The effects of gamma radiation and low temperature hydrogen peroxide gas plasma (HPGP) sterilization on structure and cyclic mechanical properties were examined for orthopedic grade ultra-high-molecular-weight polyethylene (UHMWPE) and compared to each other as well as to no sterilization (control).
## Abstract The impact of femoral head surface roughness on wear of Ξ³βirradiation sterilized (3 MRad in nitrogen, crosslinked) and nonsterilized (not crosslinked) UHMWPE acetabular cups has been evaluated. Gravimetric wear testing was performed in a hip joint simulator for 2 Γ 10^6^ cycles. CoCrMo
The aim of this work is to understand the role of chemical and radiation induced crosslinking on the fatigue crack propagation resistance of medical grade ultrahigh molecular weight polyethylene (UHMWPE). In recent years, the need to improve the tribological performance of UHM-WPE used in total join
The adverse biological response to ultra-high molecular weight polyethylene (UHMWPE) wear debris in total joint replacement warrants the need for the material's improved wear resistance. The reaction of oxygen with radiation-induced free radicals within UHMWPE leads to oxidative degradation of the m
Medical products sterilized in a gamma processing facility are given an absorbed dose greater than or equal to a specified minimum dose chosen to achieve a required sterility assurance level. Because of the dose variation in the product volume, most of the product receives a dose greater than the mi
