Y'all got nothing on my friend's knee. He's pulled his ACL, torn it, torn the MCL, shattered the kneecap, has Osgood Slaughter (sp?), and tendinitis. The worst was the shattered kneecap playing lacrosse... He was playing D and the goalie went to score, lost it, and the kid from the other team drilled the ball at him.. Down he went.
