In these recent trends, over 70% of osteosarcoma affects large bones in the lower extremity (femur and tibia). Most of the cases are reported for children below 20 years, and require surgery involving prosthetic reconstruction. so, the development of Artificial Prosthesis is the Prominent Solution for this great Cause. Osteosarcoma is an aggressive malignant neoplasm arising from primitive transformed cells of mesenchymal origin that exhibit osteoblastic differentiation and produce malignant osteoid. It is the most common histological form of primary bone cancer. Before implant of the Prosthesis it should be tested nearly 10 million cycles to withstand 10 years of prosthetic life in the human body. Knee Simulator is the Testing Machine which helps in testing of this artificial Prosthesis by achieving various motions of the knee joint such as Flexion, Extension , Tibial Rotation , etc by applying the Artificial load for the joint constantly. In this Paper the Flexion – Extension motion of the Knee joint has been tested from 0 to 60° with the constant load. this simulator has been designed and developed in such a way that it can withstand the loads and vibrations during testing. And this hardware is engaged with the computer control using the LABVIEW Software
