Lameness after TPLO surgery in dogs is a common concern for pet owners. TPLO, or Tibial Plateau Leveling Osteotomy, is a surgical procedure to stabilize the knee after a cranial cruciate ligament rupture. Sometimes, dogs show limping or difficulty walking after this surgery, which can worry owners.

This article explains why lameness happens after TPLO surgery, how veterinarians diagnose it, and what treatments help dogs recover. You will learn what signs to watch for and how to support your dog’s healing process effectively.

What causes lameness after TPLO surgery in dogs?

Lameness after TPLO surgery can arise from several factors. Understanding these causes helps you recognize if your dog’s limping is normal or needs veterinary attention. Some causes are related to surgery recovery, while others may indicate complications.

• Postoperative pain: Pain from surgery and inflammation can cause limping during the first weeks, which usually improves with pain management and rest.
• Soft tissue swelling: Swelling around the knee joint after surgery can limit movement and cause discomfort, leading to temporary lameness.
• Implant irritation: The metal plate and screws used in TPLO can sometimes irritate surrounding tissues, causing discomfort and limping.
• Infection risk: Surgical site infections can cause pain, swelling, and lameness, requiring prompt veterinary care.

Other causes include meniscal injury, implant failure, or improper bone healing. Monitoring your dog closely after surgery helps detect these issues early.

How do veterinarians diagnose lameness after TPLO surgery?

Diagnosing the cause of lameness after TPLO involves a thorough physical exam and diagnostic tests. Your veterinarian will assess your dog’s gait, pain level, and surgical site condition.

• Physical examination: Checking the operated leg for swelling, heat, pain, and range of motion helps identify inflammation or injury.
• Gait analysis: Observing how your dog walks or stands can reveal the severity and pattern of lameness.
• Radiographs (X-rays): X-rays evaluate bone healing, implant position, and detect complications like fractures or loosening.
• Joint fluid analysis: In some cases, sampling joint fluid helps detect infection or inflammation inside the knee.

These diagnostic steps guide the veterinarian in choosing the best treatment plan for your dog’s recovery.

What treatments help dogs with lameness after TPLO surgery?

Treatment depends on the cause and severity of lameness. Most dogs improve with conservative care, but some need additional interventions.

• Pain management: Using prescribed pain medications and anti-inflammatories reduces discomfort and supports healing.
• Restricted activity: Limiting running, jumping, and rough play during recovery prevents stress on the surgical site.
• Physical therapy: Controlled exercises and rehabilitation improve muscle strength and joint mobility, aiding recovery.
• Surgical revision: In cases of implant failure, infection, or meniscal injury, additional surgery may be necessary to correct problems.

Following your veterinarian’s instructions closely ensures the best outcome for your dog’s lameness after TPLO surgery.

When is lameness after TPLO surgery normal versus a concern?

Some lameness is expected after TPLO surgery, especially in the first few weeks. However, persistent or worsening limping needs evaluation.

• Normal recovery lameness: Mild limping that improves gradually over 6 to 12 weeks with rest and medication is typical.
• Warning signs: Increasing pain, swelling, heat, or inability to bear weight on the leg indicates complications.
• Delayed healing: If lameness does not improve after 3 months, further diagnostics are needed to check bone healing.
• Infection symptoms: Fever, discharge from the surgical site, or foul odor require urgent veterinary attention.

Early communication with your veterinarian helps address concerns and prevents long-term problems.

How can you support your dog’s recovery after TPLO surgery?

Supporting your dog’s recovery involves careful home care and following veterinary advice. Your role is vital to reduce lameness and promote healing.

• Follow medication schedule: Administer all prescribed painkillers and antibiotics exactly as directed to control pain and prevent infection.
• Limit exercise: Keep your dog confined to a small area and avoid stairs or slippery floors to protect the surgical site.
• Use supportive devices: Consider harnesses or slings to help your dog walk safely during early recovery stages.
• Attend follow-ups: Regular veterinary visits allow monitoring of healing progress and timely intervention if needed.

Patience and consistency in care improve your dog’s comfort and speed recovery after TPLO surgery.

What are the long-term outcomes for dogs with lameness after TPLO surgery?

Most dogs regain good function after TPLO surgery despite initial lameness. Long-term success depends on proper healing and rehabilitation.

• Improved mobility: Successful TPLO surgery stabilizes the knee, allowing dogs to return to normal activity levels over time.
• Arthritis risk: Some dogs develop arthritis in the operated joint, which may cause mild chronic lameness later.
• Rehabilitation benefits: Physical therapy improves muscle strength and joint health, reducing long-term lameness risks.
• Owner vigilance: Monitoring for new limping or pain helps catch problems early and maintain quality of life.

With proper care, dogs can enjoy active lives after recovering from lameness post-TPLO surgery.

What Is Bilateral TPLO Surgery?

