29 young patients with 33 arthritic hips had total hip replacement. Follow-up at 10 months showed that they were doing well, but at 5 years 57 per cent showed evidence of actual or potential loosening of at least one component of the prosthesis. Factors that seemed to adversely affect the results were an initial diagnosis of avascular necrosis, a previous mold arthroplasty, heavy activity on the part of the patient, a unilateral arthroplasty, and weight of more than 82 kilograms (180 pounds). Acetabular loosening occurred more than twice as frequently as femoral loosening.
