How I injured my knee.
 

I had a chance to jump out of a perfectly good airplane and I injured it sky diving. It was a tandem jump. We landed a little bit short, my heel hit the ground hard and I heard my knee pop.

I received my first knee injury playing basketball. It was in the first half of the game and I came down for a rebound. I went to turn and make a pass and a girl hit the outside of my knee. There were two pops and I had a torn ACL.

When I injured my knee on the second vault I heard a loud snap and I immediately went to the ground. I knew I was hurt.
