ACL Tears

So, i was talking with some friends tonight about past injuries and acls were brought up often. Surprisingly enough, i was one of 12 people in the room who did not tear their acl. So that got me thinking. How many people actually tear their acl and possibly lose their future sports. I wrote that paper about my sister thinking that she was possibly a unique case, but its more common than i thought. 1 in 3500 people tear their acl each year. If you realize how many people in this world, let alone nation, there are thousands and thousands of acl tears each year.
