Joint Replacement

Joint replacement means removing part or all of a damaged joint and installing hardware to allow the limb to move without pain or limitations. The replacement hardware is called a prosthesis. These are made of plastic, metal, ceramic, or a combination of these materials. Most joint replacements are performed to treat damage from arthritis to the knees or hips. Orthopedic surgeons do the procedure under general anesthesia.

A hospital stay of a day or two is typical for knee or hip joint replacement. Physical therapy then helps the muscles around the new joint to get strong. Joint hardware can last 15 to 20 years or more, depending on the type and the person’s level of physical activity.
