Abstract
A method of manufacturing an articulating bearing surface for use in an orthopaedic implant uses a supply of ultra-high molecular weight polyethylene particles which are irradiated with sufficient radiation energy to crosslink at least a portion of the ultra-high molecular weight polyethylene. The irradiated particles are then formed into an orthopaedic bearing surface.
