their specialized training and higher success rates. These experts have a lot of experience in orthopedic procedures, which leads to better surgical results.

While general veterinarians can perform TPLO surgery at a lower cost, they might not have the same level of expertise, which could affect recovery and complication rates.

Some pet owners choose experienced surgeons despite the higher cost, focusing on safety, precision, and long-term joint health for their dogs. Selecting a skilled surgeon often results in faster recovery and fewer post-surgical problems.

Regional Cost Comparison

The cost of TPLO surgery varies significantly by country and location due to differences in veterinary fees, cost of living, and availability of specialized surgeons. Below is a general comparison of TPLO surgery costs in different regions:

‍

‍

Urban clinics usually charge more because of higher operating costs and greater demand for specialist services. In contrast, rural clinics often have lower prices but may not have board-certified surgeons.

Additionally, pet insurance can greatly affect out-of-pocket costs, as some policies cover part or all of the TPLO surgery expenses, depending on the region and the plan.

Cost Variations by Dog Size

The cost of TPLO surgery varies based on the size of the dog, mainly because of differences in implant needs, anesthesia dosage, and surgical complexity. Here's a breakdown of approximate costs by weight category:

• Small Dogs (<40 lbs) – Approximately $4,450
  Smaller dogs need smaller implants and less anesthesia, making their surgery a bit less complex. However, the cost is similar to larger dogs because specialized skills and equipment are still necessary.
• Medium Dogs (40–70 lbs) – Approximately $4,450
  Dogs in this weight range usually need standard-sized TPLO plates, keeping costs similar to small dogs. The surgical method and recovery care are also similar.
• Large Dogs (70–100 lbs) – Varies Based on Plate Size
  Costs increase for larger dogs due to the need for stronger, larger TPLO plates. Some clinics charge extra for custom implants that offer better durability and long-term joint support.
• Extra-Large Dogs (>100 lbs) – $4,450 to $5,950
  Giant breeds require reinforced implants, more anesthesia, and longer surgery time, which raises the overall cost. Post-surgical care and rehabilitation may also be more intensive, further affecting expenses.

Larger dogs often have higher long-term care costs, including pain management and physical therapy, making post-operative planning crucial for their recovery.

What’s Included in the TPLO Surgery Cost?

The total cost of TPLO surgery usually includes several components to ensure a safe procedure, proper recovery, and post-operative care. Here is a breakdown of what is typically included:

• Pre-Surgical Bloodwork: Before surgery, veterinarians perform blood tests to check the dog’s overall health, making sure they can safely handle anesthesia and recover without issues.

• X-Rays for Diagnosis and Surgical Planning: Preoperative X-rays are needed to confirm the severity of the CCL tear and determine the exact tibial angle for surgical correction. Post-surgical X-rays may also be taken to ensure the implant is properly placed.
• Anesthesia and Surgical Monitoring: TPLO surgery requires general anesthesia, which is carefully given and monitored throughout the procedure. The cost includes oxygen support, IV fluids, and continuous tracking of vital signs to ensure the dog's safety.
• Actual TPLO Surgical Procedure: This includes the orthopedic surgery itself, where the surgeon makes a precise bone cut, repositions the tibial plateau, and secures it with plates and screws.
• Post-Operative Pain Medications: Pain management is crucial for recovery. The cost typically includes anti-inflammatory drugs, antibiotics, and pain relievers to prevent infection and discomfort.
• Follow-Up Visits and Check-Ups: Most clinics include at least one or two post-surgery appointments to monitor healing and assess the dog's progress. Additional visits may be needed if there are complications.
• Physical Therapy or Rehabilitation Sessions (If Included): Some veterinary clinics offer rehabilitation programs like hydrotherapy or therapeutic exercises to help improve recovery. However, not all clinics include these services in the base surgery cost.

Each clinic has its own pricing structure, so it's important to check what is included to avoid unexpected costs during recovery.

Hidden or Unexpected Costs of TPLO Surgery

While TPLO surgery is highly effective, some additional expenses may arise depending on the dog's recovery process and the clinic’s pricing structure.

• Emergency Care for Complications: Although rare, complications such as implant loosening, poor bone healing, or excessive swelling may require extra treatment. Even with lower infection risks using Simini Protect Lavage, issues like implant irritation or allergic reactions might still occur, needing additional veterinary care.
• Additional Pain Management Medications: While most TPLO surgery packages include standard pain medications, some dogs might need stronger or longer-term pain relief, especially if they have pre-existing joint issues or heal slowly.
• Post-Surgery X-Rays for Recovery Monitoring: Some veterinary clinics charge separately for follow-up X-rays at 6-8 weeks post-surgery to confirm proper bone healing. If not included, these can cost $150 to $300 per session.
• Rehabilitation and Therapy (If Not Included in Base Cost): Hydrotherapy, laser therapy, or guided rehabilitation exercises can enhance recovery but may add $50 to $100 per session.

With advanced infection control measures like Simini Protect Lavage, unexpected costs related to post-operative infections are minimized, making TPLO recovery more predictable and reducing financial uncertainties.

Payment and Financing Options for TPLO Surgery

TPLO surgery is a significant financial commitment, but various payment and financing options can help manage the cost. Pet owners should explore different ways to reduce financial strain while ensuring their dog gets the necessary treatment.

• Flexible Payment Plans Offered by Some Clinics: Many veterinary clinics offer in-house payment plans, allowing owners to pay in installments instead of a lump sum. These plans typically require a deposit upfront, with the remaining balance spread over several months.
• Discounts for Upfront Payments: Some clinics provide discounts for paying in full before the surgery. This option can help save money, as interest fees from financing plans are avoided. It's worth asking if a prepayment discount is available.
• Third-Party Financing or Personal Loans: Veterinary financing companies like CareCredit and Scratchpay offer low-interest or interest-free short-term loans for pet medical expenses. Personal loans or credit cards can also be an option, but they may come with higher interest rates.
• Pet Insurance Coverage Considerations: Not all pet insurance plans cover TPLO surgery. Policies that include orthopedic conditions or CCL injuries may reimburse a portion of the cost. Companies like Trupanion, Healthy Paws, and Embrace often cover TPLO surgery, but pre-existing conditions are typically excluded. Pet owners should check waiting periods and coverage limits before proceeding.

Discussing these options with the veterinary clinic can help find the best financial solution for your dog’s surgery.

Additional Considerations Before Committing to TPLO

Before proceeding with TPLO surgery, it’s important to consider potential risks, unexpected costs, and pricing differences between clinics to ensure you are fully prepared for the financial and medical aspects of the procedure.

Risks of Unexpected Complications and Added Cost

While TPLO surgery has a high success rate, complications such as implant failure, delayed bone healing, or improper post-operative care can lead to additional expenses. Some dogs may require extended rehabilitation, extra pain management, or revision surgery, increasing costs beyond the initial estimate.

While infection risks are lower when using Simini Protect Lavage, other factors like poor post-op care or underlying health conditions may still affect recovery.

Comparing Quotes from Different Veterinary Clinics

Prices for TPLO surgery can vary significantly between clinics based on location, surgeon expertise, and included services. It’s recommended to get multiple quotes, ensuring you compare what’s included, such as pre-op tests, X-rays, follow-up visits, and rehabilitation.

Taking the time to understand potential costs and evaluate different providers can help ensure the best possible care for your dog while managing expenses effectively.

Is TPLO Worth the Cost? Long-Term Financial Benefits

While TPLO surgery is expensive, it is often a cost-effective investment in a dog’s long-term health. Choosing not to proceed with TPLO can lead to chronic pain, progressive arthritis, and long-term medical expenses that may exceed the cost of surgery.