Tibial Plateau Leveling Osteotomy (TPLO) is a surgical procedure used to treat cranial cruciate ligament (CCL) rupture in dogs. Instead of replacing the torn ligament, TPLO alters the tibial plateau angle, stabilizing the knee joint and reducing abnormal movement.

Bilateral TPLO surgery is performed when both knees require correction. Some dogs suffer CCL injuries in both hind limbs, either simultaneously or within a short period. In such cases, a surgeon may recommend performing TPLO on both knees in a single procedure or as staged surgeries.

Large, active breeds like Labrador Retrievers, Rottweilers, Golden Retrievers, and German Shepherds are more prone to CCL injuries due to their size and activity level. Obesity, genetics, and structural predisposition also contribute to ligament degeneration, making bilateral TPLO necessary for some dogs. Early intervention helps restore mobility and prevent long-term joint damage.

When Is Double or Bilateral TPLO Surgery Necessary?

Some dogs develop cranial cruciate ligament (CCL) injuries in both knees, either at the same time or within a few months. This often occurs due to genetic factors, excessive strain on the healthy limb after an initial injury, or progressive ligament wear in both knees. When both knees are unstable, bilateral TPLO surgery is necessary to restore mobility and prevent further joint damage.

Dogs needing bilateral TPLO often show signs like severe limping, difficulty standing up, reluctance to walk or play, and an unusual sitting posture. They may shift their weight excessively, struggling to support themselves on either leg.

Veterinarians determine the need for bilateral TPLO through a detailed orthopedic exam, gait analysis, and imaging tests like X-rays. If both knees are significantly unstable, vets may recommend simultaneous TPLO to correct both knees in one procedure.

However, for older dogs or those with other health issues, a staged approach—operating on one leg first and the other after recovery—may be safer to reduce surgical risks.

Simultaneous vs. Staged TPLO Surgery: What’s the Best Choice?

When a dog needs TPLO on both knees, veterinarians consider two approaches: simultaneous TPLO (operating on both legs at once) or staged TPLO (operating on one leg first and the other after recovery).

Simultaneous TPLO

Simultaneous TPLO offers the advantage of a single anesthesia event and a shorter overall recovery period. Dogs regain balanced mobility faster since both knees heal together.

However, post-surgical care is more challenging because the dog cannot rely on a strong leg for support, requiring owners to provide intensive assistance. Risks include increased surgical stress and a higher chance of post-operative complications like swelling or infection.

Staged TPLO

Staged TPLO involves operating on one knee first, allowing recovery before addressing the second leg. This approach reduces surgical risk, making it ideal for older dogs, those with other health issues, or those struggling with post-surgical pain. However, the overall treatment period is longer, and the dog may continue to experience discomfort in the untreated leg during the recovery phase.

Veterinarians decide the best approach based on factors like the dog’s overall health, weight, pain tolerance, and the owner’s ability to manage post-surgical care.

Large dogs with strong front limbs may handle simultaneous TPLO better, while smaller or weaker dogs may benefit from a staged approach.

Benefits of Doing Bilateral TPLO Surgery at Once

For dogs needing TPLO on both knees, opting for simultaneous bilateral TPLO surgery has several advantages compared to staging the procedures months apart.

• One major benefit is a faster overall recovery period. When both knees are corrected in a single surgery, the dog undergoes just one healing phase rather than two separate ones. This means they can return to normal activity sooner compared to waiting for two rounds of surgery and rehabilitation.
• Another advantage is lower long-term costs. While simultaneous TPLO may have a higher upfront expense, it often reduces overall costs by avoiding duplicate anesthesia, hospitalization, and post-operative care fees associated with two separate surgeries. Pet owners also save on pain medications and follow-up appointments.
• Bilateral TPLO also helps prevent excessive strain on the unoperated leg. When only one knee is repaired first, the dog must rely heavily on the untreated leg, which can worsen ligament damage or lead to muscle imbalances. Simultaneous TPLO eliminates this risk by addressing both knees at once, ensuring balanced weight distribution during recovery.
• Lastly, dogs who undergo bilateral TPLO often experience better mobility post-recovery. When both knees heal together, they regain strength and stability more evenly, allowing for a smoother transition back to normal activities. This approach minimizes long-term joint issues and improves overall quality of life.

For young, healthy, and active dogs, bilateral TPLO surgery can be the best option for a quicker and more effective recovery.

How Double TPLO Surgery Is Performed

Step 1: Pre-Surgery Preparation

Before bilateral TPLO surgery, veterinarians perform a thorough evaluation, including X-rays to assess the tibial plateau angle and confirm the need for surgery.

Bloodwork ensures the dog is healthy enough for anesthesia. The dog is then sedated, intubated, and placed under general anesthesia. The surgical area on both knees is shaved and disinfected to minimize infection risk.

