摘　　要：人工关节在服役过程中的磨损主要发生在超高分子量聚乙烯(UHMWPE)关节臼的表面。UH-MWPE的磨擦磨损性能受多因素影响,其中与UHM-WPE对磨的硬质材料(对偶件)表面粗糙度是关键因素之一。综述了近年来在对偶件表面粗糙度对UH-MWPE摩擦磨损性能影响方面的研究工作,结合UHMWPE的磨损机制,重点阐述对偶件表面粗糙度对UHMWPE磨损率、UHMWPE磨屑尺寸和人工关节润滑机制的影响。The wear of artificial joints mainly occurred on ultra-high molecular weight polyethylene acetabular.The friction and wear properties of ultra-high molecular weight polyethylene were affected by many factors,but counterface surface roughness was one of the most important.The ultra-high molecular weight polyethylene wear mechanism was reviewed in this paper.And the effect of counterface surface roughness on ultra-high molecular weight polyethylene wear rate,wear debris size and artificial joints lubrication mechanism were mainly discussed.