Cost of Not Doing TPLO

Without surgical intervention, a torn cranial cruciate ligament (CCL) leads to joint instability, inflammation, and arthritis progression. Managing these issues requires lifelong pain medications, anti-inflammatory drugs, physical therapy, and joint supplements—costs that add up over time. Many dogs that do not undergo TPLO eventually experience injury in the opposite knee, further increasing medical expenses.

TPLO as an Investment in Mobility and Health

TPLO surgery restores knee stability, reduces pain, and allows for full weight-bearing movement, enabling dogs to return to normal activity levels. Unlike conservative management, TPLO prevents further joint deterioration, reducing the need for ongoing medical intervention.

How TPLO Saves Money in the Long Run

While conservative treatments like bracing, pain management, and therapy may seem cheaper initially, they often require years of continuous care.

TPLO, on the other hand, is a one-time surgical cost that provides a permanent solution, minimizing future expenses and improving a dog’s quality of life.

‍

A year after TPLO surgery, most dogs regain full mobility. However, if your dog is still limping, it means something is wrong. Some stiffness or mild discomfort might happen after intense activity, but ongoing limping is not normal during recovery.

TPLO (Tibial Plateau Leveling Osteotomy) is a very effective procedure for cranial cruciate ligament (CCL) injuries. It stabilizes the knee and restores function. Most dogs fully recover within six months, though there can be minor differences. If limping continues beyond a year, it might be due to issues like implant problems, arthritis, or muscle atrophy.

While this can be worrying, the good news is that most causes can be diagnosed and treated. Finding out why your dog is limping is the first step to helping them regain comfort and mobility. Let’s look at potential causes and the best solutions.

Common Causes of Limping 1 Year After TPLO Surgery

If your dog is still limping a year after TPLO surgery, there could be several underlying reasons. Here are the most common causes, their symptoms, and how to address them.

1. Arthritis Development in the Affected Joint

Arthritis is a common long-term issue after TPLO surgery due to changes in joint mechanics and natural wear over time. Although TPLO stabilizes the knee, it cannot completely prevent degenerative joint disease (DJD). Inflammation from surgery, altered weight distribution, and existing cartilage damage can lead to arthritis after surgery.

Dogs with arthritis often show stiffness, especially after resting or waking up. They may be reluctant to run, jump, or climb stairs, and their discomfort often worsens in cold or damp weather.

To manage arthritis, veterinarians usually prescribe

• NSAIDs (e.g., carprofen or meloxicam) to reduce inflammation and pain.
• Joint supplements, like glucosamine, chondroitin, and omega-3 fatty acids, can help slow cartilage degeneration.
• Controlled exercise, such as short walks and swimming, strengthens muscles while reducing joint strain.

2. Implant Failure or Loosening

TPLO implants, including plates and screws, are meant to provide lifelong stability, but sometimes they can loosen over time. Too much activity during recovery, improper bone healing, or an unnoticed infection can weaken the implant's hold, causing joint instability and discomfort.

Signs of implant failure include persistent swelling, worsening lameness, and clicking sounds from the knee when the dog moves.

A veterinarian will confirm the diagnosis using X-rays, which can show shifting hardware or bone resorption around the implant. If instability is found, revision surgery may be needed to replace or remove the implant. In mild cases, managing pain and limiting activity might be enough.

3. Meniscal Tears Occurring After Surgery

The meniscus is an important cartilage in the knee that absorbs shock and helps stabilize movement. After TPLO surgery, the meniscus can still tear, especially if there was existing damage or too much stress on the joint during recovery.

Dogs with a meniscal tear often show:

• sudden limping
• reluctance to put weight on the leg
• a distinct clicking sound when walking

A veterinarian will diagnose the condition through joint palpation and confirm it using MRI or arthroscopy.

Treatment depends on the severity. For significant tears, surgical trimming (partial meniscectomy) is the preferred option, while mild cases may be managed with pain relief and restricted activity.

4. Infection at the Surgical Site or Within the Joint

Though rare, infections can develop months after TPLO surgery due to lingering bacteria or implant-related issues. Dogs with an infection may show:

• Swelling around the surgical site
• Increased warmth in the affected area
• Discharge from the incision
• Lethargy or decreased activity
• Fever and overall discomfort

To confirm an infection, vets perform blood tests and a joint fluid culture to identify the bacteria causing it. Treatment usually involves long-term antibiotics, but in severe cases where the implant is affected, surgical removal of the plate and screws may be needed.

To minimize the risk of infection, many surgeons use Simini Protect Lavage during surgery. This non-antibiotic solution helps reduce biofilm formation and bacterial contamination, lowering the likelihood of post-operative infections. Early intervention remains crucial to prevent further joint damage and ensure a smooth recovery.

5. Compensatory Issues Due to Overuse of Other Limbs

After TPLO surgery, dogs often shift their weight to the opposite leg, which can lead to strain and eventually cause lameness in that limb. This overcompensation may result in secondary joint problems, muscle imbalances, and even early arthritis.

Signs include:

• New limping in the opposite leg
• An unusual gait or stiffness after activity

Treatment focuses on physical therapy to strengthen both hind legs evenly, pain management, and adjusting exercise routines to avoid excessive strain.

Using weight distribution tools, like balance exercises and underwater treadmill therapy, can help correct movement imbalances.

6. Swelling and Inflammation Around the Surgical Area

Persistent swelling near the TPLO site may indicate chronic inflammation due to improper healing, excessive scar tissue, or low-grade irritation around the implant.

Symptoms include:

• visible swelling,
• warmth around the joint, and
• discomfort when touched.

To reduce inflammation, cold therapy (ice packs), laser therapy, NSAIDs (carprofen, meloxicam), and gentle massage therapy are effective. If inflammation continues despite treatment, a vet may check for underlying issues like implant irritation or soft tissue damage.

7. Degenerative Joint Disease Progression

Post-surgical joint degeneration (DJD) can occur if cartilage keeps wearing down after TPLO surgery. Unlike normal aging, DJD leads to a gradual loss of mobility due to ongoing joint damage.

Dogs with DJD show signs like slowly developing limping, joint stiffness, and trouble standing up after resting. Managing DJD involves a long-term joint care plan, which includes weight control, joint supplements (glucosamine, MSM, omega-3s), and prescribed pain medications. Alternative therapies such as acupuncture or hydrotherapy may also help improve mobility.

8. Muscle Weakness or Atrophy Due to Limited Activity

If rehabilitation after TPLO surgery was insufficient, muscle loss (atrophy) can occur, causing the affected leg to look thinner and weaker. This imbalance leads to fatigue, poor joint support, and ongoing limping.

Signs include:

• early exhaustion during walks
• uneven muscle mass
• hesitation to fully use the operated leg

The best treatments include hydrotherapy (such as swimming or using an underwater treadmill), strength training exercises, and controlled walks. Gradual rehabilitation helps rebuild lost muscle, ensuring better joint stability and reducing limping in the long term. These should be recommended by your vet.

Recommended Actions & Treatments to Fix Limping

Identifying the root cause of limping is the first step toward effective treatment and long-term mobility improvement. Here are a few possible treatments to address limping:

1. Consultation with a Veterinarian for Proper Diagnosis

Before assuming the cause of limping, it's important to consult a veterinarian. Many post-TPLO complications have similar symptoms, so a thorough examination is needed to ensure the right treatment.

Vets use X-rays to check for implant loosening or arthritis, and joint fluid analysis to detect infections. If a meniscal tear is suspected, an MRI or arthroscopy can provide a clear diagnosis.

For ongoing or severe cases, an orthopedic specialist might be needed, especially if revision surgery is being considered. Early diagnosis helps prevent further joint damage and ensures the best recovery plan.

2. Implementation of Physical Therapy or Rehabilitation Exercises

Physical therapy is crucial for regaining strength and mobility after TPLO surgery. Hydrotherapy, such as swimming or using an underwater treadmill, is a great low-impact exercise that builds muscle while reducing joint stress. Walking on a treadmill under controlled conditions strengthens the leg without too much strain.

