Is it possible to jump so high

that you hurt yourself landing? Massive foot-floor coordination fuckups aside, is it possible to amass such velocity on the way back down from a vertical leap that you're sure to do yourself injury? Obviously not on Earth, but what about in lower-gravity situations?

Unless you landed differently from how you jumped. If I bend my knees while jumping, then (attempt to) keep them straight while landing, I may injure them in the landing without doing so during the jump.
