Bone preserving alternative to Hip Replacement

Thank you for your interest in our hip resurfacing procedure for younger, more active adults.

The following articles will introduce you to two innovative and conservative approaches to the treatment of hip disease. The first procedure is specifically designed for the treatment of stage III or early stage IV osteonecrosis, also known as avascular necrosis (AVN), in which the disease has not yet progressed to osteoarthritis. In these patients, the acetabular cartilage is relatively healthy (i.e., the hip joint is not yet "bone-on-bone") and, therefore, no artificial joint bearing is needed. This procedure is referred to as Precision-fit Surface Hemiarthroplasty.

The second procedure is designed specifically for patients with osteoarthritis in which both sides of the hip joint must be treated as a result of the degenerative condition of the cartilage. It is known as Metal-Metal Surface Replacement or hip resurfacing. An alternate bearing (e.g., metal-metal) is implanted rather than the conventional metal-polyethylene bearing in an effort to significantly improve implant durability for younger, more active patients.

Unlike conventional total hip replacement (THR), hip resurfacing is conservative in that the femoral head and neck of the hip joint are not removed, nor is bone removed from the femur. In the case of surface replacement, less bone is also removed from the acetabulum as compared to conventional THR since no polyethylene liner is used.