Passive stretching helps maintain flexibility and prevents stiffness, especially in older dogs. A veterinary rehabilitation therapist can create a customized program based on the dog's mobility level. Regular, structured movement supports long-term recovery and lowers the risk of compensatory injuries.

3. Use of Medications Such as Anti-Inflammatories or Pain Relievers

Medication is often needed to manage pain and inflammation, especially if arthritis or joint degeneration occurs. NSAIDs like Carprofen and Meloxicam are commonly prescribed to reduce inflammation. If nerve pain is present, Gabapentin or Tramadol might be recommended.

For dogs with ongoing arthritis, Cartrophen injections (Pentosan Polysulfate Sodium) can help slow the disease and improve joint function. Always discuss long-term medication plans with a vet to minimize potential side effects.

4. Weight Management to Reduce Joint Strain

Excess weight puts extra stress on joints, making limping worse and slowing recovery. Keeping an ideal body weight is essential for dogs after TPLO surgery. If weight loss is needed, a low-calorie prescription diet like Royal Canin Satiety or Hill’s Metabolic can be beneficial.

Controlling portions, measuring food intake, and limiting high-calorie treats help prevent unnecessary weight gain. A low-impact exercise plan, including short, controlled walks and swimming, helps maintain muscle without straining the joints. Regular weight checks during vet visits help track progress.

5. Consideration of Joint Supplements Like Glucosamine and Chondroitin

Joint supplements support long-term mobility and help reduce inflammation in dogs after TPLO surgery. Glucosamine and Chondroitin assist in repairing cartilage, while MSM (Methylsulfonylmethane) has anti-inflammatory properties.

Omega-3 fatty acids (fish oil) help lubricate joints and reduce stiffness, and Green-lipped mussel extract offers natural anti-inflammatory benefits. These supplements are not quick fixes but provide long-term support when used with medication and therapy.

Veterinary guidance ensures the right dosage and effectiveness.

6. Regular Veterinary Check-Ups to Monitor Progress

Routine veterinary check-ups help monitor recovery and catch early signs of complications like arthritis, muscle loss, or implant issues. Regular assessments allow for adjustments to pain management, physical therapy, and diet plans.

During each visit, owners should discuss changes in mobility, pain levels, and any new symptoms with the vet.

When to Consider Additional Surgery or Alternative Treatments

In some cases, additional surgery may be needed if the initial TPLO procedure didn't fully solve the problem. Implant failure (loose plates or screws), severe arthritis, or a meniscal tear that wasn't addressed can cause ongoing pain and instability, requiring revision surgery.

Before considering another operation, alternative therapies can help manage pain and improve joint function:

• Stem cell therapy promotes tissue repair and reduces inflammation.
• PRP (Platelet-Rich Plasma) injections enhance healing and support cartilage health.
• Acupuncture is another option that helps with pain relief and improves circulation.

These treatments can be effective in delaying or even avoiding surgery. A consultation with a vet or specialist can help determine the best approach based on your dog's condition.

Limping a year after TPLO surgery isn't normal, but the good news is it's treatable. As we discussed, the cause could be arthritis, implant issues, muscle weakness, or even a meniscal tear. The sooner you identify the problem, the better your dog's chances of returning to normal.

There are many ways to help, from physical therapy and medications to alternative treatments like PRP injections or acupuncture. But the best first step? A vet visit. They can identify the issue and recommend the right treatment plan.

With proper care, most dogs recover well and stay active for years. So don't wait—your dog's comfort and mobility are worth it.

FAQs

Is it normal for a dog to still limp a year after TPLO surgery?

No, it's not normal for a dog to keep limping a year after TPLO surgery. While minor stiffness can happen, ongoing limping usually points to issues like arthritis, implant problems, or muscle weakness. A vet check-up is recommended to find the cause and decide on the right treatment. Early action can prevent more joint damage and improve long-term mobility.

How do I know if my dog’s TPLO implant is failing?

Signs of implant failure include worsening limping, swelling around the surgery area, and clicking or grinding noises when moving. Sometimes, dogs may feel discomfort when the area is touched. A vet can check implant stability with X-rays. If the implant has shifted or loosened, revision surgery might be needed to restore joint function and relieve pain.

Can physical therapy still help if my dog is limping a year later?

Yes, physical therapy can still help even a year after TPLO surgery. Strengthening exercises, hydrotherapy, and controlled treadmill walking can improve muscle function and joint support. A rehab specialist can create a custom plan based on the cause of the limping. Regular therapy can reduce discomfort, improve mobility, and prevent other injuries.

Are there long-term risks if I don’t address the limping?

Yes, ignoring ongoing limping can lead to worsening arthritis, muscle loss, and more stress on other joints. Dogs might start putting too much weight on the opposite leg, which increases the risk of more injuries. Untreated joint instability can also cause chronic pain and reduced mobility over time. Seeking veterinary advice early can help prevent complications and improve your dog’s long-term quality of life.

What home remedies can I try before going to the vet?

While seeing a vet is best, you can try cold therapy (ice packs) for swelling, gentle massage to ease stiffness, and controlled exercise like short walks. Joint supplements with glucosamine and omega-3s may support joint health. Keeping your dog at a healthy weight also reduces joint strain. However, if the limping continues or gets worse, a vet visit is necessary for proper diagnosis and treatment.

‍

A torn cranial cruciate ligament (CCL) can make a dog limp, feel pain, and have trouble moving. TPLO (Tibial Plateau Leveling Osteotomy) surgery is one of the best and most reliable ways to restore mobility and reduce long-term joint damage. It is highly effective for stabilizing the knee, especially in active or large-breed dogs.

Many pet owners worry: Will my dog walk normally again? How long does recovery take? What improvements can I expect? The good news is that most dogs regain full function within months, often returning to their favorite activities without pain.

However, TPLO is a major surgery that requires careful pre-op planning and dedicated post-op care. This guide will walk you through everything you need to know before, during, and after surgery, based on real insights from veterinary surgeons, helping you make informed decisions for your dog’s health.

Dog's Condition Before and After TPLO Surgery

Knowing what to expect before and after surgery helps you provide the best care and set realistic expectations. Here’s a simple overview of the process.

Before Surgery

Before surgery, your dog probably limps or avoids putting weight on the injured leg. You might see swelling around the knee, difficulty getting up or lying down, and a general reluctance to move. Over time, the affected leg loses muscle, making it even harder to move. If left untreated, the instability in the joint can lead to arthritis, worsening the pain.

Immediately After Surgery

Right after TPLO surgery, your dog will be groggy from anesthesia and need rest. The operated leg will be swollen and stiff, and movement will be very limited. Pain medication and anti-inflammatories will help manage discomfort, but your dog will need assistance with bathroom breaks and must be kept in a confined, quiet space to prevent injury.

2 Weeks Post-Surgery

By the second week, your dog may begin to carefully put some weight on the operated leg. The incision should be healed, but there might still be some swelling. Short, controlled leash walks aid recovery, but running, jumping, or playing is still not allowed. Keeping your dog calm during this time is crucial for proper healing.

6-8 Weeks Post-Surgery

This is when you'll see significant progress. Your dog's strength and stability improve, and they can walk more comfortably. A follow-up X-ray will confirm if the bone is healing correctly. Rehab exercises and controlled movement help rebuild muscle, but unrestricted activity is still not permitted.

3-6 Months Post-Surgery

By this stage, most dogs regain full function. They can run, play, and return to their normal activities without pain. Continued strengthening exercises and weight management are essential to prevent future injuries. If both knees needed surgery, recovery might take a bit longer, but the long-term outcome is excellent.

Now that you have a basic understanding of your dog's condition before and after TPLO surgery, let's explore the details further.

