This was explained to me by a women's soccer coach as she and two of her students had suffered ACL injuries from the sport.
ACL injuries are epidemic among girls in high school and college, particularly among those playing soccer and basketball. Their bodies are just not made for those explosive cuts and moves. Go to any school and you will see several girls hobbling around on crutches.
That holds true for basketball as well. Something about the knee/leg structure of females that causes them to have more acl injuries per capita than males.
