Our research group has developed a new type of knee prosthesis capable of making deep knee flexion and designated it as CFK (Complete Flexion Knee). In order to assess the performance of CFK, we have set up various kinds of simulation/experimental projects, such as a mathematical model analysis, a photoelastic analysis and FEM analysis. The objective of this study is to introduce the force acting on the knee joint and the lower limbs' muscle forces at deep knee flexion to carry out the above-mentioned projects. A 2D mathematical model was used. Double leg ascending motions from deep squatting with heel rising were studied for 10 healthy male subjects. The results demonstrated that both the normal force acting on the knee joint and the quadriceps force became maximum when knee flexion angle became 130°. Both of their maximum value were proportional to the subject's body weight.