Pre-Surgical Condition of the Dog

Before undergoing TPLO surgery, dogs with a torn CCL face serious mobility issues and discomfort, which get worse over time without treatment.

Limping or Avoiding Putting Weight on the Leg

One of the first and most noticeable signs of a CCL tear is limping. Dogs may initially show mild lameness that worsens with activity and improves with rest. As the ligament damage progresses, they often avoid putting weight on the affected leg entirely.

Instead, they may "toe-touch" or hold the leg off the ground to reduce pain. This altered gait puts extra strain on the healthy leg, increasing the risk of further injury.

Difficulty Standing Up or Lying Down

Dogs with a torn CCL struggle with basic movements like standing up from a resting position or lying down comfortably. They may take longer to rise, hesitate before sitting, or shift their weight awkwardly to avoid pain. Some dogs may resist exercise, preferring to stay in one spot rather than move around. Over time, reluctance to move can lead to stiffness and worsening joint pain.

Progressive Muscle Loss in the Affected Leg

When a dog avoids using the injured leg, the muscles begin to weaken and shrink due to inactivity. This muscle atrophy becomes more visible over time, making the affected leg appear thinner compared to the healthy leg. The loss of muscle mass further reduces knee stability, making movement more painful and recovery more challenging if left untreated.

Signs of Chronic Pain and Discomfort

Chronic pain affects not only a dog's mobility but also its overall behavior. Some dogs become restless and may frequently lick or chew at the knee due to discomfort. Others might become withdrawn, less playful, or even irritable.

Changes in appetite and sleep patterns can also signal ongoing pain. Without treatment, chronic discomfort can lead to arthritis, greatly reducing a dog's quality of life.

What to Expect Immediately After Surgery?

The first few days after TPLO surgery are crucial for recovery. Understanding what's normal and what's not can help you manage your dog's healing process effectively.

First 24 Hours Post-Surgery

After surgery, your dog will be groggy from the anesthesia and may seem disoriented. It's normal for them to be drowsy, sleep more than usual, and have a reduced appetite. The operated leg will probably be swollen and bruised, but this should get better over the next few days.

Managing pain is very important. Vets usually prescribe anti-inflammatory medications (like carprofen or meloxicam) and pain relievers (such as tramadol or gabapentin) to help reduce discomfort and swelling. Some dogs may also receive antibiotics to prevent infection.

First Week: What to Expect

• Strict Crate Rest: Your dog should remain in a confined, safe area, like a crate or small room, to prevent unnecessary movement. Sudden movements can interfere with healing and cause complications. Provide comfortable bedding and keep the area quiet. If your dog is restless, calming aids might be helpful.
• Limited Leash Walks: During the first week, keep leash walks short and slow, only for bathroom breaks. Avoid stairs, slippery floors, and rough terrain. Use a sling or towel under the belly if needed. Running, jumping, and playing are not allowed to prevent re-injury.

Incision Care: Keeping the Wound Clean, Preventing Licking

Proper incision care is essential to prevent infection. Check the wound daily for any redness, swelling, or discharge. The stitches or staples should stay intact, and there should be no excessive bleeding. Avoid bathing your dog or letting the wound get wet until the vet approves.

To prevent licking or chewing, which can lead to infection, your dog must wear an Elizabethan collar (E-collar) or another protective device. If your dog is still too interested in the wound despite the collar, talk to your vet about other protective options, like bandaging or surgical recovery suits.

When to Call the Vet

Contact your veterinarian if you notice:

• Excessive Swelling: Mild swelling is normal, but if the leg appears significantly larger, it might indicate a problem.
• No Weight-Bearing at All: Many dogs avoid using the leg at first, but by 10-14 days, they should begin toe-touching or putting some weight on it.
• Signs of Infection: Redness, warmth, oozing, or a bad smell around the incision may suggest an infection and need immediate attention.

Recovery Timeline & Milestones (Week-by-Week)

Recovery from TPLO surgery happens in stages, and patience is key. Each phase builds on the previous one, ensuring your dog regains full mobility safely.

Weeks 1-2: Strict Rest (Foundation Phase)

The first two weeks focus on rest and healing. Your dog should stay in a confined space, like a crate or small room, to prevent sudden movements that might disrupt healing. Short, controlled leash walks are only for bathroom breaks, and all other activities should be avoided.

Some dogs may start to touch their toes with the operated leg, but full weight-bearing is unlikely at this stage. If your vet advises, passive range-of-motion exercises can help prevent stiffness. It's also important to check the incision site daily for redness, swelling, or discharge that could indicate an infection.

Weeks 3-4: Gradual Activity Increase

By the third week, your dog may begin to put slight weight on the operated leg, but movement should still be limited. Leash walks can be slightly longer, but they must remain slow and controlled.

Running, jumping, and rough play are still not allowed. Ice packs can be used to reduce swelling after activity, and mild rehab exercises may start under veterinary supervision. If your dog shows discomfort or if swelling worsens, reduce activity.

Weeks 5-6: Building Strength

At this stage, your dog's mobility should be improving, and controlled leash walks can be increased to 10-15 minutes. Some dogs benefit from low-impact rehab exercises like balance training or hydrotherapy to help rebuild muscle strength.

Weight-bearing should be more consistent, though it may still be uneven. Any signs of limping, reluctance to walk, or pain should be reported to your veterinarian. Jumping, running, and sudden movements must still be avoided to prevent setbacks.

Weeks 7-8: Regaining Mobility

Most dogs will show significant progress by this point. They should be bearing weight on the leg with minimal difficulty and walking more confidently. Depending on your vet’s recommendation, off-leash movement in a controlled environment may be introduced, but high-impact activities should still be limited.

A follow-up X-ray is usually taken around this time to confirm proper bone healing. If everything looks good, activity levels can be increased gradually under supervision.

3-6 Months: Full Recovery

By the three-month mark, most dogs can return to normal activities, including running and playing. Strength and muscle mass should be fully restored, though ongoing low-impact exercises like swimming or controlled play can help maintain joint health.

Some dogs may still show mild stiffness after long periods of rest, but this usually improves over time. If any lingering discomfort or difficulty is noticed, a veterinary follow-up may be needed.

Following the recovery plan provided by your vet ensures your dog heals safely and returns to a happy, active life without complications. Patience, consistency, and careful monitoring throughout the process will give your dog the best possible outcome.

Common Setbacks & Complications

While most dogs recover well from TPLO surgery, setbacks can occur. Understanding potential complications and knowing when to seek veterinary help can prevent long-term issues and ensure a smooth recovery.

Dog Still Limping After 4 Weeks – Normal or Not?

Mild limping four weeks after surgery is normal since your dog is still recovering. Many dogs continue to favor the operated leg, especially after resting or extended activity. However, if the limp gets worse, stays severe, or your dog refuses to put weight on the leg at all, it might indicate delayed healing, pain, or implant issues. Signs to watch for include:

• Increased swelling or tenderness around the knee
• Yelping or whining when putting weight on the leg
• Sudden reluctance to walk after showing previous improvement

If any of these symptoms appear, a veterinary check-up is necessary to rule out complications like implant irritation, improper healing, or infection.

Infection Risks and How to Spot Them

Post-surgical infections can occur at the incision site or internally. Infections are more likely if a dog licks the wound too much, is in an unclean environment, or has a weak immune system. Look out for these warning signs:

• Redness, swelling, or warmth around the incision
• Discharge (clear fluid is normal, but pus or blood is concerning)
• Foul odor from the wound
• Lethargy, fever, or decreased appetite

As we discussed earlier, to prevent infection, keep the incision clean and dry, ensure your dog wears an E-collar, and follow all prescribed medication instructions. If an infection occurs, your vet may prescribe antibiotics or additional wound care measures. In severe cases, surgery might be needed to clean the area.

Implant Issues – When Does a Plate Need to Be Removed?

