Knee joint simulator and In particular to a knee joint simulator system which would be cost effective, simple to manufacture and use. Importantly, the simulator of the invention Involves Tibial Implant (TB) and Femoral Implant (FM) wherein the Femoral Implant (FM) Is maintained stationary while the Tibial Implant (TB) Is adapted for motion with respect to the Femoral Implant (FM) mimicking usual human Joint movement The tibial movement is achieved involving a an runner (CM) and stepper motor connected at an end part of the Tibia and an hydraulic actuator means (AM) connected to the other end part of Tibia, a Control Panel (CP) operatively connected to a Computer System (CS) for generating controlled simulated motion for required testing of Implants. The simulator takes In account the load and the displacement time histories and simulates In the best possible manner the forces that occur at the knee joint due to physiological conditions during walking and running Involving the use of hydraulic actuators. Advantageously the simulator utilizes bone model and simulates the real situation closely. The simulator is specifically adapted to provide extremely cost effective testing of implants especially involving biocompatible materials. (FIG. 1)
