Q: I am a 35-year-old woman who recently had surgery to repair a torn ACL in my left knee. In doing research on the Internet, I noticed that females seem to be more at-risk for this injury than males competing in the same type of activity. Why is this?

A: This question has an answer with many theories and ideas, some farfetched, others physiologically proven. What does seem to be true is that females are indeed more prone to ACL injury during similar activity.
There are two things that are main contributors to this: muscle imbalances and a greater Q-angle.
