A Staph infection after TPLO surgery is a bacterial infection caused by Staphylococcus species at the surgical site. These infections happen when bacteria enter the incision, leading to inflammation, pain, swelling, and, in severe cases, delayed healing or implant issues.

The most common bacteria involved are

• Staphylococcus pseudintermedius (S. pseudintermedius is naturally found on a dog's skin and can become problematic after surgery.)
• Staphylococcus aureus (S. aureus is less common in dogs but can still cause serious infections, sometimes resistant to antibiotics like MRSA.)

TPLO surgeries are particularly prone to infection because of the metal implants, which provide a surface for bacteria to stick to and form biofilms. Additionally, open incisions, surgical trauma, and a dog's licking or scratching increase the risk of infection.

Using proper sterile techniques, taking care of the wound after surgery, and detecting infections early are crucial for preventing complications and ensuring a smooth recovery.

‍

TL;DR

• Staph infections after TPLO surgery are rare but can happen, with Staphylococcus pseudintermedius being the most common culprit.
• Early treatment with antibiotics is crucial as infections typically won't heal on their own and can lead to serious complications.
• Untreated infections may cause osteomyelitis, implant failure, or systemic illness, requiring more invasive treatments.
• Proper post-op care and monitoring the incision site are key to preventing infections.
• If an infection is severe, the TPLO plate may need to be removed to prevent further complications.

‍

Causes of Staph Infection After TPLO Surgery

Staph infections after TPLO surgery occur when Staphylococcus bacteria enter the surgical site, multiply, and trigger an inflammatory response. These infections can develop due to various factors, often related to contamination, improper wound care, or the dog's overall health.

Surgical Site Contamination - Even with strict sterile protocols, bacteria from the skin, surgical instruments, or operating room can enter the incision. Staphylococcus pseudintermedius is naturally found on a dog's skin and may infect the site if proper antiseptic measures are not followed.

Improper Wound Care - After surgery, poor wound management increases infection risk. If bandages are not changed regularly, the incision is exposed to dirt, or the dog licks the wound, bacteria can enter. Delayed healing also creates an opportunity for bacterial overgrowth.

Weakened Immunity - Dogs with weakened immune systems due to age, chronic illnesses (like diabetes or Cushing’s disease), or prolonged use of immunosuppressive medications are more vulnerable to infections. Their bodies struggle to fight bacteria, increasing the risk of severe complications.

Hospital-Acquired vs. Environmental Bacteria - Hospital-acquired infections, often resistant to antibiotics (e.g., MRSA), pose a serious threat. Environmental bacteria, from bedding, floors, or other animals, can also infect wounds if hygiene is inadequate. Proper post-op care and monitoring are essential for prevention.

Risk Factors for Developing Infections Post-TPLO

Several factors increase the risk of Staph infection after TPLO surgery, including dog-related, surgical, and post-op care factors. Understanding these risks helps in preventing complications and ensuring a smooth recovery.

Dog-Related Factors

Certain dogs are more prone to infections. Older dogs, immunocompromised pets (diabetes, Cushing’s disease), and breeds with skin folds (like Bulldogs) are at higher risk due to weaker immune defenses or bacterial colonization. Overweight dogs also have reduced blood flow to the incision, slowing healing.

Surgical Factors

Implant contamination is a major concern, as metal plates provide a surface for bacteria to form biofilms, making infections harder to treat. Prolonged surgery times, non-sterile conditions, and inadequate antibiotic prophylaxis increase infection risk.

To minimize this, many surgeons use Simini Protect Lavage, a non-antibiotic surgical lavage that helps reduce bacterial contamination and biofilm formation on implants, lowering the chances of post-op infections.

Post-Op Care Factors

Excessive licking, poor hygiene, and delayed wound healing significantly raise infection risks. Dogs licking their incision introduce bacteria, while unclean bedding and surroundings expose wounds to environmental contaminants. Owners must follow strict post-op wound care guidelines and monitor for early signs of infection.

Symptoms of a Staph Infection After TPLO Surgery

Recognizing the early signs of Staph infection after TPLO surgery is crucial for timely treatment. Infections can range from mild to severe, potentially leading to implant complications or systemic illness if left untreated.

Early Signs - In the initial stages, the infection may cause redness, swelling, and warmth around the incision site. Mild discomfort is normal post-surgery, but persistent inflammation or increasing pain could indicate bacterial activity. Some dogs may start licking or chewing the incision, further worsening the condition.

