对美国（183 个插槽和 178 个股骨假体）和日本（145 个插槽和 148 个股骨假体）系列进行的初次查恩利全髋关节置换术 (THA) 进行了 10 至 20 年的比较，每个系列均由同一家医院的一名外科医生使用相似的技术进行。日本系列的主要病因是髋关节发育不良（70%），美国系列的主要病因是原发性骨关节病（50%）。在 4 至 11 年的随访中，日本系列的放射线插座存活率较差，这主要归因于病因差异。美国患者术后活动水平较高，聚乙烯磨损速度更快，这可能导致 THA 术后 10 年左右牙槽窝松动率增加。美国系列在≥9年的随访中股骨翻修率较高，这主要归因于该系列中较低的管扩张指数。
Primary Charnley total hip arthroplasties (THAs) followed for 10 to 20 years were compared between an American (183 sockets and 178 femoral prostheses) and a Japanese (145 sockets and 148 femoral prostheses) series, each performed by a single surgeon at a single hospital using similar techniques. The primary etiology was developmental dysplasia of the hip (70%) in the Japanese series and primary osteoarthrosis (50%) in the American series. Radiographic socket survival was inferior in the Japanese series at 4- to 11-year follow-up, which was attributed mainly to the etiologic difference. The American patients had higher levels of postoperative activity and developed more accelerated polyethylene wear, which may lead to an increased loosening rate of sockets > or = 10 years after THA. The American series had higher rates of femoral revision at > or = 9 years follow-up, which was attributed mainly to lower canal flare indices in that series.
