We assessed the effectiveness of total hip arthroplasty (THA) with cementless cups and femoral head autografts for patients with acetabular dysplasia. In 2004, we carried out primary cementless THA on 41 hips, using femoral head autografts on 31 hips. The cup was placed at the level of the true acetabulum and bone from the femoral head was used as the graft. A retrospective study was made of 31 hips (30 females and 1 male, average age 62 years). The average proportion of the acetabular cup covered by the femoral head autograft was 49.1% (range, 39.6-71.4%), and 10 hips had a cup coverage of more than 50%. The average follow-up period was 5 years. All autografts were united to the host bones. No autograft collapsed, and no component from the hip became loose in any of patients. THA with a cementless cup and a femoral head autograft for patients with osteoarthritis resulting from hip dysplasia can achieve a favorable outcome.
