摘要:

人工關節是替代病變或損傷關節的植入性假體，除了應滿足生物相容性要求外，必須具有足夠的耐磨損性能、力學性能和抗氧化性能等。超高分子量聚乙烯因其自身優良的理化性能而被廣泛應用于人工關節置換。本文綜述了國內外為提高超高分子量聚乙烯人工關節植入體綜合性能而對材料進行改性處理的各種方法，包括輻照交聯、熱處理、加入抗氧劑等，最后總結了通過調控流動場誘導形成自增強結構來改善人工關節植入體力學性能的最新進展，并展望了超高分子量聚乙烯人工關節高性能化的未來研究方向。

Abstract:

Artificial joints acting as implants to replace diseased or injured human joints should possess good wear resistance, mechanical properties and oxidative stability besides biocompatibility. Ultra high molecular weight polyethylene (UHMWPE) has been widely used as artificial implants because of its excellent chemical and physical properties. This review article summarized methods for modifying the comprehensive properties of UHMWPE implant, including radiation cross-linking, thermal treatment, adding antioxygen. The review also summarized latest progress on improving mechanical properties of the implant through inducing formation of self-reinforced structure in flow field, and also prospected the research direction of high performance artificial joint in the future.

Keywords: ultra-high molecular weight polyethylene; artificial joint; wear resistance; oxidation resistance; mechanical properties
