What a knee replacement is

Total knee replacement

A total knee replacement is surgery to replace a worn knee joint with an artificial one. It is often done when osteoarthritis has made the knee painful and stiff.

The surgeon removes the damaged surfaces and fits new parts, so the knee can bend and carry weight again.

This matters because the recovery after surgery decides how well the new knee works. Without movement, the joint can stay stiff and weak.

Physiotherapy is a central part of this recovery. It does not replace the surgery, but it turns the new joint into a knee you can trust.

At home our physiotherapist works on bending the knee, straightening it fully, building the thigh muscles and walking safely. Steady daily practice helps swelling settle and restores confident, independent movement over the weeks.
