The peak knee abduction angle during stance phase was significantly correlated with both age at menarche (r = 0.45; p=.002) and base of support (r = 0.38; p=.01). Peak knee abduction moment during stance, however, was not significantly correlated with either age at menarche (r = -0.16; p=.30) or base of support (r = -0.17; p=.25). Earlier menarche and wider base of support were therefore associated with a more valgus peak knee frontal plane angle during stance.