Moderate Symptoms - As the infection progresses, pus or thick discharge may develop, often accompanied by a foul odor. The incision may start to separate or appear moist and inflamed. Dogs might also show signs of discomfort, such as limping, stiffness, or reluctance to bear weight on the affected leg. These symptoms suggest that the infection is spreading deeper into the tissue.

Severe Symptoms - In advanced cases, the infection can lead to systemic illness, causing fever, lethargy, loss of appetite, and general weakness. If bacteria spread to the bone or implant, it can result in implant loosening or failure, requiring urgent medical intervention. Immediate veterinary attention is needed to prevent complications and ensure proper healing.

How Staph Infections Are Diagnosed After TPLO Surgery

Diagnosing a Staph infection after TPLO surgery requires a thorough veterinary examination, laboratory tests, and sometimes imaging to assess the severity of the infection and its impact on the surgical site.

Veterinary Examination and Wound Assessment

A veterinarian will start by visually inspecting the incision site for signs of infection, such as redness, swelling, pus, or a foul odor. They will also check for pain, heat, and any abnormal discharge. If the dog is limping, lethargic, or showing signs of discomfort, it may indicate a deeper infection affecting the bone or implant.

Lab Tests: Bacterial Culture and Antibiotic Sensitivity

To confirm a Staph infection, a bacterial culture is performed by collecting a sample from the infected area. This test identifies the specific bacteria causing the infection, typically Staphylococcus pseudintermedius or Staphylococcus aureus.

Antibiotic sensitivity testing is then conducted to determine which antibiotics will be most effective, especially important for resistant strains like MRSP (Methicillin-Resistant Staphylococcus pseudintermedius).

Imaging Methods for Implant-Associated Infections

If an infection is suspected to have spread to the bone or implant, X-rays or advanced imaging like CT scans may be used. These help detect signs of bone lysis, implant loosening, or deep tissue infection, which could require additional surgical intervention. Early diagnosis is crucial to prevent complications and improve treatment outcomes.

The Role of Multidrug-Resistant Bacteria in TPLO Infections

One of the biggest challenges in treating Staph infections after TPLO surgery is the presence of multidrug-resistant bacteria, particularly Methicillin-Resistant Staphylococcus pseudintermedius (MRSP). This bacterial strain has developed resistance to many commonly used antibiotics, making infections harder to treat and increasing the risk of complications.

What is MRSP?

MRSP is a resistant form of Staphylococcus pseudintermedius, a bacterium normally found on a dog’s skin. In healthy dogs, it rarely causes issues, but after TPLO surgery, it can infect the surgical incision and implants, leading to persistent infections. MRSP is similar to MRSA (Methicillin-Resistant Staphylococcus aureus) in humans, making it difficult to eliminate with standard antibiotics.

Why Traditional Antibiotics May Not Work

Since MRSP is resistant to beta-lactam antibiotics (penicillins and cephalosporins), commonly prescribed antibiotics may be ineffective. Inappropriate antibiotic use can worsen resistance, making treatment options more limited. Infected implants and biofilm formation further protect the bacteria, requiring alternative treatments.

Impact on Treatment Complexity and Recovery Time

Resistant infections prolong recovery, as stronger antibiotics, prolonged treatment, or even implant removal may be necessary. In severe cases, advanced antimicrobial therapies, surgical debridement, or alternative infection-control measures like Simini Protect Lavage may be required to manage the infection and prevent recurrence. Early culture and sensitivity testing is essential for selecting the most effective treatment.

How Biofilms on Implants Worsen Staph Infections

Biofilms are colonies of bacteria that form a protective layer on surfaces, such as TPLO plates and screws. In post-surgical infections, Staphylococcus pseudintermedius and other bacteria can attach to the metal implant, creating a slimy, protective matrix that shields them from antibiotics and the immune system.

How Biofilms Form on TPLO Implants

After TPLO surgery, bacteria from the skin, surgical instruments, or environment can adhere to the implant. Once attached, they produce a sticky extracellular substance, allowing them to grow and form a dense bacterial community. These biofilms anchor bacteria to the implant surface, making infections harder to eradicate.