Step 2: Surgical Process

During the procedure, the surgeon makes an incision over each knee to access the tibia. A specialized oscillating saw is used to cut and rotate the tibial plateau, adjusting its angle to stabilize the joint and eliminate abnormal motion caused by cranial cruciate ligament (CCL) rupture. Once repositioned, a metal plate and screws are secured to hold the bone in place, ensuring proper healing and function.

To reduce the risk of biofilm formation and post-surgical infections, many surgeons use advanced solutions like Simini Protect Lavage. This non-antibiotic lavage solution helps flush out bacteria and prevent biofilm development, significantly lowering the chances of infection and promoting a safer recovery.

Combined with sterile surgical techniques and post-operative antibiotics, these measures enhance healing outcomes and minimize complications.

Step 3: Post-Surgical Stabilization and Suturing

Once both knees are stabilized, the surgeon checks for proper alignment. Soft tissues and muscles are carefully repositioned before closing the incision with sutures or staples. A sterile bandage may be applied to protect the area.

Step 4: Immediate Post-Op Monitoring at the Vet Clinic

After surgery, the dog is moved to recovery and closely monitored for pain, bleeding, or complications. Pain medications and antibiotics are administered, and vets ensure the dog is stable before planning the transition home. Owners receive detailed post-op care instructions for managing pain, mobility, and incision care.

Risks and Potential Complications of Double TPLO Surgery

While bilateral TPLO surgery is highly effective, it comes with risks and potential complications that pet owners should be aware of.

• One significant concern is the risk of infection, which can occur at the surgical site or internally around the implants. Infection risk is minimized by using sterile surgical techniques, prescribing antibiotics, and ensuring proper at-home wound care. Keeping the incision site clean and preventing the dog from licking or biting the sutures is essential for avoiding post-operative infections.
• Another risk is delayed healing, as both legs are recovering at the same time. Unlike a staged TPLO, where the healthy leg supports weight during recovery, dogs undergoing bilateral TPLO may struggle with mobility. Strict activity restrictions, proper pain management, and joint-supporting supplements can help promote faster healing.
• Implant failure or loosening is another complication that may arise, especially in highly active dogs or those with improper post-op care. Excessive movement or jumping can put stress on the surgical plates and screws, potentially leading to implant shifting or breakage. This can require additional surgery to correct.
• Lastly, anesthesia-related risks and post-operative pain are concerns with any major surgery. Though modern anesthetics are generally safe, dogs with underlying health conditions may face complications. Post-op pain is managed with medications, but owners must monitor for signs of discomfort, swelling, or limping.

Following the vet’s post-op care instructions, including strict rest and controlled rehabilitation, significantly reduces these risks and ensures a smoother recovery.

What to Expect After Double TPLO Surgery

First 24–48 Hours: Managing Pain, Limited Movement

Immediately after surgery, your dog will experience grogginess from anesthesia and discomfort from the procedure. Pain management is crucial, with vets prescribing anti-inflammatory medications and opioids for relief.

Movement should be extremely limited, and your dog may need assistance standing or going outside for bathroom breaks. Using a harness or sling can help support their weight. Swelling around the incisions is normal, but excessive redness, oozing, or heat could indicate infection.

First 2 Weeks: Strict Rest, Keeping the Dog Confined

During this period, strict crate rest or confinement in a small, quiet space is essential. Jumping, running, or sudden movements should be avoided to prevent stress on the healing bones.

Short, controlled leash walks for bathroom breaks are allowed, but no excessive movement. The surgical site should be monitored daily for any signs of infection or swelling.

Weeks 3–6: Gradual Improvement, Light Movement

By the third week, mild weight-bearing on both legs should improve, but full activity is still restricted. Short, controlled leash walks (5-10 minutes) may be introduced if the vet approves. Most dogs begin regaining stability, but muscle weakness is common.

Weeks 6–12: Rehab Starts, Monitoring for Complications

With vet approval, rehabilitation exercises such as slow leash walks, underwater treadmill therapy, or passive range-of-motion exercises can begin. Any signs of excessive limping, pain, or swelling should be reported to the vet immediately.

Full Recovery Timeline: When the Dog Can Walk, Run, and Return to Normal

By 12–16 weeks, most dogs can walk comfortably, and by 4–6 months, they regain full mobility, including running and playing. However, high-impact activities should be reintroduced cautiously under veterinary guidance to prevent re-injury.

Pain Management and Medications After Surgery

Managing pain effectively after bilateral TPLO surgery is crucial for a smooth recovery. Veterinarians typically prescribe a combination of NSAIDs (non-steroidal anti-inflammatory drugs), opioids, and supplements to control pain and inflammation.

