在不同的已发表研究中，高交联聚乙烯（XLPE）髋臼部件的磨损率差异很大。这种差异部分是由于用于测量磨损的不同技术以及测量XLPE关节面相对较低磨损量的固有误差。我们对使用最灵敏的方法（放射立体测量分析（RSA））检查XLPE髋臼部件体内磨损的研究进行了范围审查。 对PubMed、Scopus和科克伦数据库进行了系统检索，以识别使用RSA测量初次全髋关节置换术（THA）中XLPE部件磨损的已发表研究。 18篇文献检查了12个初次THA队列，仅包括2-10年随访时的260例THA。报告的平均或中位近端磨损率范围为0.00 - 0.06 mm/年。然而，由于确定磨损的方式存在差异，因此很难对一些研究进行比较。此外，研究之间RSA方法的差异，例如使用仰卧位或站立位X线片以及使用串珠或无串珠参考节段，可能会限制未来检查患者和植入物变量对磨损率影响的荟萃分析。 该范围审查证实了RSA测量的THA中XLPE的磨损率较低。我们建议提高RSA磨损结果报告的标准化，这将有助于早期识别性能不良的植入物，并能够更好地了解手术和患者因素对磨损的影响。
Wear rates of highly crosslinked polyethylene (XLPE) acetabular components have varied considerably between different published studies. This variation is in part due to the different techniques used to measure wear and to the errors inherent in measuring the relatively low amounts of wear in XLPE bearings. We undertook a scoping review of studies that have examined the in vivo wear of XLPE acetabular components using the most sensitive method available, radiostereometric analysis (RSA). A systematic search of the PubMed, Scopus, and Cochrane databases was performed to identify published studies in which RSA was used to measure wear of XLPE components in primary total hip arthroplasty (THA). 18 publications examined 12 primary THA cohorts, comprising only 260 THAs at 2–10 years of follow-up. The mean or median proximal wear rate reported ranged from 0.00 to 0.06 mm/year. However, differences in the manner in which wear was determined made it difficult to compare some studies. Furthermore, differences in RSA methodology between studies, such as the use of supine or standing radiographs and the use of beaded or unbeaded reference segments, may limit future meta-analyses examining the effect of patient and implant variables on wear rates. This scoping review confirmed the low wear rates of XLPE in THA, as measured by RSA. We make recommendations to enhance the standardization of reporting of RSA wear results, which will facilitate early identification of poorly performing implants and enable a better understanding of the effects of surgical and patient factors on wear.
