自20世纪80年代末以来，第二代金属对金属关节面已被用作替代关节面，以消除聚乙烯磨损导致的无菌性松动。本研究旨在评价一系列Metasul（Zimmer GmbH，温特图尔，瑞士）金属对金属全髋关节置换术（THA）的长期结果。在111名连续患者中使用28 mm Metasul关节面进行了149例非骨水泥型THA。在术后13年对结果进行了回顾性分析。进行了临床和影像学评价以及种植体存活率。7例髋关节（4.7%）翻修。以任何原因翻修作为终点的总体生存率为0.94。平均Harris髋关节评分为91.4。4个髋关节在股骨柄附近发现膨胀性骨溶解。金属磨损相关的无菌性松动不是我们Metasul金属对金属THA失败的主要原因。复发性脱位是我们病例中翻修的主要原因。
Second-generation metal-on-metal bearings have been used since the late 1980s as alternative bearings to eliminate aseptic loosening due to polyethylene wear. The aim of the present study was to evaluate the long-term results of a series of Metasul (Zimmer GmbH, Winterthur, Switzerland) metal-on-metal total hip arthroplasty (THA). One hundred forty-nine cementless THAs with a 28-mm Metasul articulation were performed in 111 consecutive patients. The results were retrospectively reviewed at 13 years postoperatively. Clinical and radiographic evaluations and implant survivorship were performed. Seven hips (4.7%) were revised. The overall survivorship with revision for any reason as the end point was 0.94. The average Harris hip score was 91.4. Expansive osteolysis was found adjacent to the stem in 4 hips. Metal wear related aseptic loosening was not the major reason for failure in our Metasul metal-on-metal THAs. Recurrent dislocation was the main reason for revision in our series.
