Replying to How do I get back to skiing after injury?

I quit my freestyle/ bigmountain ski team because of injuries 4 years ago. I skied the next year but got injured again. I haven’t skied in 2 years and I’m wanting to get back. I’m almost 17 and I’m an advanced big mountain skier, or at least I was. I was learning to do corn 7s and I could 900 and backflip and stuff. But just asking for some help as I’m wanting to get back after my current injury (torn mcl and broken knee) heals. If anyone has any offseason ideas that would be great.
