I don't think that hitting jumps falls into the category of "normal activity" as described. From the double tear you have to worry about hyper-extenting your knee, heavy impacts as well as over twisting all of which could cause reinjury. At the very least I would back down the din setting on your injured leg and give it time to fully reattach as stated above. A few extra months isn't much compared to a life time of problems.
I blew my ACL during my last Tahoe season. I got my surgery in late March. My first year outside of Tahoe was also my first year in grad school, and I was getting used to living out of the mountains. I only skied about 10 days that year, and I was pretty cautious. I could have skied more, but I would definitely go slow in the early part of the year.
Now I ski on weekends, and get about 40 days a year. My second year after surgery I was fine, it just takes a bit mentally to get over the fear. By my third year I was fine, both physically and mentally.
I still wear a brace, but I don't need it. I figure I might as well wear one, as it could prevent a hyperextension.
I was lucky, in a sense, in that my first year out I was in a different place in life, and able to give my knee the time off it deserved. If I had been going back to Tahoe for another year, it would have been difficult. As I said before, I would take things VERY slowly. You don't want to get hurt again, or retard the healing process. I would scale back on big cliffs or big park jumps. Give yourself a couple of months of skiing before you get serious.
The stronger your leg is going into surgery, the more muscle you will have after it has atrophied. If your muscles are weak before surgery it will really hurt your progress.
The part about continuing rehab is absolutely crucial. My insurance paid for about 12 weeks, as I recall, and by that time I was jogging lightly. Ask your physical therapist for a program you can do in the gym once you stop going to rehab. It is critical to keep training hard on your own, as that is what will get you strong for the season. You need to get those leg muscles as strong as possible, that will give you the stability for skiing. If you stop training when you are done with the PT you are risking another injury.
