This study compared the results of limited femoral head resurfacing arthroplasty versus total hip arthroplasty (THA) for osteonecrosis. Thirty consecutive patients who had undergone a femoral head resurfacing procedure for osteonecrosis of the femoral head were compared with 30 consecutive patients who had undergone a THA. Both groups of patients had Steinberg stage III or IV disease with no acetabular cartilage involvement radiographically and by intraoperative inspection. At a 7-year mean follow-up for the resurfacing group and an 8-year mean follow-up for the THA group, the survival rate was 90% and 93% (P=.3). This study supports the femoral head resurfacing procedure as an alternative to THA for the time period studied.
