Abstract
The relationship between contact stress in ultra high molecular weight polyethylene (UHMWPE) tibial components of knee implants and long-term wear behavior was considered. It was found that rougher counterfaces produce larger numbers of smaller particles, while smooth counterfaces produce fewer such particles, but do show evidence of larger platelets. The surface finish of the femoral components was examined and the morphology of the wear debris obtained from testing was compared.
