we evaluated roentogenographically 38 total hip arthroplasties that were performed in combination with autogenous femoral head grafts to the acetabulum in 32 patients who had arthritis secondary to congenital displasia. The average period of follow-up was 6 years and 5 months (ranging from 5 to 9 years) ; the average age at operation was 53 (from 44 to 65) . The mean JOA score before surgery of 46 points increased to 86 points afterwards. All of the autogenous grafts had united with the host bone within 1 year and remodeling of the graft bone was observed on roentgenograms. But there was a 40% incidence of a radiolucent line between the bone graft and bone cement, and 1 hip had a continuous radiolucent zone at the acetabular component at the cement-bone interface.
