在低速高载荷往复运动条件下表现出优异性能的天然关节，其润滑机制主要是以弹流膜为主，辅以各种辅助润滑机制的自适应多模润滑。而现有的关节假体大多不是在流体膜下工作，而是在混合润滑下工作，这会导致一些摩擦学问题，如松动和磨损。本文综述了近年来自然关节和人工关节润滑机理的研究进展，并对人工关节的润滑与磨损以及人工软骨关节的优化设计等问题进行了讨论。
Natural joints exhibiting excellent performance under reciprocating slow speed and high loading conditions have a prominent lubrication mechanism as an adaptive multimode lubrieation, where elastohydrodynamic fluid film plays the main role supported by various supplimental lubrication mechanisms. In contrast, most of the existing joint prostheses operate not under fluid film but under mixed lubrication, which induces some tribological problems such as loosening and wear. Thus, recent investigations on the lubrication mechanisms in natural synovial joints and total replacement joints are reviewed, and then subjects on lubrication and wear in joint prostheses and optimum design of joint prostheses with artifieial cartilage are discussed.
