When Should I Worry About Swelling After Knee Surgery?
Your knee feels like it’s been through a war. That’s normal after surgery. But what about the swollen foot after knee surgery that seems to creep down your leg? You’re wondering, is this okay? Let’s break down when swelling is typical and when it’s a red flag.

The normal swelling phase
Right after knee surgery, swelling is expected. Your body is healing, and inflammation is part of that process. Expect some swelling for weeks, even months. It’s part of the recovery journey.
Why is my foot swollen after knee surgery?
Gravity plays a big role. After knee surgery, fluid can naturally flow down your leg, causing a swollen foot after knee surgery. Keep your leg elevated when resting.
When swelling becomes a concern
While some swelling is normal, certain signs should make you call your doctor. These include:
- Sudden Increase: If your swelling dramatically increases within a short period.
- Severe Pain: If the swelling is accompanied by intense pain that doesn’t respond to medication.
- Redness and Warmth: If the area around the swelling becomes very red or hot to the touch.
- Trouble Breathing: If swelling is present and you find yourself struggling to breathe or experiencing chest pain.
- Calf Pain: If you observe pain in your calf, this could indicate DVT(Deep Vein Thrombosis), a serious condition where a blood clot forms in a deep vein, most commonly in the legs, but can also occur in the arms or other veins
Understanding the timeline
- First Few Days: Expect significant swelling. Use ice and elevate your leg.
- Weeks After: Swelling will gradually decrease. You may still experience some swelling.
- Months After: Some mild swelling can persist for several months.
Managing swelling at home
- Elevation: Keep your leg elevated above your heart as much as possible.
- Ice: For therapeutic cooling, apply ice packs in 15 to 20 minutes, repeated throughout the day.

- Compression: Use compression bandages or stockings as recommended by your surgeon.
- Movement: Gentle exercises, as advised by your physical therapist, can help reduce swelling.
- Hydration: Drink plenty of water.
The role of physical therapy
Physical therapy is crucial for recovery. A therapist will provide a tailored exercise plan to help with a swollen foot after knee surgery, improving circulation and tracking progress.
Recognizing potential complications
Sometimes, excessive swelling can indicate a complication, such as:
- Infection: Redness, warmth, and increased pain can be signs of infection.
- Deep Vein Thrombosis (DVT): Calf pain, swelling, and redness can indicate a DVT.
- Hematoma: Blood accumulation at the surgical site.
