Abstract
Recent joint surgery studies reveal increased revisions and resurfacing of the metal on metal hip joints. Metal on metal hip implants were developed more than thirty years ago and their application has been refined because of availability of advanced manufacturing techniques and partly by advancements in material science and engineering. Development of composite materials may provide greater durability to metal-on-metal hip implants .This review article is a study of the latest literature of metal-on-metal hip implants and its various modeling techniques. Numbers of methods are used for convergence and numerical solution to investigate the performance of metal-on-metal hip implant for accurate stable solution. This paper presents analysis done by various researchers on metal-on-metal hip implants for wear, lubrication, fatigue, bio-tribo-corrosion, design, toxicity and resurfacing. After in vivo and in vitro studies, it is found that all these methods have limitations. There is a need of more insight for lubrication analysis, geometry of bearings, materials and input parameters. The information provided in this work is intended as an aid in the assessment of metal-on-metal hip joints.
