The orhopedist surgically removes a painful hip joint with arthritis and replaces it with an artificial joint often made from metal and plastic components. It usually is done when all other treatment options have failed to provide adequate pain relief.
Knee replacement, also called knee arthroplasty or total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury.
The surgery to correct a torn knee ligament involves replacing the ligament with a piece of healthy tendon. A tendon from the kneecap or hamstring, for example, is grafted into place to hold the knee joint together.
