Joint replacement surgery has seen remarkable progress and development in recent years both in prostheses and in surgical technique. A prime concern has been improved durability, for which a major factor is reduction of the polyethylene wear that leads to osteolysis. This book presents an update on the means by which the problems of wear and loosening are being addressed in total hip arthroplasty (THA) and total knee arthroplasty (TKA). Included are chapters on new surgical techniques for difficult cases, nonpolyethylene interfaces for THA, custom hip prostheses and computer-assisted surgery. The text also takes up controversial issues such as posterior cruciate substitution versus retention in TKA. With contributions by specialists in total joint replacement in Asia, Europe and North America, this volume is dsigned as a reference for orthopedic surgeons.
