olicAfter both my ACL surgeries I left it a minimum of 9-12 months before skiing again, trust me it's not worth messing it up, the 2nd ACL repair surgery really sucks (sometimes needs two operations). Do what the physio and your surgeon tells you, build the strength back gradually. You can do some prehab before the surgery to help the recovery after.
Most of all though sending you good vibes and I hope you heal up fast!
All of this.
After my surgery I was in my first year of grad school. I was in socal and did not have a Mammoth ski lease yet, and school was taking up lots of time, so there was not a whole lot of pressure to ski. I skied maybe once in January and took it easy, then again in late March when it had been about a year since surgery. Looking back I was lucky, my situation made it easy to focus on school and rehab and wait until I was fully recovered. The next year I got in around 30 days and I was fine.
If you are going to live in the mountains next year I would suggest doing the surgery as soon as possible, so that you will have time to rehab. If you are willing to not have a big year next year you can wait. It really depends on your situation.
