Knee Replacement

What is Knee Replacement?

Knee replacement is also known as knee arthroplasty. It is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis, and for other knee diseases such as rheumatoid arthritis and psoriatic arthritis. It can either be a total or partial replacement.

How can physiotherapy help patients undergoing a knee replacement surgery?

Pre-operative physiotherapy will help prepare your knee and its surrounding muscles for surgery because the better the state of your muscle strength and range of movement before surgery, the better the recovery rate after surgery.

Post-operative physiotherapy is also important in pain and swelling reduction, as well as, returning your knee back to a functional state after surgery.
