Abstract

In this paper, using 3D finite element method and starting from the virtual model of the human knee joint-prosthesis assembly, we investigate the effects of antero-posterior tibial slope on contact stresses in the three components of total knee prosthesis. Using AnsysWorkbench15.07 software, the stress and displacements maps are obtained for knee-prosthesis assemblies and for their components, considering two loading force: 800N and 2400N and two cases of prosthetic knee varus slope: 176o and b) 191o. For each prosthesis-knee assembly and for each considered force, two variants of antero-posterior tibial slope were considered: 00 and 50.
