A total hip replacement procedure creates a new surface for the ball and socket mechanism of the hip. The top of the femur bone (the ball) and the acetabulum (the socket within the hip) are replaced with components constructed from metal alloys and polyethylene. The procedure is usually recommended for older patients that have advanced degenerative joint disease within the hip, resulting in severe pain and restricted mobility.
A hip replacement is usually performed after other treatment options have begun to show diminished effectiveness in controlling the pain of the degenerated hip, either while walking or at rest.
The typical candidate for a hip replacement is a patient over 55 years of age.
The primary goal of a hip replacement procedure is to greatly reduce pain and stiffness in the joint. The replaced hip will generally last between 15 and 20 years.
Surgery removes the damaged joint, and then replaces the contact or functional points of the hip and thighbone with metal alloy and polyethylene (plastic) implants.
