Motion analysis of human cadaver knee-joints using anatomical coordinate system

Large standard deviation can be observed during the analysis of the kinematical functions which describe the motion of the knee-joint. Screening the previous large number of published results concerning to the knee motion it seemed that they are scattered, therefore it can be regarded as unreliably. In our experiments anatomical coordinate system recommended by VAKHUM project was used in favor to reduce standard deviation. Setting up the anatomical coordinate system in its special anatomical points are very uncertain. A protocol was settled for the orientation of the anatomical points and for the anatomical coordinate system. Experiments were performed on five cadaver knees using the new protocol. The measurements were analyzed which has proved that the method offers a better accuracy. DOI:  10.17489/biohun/2010/1/12
