TPLO (Tibial Plateau Leveling Osteotomy) surgery is a common procedure to stabilize a dog's knee after a cranial cruciate ligament (CCL) rupture. It involves cutting and repositioning the tibia to reduce strain on the ligament, allowing for better joint function. Like any surgery, TPLO has a risk of complications, with incision infections being a primary concern.

Infections can happen due to bacterial contamination during surgery, improper post-op care, excessive licking or chewing of the incision, or underlying conditions like diabetes or a weakened immune system. Signs of infection include redness, swelling, warmth, discharge, and delayed healing.

The risk of infection after TPLO is relatively low, occurring in about 3-10% of cases. Factors like surgical technique, sterile conditions, and strict post-operative management greatly affect the outcome. Early detection and quick treatment with antibiotics and wound care are crucial to prevent complications and ensure a successful recovery.

Symptoms and Warning Signs of TPLO Incision Infection

Recognizing the symptoms of an infection early is crucial for preventing complications after TPLO (Tibial Plateau Leveling Osteotomy) surgery. Infections can range from mild to severe, potentially affecting healing and the long-term success of the procedure. Understanding the difference between early and advanced signs can help ensure timely intervention.

Early Signs of Infection

In the initial stages, an infection may present with mild symptoms that can sometimes be mistaken for normal healing. These include:

• Redness and swelling around the incision site, which may be slightly warm to the touch.
• Mild pain or tenderness, which persists beyond the expected post-surgical discomfort.
• Clear or slightly yellow discharge, which may indicate the presence of bacteria.

If detected at this stage, infections are often manageable with topical treatments, antibiotics, and proper wound care.

Advanced Signs of Infection

As an infection worsens, more severe symptoms may develop, indicating deeper tissue involvement and potential systemic infection. These include:

• Thick, pus-like discharge from the incision, often accompanied by a foul odor.
• Significant swelling and warmth, which may extend beyond the incision area.
• Fever and lethargy, as the body mounts an immune response.
• Increased lameness or reluctance to bear weight, signaling pain or joint involvement.

Advanced infections require urgent veterinary care, as untreated cases can lead to delayed healing, implant complications, or systemic illness. Immediate intervention, such as antibiotics, wound debridement, or even surgical revision, may be necessary.

Monitoring the incision closely in the weeks following TPLO surgery is essential. Any changes in the wound’s appearance, excessive discomfort, or behavioral changes in your dog should be reported to a veterinarian promptly to prevent complications.

Causes of TPLO Incision Infection

A TPLO (Tibial Plateau Leveling Osteotomy) incision infection can occur due to various factors, either during the surgery or in the post-operative recovery period. Identifying and minimizing these risks is essential for ensuring a smooth healing process.

Bacterial Contamination During or After Surgery

Despite strict sterile protocols, bacteria can sometimes enter the surgical site during the procedure. This can happen due to contamination from the skin, surgical instruments, or even the surrounding environment. Post-operatively, improper wound care or exposure to unclean surfaces can introduce bacteria, increasing infection risk.

Poor Post-Op Wound Care

Proper post-operative care is critical to prevent infection. Failure to keep the incision clean and dry, skipping prescribed antibiotics, or neglecting follow-up visits can allow bacteria to proliferate. Owners must follow all veterinary instructions carefully, including cleaning protocols and medication administration.

Licking or Chewing the Incision Site

Dogs instinctively lick their wounds, which can introduce bacteria from their mouths into the incision. Excessive licking or chewing can also cause trauma to the site, delaying healing. The use of an Elizabethan collar (E-collar) or medical pet shirt is essential to prevent self-inflicted wound contamination.

Moisture Buildup Around the Incision

A damp environment around the incision can promote bacterial growth. Moisture can accumulate from bathing, wet bedding, or excessive sweating, making it essential to keep the area dry until fully healed.

Underlying Health Conditions

Dogs with pre-existing conditions such as diabetes, Cushing’s disease, or immune disorders have a higher risk of infection due to impaired wound healing. Such cases require extra vigilance in monitoring for signs of infection.

Implants and Their Role in Infection Risk

The metal implants used in TPLO surgery can serve as a surface for bacterial adhesion. If bacteria form a biofilm on the implant, it can lead to a deep-seated infection that may require implant removal or surgical revision.

To minimize this risk, many surgeons use Simini Protect Lavage, a non-antibiotic surgical lavage designed to reduce bacterial contamination and prevent biofilm formation. Unlike traditional solutions, Simini Protect Lavage actively disrupts bacterial adhesion, helping to lower infection risks without contributing to antibiotic resistance. Its use in TPLO and other orthopedic procedures has shown promising results in enhancing post-surgical outcomes.

Preventing infection requires a combination of strict surgical protocols, diligent post-op care, and close monitoring of the incision site for any signs of complications.

How TPLO Infections Are Diagnosed

Diagnosing a TPLO incision infection requires a thorough evaluation by a veterinarian to determine the severity and appropriate treatment plan. Early detection is key to preventing complications such as delayed healing, deep tissue infections, or implant failure.

Physical Examination

The first step in diagnosing an infection is a detailed physical examination of the incision site. The veterinarian will check for common signs of infection, including:

• Redness and swelling around the incision.
• Abnormal discharge (pus, thick yellow fluid, or foul-smelling secretions).
• Increased warmth in the surrounding tissue.
• Pain response when the area is gently palpated.
• Signs of systemic illness, such as fever or lethargy.

Diagnostic Tests

If an infection is suspected, further diagnostic tests help confirm the presence and extent of the infection.

• Wound Culture and Sensitivity Test - A swab of the incision site is collected to identify the specific bacterial strain causing the infection. This helps determine the most effective antibiotic treatment.
• Complete Blood Count (CBC) - Blood tests check for elevated white blood cell counts (WBCs), which indicate an immune response to infection. Other markers, such as increased neutrophils, may suggest a bacterial infection.
• X-rays or Advanced Imaging - If the infection has progressed or involves the surgical implants, X-rays or ultrasound imaging may be used to assess deep tissue involvement. In some cases, an infection can lead to osteomyelitis (bone infection) or implant loosening, requiring further surgical intervention.

Prompt and accurate diagnosis ensures that treatment is initiated quickly, reducing the risk of complications and improving the chances of a full recovery.

Potential Complications of an Untreated TPLO Incision Infection

If a TPLO incision infection is left untreated, it can lead to serious complications that may jeopardize the success of the surgery and the dog’s long-term mobility. Early intervention is crucial to prevent these risks.

Implant Failure and the Need for Removal or Revision Surgery

TPLO surgery involves the placement of metal implants (plates and screws) to stabilize the tibia. If bacteria colonize the implant, they can form a biofilm, making the infection difficult to treat with antibiotics alone. This can lead to implant loosening or failure, requiring removal or revision surgery to replace the affected hardware. A second surgery increases recovery time and risk of further complications.

Deep Bone Infection (Osteomyelitis)

When an infection spreads beyond the incision site into the bone tissue, it can cause osteomyelitis, a severe and persistent infection. Bone infections are challenging to treat and often require long-term antibiotics, surgical debridement, or even partial bone removal in extreme cases. Osteomyelitis can significantly delay healing and may compromise limb function.