The TPLO surgery involves placing a metal plate and screws to stabilize the knee. While most dogs handle this well, some complications can occur, including:

• Implant irritation – Some dogs may react to the metal plate, causing swelling, discomfort, or stiffness in the leg.
• Implant failure – Although rare, this serious issue happens when screws loosen or the plate shifts, requiring corrective surgery.
• Infection involving the implant – If the implant site gets infected, the implant might need to be removed after the bone has healed.

If your dog experiences ongoing pain, lameness, or swelling around the implant site months after surgery, your vet may suggest X-rays to check the implant's condition. If needed, the plate can be removed once the bone is fully healed, typically 6-12 months after the operation.

When to Restart Physical Therapy If Recovery Stalls

Rehabilitation is essential for a dog’s recovery after TPLO surgery. If progress slows or mobility is still limited after six weeks, your vet may recommend starting a structured physical therapy plan. Rehab options include:

• Hydrotherapy (underwater treadmill or swimming) to build strength with little joint stress
• Balance training using wobble boards or uneven surfaces to enhance stability
• Laser therapy to reduce inflammation and speed up healing
• Massage and stretching exercises to prevent stiffness and muscle loss

If your dog has trouble bearing weight, limps often, or seems unwilling to walk even after resting, a tailored rehab program can help significantly. Lack of progress after two months may suggest joint stiffness, muscle loss, or lingering pain, all of which need professional evaluation.

Preventing Long-Term Complications

Most TPLO surgeries are very successful, but long-term care is crucial to keep your dog pain-free. To prevent future knee problems:

• Keep your dog at a healthy weight to reduce stress on the joints.
• Continue low-impact exercises like swimming or gentle walks to maintain strength.
• Avoid excessive jumping or high-impact activities, especially for older dogs.
• Provide joint supplements like glucosamine and chondroitin to support cartilage health.

By staying proactive and watching for potential issues, you can ensure your dog has the best possible outcome after TPLO surgery.

Conclusion

Recovering from TPLO surgery requires time, patience, and dedication, but the results are truly rewarding. While the first few weeks need strict rest and careful monitoring, you will start to see gradual improvements. By following a structured recovery plan, your dog can regain full mobility and return to an active, pain-free life.

Regular veterinary check-ups and, if needed, physical therapy are crucial for proper healing. Controlled exercise, a balanced diet, and long-term joint care help prevent complications and support overall joint health.

Trust the process, stay consistent with post-op care, and don’t hesitate to seek veterinary advice if you have concerns. With time and the right approach, your dog will be back to running, playing, and enjoying life again—stronger than ever.

FAQs

How long does it take for a dog to fully recover from TPLO surgery?

Full recovery from TPLO surgery usually takes 3 to 6 months. Most dogs regain significant mobility by 8 weeks, but complete bone healing and muscle strength restoration take several months. Regular follow-ups, controlled exercise, and rehabilitation are important for a smooth recovery. High-impact activities should only resume once the vet confirms proper healing through X-rays.

Can my dog walk right after TPLO surgery?

Most dogs will be unable or reluctant to walk immediately after surgery due to the effects of anesthesia and post-operative pain. However, within a few days, they usually begin toe-touching. By 2 weeks, light weight-bearing starts, and controlled short leash walks are allowed. Full, unrestricted walking takes several weeks, depending on healing progress and physical therapy.

When can my dog start running again?

Running should be avoided until at least 12 to 16 weeks post-surgery, and only with vet approval. By 3 to 6 months, most dogs can resume normal activities, but high-impact play should be introduced gradually. Sudden sprinting, jumping, or rough play too early can cause setbacks or issues with the implant.

How can I prevent complications after TPLO surgery?

Strict crate rest, controlled leash walks, and proper incision care are essential in the first few weeks. Use an E-collar to stop licking and follow all medication and rehab instructions. Look out for signs of infection, swelling, or limping. Keep your dog at a healthy weight and stick to a structured physical therapy plan for the best results.

Does TPLO surgery prevent arthritis in dogs?

TPLO surgery does not completely prevent arthritis, but it slows down its progression by stabilizing the knee joint and reducing abnormal movement. Dogs who undergo TPLO have better long-term joint function and experience less pain compared to untreated CCL injuries. Maintaining a healthy weight and providing joint supplements can further slow the development of arthritis.

Tibial Plateau Leveling Osteotomy (TPLO) is a surgery used to treat cranial cruciate ligament (CCL) tears in dogs. Unlike traditional methods that try to replace or mimic the damaged ligament, TPLO changes how the knee joint works to restore stability.

The procedure involves cutting the top part of the tibia (shin bone) and rotating it to a flatter position. This change reduces the natural forward sliding motion of the femur over the tibia, removing the need for the CCL. A special bone plate and screws hold the new position, allowing the bone to heal over time.

TPLO is considered better than traditional extracapsular repairs, which use artificial sutures to mimic the ligament’s function. Those methods can fail in active or large dogs. TPLO offers better long-term stability, faster recovery, and a lower risk of complications, making it the preferred choice for many veterinarians treating CCL injuries.

‍

Function of the Cranial Cruciate Ligament (CCL)

The Cranial Cruciate Ligament (CCL) is a key stabilizing part of a dog's knee (stifle) joint. It connects the femur (thigh bone) to the tibia (shin bone) and prevents excessive forward movement (tibial thrust) and rotation of the tibia when the dog walks, runs, or jumps. The CCL also helps distribute weight evenly across the joint, reducing stress on cartilage and minimizing wear over time.

When the CCL ruptures, the knee joint becomes unstable. Without this ligament, the femur slides abnormally over the tibia, causing pain, inflammation, and lameness. Dogs with a CCL tear may limp, have trouble bearing weight on the affected leg, and avoid activities like running or jumping. Over time, instability leads to arthritis, worsening discomfort and mobility.

CCL injuries greatly affect a dog's ability to move comfortably. Many dogs compensate by shifting weight to the opposite leg, increasing the risk of injuring the other knee. If left untreated, a torn CCL can cause chronic pain, muscle loss, and permanent joint damage. Surgical intervention, such as TPLO, is often the best option to restore knee function, relieve pain, and help dogs regain an active lifestyle.

Indications for TPLO Surgery: Which Dogs Need It?

TPLO surgery is most commonly recommended for large and active dog breeds, as they are more prone to cranial cruciate ligament (CCL) injuries due to their weight and activity levels.

Breeds like Labrador Retrievers, Golden Retrievers, Rottweilers, German Shepherds, and Boxers are at higher risk. However, TPLO can also be beneficial for medium-sized and small dogs, especially those with persistent knee instability.

Common Symptoms of a Torn CCL

• Limping or favoring one leg, especially after exercise
• Stiffness after resting, particularly in the morning
• Swelling and pain around the knee joint
• Difficulty rising, jumping, or using stairs
• Progressive worsening of lameness over time

When Is TPLO Surgery Necessary?

A veterinary evaluation is essential to determine the best treatment approach. TPLO is typically recommended if:

• The dog is large or highly active, where other repairs may fail
• There is significant knee instability affecting mobility
• Conservative management (rest, pain medication, and physiotherapy) has not improved symptoms

When Conservative Management May Work

For small dogs (under 30 lbs) or older, less active dogs, non-surgical options such as joint supplements, anti-inflammatory medications, weight management, and physical therapy may be considered. However, these methods do not fix the underlying instability, and arthritis will progress over time.

For high-energy or large dogs, TPLO remains the gold standard because it restores stability, allowing them to regain normal movement and minimize arthritis risk.

Mechanism of TPLO Surgery

Tibial Plateau Leveling Osteotomy (TPLO) is a surgery that aims to stabilize the knee joint by changing how the tibia (shin bone) works. Normally, when a dog walks, the femur (thigh bone) slides down the tibia because of the natural slope of the tibial plateau. The cranial cruciate ligament (CCL) stops this forward movement, keeping the knee stable.

