We used radiostereometric analysis to compare wear rates between uncemented porous sockets and cemented all-polyethylene sockets in a series of 102 hips randomised for either a Harris-Galante or a Charnley cup. Wear was evaluated in 95 hips at a mean of five years (2 to 7). All hips had a cemented, 22 mm head mono-bloc Charnley stem. The mean annual wear rate was 0.09 mm in the Charnley sockets and 0.10 mm in the Harris-Galante sockets, with no statistically significant differences in wear, migration or rotation. We conclude that, up to five years, the wear characteristics of the modular and porous Harris-Galante socket resemble that of the Charnley socket.
我们采用放射性立体测量分析方法，对102例随机接受Harris-Galante杯或Charnley杯置换的髋关节中，非骨水泥多孔髋臼杯与骨水泥全聚乙烯髋臼杯的磨损率进行比较。对95例髋关节进行了平均五年（2至7年）的磨损评估。所有髋关节均采用骨水泥固定、22毫米头部的一体式Charnley股骨柄。Charnley髋臼杯的年平均磨损率为0.09毫米，Harris-Galante髋臼杯为0.10毫米，磨损、移位或旋转方面无统计学显著差异。我们得出结论，在长达五年的时间里，模块化多孔Harris-Galante髋臼杯的磨损特征与Charnley髋臼杯相似。
