Joint replacement is one of the most common and successful operations in modern orthopaedic surgery. It consists of replacing painful, arthritic, worn or diseased parts of the joint with artificial surfaces shaped in such a way as to allow joint movement.
Prognosis is good to excellent in 95% of major joint replacements (hips and knees). Pain relief is especially reliable. Full recovery of range of motion is not always accomplished.
Joint replacements are available for other joints on a limited basis, most notably shoulder, elbow, wrist, ankle, and fingers.
