UHMWPE for TJR is usually modified by irradiation and thermal treatment to increase wear resistance. We modified UHMWPE in three ways, differing in radiation dose-rate and/or atmosphere during irradiation. Using a number of rheological measurements, morphological investigations and wear testing experiments we proved that higher dose rates at inert atmosphere lead to higher crosslinking and higher wear resistance of UHMWPE.
