In daily activities, human have impulsive external force during walking and jumping. In this study, two kind of human knee finite element models, which were assumed standing and flexion conditions. A 300N impact load applied to the proximal femur of the finite element model and the temporal changes of the displacement and the stress distribution were observed. In this result of upstanding simulation, the temporal changes of the lateral displacement between the femoral condyle and the tibial platau was increased to 2.1mm. In constrast using flextion model, the high maximum principal stress concentration was observed around the patella ligament compared with the upstanding one.
