In the international literature there are only few publication about the normal biomechanical parameters of the lower limb examined prospectively in healthy population. The goal of our study to determine 15 anatomical and biomechanical parameters of the lower limb using 3D reconstruction based on upright, stereo radiographs in young, healthy volunteers.
