a bit tangential probably, but girls are also much more likely to tear their ACL than boys. i know this because an ex tore her ACL and MCL as a cheerleader in high school and looked into some of the stats. I don't feel like looking it up but I want to say that girls cheerleaders are actually a really, really high injury risk in general? This article delves into the ACL stuff and while I know nothing of the source, it seems to be well cited
