Loading, boundary conditions and analyses: a Loading and boundary conditions of the simplified loading models. b Cross section of the contralateral cortex and path to check the stresses in the contralateral cortex; B1 and B2 were the starting point and the ending point of the path B1B2 that was chosen and on which the stress distribution was determined. c Cross section where section forces and moments were determined in order to highlight the influence of muscle forces. d Cross section passing through the transepicondylar axis that was defined in order to calculate the section forces in the knee joint. e The three weak springs (ab, cd and ef) that were used to quantify the micromovements of the wedge
