Recently, a static model of the knee featuring a spherical approximation of the contact surfaces has been defined by a sequential approach, in order to generalize a kinematic model of the joint passive motion. The aim of this study is to define a more sophisticated static knee model with articular surfaces which accurately reproduce the anatomical ones. The motion of the new model is compared, under several loading conditions, with the motion of the knee when the same loads are applied and with the motion of the previous static model. Although some improvements could be achieved by a proper optimization of the model parameters, the model is able to replicate the behavior of the human knee under both passive and loaded conditions.

Abstract

Recently, a static model of the knee featuring a spherical approximation of the contact surfaces has been defined by a sequential approach, in order to generalize a kinematic model of the joint passive motion. The aim of this study is to define a more sophisticated static knee model with articular surfaces which accurately reproduce the anatomical ones. The motion of the new model is compared, under several loading conditions, with the motion of the knee when the same loads are applied and with the motion of the previous static model. Although some improvements could be achieved by a proper optimization of the model parameters, the model is able to replicate the behavior of the human knee under both passive and loaded conditions.
