Sixty consecutive patients (60 hips) were allocated in two matched-pair groups. Patients were matched for age, gender, body mass index, level of activity, and bone stock. Both groups received an uncemented total hip arthroplasty with a modular press-fit cup and an alumina femoral head. In the first group, an acetabular liner made of polyethylene was used; in the second group, an alumina liner. Both groups were followed for a minimum of 5 years. No hip required revision, and there was no radiographic evidence of aseptic loosening in either group. Mean Harris hip score was 94.7 (87.1-99) points in the polyethylene group and 93 (88.5-100) points in the alumina group.
连续60例患者（60髋）被分为两个配对组。患者在年龄、性别、体重指数、活动水平和骨量方面进行了匹配。两组均接受了非骨水泥型全髋关节置换术，使用模块化压配髋臼杯和氧化铝股骨头。第一组使用聚乙烯髋臼内衬；第二组使用氧化铝内衬。两组均随访至少5年。两组均无髋关节需要翻修，且影像学检查均未发现无菌性松动迹象。聚乙烯组的平均Harris髋关节评分为94.7（87.1 - 99）分，氧化铝组为93（88.5 - 100）分。
