Influences of Varus Tilt on the Stresses in Human Prosthetic Knee Joint

Abstract:

In this paper the effects of varus tilt on contact stresses in the three components of total knee prostheses using 3D finite element analysis were investigated. Using Ansys simulation environment, six complex virtual models of human knee joint–prosthesis assembly obtained for six different varus tilts which increase from 176^o to 191^o, with an increment of 3^o have been subjected to finite element analysis in order to obtain the stress maps and total displacements maps.