Why Biofilms Resist Antibiotics and Immune Responses

Biofilms create a physical and chemical barrier that prevents antibiotics from fully reaching the bacteria. Additionally, bacteria within biofilms enter a dormant state, reducing their susceptibility to drugs that typically target active bacterial growth. The immune system also struggles to clear biofilms, as white blood cells cannot penetrate the bacterial layer effectively.

Treatment Challenges and Surgical Interventions

Because biofilm-associated infections are difficult to treat, prolonged antibiotic therapy alone is often ineffective. In severe cases, surgical debridement or implant removal may be required.

Many surgeons use Simini Protect Lavage during TPLO procedures to reduce bacterial adhesion and biofilm formation, helping to lower the risk of persistent infections.

Complications of Staph Infection After TPLO Surgery

A Staph infection after TPLO surgery can lead to severe complications if not treated promptly. The presence of metal implants, biofilm formation, and antibiotic-resistant bacteria make these infections particularly challenging.

• Implant Rejection or Failure - When bacteria colonize the TPLO plate, they can cause loosening of the implant, preventing proper bone healing. The immune system may recognize the infection as a foreign threat, triggering chronic inflammation and implant rejection. In severe cases, implant removal and revision surgery are required.
• Chronic Infections Leading to Osteomyelitis - Untreated or persistent infections can spread to the bone, causing osteomyelitis (bone infection). This condition leads to bone destruction, pain, and ongoing inflammation. Osteomyelitis often requires long-term antibiotics, surgical debridement, and sometimes implant removal to eliminate infected tissue.
• Increased Surgical Costs and Prolonged Recovery - Managing an infection often involves extended hospitalization, additional lab tests, imaging, and stronger antibiotics, significantly increasing treatment costs. The healing process is also delayed, prolonging the dog's discomfort and recovery timeline.
• When Amputation Might Become Necessary - In rare and extreme cases, if the infection is severe, untreatable, or has caused significant bone damage, limb amputation may be the only option to prevent systemic infection and further suffering. Early intervention is critical to avoid this drastic measure.

Treatment Options for Staph Infection Post-TPLO Surgery

Antibiotic Therapy

Common antibiotics for Staph infections include Clindamycin and Cephalexin, but resistant strains like MRSP require targeted antibiotics based on culture and sensitivity testing. If standard treatments fail, fluoroquinolones or chloramphenicol may be necessary. Completing the full antibiotic course is essential to prevent recurrence and resistance. Improper use of antibiotics can worsen resistance, making future infections harder to treat.

Surgical Interventions

If the infection is severe or antibiotics fail, surgical debridement is required to remove infected tissue and biofilm. In persistent infections, implant removal or revision surgery may be necessary. Surgeons may use antibiotic-impregnated beads to deliver localized medication directly to the infected site. This approach helps manage deep infections while preserving limb function, reducing the need for implant removal.

Supportive Care & Wound Management

Topical treatments like chlorhexidine and silver-based dressings help control bacterial growth at the incision. Proper wound cleaning, bandaging, and preventing licking are essential for recovery. Pain management with NSAIDs or opioids reduces discomfort, while anti-inflammatory medications control swelling. Supportive care ensures healing and prevents the infection from worsening or spreading further.

Why Early Detection and Intervention Are Crucial

Early detection and intervention are essential in preventing serious complications from Staph infections after TPLO surgery. The longer an infection goes untreated, the more likely it is to spread and cause severe complications such as osteomyelitis (bone infection), implant failure, or systemic illness. Timely treatment helps limit the damage, reduce recovery time, and avoid costly surgical interventions.

How Early Treatment Prevents Serious Complications - When infections are caught early, antibiotics can effectively control the bacteria before it forms a biofilm on the implant, making it resistant to treatment. Early intervention reduces the chances of bone destruction, chronic infections, and the need for implant removal or amputation.

When to Consult a Vet Immediately - If your dog shows any signs of infection, such as increased swelling, redness, warmth, or pus at the incision site, limping, lethargy, or fever, contact your vet immediately. Foul-smelling discharge or worsening symptoms require urgent attention, as they indicate that the infection is spreading.

The Importance of Regular Follow-Ups After TPLO Surgery - Post-surgery follow-ups are crucial for monitoring the surgical site and identifying early signs of infection. Regular check-ups help ensure that any issues are detected before they develop into more severe problems, ensuring the best possible recovery and reducing the risk of complications.

