Total Joint Replacement





A total joint replacement is a surgical procedure which results in an arthritic or damaged joint being removed and replaced with an artificial joint. The artificial joint is made of various combinations of metal, ceramics, and plastics.

A joint is formed where two or more bones are joined together and supported by ligaments and other soft tissues. At the joint, the end of each bone is covered with a smooth layer called cartilage. Normal cartilage is so smooth that it allows painless motion. Additionally, the inside of every joint is lined by a smooth lining tissue, called synovium. The synovium produces fluid that lubricates the joint and reduces friction.

The cartilage or synovium can become damaged or diseased by arthritis. This results in a stiff and painful joint.

There are a number of non-surgical and surgical treatments for these painful joints. After the non-surgical treatments of arthritis, which include medications, exercises and life style changes, injections, and physical therapy, are no longer effective, you and one of our board certified surgeons can discuss the surgical options with you. The total joint replacement is the treatment that is used when the others are no longer successful.

The most commonly replaced joint is the knee. When the arthritic knee requires replacement, the damaged ends of the bones in the knee are replaced by metal and plastic.

The second most commonly replaced joint is the hip. The hip is a ball and socket joint. The hip replacement results in replacing the damaged ball (the upper end of the femur) with a metal or ceramic ball attached to a metal stem fitted into the femur. The socket of the hip joint is in the pelvis. When the hip socket requires replacement, it is replaced by a metal and/or plastic socket. The metals that are utilized include stainless steel, cobalt and chrome alloys, titanium, zirconium, tantalum, and vanadium. The plastic materials that are used are very durable and wear resistant material. Very exact bone cuts are made during total joint replacement so that many of the components can be press fit into the bone. In some cases plastic bone cement is used to secure the prosthesis components into the bone. These artificial materials and precise techniques allow the replaced joint to move like a normal joint.

Ongoing medical research and development are resulting in continued improvements in total joint replacement surgery. Our surgeons pride themselves in keeping abreast of the improvements and utilizing them for the benefit of our patients. The total joint replacement results in a dramatically improved quality of life and mobility.
