One hundred consecutive ABG (Anatomique Benoist Giraud, Howmedica) hydroxyapatite-coated hip arthroplasties in 97 patients were evaluated prospectively with a follow-up time of 4 to 10 years (mean, 6 years). Clinical results were excellent with an improvement in the Merle d'Aubigne score from 9 preoperatively to 17.4 at 5 years. Thigh pain was persistent in only 3%; it was mild in nature and controlled with simple analgesics. Kaplan-Meyer survivorship analysis was 100% for the femoral stem and 95% for the acetabular cup at 6 years. Of concern was the high polyethylene wear measured with an average of 0.24 mm/y (range, 0.05-0.76 mm/y).
