Effectiveness of total hip arthroplasty in the management of hip osteonecrosis.

Total hip replacement initially showed universally bad results when performed in hips with advanced stages of osteonecrosis. Newer techniques and implants remarkably improved these results. Today cementless or hybrid total hip arthroplasty for osteonecrosis is proven to be safe and effective and to have survivorship similar to cases with osteoarthritis. Newer,more durable bearing surfaces will further improve the longevity of this procedure.
