from my physio wife - note this is data on males under 18... - don't push it, strengthen the crap out of it. the data shows there is an 80% chance of re doing the injury for (males under 18).... so strength, strength, strength and maybe some "social" skis to build confidence until her performance gets better. she used a whole lot of other big words that I cant spell. But hey you've seen the specialists - do what they say (if they understand what skiing involves)
