However, recent research suggests that the difference between a man and a woman’s hip structure may be the most significant reason why women experience more knee injuries. A woman’s wider hips cause her to land in a more “knock-kneed” position – angled in from hip to knee and angled out from knee to ankle - to maintain balance, whereas a man’s legs tend to be straighter when he lands. This angular positioning of the legs produces a tremendous strain on the knees.
