"The details: The injury happened Feb 22 in the mid sized terrain park at Alpine Meadows. I was feeling very fine on my new Black Pearl birthday skis. Although I prefer to ski off the groomers, my daughter wanted to ski the new mid size terrain park so we had been playing around there hopping off the smaller jumps. One of the jumps dropped off more quickly than I had realized, and I caught some air and landed in a flexed position overweighted on my left leg. I don't know if the injury occurred on impact or as I twisted, and I'm not sure if I fell rearward or forward as I rotated over my left side."
Just to clarify the facts. I will say it's difficult to go over the handlebars landing flexed off a jump without first slapping back. But whatever.
Look, even if this incident doesn't qualify on a post incident examination technicality, the Ski magazine blurb is disingenuous because it gives the implication that no one has ever torn their ACL on one of their bindings. That's all I'm saying and I'm pretty sure that was the OP's point when starting this thread.
