The aim of this study was to compare the migration of the femoral component, five years postoperatively, between patients with a highly cross-linked polyethylene (HXLPE) insert and those with a conventional polyethylene (PE) insert in an uncemented Triathlon fixed insert cruciate-retaining total knee arthroplasty (TKA). Secondary aims included clinical outcomes and patient-reported outcome measures (PROMs). We have previously reported the migration and outcome of the tibial components in these patients.

使用高度交联或传统聚乙烯插入物的全膝关节置换术中非骨水泥股骨组件的五年迁移：使用放射立体分析的盲法随机对照试验。


本研究的目的是比较非骨水泥铁人三项固定十字韧带中使用高度交联聚乙烯 (HXLPE) 插入物的患者与使用传统聚乙烯 (PE) 插入物的患者术后 5 年股骨假体的迁移情况。保留全膝关节置换术（TKA）。次要目标包括临床结果和患者报告的结果测量（PROM）。我们之前曾报道过这些患者的胫骨组件的迁移和结果。
