I’m no doctor, but if it’s true that you could be at risk for tearing your meniscus without corrective surgery on the ACL, I would have the surgery and possibly miss a season. I torn my meniscus about 12 years ago and had to have quite a bit of it removed. Since the surgery, I can no longer do any activity that involves impact to the knee. Well I can, but not without several days of pain following the activity. I can ski, barefoot, and wakeboard, but I no longer land in the flats. I can ride a bicycle or use an elliptical but running is not an option. I did a few light squats at the gym last night, stood on concrete for 10 hours today and my knee is killing me. Once cartilage is removed, it doesn’t grow back.
Bottom line: Follow the doctor's advice. And good luck.
