Bae JY, et al. - Researchers explored the association between pain and angular change of the lower extremity in genu varus individuals. This study examined standing whole-lower-leg plain radiographs of 127 legs (77 individuals) with > 4° of genu varum. At the ankle, forefoot, and hindfoot, pain was evaluated separately. Knee, ankle, and subtalar joint angles were assessed. Individuals were categorized into 3 groups according to the degree of lower leg angular imbalance (group 1, mild; group 2, moderate; group 3, severe). The results of this study indicated that an unbalanced lower extremity with genu varum was correlated with multiple foot and ankle pain, and the subtalar joint played a primary role in compensation for genu varum deformity.
