Bio and medical tribology

Research output: Chapter in Book/Report/Conference proceedingChapter


Bio-tribology has achieved great prominence in the last few years as a new interdisciplinary fi eld in which contributions from engineers, medical doctors, biologists, chemists, and physicists are co-ordinated. The main purpose of using a joint prosthesis is pain relief and restoring the joint function. To do this, a suitable material that has an infi nite life is desirable. Material selection and component design are important factors in the performance and durability of total joint replacements but, unfortunately, wear of hip and knee bearings exists and is a signifi cant clinical problem. There is a need not only for more wear-resistant materials but also for concomitant improvements in the design and manufacture of the implant and the operative techniques to minimize the occurrence of wear. Wear simulation is an essential pre-clinical method to predict the mid- and long-term clinical wear behaviour of prostheses, and one of the most important aspects of wear testing is simulation of actual wear conditions.
