@@@@BACKGROUND: Ultra-high molecular weight polyethylene has been used widely for the artificial joint prosthetics due to its excel ent physical and chemical properties, which includes the hip and knee joint in the medicine field. OBJECTIVE: To summarize the progress in the modification and tribological studies of medical ultra-high molecular weight polyethylene in recent years. METHODS: The literatures, regarding to the modification and tribological studies of medical ultra-high molecular weight polyethylene, were searched by a computer in ISI and PubMed databases from 1970 to 2012 as wel as in CNKI, Wanfang and VIP database from 1979 to 2012, respectively. The keywords were “ultra-high molecular weight polyethylene, UHMWPE, artificial joint prosthetics, mechanism of friction and wear, wear debris” in English and Chinese, respectively. The repetitive researches were excluded. RESULTS AND CONCLUSION: The results prove that the abrasive wear, adhesion wear and fatigue wear are the main mechanisms of ultra-high molecular weight polyethylene. Because of its low wear resistance, many methods have been used to enhance its tribological properties, including inorganic fil ing (such as hydroxyapatite, zirconium oxide, carbon black, carbon fiber, carbon nanotubes), and the crosslinking (such as organic silane coupling and variety of ionizing radiations). Moreover, the results demonstrate that the wear resistance of the modified materials was improved to different extents in al kinds of joint simulator environment. This paper also expounds the friction mechanism and some wear means of ultra-high molecular weight polyethylene, such as joint simulator, lubrication system, the measurement and evaluation of wear and wear debris.