• NSAIDs (e.g., Carprofen, Meloxicam) help reduce inflammation and swelling. These should always be given with food to prevent stomach irritation.
• Opioids (e.g., Tramadol, Buprenorphine) provide stronger pain relief in the first few days post-surgery, especially when discomfort is severe.
• Joint supplements (e.g., glucosamine, chondroitin, omega-3 fatty acids) support long-term joint health and aid in recovery.

To manage swelling and discomfort, cold therapy (icing the surgical area for 10–15 minutes, 2–3 times a day) can help reduce inflammation. Anti-inflammatory treatments, including prescribed medications and natural supplements, may further support healing.

It’s important to monitor for signs of excessive pain, such as persistent whining, heavy panting, restlessness, refusal to move, or loss of appetite. If your dog shows these symptoms despite medication, or if swelling and redness worsen, contact your vet immediately. Proper pain management not only ensures comfort but also promotes faster recovery and prevents complications.

Importance of Physical Therapy and Rehabilitation

Physical therapy plays a critical role in speeding up healing and restoring mobility after bilateral TPLO surgery. Without proper rehabilitation, dogs may experience muscle atrophy, stiffness, or prolonged discomfort.

Controlled movement helps strengthen the muscles around the knee joints, improves flexibility, and ensures a smoother recovery.

Recommended Rehab Exercises:

• Passive stretching – Gentle range-of-motion exercises help prevent stiffness and improve flexibility. These should be done 2–3 times daily with slow, controlled movements.
• Water therapy (underwater treadmill or swimming) – This is an excellent low-impact exercise that builds strength while reducing stress on the joints. Typically introduced 4–6 weeks post-surgery, if approved by the vet.
• Controlled leash walks – Short, slow walks (starting at 5 minutes per session) encourage weight-bearing and muscle engagement. Walk duration is gradually increased over time.

When to Start Rehab and Frequency:

Most rehab exercises begin around 2–3 weeks post-surgery, depending on the dog’s progress. Sessions should be daily but short to avoid fatigue. A structured rehabilitation plan, guided by a veterinarian or certified canine rehab therapist, ensures the safest and most effective recovery. Proper rehab improves strength, reduces re-injury risks, and helps dogs regain full mobility faster.

Home Care and Activity Restrictions for Recovery

Creating a safe and controlled recovery space is essential after bilateral TPLO surgery. A quiet, confined area with non-slip flooring, soft bedding, and limited space to move helps prevent accidental injuries. Using a crate or a small enclosed area with baby gates ensures your dog stays in a controlled environment while healing.

Restricting movement is crucial in the first 8–12 weeks. Jumping, running, or climbing stairs must be avoided, as sudden movements can put stress on healing bones and implants. Furniture should be blocked off, and leash walks should be strictly supervised.

For mobility assistance, supportive slings or harnesses (such as a rear-lift harness) help dogs stand up, walk for bathroom breaks, and shift weight safely. This is particularly important in the first few weeks when both legs are weak.

Since physical activity is limited, mental stimulation is key to preventing boredom and restlessness. Provide interactive toys, puzzle feeders, and scent-based games to keep your dog engaged without physical strain.

Spending extra time with your dog through gentle petting and calm interaction helps keep them relaxed and comfortable throughout recovery. Careful management ensures a smoother healing process and reduces complications.

Cost of Double or Bilateral TPLO Surgery and Financial Considerations

The cost of bilateral TPLO surgery varies depending on location, veterinary expertise, and hospital fees. In the U.S., the average cost for a single TPLO ranges from $3,500 to $6,000 per knee, meaning bilateral TPLO can cost $7,000 to $12,000. In other regions, such as Canada, the U.K., or Australia, prices may be slightly lower or higher based on veterinary costs and currency differences.

Factors affecting cost include:

• Geographic location – Urban areas with higher living costs tend to have more expensive veterinary services.
• Veterinarian experience – Board-certified surgeons may charge higher fees due to their expertise.
• Hospital fees – Costs for anesthesia, post-op care, medications, and follow-up visits add to the total.

Does pet insurance cover TPLO surgery? Coverage depends on the policy. Many comprehensive pet insurance plans cover TPLO if it’s not a pre-existing condition. Some require a waiting period before covering ligament injuries.

Financing options include payment plans through veterinary clinics, CareCredit, Scratchpay, or pet-specific credit programs to help spread out the cost. Some non-profits and crowdfunding platforms also assist pet owners facing high medical expenses.

FAQs

Can a dog have TPLO surgery on both legs?

Yes, a dog can undergo bilateral TPLO surgery if both cranial cruciate ligaments (CCLs) are torn or unstable. This can be done simultaneously or in a staged approach. Simultaneous TPLO addresses both knees in one procedure, while staged TPLO repairs one knee first, followed by the second after recovery. The choice depends on the dog’s health and the surgeon’s recommendation.

How much does bilateral TPLO surgery cost?

