Total hip arthroplasty is one of the most successful operations medicine can offer. As more patients undergo total hip arthroplasty the revision burden increases proportionately. This is a cohort study of the Arcos Modular Femoral Revision System.
The primary outcome was rerevision of the femoral component. Secondary outcomes include complications and radiological and clinical outcomes over 5 years.
A total of 74 patients were recruited, and the femoral survival rate was 100% at 5 years with 12 censorships. A total of 31 patients were given Proprosky 3/4 preoperatively. Eleven patients underwent further procedures; however, no femoral components were revised. Kaplan-Meier analysis was performed by a biostatistician. Patients demonstrated a consistent and sustained improvement in Harris hip score, Oxford hip score, and EQ-5D. Radiological review revealed minimal and stable lysis around the femoral components.
The ARCOS Modular Femoral Revision System was designed to offer a range of options to allow femoral bone stock preservation and avoiding conversion to an endoprosthetic and seems to be effective in the medium term.
全髋关节置换术是医学所能提供的最成功的手术之一。随着越来越多的患者接受全髋关节置换术，翻修负担也相应增加。这是一项关于Arcos模块化股骨翻修系统的队列研究。
主要结局是股骨组件的再次翻修。次要结局包括并发症以及5年期间的放射学和临床结局。
共招募了74例患者，5年时股骨生存率为100%，有12例失访。共有31例患者术前接受了Proprosky 3/4。11例患者接受了进一步手术；然而，没有股骨组件被翻修。由生物统计学家进行Kaplan-Meier分析。患者的Harris髋关节评分、牛津髋关节评分和EQ-5D均持续且稳定地改善。放射学检查显示股骨组件周围的骨溶解轻微且稳定。
ARCOS模块化股骨翻修系统旨在提供一系列选择，以保留股骨骨量并避免转换为内置假体，且在中期似乎有效。
