“…Valgus deformation was reported in 19 studies involving 114 patients [4, 7, 9, 12, 19, 28, 34, 35, 37, 38, 45, 49-51, 53-55, 57, 58] and varus deformation in 14 studies involving 34 patients [8,16,21,24,28,30,31,34,35,37,43,53,54,62], often presenting as instability upon valgus and varus stress tests, or a positive Bohler test [52]. Ligamentous laxity and joint hypermobility were reported in 7 studies involving 14 patients [7,19,22,26,32,50,53].…”
