Differences in knee ligament moment arms might contribute to the higher rate of ligament injuries in women compared to men

Differences in knee ligament moment arms might contribute to the sex-disparity in knee ligament injuries. We used a population model of the knee to create finite element simulations of varus-valgus rotations and found that the moment arms of the medial and lateral collateral ligaments were smaller in women compared to men. This might potentially contribute to the higher rate of ligament injuries in women.
