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.
对27例髋关节（23例患者）进行了回顾性临床和影像学分析，这些患者均植入了带圆柱形衬垫的带螺纹、多孔涂层髋臼组件（烧结T型片 - ST杯，Biomet公司，印第安纳州华沙）。16例髋关节采用骨水泥固定柄；11例采用非骨水泥、周向多孔涂层柄。临床和影像学平均随访期为68个月。患者平均年龄为49岁；平均体重为68千克。线性磨损率和体积磨损率分别为每年0.25毫米和每年149立方毫米。骨溶解发生在51.8%（14例髋关节）。磨损率和年轻与骨溶解相关（P分别为0.0002和0.01）。未发生股骨远端骨溶解病例。
