Abstract:

Natural synovial joints provide a range of smooth motions while at the same time take a large amount of load of several times bodyweight even during normal walking. Tribology which deals with the relative motion between two contacting surfaces plays an important role in the normal function of our joints as well as the development of joint diseases. Biotribology of our joints covers friction, wear and lubrication as well as the artificial joint replacements. It is important to understand the lubrication mechanisms of our joints with articular cartilage as the bearing surfaces and synovial fluid as the lubricant in reducing friction and minimising wear. Equally important are the developments of biomaterial combinations for artificial joint replacements to reduce friction and wear and therefore prolong the joint lifetime. Current focuses of artificial joint replacements include developing wear-resistance bearing surfaces, while at the same time providing personalised solutions for different patients.

人体关节提供一系列的光滑运动并且同时承担很大的载荷，即使在日常行走中关节的载荷都可以达到几倍的体重。摩擦学涉及到两个相对表面的运动，因此在理解关节的正常功能以及疾病的发展都起到一个重要的作用。人体关节的生物摩擦学研究包括自然关节和人工关节的摩擦，磨损和润滑。对于自然关节研究的重点是软骨承载表面和关节滑液的润滑机理。同等重要的是研发生物材料的配副从而减低人工关节的摩擦和磨损以便延长假体的寿命。目前人工关节研究的重点是研发低磨损的材料配副，同时提供不同患者的个性化治疗方案。
