The purpose of the study was to determine whether isolated revision of the acetabular component can be successfully performed without disturbing the femoral stem and to determine the fate of the unrevised femoral stem following revision. Fifty-seven hips in 55 patients underwent isolated acetabular revision without removal of the femoral component. Thirty-three hips with minimal acetabular deficiency required no bone grafting; the remaining 24 hips were treated by morselized or structural allograft in addition to a new acetabular component. Twenty-two of these 24 hips demonstrated incorporation of the bone graft. A mean follow-up of 5.8 (5-9) years, all femoral and acetabular components were judged to be stable and well fixed.