Delayed Healing, Prolonged Pain, and Lameness

An untreated infection slows down wound healing, leading to persistent inflammation, chronic pain, and prolonged lameness. Infections interfere with the body’s natural healing process, increasing the risk of poor scar formation and weakening the stability of the joint. This can result in long-term mobility issues, affecting the dog’s quality of life.

Risk of Systemic Infection (Sepsis)

If bacteria enter the bloodstream, the infection can become systemic, leading to sepsis, a life-threatening condition. Sepsis causes widespread inflammation, organ dysfunction, and severe illness. Immediate hospitalization, intravenous antibiotics, and aggressive supportive care are required in such cases.

Preventing complications requires early diagnosis, strict post-op care, and immediate treatment of any signs of infection to ensure a smooth recovery.

Treatment Options for TPLO Incision Infections

A TPLO incision infection requires prompt and appropriate treatment to prevent complications and ensure proper healing. The treatment plan depends on the severity of the infection, the presence of bacterial colonization on the implants, and the dog’s overall health.

Antibiotic Therapy

Antibiotics are the first line of treatment for a TPLO incision infection. The choice of antibiotic depends on wound culture and sensitivity testing, ensuring effective targeting of the bacteria.

• Oral antibiotics (e.g., cephalexin, clindamycin, or enrofloxacin) are commonly prescribed for mild to moderate infections.
• Topical antibiotics (e.g., silver sulfadiazine or mupirocin) may be used to manage surface-level infections.
• If the infection is deep-seated or spreading, intravenous (IV) antibiotics may be required for better systemic control.

Wound Cleaning and Care

Proper wound care helps clear bacteria and promote healing. This includes:

• Cleaning the incision with veterinary-approved antiseptic solutions (chlorhexidine or diluted povidone-iodine).
• Avoiding excessive moisture buildup around the wound.
• Preventing licking or chewing with an Elizabethan collar (E-collar) or medical pet shirt.
• Ensuring the bandage (if used) is clean and changed as recommended by the veterinarian.

Pain Management

Infections cause inflammation and discomfort, so pain relief is an important part of treatment.

• Non-steroidal anti-inflammatory drugs (NSAIDs) such as carprofen or meloxicam may be prescribed to reduce pain and swelling.
• If severe discomfort persists, stronger pain relievers may be necessary.

Surgical Intervention

For infections that do not respond to antibiotics or involve the implants, surgical intervention may be needed:

• Flushing and debridement – The vet may clean and remove infected tissue under anesthesia to prevent further bacterial spread.
• Implant removal or revision – If bacteria have colonized the TPLO plate and screws, implant removal may be necessary, followed by a prolonged course of antibiotics to clear the infection.

Timely and appropriate treatment is essential to prevent long-term complications and ensure a smooth recovery. Close veterinary supervision and adherence to post-op care instructions significantly improve outcomes.

When to Call Your Veterinarian

Recognizing the signs of a TPLO incision infection early and seeking veterinary care promptly can prevent serious complications. Certain symptoms indicate the need for immediate medical attention:

• Excessive swelling, redness, or warmth around the incision.
• Thick, pus-like discharge or a foul odor from the wound.
• Persistent pain or worsening lameness beyond the expected healing period.
• Fever, lethargy, or loss of appetite, which may indicate a systemic infection.
• Sudden changes in behavior, such as reluctance to move or increased sensitivity around the incision.

How Quickly Should an Infection Be Addressed?

If you notice any signs of infection, contact your veterinarian immediately. Mild infections caught early may be treated with antibiotics and wound care, but delays in treatment can lead to deeper infections, increasing the risk of implant failure or systemic illness.

What to Expect During a Vet Visit

Your veterinarian will:

• Perform a physical examination of the incision.
• Conduct diagnostic tests (wound cultures, blood tests, or X-rays) if needed.
• Prescribe antibiotics or pain medication based on the infection’s severity.
• Recommend wound cleaning protocols or, in severe cases, surgical intervention to remove infected tissue or implants.

Prompt veterinary care ensures a smoother recovery and reduces the risk of long-term complications.

Preventing TPLO Incision Infections

Preventing infection after TPLO surgery is crucial for ensuring a smooth recovery and avoiding complications. Proper post-operative care significantly reduces the risk of infection and promotes faster healing.

Proper At-Home Wound Care Routine

A clean and well-maintained incision site is essential for preventing bacterial growth. Follow these steps to ensure proper wound care:

• Inspect the incision daily for redness, swelling, or discharge.
• Use vet-approved antiseptic solutions if cleaning is necessary.
• Avoid touching the wound with unclean hands to prevent contamination.
• Follow the prescribed antibiotic regimen to eliminate any potential bacterial infections.

Importance of E-Collars to Prevent Licking

Dogs instinctively lick wounds, but their mouths contain bacteria that can introduce infection.

• An Elizabethan collar (E-collar) or medical pet shirt should be used at all times until the incision fully heals.
• Even brief periods of licking can introduce bacteria, delaying healing and increasing infection risk.

Keeping the Incision Dry and Clean

Moisture creates an ideal environment for bacterial growth, so it’s important to:

• Prevent the incision from getting wet—no bathing or swimming until cleared by the vet.
• Keep the bedding clean and dry to avoid contamination.
• If the incision gets wet, gently pat it dry with a clean, soft cloth.

Following Post-Op Care Instructions Strictly

Veterinary post-op guidelines should be followed precisely, including:

• Restricted activity to prevent excessive movement that could stress the incision.
• Proper medication schedules, including antibiotics and pain relievers.
• Scheduled follow-up visits to monitor healing progress.

Monitoring for Any Early Signs of Infection

Even with proper care, infections can still develop. Watch for:

• Redness, swelling, or discharge from the incision.
• Excessive licking or signs of discomfort around the area.
• Changes in behavior, such as lethargy or reluctance to move.

By taking proactive steps in at-home care, pet owners can significantly reduce the chances of post-operative infections and support a successful TPLO recovery.

FAQs

How do I know if my TPLO incision is infected?

A TPLO incision infection may show signs such as redness, swelling, warmth, and abnormal discharge (yellow, pus-like, or foul-smelling fluid). The incision may become painful, and your dog might show increased licking, lethargy, fever, or reluctance to walk. If you notice any of these symptoms, contact your veterinarian immediately for evaluation and treatment.

How do you treat a TPLO infection?

Treatment depends on the severity of the infection. Mild cases may be managed with oral antibiotics and wound cleaning, while severe infections might require intravenous antibiotics, wound flushing, or even implant removal if bacteria form a biofilm. Pain management and restricted movement are also essential for recovery. Early treatment ensures the best outcomes and prevents complications like deep bone infections or implant failure.

What to do if my dog's incision is infected?

If you suspect an infection, contact your veterinarian immediately. Avoid cleaning the wound with unapproved solutions, and prevent your dog from licking the incision by using an E-collar or protective covering. The vet may prescribe antibiotics, pain relief, or wound debridement depending on the infection's severity. Delaying treatment can worsen the infection and lead to complications.

How common is infection after TPLO surgery?

Infections after TPLO surgery are relatively uncommon, occurring in about 3-10% of cases. The risk increases with factors like poor post-op care, excessive licking, moisture exposure, or underlying health issues such as diabetes or immune suppression. Following strict wound care protocols and monitoring for early signs of infection significantly reduces the risk.

