Overview
Knee replacement surgery can greatly reduce pain, but the operation is only half the story. Rehabilitation helps you regain movement, rebuild strength and walk with confidence.
Early, guided exercise is one of the most important parts of a successful knee replacement recovery.
The first two weeks
The focus is on safe movement, managing swelling and starting gentle exercises to bend and straighten the knee. You will usually walk with a frame or crutches.
Weeks three to eight
- Improving how far your knee bends and straightens
- Strengthening the thigh and hip muscles
- Walking further with less support
- Practising stairs and getting in and out of a car
After two months
Most people return to many everyday activities. Exercises continue to build strength, balance and endurance so you can get back to the things you enjoy.
When to call your doctor
Contact your surgeon or seek urgent care if you notice redness, heat or discharge from the wound, fever, calf pain or swelling, chest pain, or sudden shortness of breath.
Key takeaways
- Rehabilitation starts within days of surgery.
- Bending the knee early and building thigh strength are key goals.
- Recovery continues for months — steady effort pays off.
