Recovering from a knee replacement surgery requires a combination of rest, proper care, and most importantly, knee replacement exercises. These exercises help improve movement, strengthen muscles, reduce pain, and speed up your overall recovery. The right knee replacement physiotherapy plan ensures that you get back to walking, climbing stairs, and performing daily activities comfortably.
Why Knee Replacement Exercises Are Important
After surgery, the knee joint becomes stiff, weak, and swollen. Regular exercise helps:
-
Restore movement
-
Improve flexibility
-
Reduce pain and swelling
-
Strengthen the knee muscles
-
Support walking and balance
-
Prevent future complications
Your physiotherapist will guide you according to your recovery stage, but here are the most recommended exercises.
