Hi, I had my left knee tear fixed 2 summers ago. I didn't have much pain at all but was diligent on going to physical therapy. That helped so much!
The surgery was out-patient and I remember just taking Ibuprofen for a few days and iced it a lot, keeping it elevated as much as possible.
I have cartilage loss in that knee but it's really fine now.
I'm doing Pilates and it doesn't bother it at all.
I realized that the reason that knee wore out faster than the other one is b/c I always bend on my left knee first. Until the tear I never realized it. My other knee is fine.
Good luck!! You'll be fine :)
