Home / Total Knee Replacement Surgery
Total knee replacement is a surgical procedure which involves replacing a diseased knee joint with artificial material. The knee is a “hinge” joint that is placed at the point where the thigh meets the shin bone. During a total knee replacement surgery, the end of the thigh bone is removed and replaced with a metal part.
