... We hypothesized that oxidation would influence the resistance to fatigue crack initiation and propagation of Ultra-High molecular weight polyethylene (UHMWPE). We subjected tibial insert surrogates (ram extruded GUR 1050) to accelerated aging protocols following ASTM F 2003-00 (14, 21 and 28...

...%. There were also noticeable changes in the modulus with decreases of 40–70% and for one product, an increase of 43% after 8000 hours of accelerated aging. It is surmised that modulus decreases are due to chain scission; however, it was not possible to strictly verify this from the analytical work carried out...
