Abstract

Screening of candidate materials by simple and affordable testing machines has been part of the development of orthopedic bearings since the 1970s. The promising candidates would then be tested in a joint simulator and in vivo testing of the most promising materials would follow. However, there is uncertainty about the capability of pin-on-disk (POD) testers to realistically simulate clinically relevant wear mechanisms with repeatability across different laboratories. We describe the factors, conditions, and potential pitfalls involved in the setup of POD testing for wear assessment of UHMWPE and provide a quick review and critique of the international standard testing methodologies of POD testing relevant to UHMWPE.
