摘要：

Between 1986 and 1997, 136 porous-coated anatomic (PCA) total hip arthroplasties were performed for patients with osteoarthritis of the hip, and data were available for 60 hips at final follow-up (mean follow-up, 15.2 years). Of these, 18 hips had undergone revision: 12 for the acetabular component, 10 for the femoral component, and 4 for both components. Survival rate at 23 years postoperatively was 60% for the acetabular component and 82% for the femoral component. Multivariate Cox proportional hazards regression showed that annual polyethylene wear rate, size, and abduction angle of the acetabular component were significantly associated with acetabular component revision surgery, and that annual polyethylene wear rate and filling ratio of the femur were associated with femoral component revision surgery.
