Primary total hip arthroplasty with a flanged, cemented all-polyethylene acetabular component: evaluation at a minimum of 20 years.

Abstract

One hundred twenty-three consecutive primary total hip arthroplasties in 107 patients were performed with the insertion of a cemented, all polyethylene, flanged acetabular component. At a minimum of 20 years, 66 patients had died (75 hips) and 8 patients (8 hips) were lost to follow-up evaluation, leaving 40 hips in 33 patients. At a mean of 21.1 years, 2 cups had been revised for aseptic loosening, one well-fixed cup was revised at the time of femoral component revision, and 4 additional cups had definite evidence of radiographic loosening. Survivorship analysis revealed a 77.3% survivorship for the component at 21 years, with revision or definite loosening as an endpoint (95% confidence interval, 67.8%-86.8%).
