## Abstract Wear rates of orthopaedic polyethylene in 37Β°C water are not very contact stress dependent below 1000 psi (6.9 MPa) but above that level they accelerate substantially. The pressure dependence overall follows an exponential function. Creep in the contact pressure range of 3–17 MPa and ab
