The aim of this study was to establish a three-dimensional finite element mesh model to investigate the biomechanical responses of the patellofemoral joint. Based on the real geometry caught from the computer tomography, the basic kinetical and kinematical behavior of the patellofemoral joint was analyzed during flexion. The flexion loading was simulated as quasi-static displacement loading which obtained from three dimensional motion analysis. The biomechanical influences of the anterior displacement of the tibial tuberosity surgical operation was also investigated. The results of this study showed that maximum contact stresses of patellofemoral joint occurred on the lateral side, which might be the reason for cartilage wearing. The stress of the cartilage was decreased as the anterior displacement of tibial tuberosity was increased, but the contact area of the patellofemoral joint also was reduced which might cause unstable during flexion.
