Cross-linked Polyethylene Engineered for TKA
Introduction It is well known that the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) improves in proportion to the crosslinking irradiation dose. It is also well known that the mechanical properties and oxidative stability of UHMWPE are affected by the irradiation dose, resin type, and post-irradiation heat treatment, among others factors. Therefore, careful consideration...
متن کاملUphill diffusion in multicomponent mixtures.
Molecular diffusion is an omnipresent phenomena that is important in a wide variety of contexts in chemical, physical, and biological processes. In the majority of cases, the diffusion process can be adequately described by Fick's law that postulates a linear relationship between the flux of any species and its own concentration gradient. Most commonly, a component diffuses down the concentrati...
متن کاملWear of moderately cross-linked polyethylene fixed bearing knee replacements
Cross-linked polyethylene has been explored as an alternative to conventional polyethylene in total joint replacement in order to reduce wear volume and decrease failure through polyethylene wear debris induced osteolysis [1]. Due to the demands of a total knee replacement, moderately cross-linked polyethylene is recommended to retain mechanical properties [2]. This study aims to investigate th...
متن کاملComparison of cross-linked polyethylene materials for orthopaedic applications.
Cross-linked polyethylenes are being marketed by orthopaedic manufacturers to address the problem of osteolysis caused by polyethylene particulate wear debris. Wear testing of these cross-linked polyethylenes in hip simulators has shown dramatic reduction in wear rate compared with standard ultrahigh molecular weight polyethylene, either gamma irradiated in air or nitrogen - or ethylene oxide-s...
متن کاملInvestigating the Effect of Using Cross-Linked Polyethylene Waste as Fine Aggregate on Mechanical Properties of Hot Mix Asphalt
Cross-linked polyethylene (XLPE) is an appropriate insulating material for high-voltage cables which has been widely used as electrical cable coating. In this study, Crushed XLPE wastes with different volume percentages (25, 50, and 75%) were used in hot mix asphalt (HMA) as a substitute for fine aggregates remained on sieve no. 8 whose size varies from 1.18 to 2.36 mm. The dynamic stiffness (i...