The cost of bilateral TPLO surgery varies by location and veterinary clinic. In the U.S., it typically ranges from $7,000 to $12,000 for both knees. Factors such as surgeon expertise, hospital fees, medications, and follow-up care affect the final price. Some pet insurance policies may cover TPLO if it is not a pre-existing condition, and financing options are available at many clinics.

What is the recovery time for bilateral TPLO surgery in dogs?

Full recovery from bilateral TPLO surgery typically takes 12 to 16 weeks. In the first 2 weeks, strict rest and pain management are essential. By weeks 3 to 6, controlled movement starts. Around weeks 6 to 12, rehab exercises begin, gradually improving strength. Most dogs return to normal activity by 4 to 6 months, but high-impact activities should be reintroduced cautiously.

What is bilateral TPLO?

Bilateral TPLO refers to Tibial Plateau Leveling Osteotomy surgery performed on both knees to treat cranial cruciate ligament (CCL) tears. It stabilizes the knee joint by altering the tibial plateau angle, preventing excessive movement. This procedure is common in large, active dogs or those genetically prone to CCL injuries. It can be done simultaneously or in two separate surgeries.

What happens if a dog tears both CCLs?

If a dog tears both cranial cruciate ligaments (CCLs), it may experience severe pain, difficulty standing, and an unstable gait. Without surgery, arthritis and joint degeneration can develop quickly. Treatment options include bilateral TPLO surgery, custom knee braces, weight management, and physical therapy. Surgery is typically the best option for restoring long-term mobility and preventing further joint damage.

‍

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.

Why Keeping Your Dog Calm After TPLO Surgery Is So Important

After TPLO surgery, keeping your dog calm is one of the most critical parts of recovery. The bone, plate, and screws need several weeks to heal securely, and any sudden movement or overactivity can disrupt that process. Rest allows tissues to rebuild and the surgical site to stabilize without extra strain.

• Prevents Implant Failure: The metal plate and screws hold the bone in position during healing. Jumping or running too early can loosen or shift these implants, leading to painful setbacks or revision surgery.
• Reduces Swelling and Inflammation: Controlled rest limits joint stress and prevents excess fluid buildup that delays bone fusion.
• Supports Safe Bone Healing: The tibia needs time for callus formation and proper alignment. Calm, limited movement ensures consistent recovery.
• Avoids Reinjury: Dogs often feel better before the bone fully heals, making them eager to move. Restricting activity keeps them from damaging soft tissue or undoing surgical repairs.
• Promotes Mental Stability: A calm environment lowers stress hormones, which supports both physical and emotional healing.

Maintaining your dog’s calm behavior after TPLO surgery is not just about obedience — it’s about protecting the repair and ensuring a smooth, complication-free recovery.

How Long Dogs Need to Stay Calm After TPLO Surgery

The healing process after TPLO surgery requires strict control of movement. Dogs typically need 6–8 weeks of restricted activity before returning to light exercise, though this can vary depending on size, age, and overall health. Remaining calm during this period ensures the bone plate stabilizes and heals properly.

• Initial Rest Period (Weeks 0–6): Dogs should stay confined to a crate or pen with only brief, supervised leash walks for bathroom breaks.
• Gradual Activity Increase (Weeks 6–10): Once X-rays confirm bone healing, your vet may approve gentle walking or light physical therapy.
• Long-Term Transition (After 10 Weeks): Controlled movement replaces full restriction. Activities like swimming or slow leash walks promote strength safely.
• Recovery Variations: Large or older dogs may need longer rest, while smaller breeds often heal faster due to lower joint stress.
• Vet-Guided Plan: Always follow your veterinarian’s recovery schedule and delay activity until your dog’s gait and confidence improve.

Patience during the calm phase prevents reinjury and ensures the surgical repair remains stable throughout the healing process.

Preparing a Safe Recovery Space Before Bringing Your Dog Home

Setting up a calm, controlled environment before your dog returns home is key to a smooth recovery. A secure space prevents accidental slips, jumping, or overexcitement while your dog adjusts to limited movement.

• Choose a Confined Area: Use a crate, playpen, or small gated room to limit running or climbing. Ensure there’s enough room to lie down comfortably.
• Provide Non-Slip Flooring: Mats or rugs prevent your dog from slipping on tiles or hardwood, reducing strain on the surgical leg.
• Use Soft Bedding: Thick, supportive bedding cushions the joint and prevents pressure sores during long rest periods.
• Keep Essentials Close: Place food, water, and toys within easy reach so your dog doesn’t need to move around unnecessarily.
• Minimize Noise and Distractions: Keep the space quiet and away from household traffic to maintain calm behavior.

A well-prepared environment helps your dog feel secure and relaxed, supporting both emotional and physical healing after surgery.

Crate Rest and Confinement Tips After TPLO Surgery

Crate rest is one of the safest ways to control your dog’s activity after TPLO surgery. When used correctly, it supports proper bone healing while reducing stress and the temptation to move too much.

