全髋关节置换术（THA）虽然是治疗终末期髋关节疾病患者的高效手术，但由于手术量的增加以及新技术的引入和广泛使用，其成本越来越高。从1995年至2005年的国家住院患者样本和其他公开来源获得了关于THA手术量和手术成本的数据。研究期间手术量增加了61%。经通货膨胀调整后，使用医疗消费者价格指数，THA植入物的平均销售价格上涨了24%。在研究期间，THA植入物的销售价格占总手术成本的百分比从29%增加到60%。在美国，THA成本的增加是手术量增加和THA植入物成本增加的结果。没有与使用新植入物技术相关的长期结局研究，短期结果与前几代THA植入物相似。这项研究强调了美国全关节置换术注册和骨科新技术的临床和经济分析的必要性。
Total hip arthroplasty (THA), though a highly effective procedure for patients with end-stage hip disease, has become increasingly costly, both because of increasing procedure volume and because of the introduction and widespread use of new technologies. Data regarding procedure volume and procedure costs for THA were obtained from the National Inpatient Sample and other published sources for the years 1995 through 2005. Procedure volume increased 61% over the period studied. When adjusted for inflation, using the medical consumer price index, the average selling price of THA implants increased 24%. The selling price of THA implants as a percentage of total procedure costs increased from 29% to 60% during the period under study. The increasing cost of THA in the United States is a result of both increased procedure volume and increased cost of THA implants. No long-term outcome studies related to use of new implant technologies are available, and short-term results have been similar to those obtained with previous generations of THA implants. This study reinforces the need for a US total joint arthroplasty registry and for careful clinical and economic analyses of new technologies in orthopedics.