What is the infection rate for TPLO?

The infection rate for TPLO surgery ranges from 3-10%, depending on factors such as surgical technique, sterility, and post-operative care. Using advanced infection prevention methods, such as Simini Protect Lavage, proper antibiotic use, and strict wound monitoring, can help minimize infection risks. Prompt intervention at the first sign of infection is essential.

What does the start of an infected incision look like?

The early signs of an infected TPLO incision include increased redness, mild swelling, warmth, and clear to yellow discharge. The area may become more painful than expected during normal healing, and your dog may lick or chew the incision excessively. If left untreated, symptoms can worsen, leading to pus formation, odor, and systemic illness. Any suspicious changes should be evaluated by a veterinarian immediately.

Many pet owners choose Tibial Plateau Leveling Osteotomy (TPLO) to help their dogs regain mobility, but years later, they may question if it was the right decision. The main concerns are about arthritis, implant issues, and long-term joint function.

Studies show that over 90% of dogs regain full limb function within a year, and the long-term results are generally positive. However, mild arthritis is expected, even in successful cases.

Some owners reconsider TPLO because of implant rejection or ongoing lameness, but these cases are rare with proper post-op care. When combined with weight management and physical therapy, TPLO offers lasting relief, often keeping dogs active well into their senior years.

Understanding TPLO Surgery and Its Long-Term Impact

TPLO surgery is designed to stabilize the knee and restore mobility after a cranial cruciate ligament (CCL) tear. Unlike traditional repairs, TPLO permanently changes the knee’s biomechanics by altering the tibial plateau angle, which reduces strain on the joint.

While most dogs regain almost normal function, there are long-term factors to consider. Arthritis develops in nearly all cases, but its severity can vary. Implant wear or loosening is rare but can happen, especially in very active dogs. Another concern is compensatory injury; dogs that undergo TPLO on one leg have up to a 50% chance of tearing the CCL in the opposite knee within a few years.

Despite these risks, long-term studies confirm TPLO’s effectiveness in maintaining mobility and reducing chronic pain. With proper care, many dogs remain active for 8–10 years after surgery.

Long-Term Success Rates and Mobility

For most dogs, TPLO isn't just a short-term solution—it offers long-lasting improvements in mobility, keeping them active well into their senior years.

How Well Do Dogs Recover 5–10 Years After TPLO?

Long-term studies indicate that over 90% of dogs undergoing TPLO surgery regain normal limb function within a year, with sustained mobility for up to 6.8 years post-surgery. Younger dogs (under 5 years) often experience full recovery with minimal arthritis, while older dogs may develop mild stiffness but continue to lead active lives.

A long-term study on large breeds found that 76% showed no significant lameness a decade after surgery.

As Dr. David Dycus, DVM, highlights, managing weight and caring for joints are vital for the best results. He supports a patient-focused approach, stressing the importance of communication and personalized treatment plans to ensure the best quality of life for dogs.

Gait and Limb Function Studies

Long-term studies show that most dogs undergoing TPLO surgery regain almost normal gait and weight distribution within a year, with continued improvements over time. For example, research comparing TPLO to extracapsular repair found that dogs achieved normal limb loading faster after TPLO, with the operated limb functioning similarly to control groups by one year after surgery.

However, subtle changes can persist. Some dogs may slightly favor the surgical leg, especially in colder weather or after long periods of rest. A study evaluating recovery of limb function post-TPLO noted that while significant improvements were observed, certain gait changes could remain, particularly under specific conditions.

These findings suggest that while TPLO effectively restores function, individual variations in recovery and gait adaptations can occur.

Does TPLO Prevent Arthritis in the Long Run?

Arthritis is a common concern after any knee surgery. TPLO helps slow down arthritis by stabilizing the joint and reducing abnormal movement, but it doesn't completely remove the risk. Over time, most dogs develop some arthritis, but it's usually less severe than in knees that are untreated or not properly repaired.

TPLO vs. Other Procedures (TTA, Lateral Suture) for Arthritis Prevention

When comparing surgical options, TPLO has a lower rate of arthritis progression than lateral suture surgeries, which depend on external stabilization that can stretch over time. Studies show that dogs undergoing TPLO have better long-term mobility and less joint inflammation.

When comparing TTA (Tibial Tuber osity Advancement) to TPLO, research suggests similar long-term arthritis outcomes, but TPLO patients usually recover faster and regain function sooner.

No matter the procedure, managing weight, using joint supplements, and engaging in regular low-impact exercise are crucial for slowing arthritis progression.

TPLO Implant Longevity & Failure Rates

One of the main concerns with TPLO surgery is the long-term durability of the metal plate and screws used to stabilize the knee. Although TPLO is meant to be a permanent solution, implant-related issues can occur in a small number of cases.

Do TPLO Plates & Screws Last a Lifetime?

For 90–95% of dogs, TPLO implants stay intact and functional for life. The titanium or stainless steel plates are biocompatible and rarely cause problems. However, implant failure happens in 5–10% of cases, often due to:

• Screw loosening from too much activity or poor bone healing
• Irritation from cold weather or pressure on the plate
• Infection, which may develop months or years after surgery

Signs of implant failure include ongoing limping, localized swelling, or heat around the knee. If problems occur, implant removal or replacement might be needed.

Risk of TPLO on the Opposite Leg

One of the most significant long-term concerns after TPLO surgery is the risk of a cranial cruciate ligament (CCL) tear in the opposite leg. As dogs rely on their healthy leg during recovery, it often takes on more stress, which can speed up ligament wear.

What Are the Chances of Needing TPLO on the Other Leg?

Studies show that 30–50% of dogs need TPLO on the opposite leg within 2–5 years. Risk factors include:

• Obesity, which puts extra strain on joints
• High activity levels, causing wear and tear
• Poor muscle balance, affecting joint stability

To lower the risk, controlled exercise, muscle-strengthening therapy, and strict weight management are crucial. Joint supplements and physical therapy can also help maintain long-term knee health. While a second TPLO might be needed, early intervention and proper care can delay or prevent another surgery.

Long-Term Satisfaction: Are Owners Happy Years After TPLO?

For most pet owners, TPLO surgery is a valuable investment in their dog's mobility and quality of life. Years after the surgery, most report significant improvements in their pet's activity levels, with only a few long-term concerns.

What Pet Owners Say About TPLO Years Later

Studies show that 80–90% of owners are satisfied with their dog's long-term recovery. Many dogs return to running, hiking, and playing without noticeable lameness. However, some owners have concerns, particularly due to:

• Arthritis development, which is common but varies in severity
• Implant issues, such as irritation or the rare need for removal
• A second TPLO surgery, as 30–50% of dogs eventually need the procedure on the other knee

Dogs that undergo structured rehabilitation, maintain an ideal weight, and stay active with controlled exercise tend to have the best long-term results. Proper post-op care and regular vet checkups can maximize mobility and minimize complications, ensuring TPLO remains a lasting solution.

Late-onset lameness & Joint Stiffness

While TPLO provides excellent long-term outcomes, some dogs develop mild lameness or stiffness years after surgery. This can occur due to arthritis progression, muscle imbalances, or implant irritation, even in otherwise successful cases.