• Purpose of Crate Rest: It restricts movement, preventing your dog from jumping, twisting, or running, which could damage the surgical site.
• Make the Crate Comfortable: Add soft bedding, a familiar blanket, and safe chew toys to make the space relaxing.
• Reduce Stress: Use calming scents or gentle music near the crate to create a peaceful environment.
• Positive Association: Feed meals or offer treats inside the crate so your dog views it as a safe, comforting space.
• Gradual Out-of-Crate Time: Once cleared by your vet, increase supervised movement slowly—starting with short walks or passive exercises.

Proper crate management helps your dog stay calm, safe, and comfortable throughout recovery without feeling isolated.

Using Calming Techniques and Tools After TPLO Surgery

Keeping your dog emotionally calm is as important as restricting physical activity. Calming tools and consistent routines help reduce anxiety during recovery.

• Soothing Sounds: Soft music or white noise masks outside distractions and helps anxious dogs relax.
• Natural Calming Aids: Pheromone diffusers, herbal sprays, or vet-approved supplements can reduce restlessness naturally.
• Predictable Routine: Regular feeding, potty breaks, and gentle interactions give structure and reassurance.
• Gentle Reassurance: Stay near your dog, speak calmly, and avoid sudden handling that could trigger anxiety or pain.
• Avoid Overstimulation: Limit visitors, children, or other pets from crowding your dog during recovery.

Combining environmental control with emotional support keeps your dog relaxed, promoting steady healing and preventing stress-related complications.

Managing Pain and Discomfort to Keep Dogs Calm

Unmanaged pain can make even the calmest dog restless after TPLO surgery. Pain relief not only promotes comfort but also prevents agitation and unwanted movement that could slow recovery.

• Follow Medication Instructions: Administer pain relievers and anti-inflammatories exactly as prescribed by your veterinarian.
• Watch for Signs of Pain: Whining, panting, or licking the surgical site may signal discomfort or medication wearing off.
• Monitor Activity Levels: A calm, comfortable dog rests easily; pacing or agitation may mean dosage adjustment is needed.
• Communicate with Your Vet: If pain persists despite medication, contact your vet before changing any drug schedule.
• Comfort Measures: Provide soft bedding, maintain room temperature, and ensure your dog rests undisturbed.

Consistent pain control encourages relaxation and speeds up healing by keeping stress levels low and mobility safe.

Mental Stimulation Without Physical Strain After TPLO Surgery

A calm mind leads to a calmer body. Mental enrichment keeps your dog engaged during rest without risking physical strain on the operated leg.

• Puzzle Feeders: Interactive feeding toys make mealtime mentally stimulating and extend eating time for restless dogs.
• Low-Impact Toys: Offer safe chew toys that keep your dog occupied without encouraging jumping or chasing.
• Gentle Obedience Training: Teach stationary cues like “stay,” “touch,” or “watch me” using treats and calm praise.
• Scent Games: Hide treats within reach to engage your dog’s nose and brain while keeping activity minimal.
• Supervised Interaction: Spend time nearby to provide emotional comfort and prevent boredom-related anxiety.

Mental stimulation helps reduce frustration during confinement and keeps your dog emotionally balanced throughout recovery.

Walking and Potty Breaks During the Recovery Period

Bathroom breaks must be short, calm, and strictly supervised during TPLO recovery. Controlled leash walks prevent slips, overexcitement, or sudden pulling that could harm the healing leg.

• Use a Short Leash and Harness: A well-fitted harness offers better control without straining the neck or back.
• Keep Walks Brief: Limit outings to 3–5 minutes, just long enough for your dog to relieve itself.
• Stable Ground: Choose grass or rubber mats over slippery concrete or tile surfaces.
• Avoid Stimulation: Steer clear of other dogs, loud noises, or distractions that might trigger sudden movement.
• Assist with Support: Some dogs benefit from a rear-end support sling during early recovery to maintain balance.

Calm, structured potty breaks maintain consistency while protecting the joint from unnecessary stress.

When to Seek Help for Restlessness After TPLO Surgery

Even with care, some dogs may struggle to stay calm during recovery. Persistent anxiety, restlessness, or agitation can interfere with healing and should not be ignored.

• Signs of Anxiety: Constant whining, pacing, or trying to escape confinement may indicate emotional distress.
• Excessive Movement: If your dog repeatedly gets up, circles, or limps after short walks, contact your vet for evaluation.
• Pain-Related Restlessness: Discomfort often shows as panting, licking the leg, or refusing to settle. Pain management adjustments may be necessary.
• Sedation Support: Vets can prescribe mild sedatives or calming medications for dogs who remain overly anxious.
• Separation Anxiety: If your dog becomes distressed when left alone, consider gradual desensitization or temporary companionship support.

