On the Effect of Friction on Tibiofemoral Joint Kinematics

The effect of friction on nonlinear dynamics and vibration total knee arthroplasties is yet to be investigated understood. This research work aims at studying the influence dynamics, friction-induced vibration, damage tibiofemoral joints. For this purpose, a spatial dynamic model developed using an asymmetric elastic accounting for joint ligaments penalty contact compute normal stresses in while detection treated such that associated computational time reduced. Several models are considered embedded estimate tangential forces joint. External loads moments, due presence all soft tissues, e.g., muscles hip-joint reaction forces, applied femoral bone determined musculoskeletal approach. In post-processing stage, damage, i.e., wear creep, estimated three empirical creep formulation, respectively. addition, FFT analysis performed evaluate likely Mesh density methodology assessed against outcomes available literature. It can concluded influences not only tribology, but also joint, take place when coefficient increases.
