This study investigated the influence of modeling which was changed meshing style, accuracies of contour shape, material properties and the size of finite elements in order to simulate mechanical behavior during impact loading conditions for biomechanical simulation. Three-dimensional finite element models of a human knee joints were constructed which were consisted of cortical, cancellous bone, articular cartilage and meniscus. An Impact loading were performed to the models and the behavior of the models were observed. Simulation results showed that the shape fidelities and the element aspect were more effective to keep accuracy of time dependent behaviors of model than the amount of element and material nonlinearities.
