Between March 2007 and July 2010, 1000 consecutive fully porous coated hip resurfacing arthroplasties (HRA) were performed by a single surgeon in 871 patients. The average length of follow-up was 3 ± 1 years. Three cases (0.3%) in three patients showed adverse wear related failures. Another 17 (1.7%) failures were identified at the time of this study. Using any failure of any component as the endpoint, the survivorship rate was 98.8% at two years and 97.4% at five years. Excluding the failed cases, all components were radiographically stable; there was only one partial femoral radiolucency seen. The clinical and radiological outcomes of this fully porous coated hip resurfacing were comparable to, if not better than, those reported by others using hybrid fixation methods at five years post-operatively.
2007年3月至2010年7月期间，一名外科医生为871例患者连续实施了1000例全多孔涂层髋关节表面置换术（HRA）。平均随访时间为3±1年。3例患者中的3例（0.3%）出现了与磨损相关的不良失败情况。在本研究时又发现了另外17例（1.7%）失败病例。以任何部件的任何失败作为终点，两年时的生存率为98.8%，五年时为97.4%。排除失败病例后，所有部件在影像学上均稳定；仅见一处股骨部分透亮区。这种全多孔涂层髋关节表面置换术的临床和影像学结果在术后五年时即便不比其他采用混合固定方法报道的结果更好，也与之相当。
