| Tartalmi kivonat: | Different authors are dealing with description of motion components of human knee joint. The relative motion between femur and tibia realized by knee joint is ensured by complicated condyle surfaces and ligaments. Main part of authors focus merely on rotational displacement of human knee joint such as flexion-extension, abduction-adduction, tibial rotation. In order to achieve implanted prostheses we have to recognize not only the rotational but also translational kinematical parameters of human knee joint. Authors of this paper for description of motion of knee joint joined coordinate-systems on the basis of anatomical landmarks to the femur and tibia moreover joined a threecylindrical mechanism as mechanical model to the axes of coordinate-systems. In 2nd phase authors determined the six independent kinematical parameters of tibia compared to the fixed femur during flexion and extension. The experimental examinations were carried out on cadaver knees. The positioning was tracked by optical positioning appliance. |
