Total hip arthroplasty is a short-term solution for replacing a damaged hip joint with synthetic biomaterials. Total hip arthroplasty comes in two flavors: single and dual mobility. Mechanical and biological factors may degrade the quality of biomaterials over time. This may lead to implant failure and second surgical treatment. Wear is the crucial element leading to damaged bone and debris release throughout the body over time. Running-in is the initial wear phase between two surfaces before the steady-state phase. The stage of running-in is critical for understanding hip joint wear. Running-in and wear behavior have been extensively studied in single-mobility total hip arthroplasty, but aseptic loosening is the leading reason for restoration in arthroplasty registries. This paper seeks to summarize running-in behavior on single mobility hip implants, emphasizing its key aspects and recent developments.
全髋关节置换术是用合成生物材料替代受损髋关节的短期解决方案。全髋关节置换术有两种类型：单动和双动。机械和生物因素会随着时间的推移而降低生物材料的质量。这可能导致植入物失效和二次手术治疗。磨损是导致随着时间的推移，受损的骨头和碎片在体内释放的关键因素。磨合是两个表面在稳定阶段之前的初始磨损阶段。磨合阶段对于理解髋关节磨损至关重要。单动全髋关节置换术中已经对磨合和磨损行为进行了广泛研究，但无菌性松动是关节置换登记处修复的主要原因。本文旨在总结单动髋关节植入物的磨合行为，强调其关键方面和最新进展。
