Abstract Around 500,000 total hip and knee arthroplasties are performed each year in the United States, with a comparable number performed annually throughout the rest of the world. Since its development in the 1960s, contemporary total joint arthroplasty has proven to be extremely successful in alleviating pain and restoring joint function. However, for a minority of patients, mechanical and biological sequelae emanating from the breakdown of the ultra-high molecular weight polyethylene (UHMPWE) bearings limit the longevity of the procedures.

Abstract Advances in design, materials, and fixation have increased the longevity of total joint replacements and significantly reduced the incidence of mechanical failure or loosening of implant components. Wear of the ultra-high molecular weight polyethylene (UHMWPE) bearing material used in most implants is now among the most important problems in total joint replacement. Wear tests in joint simulators are the gold standard for evaluation of wear resistance and are performed on a routine basis in many research laboratories. Physical wear testing, however, is labor intensive and time consuming. Numerical wear simulations have been developed and applied to the hip joint to evaluate adhesive wear of polyethylene liners [1,2]. The purpose of this project was to develop a general adhesive wear simulation applicable to any articulating joint with arbitrary geometry and subject to arbitrary relative motion. Validation of the model was established through application to the patellofemoral joint of a total knee replacement.