Why Do Some Dogs Develop Lameness Years Later?

Several factors contribute to late-onset lameness after TPLO:

• Arthritis progression: TPLO slows but doesn't stop joint degeneration. Over time, cartilage wear leads to stiffness, especially in older dogs.
• Scar tissue formation: Some dogs develop fibrotic tissue around the knee, which reduces flexibility and changes movement patterns.
• Muscle weakness from inadequate rehab: A lack of structured post-surgery rehabilitation can lead to ongoing muscle imbalances, putting strain on the joint.

Solutions for Maintaining Mobility

To reduce long-term stiffness, consistent low-impact exercise (like swimming or controlled walking) is crucial. Joint supplements (glucosamine, omega-3s) can help slow arthritis progression, and regular vet check-ups ensure early detection of any issues.

For dogs showing signs of discomfort, physical therapy and anti-inflammatory management can greatly improve their quality of life.

How Well Does TPLO Hold Up in Active & Working Dogs?

For working dogs, agility competitors, and high-energy breeds, long-term durability is a major concern after TPLO surgery. While the procedure restores knee stability, the intense physical activity these dogs engage in can increase the risk of re-injury and joint strain over time.

Can Working & Sporting Dogs Perform Well After TPLO?

Many agility, service, and hunting dogs successfully return to full activity after TPLO. A study on sporting breeds found that over 80% regained their pre-injury performance levels with proper rehabilitation. However, working dogs face a higher risk of reinjury or implant stress, especially if they resume activity too soon.

Key factors for long-term success include:

• Gradual reconditioning with structured rehab
• Hydrotherapy for low-impact muscle strengthening
• Targeted strength training to prevent imbalances

While some stiffness or mild arthritis may develop over time, most active dogs remain highly functional for 5–10+ years post-surgery with proper care. Regular joint supplements, vet check-ups, and monitored exercise can help protect their long-term mobility.

Comparing TPLO to No Surgery: Is It Worth It?

Some pet owners wonder if TPLO is truly necessary or if their dog could recover naturally. While there are non-surgical options, studies consistently show that dogs undergoing TPLO have better long-term outcomes in terms of mobility, pain management, and quality of life.

What Happens to Dogs Who Don’t Get TPLO?

Without surgery, a cranial cruciate ligament (CCL) tear leads to chronic instability, causing:

• Severe arthritis due to ongoing joint wear
• Chronic pain that worsens over time
• Progressive loss of mobility, often requiring lifelong pain management

Alternatives like bracing, physical therapy, and pain medications can provide some relief but rarely restore full function. A study comparing TPLO to non-surgical treatment found that over 90% of TPLO dogs regained normal mobility, while non-surgical cases had a much higher risk of long-term lameness and reduced activity levels.

When comparing lifespan and activity, TPLO-treated dogs remain more active for longer, often enjoying 5–10+ years of quality mobility post-surgery. For most dogs, TPLO remains the gold standard for CCL injuries.

Does TPLO Surgery Help Dogs Live Longer?

While TPLO is mainly done to restore mobility, its long-term effects can affect a dog’s overall lifespan by improving their quality of life and reducing chronic joint pain.

Longevity & Lifespan Impact

There are no direct studies showing TPLO extends lifespan, but research indicates that dogs with untreated CCL tears have higher risks of arthritis, chronic pain, and reduced activity levels—factors that can indirectly affect longevity. Chronic joint pain leads to less exercise, weight gain, and muscle loss, which may contribute to other health issues like heart disease or metabolic disorders.

In contrast, TPLO restores stable movement, allowing dogs to stay active for years. With proper weight control, joint supplements, and post-surgical rehab, TPLO-treated dogs enjoy a higher quality of life well into their senior years. While the surgery itself doesn’t guarantee a longer lifespan, it significantly improves mobility and comfort, contributing to better long-term health.

Final Thoughts

TPLO is widely seen as the gold standard for CCL injuries, providing strong, lasting mobility improvements for most dogs. Studies show that 85–90% of dogs regain near-normal function after surgery, with benefits lasting well into their senior years.

However, arthritis remains a common concern, even in successful TPLO cases. Implant-related issues, like irritation or screw loosening, happen in a small percentage of dogs (5–10%), but these can often be managed with proper care.

Dogs that undergo structured rehabilitation, maintain a healthy weight, and receive joint supplements tend to have the best long-term results. Regular vet check-ups help detect and address potential issues early.

While TPLO doesn’t eliminate every risk, it significantly improves mobility and quality of life, making it the preferred choice for long-term knee stability. Lifelong joint care is essential for maximizing success.

‍

Is Clicking Normal After TPLO Surgery?

Yes, clicking is a common sign after TPLO (Tibial Plateau Leveling Osteotomy) surgery. Many dogs experience this during the healing process. The clicking sound often happens when your dog walks, especially in the early weeks after surgery. It usually comes from the knee joint or nearby soft tissues adjusting to the new implant and bone alignment.

In most cases, the clicking is not painful or harmful. It may be due to muscle weakness, swelling, or the movement of healing tissues around the surgical site. As your dog builds strength and the joint stabilizes, the clicking often goes away on its own.

However, while it is usually harmless, clicking that gets worse or lasts longer than expected should be checked by your vet. It’s important to track any changes in your dog’s walking, behavior, or comfort level during recovery to rule out complications.

Common Reasons Behind the Clicking Sound

Several factors can cause a clicking sound in your dog’s leg after TPLO surgery. One of the most common reasons is scar tissue formation around the joint. As the tissues heal, they can tighten or shift slightly, creating a clicking noise when your dog moves.

Another reason is muscle or tendon movement over the joint. After surgery, the muscles and tendons may not glide smoothly due to inflammation or changes in joint structure. This can lead to a clicking or popping sound during certain motions.

The bone healing and remodeling process also plays a role. As the bone heals and reshapes around the implant, small adjustments happen within the joint that can produce sounds. This is usually temporary and improves as healing continues.

Sometimes, the implants—such as the plate or screws—may shift slightly or settle into position, especially in the early stages of healing. This minor movement can also cause clicking but is often not serious.

Lastly, natural joint movement itself can create a clicking noise. As your dog regains strength and mobility, the knee may make sounds during stretching, walking, or sudden turns. Most of these causes are harmless, but it's always good to consult your vet if the clicking is persistent or paired with pain.

When Should You Be Concerned?

Clicking sounds are usually harmless after TPLO surgery, but in some cases, they can point to a problem. Contact your vet if you notice any of the following:

• Clicking is new or getting louder - If the clicking sound wasn't there before or is increasing over time, it could mean something has shifted in the joint or implant.
• Swelling around the surgical site - Mild swelling early on is normal, but swelling that appears later or keeps growing may be a sign of infection or poor healing.
• Signs of pain, limping, or stiffness - If your dog starts limping again, avoids putting weight on the leg, or shows stiffness when moving, it may indicate discomfort or complications.
• Decreased activity or appetite - Dogs often hide pain, so a sudden drop in energy, playfulness, or appetite should raise concern.
• Clicking with joint instability - If the knee feels wobbly or your dog’s leg gives out when walking, this could mean the implant has loosened or the bone isn’t healing well.

In any of these cases, it’s best to have your vet check your dog’s leg to make sure the recovery is going as planned.

