The material selection used for knee implantation is important for successful and long usage of knee prosthesis. There are different types of materials that are used for knee implantation like cobalt-chromium alloys, titanium, and its alloys, tantalum, polyethylene, and zirconium. The material should have good mechanical properties i.e. high wear and fatigue strength and less corrosion resistance while rubbing of femur component of the knee implant on the tibial surface. So, in this paper efforts are made to generate a 3D CAD model of femur and tibia component using CREO parametric 2.0 according to 2D drawing created from CT scan data of the patient and it is imported in ANSYS 17 for evaluation of stress, deformation, and contact pressure. The objective of this paper is to find out the suitable implant material that shows less von-misses stress and deformation under the action of applied load in static conditions. The femur component is also modeled using different flexion angles and its study has been done using different implant materials.
