聚乙烯衬垫的磨损是全膝关节置换术(TKA)失效的主要原因,因此磨损的测量与评估是人工膝关节研究的关键内容之一。聚乙烯衬垫磨损的测评方法有很多,如目测观察分级法等定性方法,可用于观察和确定磨损的程度及类型;而重量分析法、坐标测量仪(CMM)以及micro-CT磨损测量等定量方法,可对质量、体积磨损,以及磨损分布等进行定量测评。该文介绍了聚乙烯衬垫磨损的主要测评技术的原理、特点及研究进展,并分析了这些测评方法中存在的问题和不足。
聚乙烯襯墊的磨損是全膝關節置換術(TKA)失效的主要原因,因此磨損的測量與評估是人工膝關節研究的關鍵內容之一。聚乙烯襯墊磨損的測評方法有很多,如目測觀察分級法等定性方法,可用于觀察和確定磨損的程度及類型;而重量分析法、坐標測量儀(CMM)以及micro-CT磨損測量等定量方法,可對質量、體積磨損,以及磨損分佈等進行定量測評。該文介紹瞭聚乙烯襯墊磨損的主要測評技術的原理、特點及研究進展,併分析瞭這些測評方法中存在的問題和不足。

Wear of polyethylene (PE) tibial inserts is a significant cause of implant failure of total knee arthroplasty (TKA). PE inserts wear measurement and evaluation is the key in TKA researches. There are many methods to measure insert wear. Qualitative methods such as observation are used to determine the wear and its type. Quantitative methods such as gravimetric analysis, coordinate measuring machines (CMM) and micro-computed tomography (micro-CT) are used to measure the mass, volume and geometry of wear. In this paper, the principle, characteristics and research progress of main insert wear evaluation method were introduced and the problems and disadvantages were analyzed.