Could It Be a Complication?

In some cases, clicking after TPLO surgery may point to a complication. One possible cause is meniscus damage that wasn’t found or treated during surgery. The meniscus is a small piece of cartilage that cushions the knee. If it tears or becomes damaged later, it can cause pain, limping, and clicking sounds.

Another rare but serious issue is implant failure. Plates or screws can loosen, shift, or break, especially if the dog is too active too soon after surgery. This can lead to discomfort and joint noises.

Joint instability is also a concern if the bone hasn’t fully healed or if the implant isn’t holding the bone tightly. In this case, the knee may move abnormally, causing clicking or popping sounds.

Larger dogs are more likely to make joint sounds during recovery. Their extra weight puts more pressure on the healing leg, which can make clicking more noticeable. While this doesn’t always mean there’s a problem, it’s important to monitor them closely.

If the clicking is paired with pain, swelling, or limping, it’s best to have your vet check for complications and take X-rays to confirm that everything is healing as it should.

What Can Help Reduce the Clicking?

To help reduce clicking sounds after TPLO surgery, focus on proper recovery care. Here are some helpful steps:

• Limit activity and allow proper rest - Too much movement early on can cause stress on the joint. Keep your dog’s activity low during the first 8–10 weeks after surgery.
• Use physical therapy or controlled exercises - Gentle rehab movements can strengthen muscles around the joint, reduce instability, and help the leg move more smoothly. Ask your vet for a safe exercise plan.
• Give anti-inflammatory medications if prescribed - These help reduce swelling and irritation in the joint, making movement more comfortable and quiet. Only use medications approved by your vet.
• Manage your dog’s weight - Extra weight puts more stress on the healing leg, especially in large breeds. Keeping your dog at a healthy weight supports smoother recovery and fewer joint sounds.

By following these steps and staying in touch with your vet, the clicking sound usually fades over time. Most dogs heal well with rest, patience, and proper care.

What to Expect During Recovery

During recovery from TPLO surgery, it’s common to hear clicking sounds in your dog’s leg, especially in the first few weeks. In most cases, this clicking fades over time as the bone heals, muscles strengthen, and the joint stabilizes. For many dogs, the sound goes away completely within a few months.

However, some dogs may still have a soft clicking sound even after full healing. This is often not painful and doesn’t affect how they walk or play. Many dogs adapt well, and the clicking becomes less noticeable over time.

Healing timelines can vary depending on your dog’s size, age, and overall health. Larger dogs or those with other joint issues may take longer to recover. Regular follow-ups, controlled activity, and proper rest are key during this time.

Always keep an eye on any changes and check with your vet if anything feels off during recovery.

When to Visit the Vet

While clicking after TPLO surgery is often harmless, there are times when a vet visit is necessary. You should contact your vet if the clicking sound is persistent or getting worse over time. A mild clicking early in recovery is normal, but it should improve as healing progresses.

If the clicking is accompanied by other symptoms—like pain, swelling, limping, stiffness, or your dog avoiding the leg—this could signal a problem. These signs may point to joint instability, implant issues, or even a torn meniscus that needs attention.

It’s also important to follow up with your vet for scheduled post-op checks. These visits often include physical exams and sometimes X-rays to confirm that the bone is healing properly and the implant is stable. Don’t skip these checkups, even if your dog seems fine.

If you notice anything unusual, it’s always safer to have your vet take a look. Early care can prevent bigger problems later in recovery.

Conclusion

Clicking after TPLO surgery is common and usually not a cause for concern. It often happens during the healing phase and may come from scar tissue, joint movement, or muscle adjustment. In most cases, the sound fades over time as your dog regains strength and the joint stabilizes.

However, it’s important to watch for any changes. If the clicking gets louder, doesn’t go away, or comes with pain, swelling, or limping, don’t wait—contact your vet. Regular rest, controlled exercise, and follow-up visits play a big role in a smooth recovery.

Every dog heals at a different pace, and some may adapt even if mild clicking remains. With proper care and attention, most dogs return to normal activity and enjoy a pain-free life after TPLO surgery. Stay patient, stay observant, and always follow your vet’s guidance.

Tibial Plateau Leveling Osteotomy (TPLO) surgery is a common procedure used to treat a torn cranial cruciate ligament (CCL) in dogs. This ligament is crucial for stabilizing the knee joint, and when it's damaged, it can cause pain, lameness, and arthritis.

TPLO surgery is very effective in restoring mobility, but many pet owners are curious about its long-term effects. Knowing what to expect years after the surgery can help you provide better care for your dog and make informed health decisions.

In this article, we’ll discuss the potential long-term effects of TPLO surgery, including the benefits, risks, and challenges. By the end, you’ll have a clear understanding of how this surgery affects your dog’s quality of life and what you can do to help them thrive.

1. Improved Mobility and Quality of Life

One of the biggest long-term benefits of TPLO surgery is improved mobility. After recovery, most dogs regain full use of the affected leg and return to activities they enjoyed before the injury. This improvement usually lasts a long time, and many dogs stay active for years after the surgery.

If your dog has trouble walking or playing because of a torn CCL, TPLO surgery can often make a big difference. With less pain and more stability, they can move comfortably. However, it's important to keep an eye on their activity levels, as too much exertion can lead to other joint issues. You might also notice your dog slightly favoring the surgical leg less than the other one as they age, which is completely normal.

2. Risk of Arthritis in the Affected Joint

Arthritis is a common concern after TPLO surgery. While the procedure stabilizes the knee and slows down the progression of arthritis, it doesn't completely eliminate the risk. Dogs with a history of CCL tears often develop arthritis in the affected joint over time, which can lead to stiffness, discomfort, and reduced flexibility.

To reduce the impact of arthritis, it's important to manage your dog's weight, provide joint supplements like glucosamine, and ensure they get regular, low-impact exercise. Activities like swimming or gentle walks can help keep their joints healthy without putting too much stress on the repaired knee.

You can also discuss long-term pain management options with your veterinarian, such as anti-inflammatory medications or physical therapy.

3. Potential for Opposite Leg Injuries

A less-discussed long-term effect of TPLO surgery is the increased risk of a CCL tear in the opposite leg. Studies suggest that up to 50% of dogs who have had TPLO surgery on one leg may experience a similar injury on the other leg within a few years. This often happens because the opposite leg compensates for the injured one during recovery, leading to extra strain.

To reduce this risk, focus on balanced physical therapy and muscle-strengthening exercises after surgery. Keeping your dog at a healthy weight is also important, as extra weight puts more stress on the joints. If your dog does tear the other CCL, the good news is that TPLO surgery can also be performed on the second leg with similar success rates.

4. Long-Term Scar Tissue and Stiffness

Scar tissue formation is a natural part of healing after TPLO surgery. Usually, this tissue helps stabilize the joint and doesn't cause major problems. However, some dogs might feel stiff occasionally, especially in colder weather or after being inactive for a long time.

You can help reduce stiffness by keeping your dog warm in the winter and encouraging gentle movement throughout the day. Joint massages and passive range-of-motion exercises can also improve flexibility. If the stiffness continues or gets worse, consult your veterinarian to check for any complications.

