In a matched-pair study of primary total hip arthroplasty, 45 all-polyethylene cemented acetabular components were compared with 45 cementless, hemispheric, titanium acetabular components. At 9 to 12 years, 1 of the cemented acetabular components was revised for aseptic loosening, and 14 (31%) were radiographically loose. Nine (20%) cemented acetabular components had pelvic osteolysis. In the cementless acetabular component group, 2 well-fixed components were revised. No components were radiographically loose, and 3 (7%) had pelvic osteolysis. Thirty-eight (97%) of the patients in each group were satisfied with the surgery. The clinical results of the cemented and cementless components were excellent. The cementless components had less loosening (P <.001) than the cemented components.
在一项初次全髋关节置换术的配对研究中，将45个全聚乙烯骨水泥固定髋臼组件与45个非骨水泥半球形钛髋臼组件进行了比较。在9至12年时，1个骨水泥固定髋臼组件因无菌性松动而翻修，14个（31%）在影像学上出现松动。9个（20%）骨水泥固定髋臼组件出现骨盆骨溶解。在非骨水泥髋臼组件组中，2个固定良好的组件进行了翻修。没有组件在影像学上出现松动，3个（7%）出现骨盆骨溶解。每组38名（97%）患者对手术满意。骨水泥固定和非骨水泥组件的临床结果均极佳。非骨水泥组件的松动情况比骨水泥组件少（P<.001）。
