摘要全髋关节手术是缓解因关节病变或损伤引起的疼痛和不适的有效方法。然而，在大多数情况下，这些接头的寿命是有限的。失败的主要原因是骨溶解(骨吸收)。众所周知，骨溶解的一个重要原因是人体对聚乙烯磨损颗粒的免疫反应，从而导致传统的金属或陶瓷超高相对分子质量聚乙烯关节松动和失效。为了避免这种情况，人们对金属对金属的连接重新产生了兴趣。本文的目的是回顾在不同实验室进行的研究，以确定新一代金属对金属全髋关节置换术的摩擦学性能。这些类型的关节提供了一种潜在的解决方案，以提高假体髋关节系统的寿命；然而，由于金属离子释放的影响，可能会出现问题，到目前为止，还不完全清楚。
Abstract Total hip surgery is an effective way of alleviating the pain and discomfort caused by diseased or damaged joints. However, in the majority of cases, these joints have a finite life. The main reason for failure is osteolysis (bone resorption). It is well documented that an important cause of osteolysis, and therefore the subsequent loosening and failure of conventional metal- or ceramic-on-ultra-high molecular weight polyethylene joints, is the body's immunological response to the polyethylene wear particles. To avoid this, interest has been renewed in metal-on-metal joints. The intention of this paper is to review the studies that have taken place within different laboratories to determine the tribological performance of new-generation metal-on-metal total hip replacements. These types of joint offer a potential solution to enhance the longevity of prosthetic hip systems; however, problems may arise owing to the effects of metal ion release, which are, as yet, not fully understood.