5. Implant-Related Complications

During TPLO surgery, a metal plate and screws are used to stabilize the knee. These implants are meant to stay in place permanently, but in rare cases, they can cause problems. For example, some dogs may develop infections around the implant or experience loosening of the hardware over time.

Signs of implant-related issues include swelling, redness, or limping long after the surgery has healed. If you notice any of these symptoms, it’s important to have your dog checked by a veterinarian. In some cases, the implant may need to be removed, but this is uncommon when the surgery is done correctly.

6. Weight Management Challenges

As we discussed in the sections above, maintaining your dog’s ideal weight is one of the most important long-term considerations after TPLO surgery. Excess weight can strain the repaired knee and increase the risk of arthritis and other joint problems. Unfortunately, some dogs become less active during their recovery, which can lead to weight gain.

To manage this, ensure your dog has a balanced diet with controlled portions. Your veterinarian can recommend a weight management plan tailored to your dog’s needs. Regular exercise, such as swimming or short walks, can also help keep them fit without putting too much pressure on their joints.

7. Joint Mechanics and Biomechanics Over Time

After TPLO surgery, the way your dog's knee joint works changes a lot. The surgery changes the angle of the tibial plateau to stop instability, which can affect how your dog moves. Over time, these changes might lead to different posture or walking patterns.

While these adjustments are usually well-tolerated, it's important to keep an eye on your dog's movement. Any noticeable changes in walking or weight distribution should be checked by a veterinarian to catch potential issues early.

8. Age-Related Factors

Your dog's age at the time of TPLO surgery significantly affects their recovery and long-term outcomes. Younger dogs usually heal faster and regain full mobility more easily. Their bodies are more resilient, making them less likely to develop complications like arthritis or stiffness.

Older dogs, however, may heal more slowly and have a higher chance of developing age-related conditions such as arthritis or joint issues. If your dog is older, your veterinarian might suggest additional pre-surgical tests to check their overall health and customize the recovery plan.

Supplements, weight management, and ongoing physical therapy can further enhance their long-term quality of life, even if they encounter age-related challenges.

9. Infection Risks and Chronic Inflammation

Infections after TPLO surgery are rare but can happen, especially around the surgical implants. Chronic or delayed infections may cause inflammation, discomfort, and even joint instability if not treated.

However, many surgeons now use surgical lavage solutions like Simini Protect Lavage to significantly reduce the risk of infections. These advanced solutions help keep the surgical area sterile, resulting in safer outcomes.

Signs of infection include redness, swelling, warmth, or ongoing limping near the surgical site. If you see any of these symptoms, contact your veterinarian right away. Early treatment can stop infections from getting worse and help ensure a smoother recovery.

10. Ongoing Rehabilitation Needs

TPLO surgery is just the first step in your dog’s recovery. Long-term success often relies on regular rehabilitation and strengthening exercises. Physiotherapy and hydrotherapy are especially effective for improving mobility, rebuilding muscle mass, and reducing joint stiffness.

Your veterinarian might suggest a customized rehabilitation plan that includes specific exercises like sit-to-stand repetitions, controlled leash walks, or underwater treadmill sessions. These activities can help restore muscle strength and balance, ensuring your dog fully uses the affected leg.

Regular follow-ups with a canine physical therapist or vet will ensure the plan adjusts to your dog’s changing needs.

11. Nutritional Considerations for Joint Health

Nutrition is crucial for supporting your dog's joints after TPLO surgery. Veterinarians often suggest adding supplements like glucosamine, chondroitin, and omega-3 fatty acids to your dog's diet. These supplements help maintain cartilage health, improve joint lubrication, and reduce inflammation.

A balanced diet with high-quality protein is also important for rebuilding muscle and supporting overall recovery. If your dog is overweight, a weight management plan guided by a veterinarian is essential to reduce stress on the repaired knee. Always consult your vet before adding any new supplements to make sure they are suitable for your dog's specific needs.

12. Behavioral Adjustments and Anxiety

It's common for dogs to experience behavioral changes, like anxiety or reduced activity levels, after TPLO surgery. Limited mobility during recovery can cause frustration, boredom, or even depression. Dogs that were very active before may find it hard to adjust to temporary restrictions.

To keep your dog mentally engaged, try using puzzle toys, treat-dispensing games, or gentle training exercises that don't strain their knee. Spending quality time with your dog during recovery can also help reduce anxiety. If your dog shows signs of ongoing stress or behavioral changes, consult your veterinarian for advice or consider working with an animal behaviorist.

13. Genetic Predispositions

Certain breeds are genetically more prone to joint problems, which can affect their long-term outcomes after TPLO surgery. For example, large breeds like Labrador Retrievers, Golden Retrievers, and Rottweilers often have a higher risk of developing arthritis or degenerative joint issues as they age. These genetic factors can impact their recovery and increase the chance of future joint instability.

If your dog is a high-risk breed, taking preventive steps is crucial. These include keeping a healthy weight, providing joint supplements, and following a regular, low-impact exercise routine. Regular check-ups with your vet will help detect potential issues early, ensuring your dog remains active and comfortable for as long as possible.

Conclusion

That's all you need to know about the long-term effects of TPLO surgery, which include both benefits and challenges, such as improved mobility and the risk of arthritis or joint degeneration. By actively managing your dog's care—through weight control, balanced exercise, and regular vet visits—you can help them enjoy a high quality of life.

Although challenges like implant wear, muscle loss, or age-related changes may occur, ongoing care and rehabilitation can significantly help in keeping your dog happy and active for years to come.

Understanding Swelling After TPLO Surgery

Swelling is one of the most common post-surgical effects after TPLO surgery and a normal response to bone and soft-tissue manipulation. It’s part of the body’s natural repair process, helping deliver immune cells and nutrients to the surgical site. Understanding how much swelling is normal helps you track healing progress and detect problems early.

• Why Swelling Happens: During TPLO surgery, tissues are cut and repositioned around the tibia. The body reacts by sending inflammatory fluids and white blood cells to protect the area, causing temporary puffiness or firmness.
• Healing Function: Controlled inflammation aids recovery by clearing damaged cells and promoting tissue repair. It’s a key part of early bone healing in orthopedic surgeries.
• Types of Swelling: Mild swelling looks soft and reduces within a week with rest and cold compresses. Moderate swelling may cause mild warmth or stiffness but remains non-painful. Severe swelling, redness, or oozing signals infection or internal bleeding and needs urgent veterinary evaluation.

Recognizing normal versus abnormal swelling ensures timely intervention and supports a smoother, safer recovery after TPLO surgery.

Normal Timeline: How Long Swelling Lasts After TPLO Surgery

Mild to moderate swelling is expected after TPLO surgery, as the body responds to tissue trauma and healing begins. Understanding the normal timeline helps you distinguish healthy inflammation from potential complications.

• Typical Duration: Most dogs experience visible swelling for 3–7 days after surgery, peaking around day two or three. It gradually decreases as tissues start healing.
• Improvement Signs: Swelling should reduce noticeably by the end of the first week, with the incision area looking less puffy and the leg regaining flexibility.
• Extended Swelling Causes: Persistent swelling beyond a week may occur if the dog is overactive, licks the incision, or experiences friction from bandages.
• Influencing Factors: Large breeds, older dogs, or those with delayed healing may show prolonged swelling, especially without adequate rest.
• Monitoring Daily: Measuring or photographing the incision area helps track recovery progress and detect abnormal changes early.

