Investigation of Wear and Wear Particles from Shelf-Aged Crosslinked UHMWPE under Different Contact Pressures

The wear particles generated from ultra-high molecular weight polyethylene (UHMWPE) are considered as the main reason to cause the osteolysis and aseptic loosening related to the failure of the artificial joint. This paper investigated the effect of radiation dose and contact pressure on the wear ra...