How to Prevent Staph Infections After TPLO Surgery

Pre-Surgical Prevention

Preventing Staph infections starts before surgery with proper planning. The sterile surgical environment is crucial in minimizing contamination during the procedure. Surgeons should follow strict sterilization protocols to prevent bacteria from entering the wound.

For high-risk dogs, pre-operative antibiotic protocols are recommended, especially if the dog has underlying health conditions like diabetes or is older, as these factors can weaken the immune system and increase infection susceptibility.

Post-Surgical Care Guidelines

Post-surgery, wound monitoring and cleaning are essential for preventing infection. Keep the surgical site dry and clean, changing bandages as instructed. Using an e-collar (cone of shame) can help prevent your dog from licking or biting the wound, which can introduce bacteria.

When your dog suffers a knee injury, you might hear the term TPLO from your veterinarian. But what does TPLO stand for in veterinary medicine? Understanding this term is important if your pet needs surgery for a torn cruciate ligament.

TPLO stands for Tibial Plateau Leveling Osteotomy. It is a common surgical procedure used to stabilize the knee joint in dogs after a cranial cruciate ligament (CCL) rupture. This article explains what TPLO means, why it is used, and what you can expect if your dog needs this surgery.

What Does TPLO Stand For and What Is Its Purpose?

TPLO stands for Tibial Plateau Leveling Osteotomy. It is a surgical technique designed to change the angle of the tibial plateau, which is the top part of the shin bone that forms the knee joint.

The purpose of TPLO surgery is to stabilize the dog's knee after the cranial cruciate ligament is torn. This ligament normally prevents the tibia from sliding forward under the femur. When it ruptures, the knee becomes unstable and painful.

• Tibial Plateau: The flat surface at the top of the tibia bone that forms part of the knee joint and affects joint stability.
• Leveling Osteotomy: A surgical cut made in the tibia to rotate and flatten the tibial plateau angle, reducing joint instability.
• Stabilization Goal: TPLO aims to stabilize the knee without relying on the damaged ligament, allowing normal movement.
• Pain Reduction: By stabilizing the joint, TPLO reduces pain and improves mobility in affected dogs.

After TPLO surgery, the altered tibial plateau angle stops the tibia from sliding forward during weight-bearing. This helps dogs regain normal knee function and reduces arthritis progression.

Why Is TPLO Surgery Recommended for Dogs?

TPLO surgery is often recommended for dogs with cranial cruciate ligament tears because it offers better long-term outcomes compared to other treatments.

Dogs with CCL injuries experience pain, lameness, and joint instability. TPLO surgery addresses these issues by mechanically stabilizing the knee, which helps dogs return to normal activity faster.

• Effective Stabilization: TPLO provides strong mechanical stability, improving joint function better than some non-surgical options.
• Faster Recovery: Dogs often regain mobility quicker after TPLO compared to conservative management or other surgeries.
• Reduced Arthritis: TPLO can slow down arthritis development by stabilizing the joint and reducing abnormal wear.
• Suitable for Active Dogs: TPLO is ideal for medium to large dogs that need durable knee stability for active lifestyles.

Veterinarians usually recommend TPLO for dogs weighing over 15 kg or those with severe ligament damage. It is considered the gold standard for treating CCL ruptures in many cases.

How Is TPLO Surgery Performed?

TPLO surgery involves making a precise cut in the tibia bone and rotating it to change the slope of the tibial plateau. This procedure requires specialized surgical skills and equipment.

The surgeon first makes an incision over the knee, exposes the tibia, and uses a saw to cut the bone. Then the tibial plateau is rotated to a more level position and fixed with a metal plate and screws.

• Bone Cut: A curved cut is made in the tibia to allow rotation of the tibial plateau to a new angle.
• Plate Fixation: A specially designed metal plate and screws hold the rotated bone segment securely in place.
• Joint Inspection: The surgeon inspects the knee joint for cartilage damage or meniscal tears during surgery.
• Postoperative Care: Proper wound closure and pain management are critical after surgery for healing.

TPLO surgery typically takes 1 to 2 hours and requires general anesthesia. After surgery, dogs need restricted activity and rehabilitation to recover fully.

What Are the Benefits of TPLO Surgery for Dogs?

TPLO surgery offers several benefits for dogs suffering from cruciate ligament injuries. It improves their quality of life by restoring knee function and reducing pain.

Compared to other treatments, TPLO has higher success rates and better long-term outcomes in many cases.

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.
