Bold values indicate statistical significance at P < .05.
AOT = angle of the talus, ATFL = anterior talofibular ligament, AUC = area under the curve, OLT = osteochondral lesions of the talus, PMA = plafond–malleolar angle, PTFL = posterior talofibular ligament, TAL = the length of the trochlea tali arc, TAS = tibial articular surface, TMM = the angle between the tibial axis and medial malleolus.
