Hip replacement is a predictable and reliable operation to relieve the symptoms of hip arthritis. It is one of the most successful surgical procedures in medicine and was called a miracle of modern medicine by a leading medical journal 50 years after its introduction.
During this procedure, the damaged bone and cartilage of the hip is removed, and replaced with prosthetic implants.
The deteriorated femoral head is removed, and replaced with a metal stem. This stem is “press fit” or cemented into the center of the femur (thigh) bone. On the upper portion of the metal stem, either a metal or ceramic ball is placed.
This ball acts as the new femoral head. To replace the socket (acetabulum), the damaged cartilage is removed and a metal socket is placed.
Sometimes, cement or screws are used to secure the socket. A dense plastic liner is placed between the new socket and ball, allowing for smooth movement of the new joint.
