The polyethylene stresses at a replaced ankle are dependent on the kinematics of the joint, which in turn are dependent on the implant design, position and orientation of the prosthesis relative to bone and soft tissue tensions.

Abstract
The polyethylene stresses at a replaced ankle are dependent on the kinematics of the joint, which in turn are dependent on the implant design, position and orientation of the prosthesis relative to bone and soft tissue tensions. In order to assess the polyethylene stresses the kinematics of the joint must be accounted for. Previous studies of total knee replacement have shown that explicit FE analysis is able to predict the kinematics and stresses simultaneously. The aim of the present work was develop an explicit FE model of a mobile bearing total ankle replacement able to predict joint kinematics, polyethylene stresses and ligaments forces during walking.
