The long-term durability of polyethylene lining total hip arthroplasty (THA) mainly depends on periprosthetic osteolysis due to wear particles, especially in young active patients. In hip simulator study, reports revealed significant wear reduction of the alumina ceramic-on-polyethylene articulation of THA compared with metal-on-polyethylene bearing surfaces. However, medium to long-term clinical studies of THA using the alumina ceramic-on-polyethylene are few and the reported wear rate of this articulation is variable. We reviewed the advantages and disadvantages of ceramicon- polyethylene articulation in THA, hip simulator study and retrieval study for polyethylene wear, in vivo clinical results of THA using alumina ceramic-on-polyethylene bearing surfaces in the literature, and new trial alumina ceramic-onhighly cross linked polyethylene bearing surfaces.
聚乙烯内衬全髋关节置换术(THA)的长期耐用性主要取决于磨损颗粒导致的假体周围骨溶解,尤其是在年轻活跃患者中。在髋关节模拟器研究中,报告显示与金属对聚乙烯承重表面相比,THA的氧化铝陶瓷对聚乙烯关节的磨损显著减少。然而,使用氧化铝陶瓷对聚乙烯的THA的中长期临床研究较少,且该关节的报告磨损率各不相同。我们回顾了THA中陶瓷对聚乙烯关节的优缺点、髋关节模拟器研究以及聚乙烯磨损的取出研究、文献中使用氧化铝陶瓷对聚乙烯承重表面的THA的体内临床结果,以及新型试验性氧化铝陶瓷对高度交联聚乙烯承重表面的情况。