‍

‍

How TPLO Alters the Tibial Plateau Angle

In TPLO, a curved cut (osteotomy) is made in the top portion of the tibia, allowing the surgeon to rotate the bone and reduce the tibial plateau angle (TPA) to nearly level (5-7 degrees from 20-30 degrees in most dogs). This new position eliminates the forward sliding motion (cranial tibial thrust) that occurs when the CCL is torn.

Why the CCL Is No Longer Needed

After TPLO, the knee no longer relies on the CCL for stability because the new bone alignment prevents abnormal movement. The femur rests in a neutral position, and weight-bearing forces are transferred evenly across the joint. The cut bone is then stabilized with a metal plate and screws, allowing it to heal in its new position.

Biomechanics in Simple Terms

Before TPLO, a torn CCL allows the tibia to slide forward with each step, causing pain and instability. After TPLO, the adjusted bone alignment prevents this sliding motion, making the knee function normally even without the ligament. This technique is particularly effective in large, active dogs, offering long-term stability and reducing the risk of arthritis progression.

TPLO Surgical Procedure Steps

Pre-Surgical Preparations

Before TPLO surgery, a veterinarian performs a thorough examination, including:

• X-rays of the knee to assess the tibial plateau angle and confirm CCL rupture.
• Blood tests to ensure the dog is healthy for anesthesia.
• Fasting for 8-12 hours before surgery to prevent complications.
• General anesthesia is administered, and the leg is shaved and disinfected.

Step-by-Step Breakdown

1. Making the Curved Cut in the Tibia
   
   • A semi-circular osteotomy (bone cut) is made in the upper tibia using a specialized saw. This allows the surgeon to reposition the tibial plateau.
2. Rotating the Tibial Plateau
   
   • The cut bone is rotated to reduce the tibial plateau angle from its natural slope (20-30 degrees) to a nearly level position (5-7 degrees).
   • This prevents the femur from sliding forward, eliminating the need for the CCL.
3. Fixing the New Position
   
   • A metal plate and screws secure the rotated tibial plateau in place. These implants provide stability while the bone heals.

TPLO Surgical Duration and Hospital Stay

• TPLO surgery usually takes 60-90 minutes, depending on the dog's size and the complexity of the procedure.
• Most dogs stay in the hospital for 12-24 hours after surgery for pain management and monitoring.
• Full recovery takes 8-12 weeks, with limited activity and follow-up X-rays to ensure proper healing.

Why TPLO Surgery is Preferred Over Other Methods

TPLO surgery is considered the gold standard for treating cranial cruciate ligament (CCL) injuries, especially in large and active dogs. It provides superior joint stability and long-term success compared to other methods like Tibial Tuberosity Advancement (TTA), lateral suture stabilization, and conservative management.

Comparison with Other Techniques

1. Tibial Tuberosity Advancement (TTA)
   
   • Like TPLO, TTA alters knee mechanics but focuses on shifting the patellar tendon’s force rather than leveling the tibial plateau.
   • Less effective for severe arthritis or extreme tibial slopes.
   • Similar recovery time, but TPLO is often preferred for better long-term stability.
2. Lateral Suture Stabilization (Extracapsular Repair)
   
   • Uses an artificial suture outside the joint to mimic the CCL.
   • Less reliable in large, active dogs, as the suture can stretch or break over time.
   • Suitable for small dogs (<30 lbs) but not ideal for high-energy breeds.
3. Conservative Management (Rest, Medication, Therapy)
   
   • Does not restore knee stability, leading to progressive arthritis.
   • May be an option for very small or senior dogs, but often results in chronic pain and reduced mobility.

Why TPLO is Preferred

• Higher success rate (~90-95%) with long-term joint stability.
• Faster recovery (dogs can bear weight within days, full recovery in ~12 weeks).
• Best suited for large and active dogs, as it withstands high physical demands better than other methods.

Benefits of TPLO Surgery

Restores Joint Stability for Normal Movement: TPLO surgery eliminates the instability caused by a torn cranial cruciate ligament (CCL) by changing the biomechanics of the knee. By leveling the tibial plateau, the femur no longer slides forward, allowing smooth, pain-free movement. This lets dogs return to normal activities like running, jumping, and playing after recovery.

Reduces Long-Term Arthritis Risk: A torn CCL leads to chronic joint instability, which accelerates cartilage damage and arthritis. TPLO provides permanent knee stability, significantly slowing down the degenerative changes that cause pain and stiffness. While arthritis can still develop, it progresses much slower compared to untreated or poorly repaired injuries.

Faster Recovery Compared to Traditional Repairs: Unlike lateral suture techniques, which rely on an artificial ligament that can weaken or break, TPLO stabilizes the knee through bone healing. Dogs start bearing weight within days after surgery, and most regain normal mobility within 8-12 weeks. This is faster and more reliable than other surgical methods, especially for large, active dogs.

Higher Success Rates and Better Long-Term Outcomes: Studies show TPLO has a 90-95% success rate, with fewer complications and a longer-lasting solution than alternative techniques. Dogs undergoing TPLO generally have a higher chance of returning to full activity, making it the preferred option for high-energy or working dogs.

Potential Risks and Complications of TPLO Surgery

While TPLO surgery has a high success rate, complications can still occur, including:

• Implant Failure (Plate or Screw Loosening) – If a dog is too active too soon, the metal implants can shift or break.
• Bone Fractures – The tibia is weakened during surgery, and excessive strain may cause small fractures, especially in high-energy dogs.
• Delayed Bone Healing – Some dogs, particularly older ones or those with underlying conditions, may take longer to recover.

Post-surgical infections are one of the biggest concerns in orthopedic surgeries, but many veterinary surgeons now use Simini Protect Lavage, a non-antibiotic surgical lavage solution. Simini reduces bacterial contamination and biofilms, lowering infection risks significantly. This makes TPLO surgery safer and helps prevent complications that could delay recovery.

How to Minimize Risks with Proper Post-Op Care

• Strict activity restriction for 8-12 weeks to prevent implant damage.
• Regular vet check-ups and follow-up X-rays to monitor healing.
• Wound care and infection prevention – Keeping the incision clean and using solutions like Simini helps reduce infection risk.
• Controlled physical therapy – Gentle exercises, under veterinary guidance, help regain mobility without stressing the joint.

With the right precautions and the use of advanced infection control methods like Simini Protect Lavage, most dogs recover successfully with minimal complications.

Success Rates and Long-Term Outcomes of TPLO Surgery

High Success Rate and Improved Mobility: TPLO surgery has a 90-95% success rate, making it one of the most reliable treatments for cranial cruciate ligament (CCL) injuries in dogs. Most dogs experience significant pain relief and restored joint stability within weeks. Studies show that 85-90% of dogs regain near-normal function, allowing them to walk, run, and play without limping or discomfort.

Long-Term Prognosis: Can Dogs Return to Normal Activity? For most dogs, TPLO provides a permanent solution, allowing them to return to normal activity levels once fully healed. Large, active, and working dogs particularly benefit from TPLO, as it withstands high-impact movement better than other surgical options. With proper post-op care, arthritis progression is slowed, and joint function remains strong for years.

Cases Where Additional Treatment May Be Needed

While TPLO is highly effective, some dogs may require further treatment, such as:

• Severe pre-existing arthritis – Some dogs may need joint supplements, weight management, or physical therapy for long-term comfort.
• Implant-related complications – Rare cases of plate or screw loosening may require revision surgery.
• Bilateral CCL injuries – If both knees are affected, a second TPLO may be needed once the first knee has healed.

With proper rehabilitation and veterinary follow-ups, TPLO surgery allows dogs to live pain-free, active lives with minimal long-term issues.

