## Abstract The preconditioned stress relaxation behavior of irradiated ultraβhigh molecular weight polyethylene (UHMWPE), a commonly used bearing surface in total joint replacements (TJR), was modelled in uniaxial compression at 37Β°C. Twenty cylindrical specimens (10 mm dia. Γ 27 mm length) were m
## Abstract Oxidative degradation of ultraβhigh molecular weight polyethylene (UHMWPE) attributed to sterilization by gammaβradiation in the presence of air has been cited as one of the major causes of premature wear in total joint arthroplasty. For example, in retrieved UHMWPE tibial bearings, not
