Outriggers are meant to support people that can't ski without them due to some disability, whether it is cerebral palsy or the fact that they are missing a leg. Keep in mind that if they fall, they fall just as hard as everyone else, and that they don't ski with outriggers because they have an injury that they need to worry about. However, outriggers would probably work, but you would need to find a pair first. Perhaps google for disabled ski teams in your area.
Keep in mind though, if you take one hard fall you will be FUCKED. Possibly for the rest of your forseeable life, at least for skiing. ACLs are something that heal slowly and are very important. If you mess it up even more you could seriously never ski again. I would honestly take the necessary time off, because you could get seriously fucked up if you fall and hurt your ACL again.
