Abstract: The aim of this research was to study the distribution of contact stresses in prosthetic knee joint made up of polyethylene material. Commercially available software ANSYS 18.1 used in numerical experimental. The effect of the sagittal radius, flexion angle and external load on stresses in the knee joint were investigated in numerical experiments. The compare results for experimental method and FEA method.
So Overall, this investigation gives a rule to creation of prosthetic knee joint at sensible expense with better arrangement of sagittal radius and flexion angle to withstand the loads under different circumstances.

Keywords: Knee joint, tibia, femur, polariscope, sagittal radius, flexion angle.
