Abstract
The failure of the soft UHMWPE (ultra-high molecular weight polyethylene) bearing surface liner in total knee arthoplasty is quite common. We looked at the contact stress which, to a great extent, determines the tribological properties. We have seen, by using the FEM (finite element method) technique, that the average shear stress and contact stress depend on the contour of the mating pair of the metal or ceramic to the polyethylene
