Tore my ACL in volleyball. Was chasing the ball out of bounds on wet grass. But that was only my second worst injury of the day. As I went down I landed on my right shoulder, HARD. Busted it up, and that was even more painful then my ACL. Have not played any sports involving twisting action.
I also suffered a pulled groin last summer while running, and aggravated it stepping out of a kayak later (the kayak moved away with one foot still inside).
Fractured a rib about 10 years ago, and no idea how it happened, but very painful.
