  1. Results were presented if the correlations were statistically significant (p < 0.05). See Table 1 and Fig. 5 for the regions of the distal tibia and fibula. The regions of the talus were defined in our previous study8: region 2, the most superior point of the medial margin of the trochlea; region 3, the most posterior point of the medial margin of the trochlea; region 4, the midpoint of the anterior margin of the trochlea; region 7, the most anterior point on the lateral margin of the trochlea; region 11, the most inferior point of the lateral articular facet. rs, Spearman’s rank correlation coefficient.