Prompt veterinary guidance ensures your dog stays comfortable, safe, and mentally at ease throughout recovery.

Conclusion

Keeping your dog calm after TPLO surgery is just as important as the surgery itself. Controlled rest allows the bone, joint, and surrounding tissues to heal without stress or strain.

• Patience and Structure: A calm, predictable routine reduces anxiety and prevents sudden movements that can harm recovery.
• Balanced Care: Combine physical confinement with emotional comfort—soft bedding, quiet space, and gentle reassurance.
• Veterinary Support: Regular check-ins ensure pain and stress are properly managed throughout the healing period.

By creating a structured, peaceful recovery environment, you’ll help your dog heal faster, stay comfortable, and return to normal activity safely and confidently.

FAQs

How long should my dog stay confined after TPLO?

Most dogs need to remain confined for 6–8 weeks following TPLO surgery. During this time, movement should be limited to short, supervised leash walks for potty breaks. Your vet will confirm when it’s safe to expand your dog’s space or start physical therapy based on bone healing progress.

Can I leave my dog alone after TPLO surgery?

It’s best to avoid leaving your dog alone for long periods during the first few weeks. Dogs recovering from surgery can become anxious, restless, or try to move too much. If you must step out, keep your dog securely crated or in a small, safe area and use calming aids if recommended.

What if my dog keeps trying to run or jump?

Sudden movements can damage the surgical repair. Redirect energy through mental stimulation—like puzzle feeders or scent games—and keep your dog leashed when outside the crate. If restlessness continues, ask your vet about temporary calming supplements or mild sedatives to prevent setbacks.

Are sedatives safe to help my dog rest?

Yes, but only under veterinary supervision. Your vet may prescribe mild sedatives or anxiety-relief medications for dogs that struggle with confinement. These drugs are safe when dosed correctly and can prevent harmful overactivity that delays recovery.

How can I tell if my dog is in pain or anxious?

Signs include panting, whining, trembling, excessive licking of the incision, or refusing food. Pain and anxiety can look similar, so if you notice these behaviors, contact your vet. They can adjust pain medication or suggest additional calming support to help your dog relax.

Seroma formation is a common concern in dogs after TPLO surgery, which is a procedure to repair a torn cranial cruciate ligament. A seroma is a pocket of clear fluid that collects under the skin near the surgical site. This can cause swelling and discomfort for your dog after surgery.

Understanding what causes seromas, how to recognize them, and the best ways to manage and prevent them can help you support your dog’s recovery. This article explains seromas in detail and offers practical advice for pet owners.

What is a seroma after TPLO surgery in dogs?

A seroma is a fluid-filled swelling that develops under the skin near the surgical wound after TPLO surgery. It is not an infection but a collection of serum, the clear part of blood, that leaks from damaged blood vessels during surgery.

Seromas can vary in size and may feel soft or squishy. They usually appear within a few days after surgery and can last for several weeks if untreated.

• Fluid accumulation: Seromas form when serum collects in tissue spaces created by surgery, causing visible swelling near the incision site.
• Non-infectious nature: Unlike abscesses, seromas do not contain pus or bacteria, so they are not caused by infection.
• Common after TPLO: Because TPLO surgery involves cutting bone and soft tissue, seromas are a frequent postoperative complication.
• Self-limiting condition: Many seromas resolve on their own without treatment as the body reabsorbs the fluid.

Recognizing a seroma early helps differentiate it from infection or other complications. Your vet will examine the swelling and may use ultrasound to confirm the diagnosis.

Why do seromas form after TPLO surgery in dogs?

Seromas form due to the body’s response to tissue trauma during surgery. TPLO surgery involves cutting and moving bone and soft tissues, which can damage small blood vessels and lymphatics.

This damage allows serum to leak into the space under the skin, where it pools and creates a seroma. Several factors can increase the risk of seroma formation after TPLO surgery.

• Tissue disruption: Extensive cutting and manipulation of tissues during TPLO increase the chance of fluid leakage and seroma development.
• Dead space creation: Surgery can leave empty spaces under the skin where fluid can collect and form a seroma.
• Movement and activity: Early or excessive movement after surgery can worsen fluid accumulation by preventing proper healing.
• Inflammatory response: The body’s natural inflammation after surgery increases blood vessel permeability, promoting serum leakage.

Understanding these causes helps veterinarians take steps during and after surgery to reduce seroma risk.

What are the signs of seroma in dogs after TPLO surgery?

Detecting a seroma early can improve your dog’s comfort and prevent complications. Seromas usually appear as soft, swollen lumps near the surgical site.

Knowing what to look for helps you report concerns to your vet promptly for proper care.

• Visible swelling: A soft, raised lump near the incision that may increase in size over days after surgery.
• Squishy texture: The swelling feels fluid-filled and compressible rather than hard or painful.
• Minimal pain: Seromas often cause little to no pain, unlike infections which are usually tender.
• Clear or pale skin: The skin over the seroma looks normal without redness or heat, distinguishing it from infection.

