I had a completely torn ACL with 2 small tears on my meniscus along with slight MCL damage. This will be my second year back and I really only notice knee pain when landing jumps poorly, such as when back seat or if my leg is close to locked. That said, I don't ski as hard as I used to before my surgery. Since the end of my rehab I have been going to the gym very often as well as biking during the summers.
If I were you OP, I would start getting your stuff together on the therapy and rehab. Get your knee strong and your flexibility back in your leg. Your muscles provide loads of support to your knee.
Stronger muscles = less chance of injury = better skiing
