the patellofemoral joint and the total knee replacement

Abstract

The biomechanical investigation of the entire knee joint is essential in understanding the joint function and interaction between various components in both intact and perturbed condition. In the most clinically successful cases many patients treated by total knee replacement (TKR) cannot achieve normal joint function over time.The knee joint is the most complicated joint in the human body. The model of the knee joint with total knee replacement is based on the finite element method. The attention of present study was focused on the patellofemoral joint and the patella tracking with different Q-angle and condylar twist angle. The patellofemoral joint is frequently the source of the knee anterior pain related to disturbances in normal tracking.
