Although hip, knee and other orthopedic implants are well-established prostheses, much remains to be understood about how these implants wear in use. This important book summarizes the wealth of recent research in this area and its implications for implant and joint design.? After an introductory overview, the book reviews the causes and prevention of implant wear.? Part one discusses fundamental issues such as tissue response to wear, the anatomy and biomechanics of hips and knees as well as the materials and design issues they raise for hip, knee and other types of orthopedic implants. Part two considers wear phenomena in a range of materials, including ultra-high molecular weight (UHMWPE), metal and ceramic joints. It also covers surgical and other factors influencing wear, as well as ways of detecting, analyzing and predicting implant wear and failure.
