In recent years, the use of a collared cementless femoral prosthesis has risen in popularity. The design intention of collared components is to transfer some load to the resected femoral calcar and prevent implant subsidence within the cancellous bone of the metaphysis. Conversely, the load transfer for a cemented femoral prosthesis depends on the cement-component and cement-bone interface interaction. The aim of our study was to compare the three most commonly used collared cementless components and the three most commonly used tapered polished cemented components in patients aged ≥ 75 years who have undergone a primary total hip arthroplasty (THA) for osteoarthritis (OA).

基于登记的研究，比较老年骨关节炎患者全髋关节置换术中骨水泥股骨假体与带环非骨水泥股骨假体的生存率。

近年来，带环非骨水泥股骨假体的使用越来越受欢迎。带环组件的设计目的是将一些负载转移到切除的股骨距，并防止植入物在干骺端的松质骨内下沉。相反，骨水泥股骨假体的载荷传递取决于骨水泥-组分和骨水泥-骨界面的相互作用。我们研究的目的是比较 75 岁以上因骨关节炎 (OA) 接受初次全髋关节置换术 (THA) 的患者中三种最常用的带环非骨水泥假体和三种最常用的锥形抛光骨水泥假体。
