Polyethylene wear and periprosthetic osteolysis in metal-backed acetabular components with cylindrical liners. Academic Article uri icon

Overview

abstract

  • A retrospective clinical and radiographic analysis was performed in 27 hips (23 patients), in which a threaded, porous-coated acetabular component with cylindrical liner was implanted (Sintered T-Tab-ST cup, Biomet, Warsaw, IN). Sixteen hips had cemented stems; 11 had cementless, circumferentially porous-coated stems. The mean clinical and radiographic follow-up period was 68 months. The mean patient age was 49 years; the mean patient weight was 68 kg. The mean rates of linear and volumetric wear were 0.25 mm/y and 149 mm3/y, respectively. Osteolysis occurred in 51.8% (14 hips). Wear rate and young age correlated with osteolysis (P = .0002 and P = .01, respectively). There were no cases of distal femoral osteolysis.
