The aim of this study was to evaluate the development of the worldwide survival rate of primary total hip arthroplasty (THA). The hypothesis was that survival improved over the last decade in worldwide arthroplasty registers.
THA registers were screened in 2022 and compared between different countries with respect to the number of primary implantations per inhabitant, age, fixation type, and survival rate, and compared to similar data from 2009. The data from these reports were analyzed in terms of number, age distribution, and procedure type of primary THAs. Survival curves and a comparative analysis with respect to the development over time were calculated.
We identified nine hip arthroplasty registers that contained sufficient data to be included. A large variation was found in the annual number of primary THA implantations per inhabitant, with more than the factor 4 for all age groups across regions. The procedure type varied strongly as well, e.g. in Sweden, 50% were cemented THAs, whereas in Emilia-Romagna (Italy), 96% of THAs were implanted cementless. We found an improved survival rate of 5%, with 90% of survival after 15 years in the cohorts from 2021 compared to 85% in the cohorts from 2009.
The present study revealed a significant improvement in the survival of THA in worldwide arthroplasty registers within different countries and regions over the period of one decade. We believe that it is safe to state that the success of THA is still rising with respect to this main outcome.
本研究旨在评估全球初次全髋关节置换术（THA）生存率的发展情况。假设是在过去十年中，全球关节置换登记处的生存率有所提高。
2022年对THA登记处进行筛选，并就每个居民的初次植入数量、年龄、固定类型和生存率在不同国家之间进行比较，并与2009年的类似数据进行比较。对这些报告中的数据按照初次THA的数量、年龄分布和手术类型进行分析。计算生存曲线以及关于随时间发展的比较分析。
我们确定了九个包含足够数据可纳入的髋关节置换登记处。发现每个居民每年初次THA植入数量存在很大差异，各地区所有年龄组的差异超过4倍。手术类型也有很大差异，例如在瑞典，50%是骨水泥型THA，而在意大利艾米利亚 - 罗马涅，96%的THA是无骨水泥植入。我们发现生存率提高了5%，2021年队列中15年后的生存率为90%，而2009年队列中为85%。
本研究表明，在十年期间，不同国家和地区的全球关节置换登记处中THA的生存率有显著提高。我们认为可以有把握地说，就这一主要结果而言，THA的成功率仍在上升。
