HIP AND KNEE REPLACEMENT IN OSTEOGENESIS IMPERFECTA

Five total hip and three total knee arthroplasties were performed, fro m 1969 to 1990, in six patients who had osteogenesis imperfecta. The p atients who had a hip arthroplasty were followed for a mean of seven y ears, and those who had a knee arthroplasty, for a mean of ten years. Postoperatively, all had relief of pain and were able to walk; one pat ient used a walker and two used a cane. The only postoperative complic ation was an intrapelvic protrusion of the acetabular component six ye ars after a bipolar hip replacement.
