A total knee replacement is a surgical procedure where damaged or worn-out parts of the knee joint are removed and replaced with artificial components. This surgery is often recommended for individuals suffering from severe arthritis or knee injuries that cause pain and limit mobility. The goal is to relieve pain and restore function in the knee. During the procedure, the surgeon makes an incision in the knee and removes the damaged cartilage and bone. The new artificial joint, typically made of metal and plastic, is then fitted into place. After surgery, patients usually undergo rehabilitation to regain strength and improve movement in the knee.
