I don't remember if it was the ACL thread or another that had a bunch of research based info. However, I don't think you're going to find what you're looking for.... at least not specific to soccer. They are more reports that focus on "sports related" along with common age ranges. You'll have to do some searching.I am interested. The ACL thread seemed to be mostly about those who already had a diagnosis. "How do you get back to soccer?" seemed the main question.
I am more focused on prevention. Is there a thread with good info on that?
