pathes for comparison
Pathes obtained from the X-ray contours at various degrees of flexion of a healthy knee, were taken as a comparison for each joint tested and replicated in individual designs sketched on a demonstration of the differences observed.
Each of the mechanisms examined, has a different handling and no one comes close to the roto-translational characteristics typical of the knee physiological motion.
Furthermore, for no one device has been found a convincing scientific documentation that would justify the similarity of the trajectory proposal with the physiological movement of the knee itself and in particular the indications that would clarify how to overlay and align the mechanical trajectory with that of the knee.
Here are the main patented devices exposed on market.