FAQs

How long does it take for a dog to recover from TPLO surgery?

Full recovery from TPLO surgery takes about 8-12 weeks. Most dogs start bearing weight within a few days, but strict activity restriction is necessary for proper healing. By 6-8 weeks, follow-up X-rays check bone healing. Gradual return to normal activity happens after 12 weeks, with complete muscle recovery taking up to 6 months in some cases.

Can a dog walk immediately after TPLO surgery?

Yes, most dogs can bear weight on the leg within 24-72 hours after TPLO surgery. However, their movement should be strictly limited to prevent complications. Short, controlled leash walks for bathroom breaks are allowed, but running, jumping, and stairs must be avoided for at least 8-12 weeks to ensure proper healing.

Does TPLO surgery prevent arthritis in dogs?

TPLO surgery does not completely prevent arthritis but significantly slows its progression. By stabilizing the knee joint, TPLO reduces abnormal wear on cartilage, which helps minimize long-term joint damage. However, some arthritis may still develop, especially if the injury was untreated for a long time before surgery.

Will my dog need physical therapy after TPLO surgery?

Yes, physical therapy helps speed recovery and improves mobility. Controlled range-of-motion exercises, underwater treadmill therapy, and strength training can reduce stiffness and rebuild muscle. While not always required, veterinary-supervised rehab improves outcomes, especially in large or highly active dogs.

Can a dog tear the CCL in the other leg after TPLO?

Yes, dogs that rupture one CCL have a 40-60% chance of tearing the other within two years. TPLO surgery helps restore stability in the operated leg, but increased weight-bearing on the opposite limb can strain the remaining CCL. Weight management, joint supplements, and controlled activity can help reduce this risk.

Is Bruising Normal After TPLO Surgery?

Yes, bruising after TPLO surgery is common and occurs due to tissue manipulation, blood vessel disruption, and surgical trauma. Mild to moderate bruising around the incision site typically fades within 1–2 weeks. However, excessive bruising, swelling, or warmth may indicate infection or complications. If bruising worsens or persists beyond two weeks, consult your veterinarian for further evaluation.

‍

Tibial Plateau Leveling Osteotomy (TPLO) is a surgery used to treat cranial cruciate ligament (CCL) injuries in dogs. Instead of replacing the damaged ligament, TPLO changes the knee's mechanics by cutting and rotating the tibia to stabilize the joint. This procedure greatly improves mobility and reduces pain, making it one of the most effective treatments for CCL injuries.

While TPLO is often successful, complications can occur. Problems may arise from surgical errors, implant issues, infections, or improper post-operative care. These issues can cause severe pain, lameness, and reduced mobility, requiring immediate attention.

Recognizing symptoms of TPLO failure early is crucial. Pet owners and veterinarians must closely monitor recovery to spot signs of complications. Identifying problems early can prevent further damage, improve treatment outcomes, and sometimes avoid the need for corrective surgery. Being aware ensures a better quality of life for the dog.

Early Warning Signs of TPLO Failure

Recognizing early symptoms of TPLO failure is crucial for timely intervention. While mild discomfort and swelling are normal during the initial recovery period, persistent or worsening symptoms may indicate complications.

Persistent Lameness or Limping

Mild lameness is expected for the first few weeks after TPLO surgery. Most dogs show significant improvement within 8–12 weeks. However, if limping persists beyond this period or worsens, it may signal poor bone healing, implant failure, or an underlying infection.

Signs of concern include the dog favoring the other leg, difficulty bearing weight, or sudden regression in mobility. If the leg does not seem to be healing as expected or if there is no gradual improvement, further veterinary evaluation is necessary. X-rays can help determine if the bone is healing correctly or if complications exist.

Pain During Movement or Reluctance to Use the Affected Leg

Some discomfort is normal post-surgery, but persistent pain when walking, climbing stairs, or standing up may indicate a problem. If a dog avoids using the leg weeks after surgery or shows hesitation in movement, it could be due to implant irritation, improper bone healing, or inflammation. Pain when touching the leg, vocalization, or a stiff gait are red flags.

A dog that initially improves but later develops increased pain needs urgent assessment. A vet may perform imaging and physical exams to check for implant loosening, joint infections, or soft tissue complications affecting recovery.

Swelling Around the Surgical Site

Mild swelling is expected for a few days post-op but should gradually decrease. If swelling persists, worsens, or becomes firm and painful, it may indicate a complication. Excessive swelling could result from implant irritation, fluid buildup, or infection. If the area feels warm or if swelling is accompanied by lameness, immediate veterinary attention is necessary.

A seroma (fluid accumulation) may require drainage, while severe swelling linked to infection or implant rejection may necessitate medical intervention or revision surgery. Monitoring the surgical site daily helps detect abnormal swelling before it leads to more serious issues.

Signs of Infection (Redness, Discharge, Heat)

Post-surgical infections can occur around the incision or deep within the joint, though they are less common when Simini Protect Lavage is used, as it helps reduce bacterial contamination during surgery. However, infections can still develop due to improper wound care, immune response issues, or implant-related complications.

Early symptoms include redness, swelling, heat, and discharge from the incision site. A foul odor, increased pain, or excessive licking are also concerning. If untreated, infections can spread, leading to implant instability, fever, lethargy, and appetite loss. In severe cases, infection may require implant removal and surgical intervention.

Prompt antibiotic therapy is essential to control bacterial growth. Regular wound monitoring, proper hygiene, and early veterinary attention help prevent minor infections from escalating.

Structural and Mechanical Failures

These complications indicate that the surgical repair is not functioning correctly, leading to ongoing instability and pain. Unlike early post-op discomfort, structural failures can cause long-term mobility issues and may require corrective surgery.

Recurrent Knee Joint Instability

After TPLO, the knee joint should be stable due to the new tibial alignment. However, if a dog shows difficulty walking, wobbling, or an unstable gait, it may signal failed bone healing or implant issues. Instability can result from improper fusion of the cut tibia, loose screws, or excessive strain on the joint.

A dog may shift weight frequently or show reluctance to move, indicating mechanical failure. X-rays and physical exams help confirm whether the joint is unstable. Left untreated, instability can lead to severe arthritis, chronic pain, and reduced mobility, making early intervention critical.

Meniscal Injury or Tear

Meniscal damage is a common complication following TPLO surgery, as this cartilage helps cushion the knee joint. A torn meniscus can occur due to improper knee mechanics or residual instability. Symptoms include a sudden return of lameness, difficulty bearing weight, or a clicking or popping sound when the knee moves.

Dogs may yelp when standing or walking and may become more inactive due to pain. A torn meniscus may require surgical removal or repair to restore function. Without treatment, the condition can worsen, leading to chronic discomfort and long-term joint deterioration.

Post-Operative Meniscal Tear

A meniscal tear can occur at the time of surgery (primary tear) or develop later due to knee instability (secondary tear). A secondary meniscus tear is particularly concerning, as it often happens weeks or months after the initial procedure. This results in immediate pain, limping, and reluctance to move.

Dogs with a new meniscus tear may suddenly regress in their recovery, refusing to put weight on the leg despite previous improvements. Surgical intervention is often required to remove the damaged cartilage and restore comfort. Regular post-op checkups help detect meniscal issues before they become severe.

Implant Loosening, Bending, or Breakage

TPLO implants, including plates and screws, must remain secure for proper healing. If an implant loosens, bends, or breaks, the bone may fail to stabilize, causing pain and mobility loss. Signs include swelling, limping, reluctance to use the leg, or a clicking sensation in the joint. Implant failure can result from improper post-op care, excessive activity, or underlying bone weakness.

Overweight dogs and those resuming activity too soon are at higher risk. X-rays are necessary to confirm implant damage. Severe cases may require revision surgery to replace or secure the implants and restore knee stability.

