How Long Does Swelling Last After TPLO Surgery

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.