If you notice swelling with redness, warmth, or discharge, contact your vet immediately as these signs suggest infection rather than a simple seroma.

How is seroma diagnosed after TPLO surgery?

Veterinarians diagnose seromas by physical examination and sometimes imaging. The goal is to confirm fluid accumulation and rule out infection or other complications.

Proper diagnosis ensures the right treatment and avoids unnecessary interventions.

• Physical exam: The vet will palpate the swelling to assess size, texture, and tenderness, helping differentiate seroma from abscess.
• Needle aspiration: Drawing fluid with a sterile needle can confirm the presence of clear serum typical of seromas.
• Ultrasound imaging: Ultrasound helps visualize fluid pockets under the skin and assess their extent.
• Laboratory tests: Fluid analysis checks for infection by looking for bacteria or inflammatory cells.

Early diagnosis allows for monitoring or treatment before the seroma worsens or becomes infected.

What treatment options exist for seroma in dogs after TPLO surgery?

Most seromas resolve without aggressive treatment, but some require intervention to prevent discomfort or infection. Treatment depends on the seroma size and symptoms.

Your vet will tailor care to your dog’s needs and monitor healing closely.

• Observation and rest: Small seromas often improve with rest and limited activity, allowing the body to reabsorb fluid naturally.
• Cold compresses: Applying cold packs can reduce swelling and inflammation during the first few days after surgery.
• Needle drainage: Large or persistent seromas may need fluid removal by sterile needle aspiration to relieve pressure.
• Compression bandaging: Gentle bandages can help prevent fluid accumulation and support tissue healing.

In rare cases, if a seroma becomes infected or does not resolve, surgical drainage or antibiotics may be necessary.

How can seroma formation be prevented after TPLO surgery in dogs?

Preventing seromas involves surgical technique and postoperative care. Your vet will use strategies to minimize tissue trauma and fluid buildup during and after TPLO surgery.

As a pet owner, you play a key role in helping your dog heal without complications.

• Meticulous surgery: Surgeons minimize tissue damage and close dead spaces carefully to reduce fluid leakage.
• Drain placement: Sometimes, drains are placed during surgery to remove excess fluid and prevent seroma formation.
• Restricted activity: Limiting your dog’s movement after surgery helps prevent fluid accumulation and promotes healing.
• Proper wound care: Keeping the incision clean and dry reduces inflammation and risk of complications.

Following your vet’s instructions closely after TPLO surgery is essential to reduce seroma risk and support recovery.

What complications can arise from untreated seromas after TPLO surgery?

If seromas are left untreated or become large, they can cause problems that affect your dog’s comfort and healing. Recognizing these risks helps you seek timely veterinary care.

Some seromas may become infected or delay wound healing, requiring more intensive treatment.

• Infection risk: Fluid pockets can become infected, turning into abscesses that need antibiotics or surgery.
• Delayed healing: Large seromas put pressure on the incision, slowing tissue repair and increasing scar tissue.
• Discomfort and pain: Persistent swelling can cause pain or limit your dog’s mobility during recovery.
• Wound breakdown: Excess fluid may cause the surgical wound to open, requiring additional veterinary intervention.

Early detection and treatment of seromas help avoid these complications and ensure a smoother recovery for your dog.

Conclusion

Seromas are a common but manageable complication after TPLO surgery in dogs. They form when clear fluid collects under the skin near the surgical site, causing swelling but usually not pain or infection.

Understanding what a seroma is, why it happens, and how to spot it helps you support your dog’s healing. Most seromas resolve with rest and simple care, but some need veterinary treatment to prevent complications. Following your vet’s advice on surgery and postoperative care is key to reducing seroma risk and ensuring your dog recovers comfortably.

What should I do if I notice swelling after my dog’s TPLO surgery?

If you see swelling near the incision, monitor it closely. Contact your vet promptly if the swelling grows, becomes painful, or shows redness or discharge to rule out infection or seroma complications.

Can seromas cause long-term problems for my dog?

Most seromas heal without lasting issues. However, untreated or infected seromas can delay healing and cause discomfort, so early veterinary care is important to prevent long-term problems.

Is it safe to drain a seroma at home?

Do not attempt to drain a seroma yourself. Needle aspiration must be done by a veterinarian under sterile conditions to avoid infection and complications.

How long does it take for a seroma to heal after TPLO surgery?

Small seromas often resolve within 1 to 3 weeks as the body absorbs the fluid. Larger seromas may take longer and sometimes require veterinary treatment.

Can physical therapy help prevent seromas after TPLO surgery?

Physical therapy helps recovery but should be started gradually and under veterinary guidance. Early or excessive activity can increase seroma risk, so follow your vet’s activity recommendations carefully.