Advanced TPLO Failure Symptoms

These symptoms indicate severe complications requiring medical intervention. If TPLO failure progresses, a dog may experience chronic pain, loss of function, or permanent joint damage. Early detection is key to preventing irreversible issues.

Delayed Bone Healing or Nonunion

Bone healing after TPLO typically takes 8–12 weeks. However, some dogs experience delayed healing or nonunion, where the bone fails to fuse properly. Causes include poor nutrition, excessive movement, infections, or improper plate positioning.

Dogs with nonunion may show persistent limping, pain, or swelling at the surgical site. X-rays can confirm if the bone is healing correctly. Nonunion requires intervention, such as adjusting activity levels, improving diet, or, in severe cases, revision surgery. If left untreated, it can lead to chronic instability and increased risk of implant failure.

Muscle Atrophy Around the Thigh

Muscle atrophy occurs when a dog avoids using the affected leg, leading to gradual muscle loss in the thigh. Mild atrophy is normal post-surgery but should improve with rehabilitation. However, progressive muscle loss suggests long-term mobility issues, improper healing, or ongoing pain. Dogs with severe atrophy may struggle with balance, fatigue quickly, or rely heavily on the other leg.

Physical therapy, controlled exercise, and pain management help restore muscle strength. If left unaddressed, muscle atrophy can make recovery difficult and reduce overall limb function, leading to permanent weakness.

Recurrent or Persistent Mobility Issues

Most dogs regain near-normal function within a few months after TPLO. However, if mobility issues persist beyond this period, it could indicate implant failure, arthritis, or joint instability. Some dogs may continue limping, struggle with stairs, or hesitate to run and jump. Persistent dysfunction suggests that TPLO did not fully correct the knee mechanics, leading to long-term discomfort.

Chronic instability may also cause secondary joint problems. Veterinary evaluation, including X-rays and orthopedic exams, is needed to determine if additional treatment or revision surgery is required. Without intervention, mobility may decline further, affecting quality of life.

Signs of Implant Failure (Mild Discomfort to Acute Pain)

Implant failure can range from mild discomfort to severe pain. Early signs include persistent limping, swelling, and difficulty bearing weight. If an implant loosens or breaks, symptoms can suddenly worsen, causing acute distress, refusal to move, or vocalization when walking. Clicking or grinding noises may also indicate implant instability.

Severe cases require urgent veterinary care, as implant failure can lead to bone fractures or infection. X-rays confirm implant integrity, and treatment may involve pain management, restricted movement, or surgical revision. Delayed care increases the risk of complications, making early detection crucial.

Potential Need for Revision Surgery

Revision TPLO surgery is necessary when the original procedure fails due to nonunion, implant failure, or chronic instability. This involves replacing damaged implants, repositioning the tibial cut, or addressing infections. Revision surgery is often more complex than the initial procedure and requires strict post-op management.

Recovery may take longer, but successful revision can restore knee stability and improve function. If left untreated, TPLO failure can result in chronic pain, severe arthritis, or loss of mobility. A thorough veterinary evaluation determines if revision surgery is the best option for improving the dog’s quality of life.

When to See a Veterinarian

Pet owners should contact a veterinarian if their dog shows signs of worsening pain, persistent lameness beyond 12 weeks, or sudden regression in mobility after initial improvement.

Other concerning symptoms include swelling that does not subside, redness or discharge from the surgical site, difficulty bearing weight, or signs of infection like fever and lethargy. Any clicking or grinding sounds from the knee may indicate meniscal damage or implant instability, requiring immediate attention.

To confirm TPLO failure, veterinarians use diagnostic tests such as X-rays to assess bone healing and implant positioning, CT scans for detailed imaging of the knee structure, and joint fluid analysis to detect infections or inflammation. In severe cases, additional tests may be needed to evaluate soft tissue damage.

Early veterinary intervention can prevent further complications, reducing the need for complex revision surgery and ensuring a better long-term outcome for the dog.

Preventing TPLO Failure

Proper post-operative care is essential for preventing TPLO failure and ensuring a smooth recovery. Strict activity restriction is crucial in the first 8–12 weeks—dogs should avoid running, jumping, or using stairs. A knee brace may provide additional joint support, especially for highly active dogs. Physical therapy helps restore strength and mobility while minimizing the risk of complications.

To promote proper healing, a nutrient-rich diet with adequate protein, calcium, and joint supplements (such as glucosamine) supports bone repair. Regular follow-up vet visits allow for X-ray monitoring to confirm bone fusion and implant stability.

Recognizing early red flags—such as persistent limping, swelling, or signs of infection—can prevent serious complications. Pet owners should check the incision site daily and report any unusual symptoms.

By following post-op guidelines and addressing concerns promptly, the risk of TPLO failure can be significantly reduced, leading to a successful recovery and long-term joint stability.

FAQs

What happens if TPLO fails in dogs?

If TPLO fails, the affected leg may remain unstable, leading to chronic pain, persistent lameness, and arthritis. The knee joint may not heal properly, causing difficulty in movement. In severe cases, implant failure or bone nonunion may require revision surgery to correct the issue. If left untreated, TPLO failure can significantly impact a dog’s mobility and overall quality of life.

What percent of TPLO surgeries fail?

TPLO has a high success rate, with over 90-95% of dogs recovering well. However, failure can occur in 5-10% of cases due to infections, implant loosening, meniscal injuries, or delayed bone healing. Factors like improper post-op care, excessive activity, or underlying health conditions increase the risk. Early detection and proper recovery management can reduce complications and improve surgical outcomes.

How to tell if a dog's ACL surgery failed?

Signs of TPLO failure include persistent limping, swelling, pain, and reluctance to use the affected leg beyond the expected recovery period. Clicking sounds in the joint, excessive stiffness, or visible implant issues may also indicate failure. If a dog’s condition worsens instead of improving, a vet should perform X-rays or CT scans to assess healing and detect complications.

Why is my dog limping 2 years after TPLO surgery?

Limping two years post-TPLO may result from arthritis, implant irritation, meniscal damage, or muscle atrophy. Some dogs develop scar tissue or secondary joint issues that cause discomfort. If limping is sudden, it could indicate a late meniscus tear or implant problem. A veterinary exam, including imaging, can determine the cause and guide appropriate treatment, such as pain management or revision surgery.

What does a failed TPLO look like?

A failed TPLO often presents as persistent pain, joint instability, swelling, or difficulty bearing weight on the affected leg. Dogs may show progressive lameness, reluctance to move, or audible joint clicking. Severe cases may involve implant loosening, infection, or nonunion of the bone, which can be confirmed through X-rays or CT scans. Early intervention is crucial to prevent worsening complications.

Can TPLO surgery be redone?

Yes, revision TPLO surgery can be performed if the initial procedure fails. This may involve removing or replacing implants, repositioning the tibial cut, or addressing infections. Revision surgery is often more complex and requires strict post-op care. In some cases, alternative treatments like custom knee braces or joint fusion procedures may be considered if TPLO cannot be successfully redone.

What is the alternative to TPLO on dogs?

Alternatives to TPLO include Lateral Suture Stabilization (Extracapsular Repair), Tibial Tuberosity Advancement (TTA), and CBLO (Cora-Based Leveling Osteotomy). These procedures also stabilize the knee but may be better suited for smaller dogs or specific cases. Non-surgical options like custom braces, weight management, and physical therapy may help in mild or inoperable cases, though they do not provide the same level of stability as TPLO.

How long can a dog go without TPLO surgery?

Dogs with a torn CCL can survive without TPLO, but untreated ligament injuries lead to chronic pain, arthritis, and joint deterioration. Some small or inactive dogs may adapt with braces, weight control, and pain management, but larger, active dogs usually require surgery for long-term stability. Without intervention, progressive joint damage can severely impact mobility, making walking difficult or painful over time.