As a general rule, swelling should lessen steadily each day. Any worsening or lack of improvement after one week warrants a call to your veterinarian.

What Normal Post-Operative Swelling Looks Like

Recognizing what healthy swelling looks like helps prevent unnecessary concern during your dog’s recovery. Normal post-operative inflammation is mild, symmetrical, and typically improves with basic care.

• Mild Puffiness: A soft, localized swelling around the knee joint or incision area is expected. The tissue may feel slightly firm but not painful when gently touched.
• Slight Warmth and Color Change: A light pink tone and mild warmth indicate good blood flow supporting healing. It should not feel hot or tender.
• Visible Improvement: Swelling starts to subside within several days as fluid drains naturally through the lymphatic system.
• Effect on Movement: Dogs may walk stiffly or limp slightly due to mild discomfort but should still bear some weight on the leg.
• Response to Care: Cold compresses, prescribed anti-inflammatory medication, and controlled rest help visible improvement appear within a week.

These mild signs of swelling represent the body’s healthy inflammatory phase and are an important part of tissue repair after TPLO surgery.

When Swelling Becomes a Concern After TPLO Surgery

While some inflammation is normal, excessive or worsening swelling can signal infection, seroma formation, or implant-related problems. Recognizing warning signs early is critical to prevent complications.

• Heat and Redness: If the surgical area feels hot, reddened, or painful to touch, infection or deeper inflammation may be developing.
• Discharge or Odor: Fluid leakage, pus, or foul smell from the incision suggests bacterial contamination that requires immediate veterinary care.
• Swelling Spreading Up the Leg: Puffy tissue moving toward the thigh or ankle indicates fluid buildup (seroma) or poor lymph drainage.
• Pain and Reluctance to Move: If your dog avoids using the leg, vocalizes when touched, or becomes lethargic, inflammation may be extending beyond normal levels.
• Fever or Appetite Loss: Systemic infection signs, such as fever or lack of appetite, mean urgent medical attention is needed.

Contact your veterinarian immediately if swelling increases after the first week or if any of these red flags appear. Prompt treatment prevents serious post-surgical complications.

Factors That Affect How Long Swelling Lasts After TPLO Surgery

Every dog heals differently, and several factors determine how long swelling persists after TPLO surgery. Paying attention to these variables helps guide proper recovery management.

• Dog’s Size and Age: Larger and older dogs often experience longer healing periods because their tissues repair more slowly.
• Surgical Technique: Advanced surgical precision and proper implant placement reduce post-operative trauma and minimize inflammation duration.
• Implant Type: Stainless steel or titanium plates can influence swelling based on how the body responds to foreign materials.
• Post-Surgery Care: Following activity restrictions, preventing licking, and maintaining crate rest are crucial for controlling inflammation.
• Use of Medication: Anti-inflammatory drugs and prescribed cold therapy shorten swelling duration by controlling tissue fluid buildup.
• Underlying Health: Dogs with obesity, arthritis, or poor circulation tend to show delayed recovery and prolonged swelling.

By understanding these factors, owners can set realistic expectations and work with their vet to customize an effective recovery plan.

How to Reduce Swelling After TPLO Surgery

Proper aftercare plays a key role in controlling swelling and supporting bone healing. Consistent management helps reduce discomfort and speeds recovery.

• Cold Compress Therapy: Apply a cold pack wrapped in a towel for 10–15 minutes every few hours during the first 48 hours to limit inflammation.
• Rest and Confinement: Restrict activity with crate rest or limited movement to prevent fluid accumulation or incision strain.
• Medication Adherence: Use prescribed pain relievers and anti-inflammatory drugs exactly as directed to control swelling from within.
• Incision Protection: Prevent licking or scratching by using an e-collar or surgical suit to keep the wound clean.
• Monitor Bandages: Ensure wraps aren’t too tight, as restricted blood flow can worsen swelling instead of helping it.

With consistent rest, medication, and monitoring, most swelling resolves smoothly, supporting a faster and more comfortable TPLO recovery.

Role of Physical Therapy in Managing Swelling After TPLO Surgery

Physical therapy is an important part of recovery after TPLO surgery, helping to restore mobility and prevent fluid buildup once the incision has healed.

• Timing of Rehabilitation: Gentle range-of-motion exercises usually begin 2–3 weeks post-surgery after your vet confirms bone stability.
• Improving Circulation: Controlled movement promotes lymphatic drainage, reducing swelling while maintaining joint flexibility.
• Muscle Strength Preservation: Gradual exercises prevent muscle loss and stiffness caused by extended rest periods.
• Hydrotherapy Benefits: Water-based therapy supports weightless exercise, improving motion without putting strain on the operated leg.
• Professional Guidance: Rehabilitation should always be supervised by your vet or a certified rehab specialist to prevent overexertion.

Properly timed and guided therapy significantly improves comfort and reduces lingering swelling, ensuring a stronger, more balanced recovery.

When Swelling Reappears Weeks After TPLO Surgery

If swelling returns weeks after TPLO surgery, it often points to secondary issues rather than normal healing. Identifying the cause early ensures timely intervention.

• Implant Irritation: Metal plates or screws can sometimes irritate nearby tissues, especially if the dog resumes activity too soon.
• Overuse or Early Exercise: Premature running, jumping, or playing can trigger soft tissue inflammation and localized swelling.
• Seroma Formation: Fluid pockets under the incision may develop if tissue healing is incomplete or disrupted.
• Infection Recurrence: Bacterial contamination can cause delayed redness, discharge, and swelling weeks after surgery.
• Follow-Up X-Rays: Imaging helps confirm implant stability and bone healing progress if swelling persists unexpectedly.

Recurrent swelling is not typical and requires prompt veterinary assessment to rule out infection, hardware complications, or incomplete bone union.

Conclusion

Swelling after TPLO surgery is normal, but its duration and appearance offer important clues about healing progress. Mild swelling should begin to fade within a week, while redness, heat, or discharge require prompt veterinary attention.

• Normal vs. Abnormal: Healthy swelling is mild, localized, and improves daily; worsening inflammation signals complications.
• Daily Monitoring: Check the incision site every day for color, warmth, or texture changes to catch issues early.
• Vet Check-Ups: Scheduled follow-ups and post-operative imaging confirm bone healing and implant stability.

By staying observant and following your vet’s care instructions, you can ensure swelling resolves safely and your dog recovers comfortably after TPLO surgery.

FAQs

How long should I expect swelling to last after TPLO?

Most swelling lasts between 3 and 7 days after TPLO surgery. It usually peaks within the first 48 hours, then gradually subsides as healing progresses. If swelling persists beyond a week or worsens instead of improving, contact your veterinarian for an examination to rule out infection or fluid buildup.

Is it normal for swelling to get worse at night?

Yes, mild nighttime swelling can occur because your dog moves less while resting, allowing fluids to settle around the surgical site. This should improve by morning or after gentle repositioning. Persistent or painful swelling overnight, however, may indicate inflammation that needs veterinary evaluation.

Can cold compresses help reduce swelling faster?

