The fact that she had a major knee injury a month or so before Alex's rant makes his behavior even worse. Maia is barely back on the ice and he's cursing her out for 40 minutes over a rocker turn?
I suspect the fracture was probably a hairline fracture or severe bone bruise (or both). I've heard (non-elite) skaters in my area talk about "breaking" a bone when it's actually a bone bruise (not quite a break but still painful and debilitating).
IIRC, Penny Coomes had a fracture of her kneecap (i think she said it shattered in several places

) and she had surgery and was off the ice for almost a year.
