Tore ACL February 2020, surgery March 2020, was skiing again December 2020 after a shit ton of PT. Wasn't confident on skis again until March 2021. Spent another summer/fall in the gym, came into this season feeling fairly confident but I'm still scared on jumps (that's where I tore mine). The knee feels relatively normal but still not like it used to. Some days are better than others and it gets sore after a long day on the hill.
Just did 4 outta 5 days on hill last week for about 6 hours a day (by far the most I've skied in a short amount of time since injury) and felt surprisingly good after the week was over. Still a lot of work to be done getting stronger/more flexible going forward. If anything getting hurt has made me focus a lot more on my body which has been great.
Good luck! You'll be back before ya know it as long as you put the effort in!