Cold therapy is highly effective in the first 48 hours after TPLO surgery. Applying a cold compress wrapped in a soft cloth for 10–15 minutes several times daily helps minimize fluid buildup and reduce pain. Always avoid direct ice contact with the incision area to prevent skin irritation.

When should I worry about swelling or redness?

You should be concerned if swelling increases after the first week or is accompanied by heat, redness, oozing, or a bad odor. These may signal infection, seroma, or implant irritation. Immediate veterinary assessment ensures early treatment and prevents more serious complications.

What if my dog starts limping again weeks later?

Limping weeks after surgery may suggest muscle overuse, implant irritation, or delayed healing. Recurring swelling along with limping can indicate inflammation or hardware issues. Schedule a follow-up appointment and, if needed, X-rays to confirm proper bone healing and plate stability.

What Is TPLO Surgery and Why Dogs Need It

TPLO (Tibial Plateau Leveling Osteotomy) is a surgical procedure used to treat cranial cruciate ligament (CCL) injuries in dogs. The CCL is one of the key ligaments that stabilizes the knee joint. When it tears—often due to sudden movement or long-term wear—your dog may limp, avoid putting weight on the leg, or show signs of pain and stiffness.

Instead of repairing the torn ligament directly, TPLO works by changing the angle of the tibia (shin bone). This helps stop the femur from sliding forward, restoring stability to the knee. Once the bone is cut, rotated, and secured with a metal plate, your dog can start healing.

TPLO is one of the most effective surgeries for dogs with CCL injuries. It helps reduce pain, improve mobility, and supports long-term joint function, especially in active or large-breed dogs.

Early Signs You Might Miss

CCL injuries often start with small changes in your dog’s behavior. These signs are easy to overlook but may point to early joint pain or instability. Keep an eye out for the following:

• Reduced activity levels or sudden laziness - Your dog may seem more tired than usual, sleep more, or lose interest in walks. This drop in energy could be due to discomfort in the knee.
• Unwillingness to play or move as usual - Dogs with early joint pain may avoid games, running, or exploring. If your dog used to be active and suddenly seems withdrawn, it’s a sign something may be wrong.
• Reluctance to jump, run, or climb stairs - Pain in the knee joint can make jumping or climbing uncomfortable. Hesitating at stairs or avoiding furniture are common signs of a CCL issue.

Noticing these subtle changes early can help you get the right care before the injury worsens.

Moderate Signs That Show Joint Discomfort

As a CCL injury progresses, your dog may begin to show more noticeable signs of discomfort. These signs often appear during movement or rest and are easier to spot than early-stage symptoms. Here’s what to look for:

• Awkward sitting posture - Dogs with knee pain often sit with one leg stretched out to the side instead of tucking it under their body. This helps avoid pressure on the sore joint.
• Stiffness and pain in the hind legs, especially after rest - After lying down for a while, your dog may struggle to get up or walk stiffly for the first few steps. This stiffness often improves with movement but returns after rest.
• Occasional limping - Limping may come and go, especially after exercise or long walks. Some days may seem better than others, but this inconsistency is a sign of joint problems.
• “Toe-touching” gait - Your dog may lightly place just the toes of the affected leg on the ground while walking, without putting full weight on it. This is a common sign of knee pain.

These symptoms show that the joint is under stress and may need medical attention.

Advanced Signs That May Require Surgery

When a cranial cruciate ligament (CCL) is fully torn or severely damaged, the signs become more serious and harder to ignore. These advanced symptoms often mean the joint is unstable and surgery like TPLO may be needed for proper healing. Watch for the following:

• Partial weight-bearing on one hind leg - Your dog may keep most of their weight off one back leg, only touching it to the ground when necessary. This helps them avoid pain from an unstable knee.
• Persistent lameness or limping after rest - Unlike earlier stages, the limping doesn’t improve with movement. Your dog may continue to favor the leg all day, especially after sleeping or lying down.
• Difficulty rising or sitting - Getting up becomes slow and painful. Your dog may shift their weight awkwardly or need help standing.
• Clicking or popping sounds in the knee - These noises can come from joint instability or meniscus damage and usually mean the knee is not functioning properly.
• Swelling around the knee joint - The area may look puffy or feel warm to the touch. This can be a sign of inflammation or joint damage.
• Muscle atrophy in one leg - You may notice that one thigh appears smaller than the other. This happens when the leg isn’t being used normally over time.

These signs should be evaluated by your vet to decide if surgery is the best option.

When to Visit the Vet

If your dog shows signs like limping, stiffness, difficulty rising, or toe-touching the ground, it’s time to visit the vet. Sudden changes in activity, pain, or leg use shouldn’t be ignored, especially if symptoms don’t improve within a few days. Early treatment can prevent further damage and lead to better recovery.

During the exam, your vet will check your dog’s leg for swelling, pain, range of motion, and joint stability. They may perform a drawer test to assess ligament damage. In some cases, sedation and X-rays are needed to rule out bone issues or confirm a torn cranial cruciate ligament (CCL).

Your vet will then discuss treatment options, which may include rest, medication, or surgery depending on the injury’s severity. Getting the right diagnosis early can make a big difference in your dog’s comfort and long-term mobility.

Conclusion

CCL injuries in dogs can start with small, subtle signs like reduced play or a change in posture. As the damage worsens, symptoms like limping, stiffness, or toe-touching become more noticeable. In advanced stages, your dog may avoid using one leg, show swelling, or develop muscle loss—all signs that may need surgery.

The good news is that early action can prevent long-term joint damage. Watching for behavior changes and getting a prompt vet check can lead to faster healing and better results. Even if the clicking sound or limp seems mild, it’s always worth asking your vet for advice.

TPLO surgery is often very successful in restoring mobility and comfort. With proper care and follow-up, most dogs return to their normal, active lives. Trust your instincts—if something feels off with your dog’s leg, take action early. It can make all the difference in their recovery.

FAQs

What is the most common sign that a dog needs TPLO surgery?

The most common sign is consistent limping in one of the hind legs, especially after activity or rest. Many dogs also show signs like toe-touching, stiffness, or reluctance to jump or run. These signs often point to a torn cranial cruciate ligament (CCL), which TPLO surgery helps correct.

Can these signs appear suddenly or slowly over time?

Yes, the signs can appear either way. Some dogs show sudden limping after running or jumping, while others develop symptoms gradually. You might first notice reduced activity, hesitation on stairs, or an unusual sitting posture. Both sudden and slow changes can indicate joint problems and should be checked by a vet.

Is limping always a sign of CCL injury?

Not always. Limping can be caused by many things, including sprains, muscle strains, arthritis, or paw injuries. However, long-lasting or recurring limping—especially in large or active dogs—often suggests a CCL tear. A vet exam is the best way to find the exact cause and rule out other issues.

How is a CCL tear diagnosed by a vet?

A vet will perform a physical exam to check joint stability and pain. They may use the "drawer test" or "tibial thrust test" to detect instability. Sedation is sometimes needed for accuracy. X-rays help rule out fractures and confirm swelling or arthritis linked to CCL injuries.

What happens if I delay TPLO surgery?

Delaying TPLO surgery can lead to more joint damage, increased pain, and worsening lameness. The longer the knee stays unstable, the higher the risk of meniscus injury and arthritis. Early surgery gives your dog the best chance for a full recovery and helps prevent long-term complications.
