Methodological workflow to determine the position of the knee in exact 0°, 30°, 60° and 90° of flexion. (a) The 3D osseous configuration extracted from the MRI scans and the predicted meniscal positions in 4 different configurations of knee flexion served as the input for the PPSA model. The calculated flexion angles were added. (b) The development of a subject-specific PPSA model allowed to continuously describe osseous and meniscal position between 0° and 90° and to extract the exact 0°, 30°, 60° and 90° positions.
