Bold values indicate statistical significance at P < .05.
AOT = angle of the talus, ATFL = anterior talofibular ligament, CI = confidence interval, OR = odds ratio, PTFL = posterior talofibular ligament, TAL = the length of the trochlea tali arc, TAS = length of tibial articular surface, TMM = the angle between the tibial axis and medial malleolus.
