Replying to Skiing with torn ACL?

I recently had a pretty painful accident on a trampoline and thought I'd done serious damage to my knee but A and E said nothing was wrong. So I got back on skis a week later for a very mellow session without any jumps and managed to avoid any pain. My knee seemed to be making progress every day, but I still lacked some flexibility to decided to go to a physio to make sure I recovered properly.

He then informed me that I'd torn my ACL, but this was only 3 weeks later and I was managing almost every movement pain free which is very unusual. He asked if I'd injured it before, which I had about 4 years ago when I massively over extended it trying to land switch in pow but catching my tails, so its entirely possible that I actually tore it then and never realised. Also, the recent accident is not typically the kind to cause ACL damage whereas the one from 4 years ago is, but I honestly have no idea when I tore it.

The physio said I'm absolutely fine to continue any exercise (including park skiing and trampoline) as long as there's no pain, and thinks I'll be fully functional in just a few more weeks. Its been 1 month now and I went back to the snow dome park (I'm from the UK) and managed to do basic rail tricks without any pain, so I know I'll have no trouble with casual skiing around a mountain or anything like that, but I'm yet to properly send it or take any big impacts. I know that some people never bother with reconstructive surgery and have a full recovery without it. However, I'm supposed to be going to Japan for the season in a couple of weeks, and was really hoping to see a lot of progress on jumps this season but I don't know if I should seriously lower my expectations now?

Was just wondering if anyone has had any experience skiing around with a torn ACL without reconstructive surgery and if they managed everything as normal or if it seriously impacted their performance?
