Your timing is impecable. I had knee surgery 10 days ago for a torn meniscus as well as a repair to the cartilage in my femur.

6 years ago I had surgery for my meniscus (same knee....yes, I'm consistent) and after that surgery, I was back on my road bike in 10 days doing a metric century. Not at hammerhead pace, but a comfortable pace, no major hills but still a good ride. I did physio & my exercises religiously and experience absolutely NO pain post-operatively once I was given the go-ahead to get back on the bike. (the PT had me on the stationary bike less than 24 hours after my surgery).

This time around, however, I'm experiencing some issues. It could be because of them drilling into my femur (which they didn't do first surgery 6 years ago). I have been on my road bike (not my mountain bike yet) but a flat, flat ride. (which is tough to find based on living in the mountains).

I'm rambling here. What I'm getting at it, listen to your knees and your PT. Absolutely, you will be back to being able to ride up 26% hills. Not tomorrow, but in time. And rehab is quick if it's just a torn meniscus. ACL is longer but again, you should be able to get back to what you were doing previously.

Good luck!
