Crazy story, acs.
The closest I can come to that is when I was playing tennis and was certain that I'd tore my ACL or something. I had just run to my left to hit a backhand, and I was mostly off the court. I was doing the traditional sideways hop back to the middle of the court when my opponent laid out a beauty of a drop shot. It was straight in front of me, so I stopped, planted my left foot, and pushed off. Apparently, it didn't like that.
My knee made a popping noise, and I felt a stab like a needle right through the outside of it. I immediately dropped to the ground. It was weak for a second, and I was up walking around in minutes. My opponent said he heard the pop all of the way on the other side of the court. Never had a problem since then.
I still won the match, too.
Anyway, watch out for trees from now on, ok?
