Arthroplasty is a surgical procedure to reconstruct or replace the integrity and function of a joint. A joint can be restored by reshaping the bones or replacing it with metal or plastic parts like a prosthesis. Although many types of arthritis may affect the joints, osteoarthritis is the most common reason for arthroplasty.

When medical treatments are no longer adequate in providing relief from joint pain and/or disability, arthroplasty may be recommended. Most joint surgery involves the hip and knee, and less commonly on the ankle, elbow, shoulder, and fingers. Arthroplasty can relieve pain and restore enough function in a joint to allow a person to do normal daily activities; and provide substantial improvement in the patient’s quality of life.
