From what I understand, it had nothing to do with how good (or bad) she was doing in practice. The way she described it, it seemed more like a fluke accident than anything. Someone got in the way and she had to bail out of the jump to avert a spectacular collision.
I assume her competitive mentality would not let that scoring mishap bring her down. In fact if it did, I'd argue that her will is not strong enough for a skater. Did Rachel Flatt give up after being hosed at the Olympics? Or Nagasu after losing a National title that several argue should have been rightly hers? I'm willing to give these skaters more credit than that. It's the nature of a judged sport- sometimes you get the calls, or the benefit of the doubt, other times you don't.
If there was one thing I would attribute to Meissner's demise, it's that she filled out after 2006 and she never adjusted her technique to match her new body. SO the jumps went bye-bye. And, like most other jumping beans out there that have nothing else to offer, as soon as that happened, she was toast. The injury was just an exclamation point on the message being given to her to move on.
