Measurements of the angles and lengths of the ligaments and original coordinate planes with squares. Distances between the center points of the tibial and fibular insertion sites of the (a) anterior inferior tibiofibular ligament (AITFL) and (b) posterior inferior tibiofibular ligament (PITFL). The angles were formed between a horizontal line and the line between the center points of the tibial and fibular insertions of the AITFL (α) and PITFL (β). The maximum medial–lateral distance between the medial tibial cortical line and most of the lateral fibular cortical line in the true anterior view of the three-dimensional images was used as a standard (100%), and coordinate grids fitting the medial and lateral condyles on the three-dimensional images were created. The x-axis was defined as the middle of the coordinate grid (the horizontal line of the tibial plafond). The y-axis was defined as the medial perpendicular line on the grids. The origin of the coordinate axes was the point of intersection between the y-axis and the horizontal line of the tibial plafond
