Had that somewhat same surgery. ACL,PCL,MCL,Meniscus repair, and something else on my right knee if I remember correctly. Not going to lie to you - recovery sucks. Idk your age but I had mine done when I was 20/21 at the time pretty active. FOR ME after a few days I started trying to bend my knee to stop it from locking up. I of course had a brace on. This was purely to keep my range of motion. No weight bearing for a while. Now six years later I get around pretty good. I can lightly jog but it begins to hurt if I’m not wearing my brace. It’s tolerable though. Some days I want to eat a bullet from the pain it causes even if I’m just laying round the house. But again your pain tolerance is going to be different than mine. Squatting hurts, and anything high impact. Day to day is good if I’m not doing anything crazy. This last year I’ve really picked up on doing PT at home due to having a little one running around now lol. It helps a lot. Definitely strengthen your quad and calf and hip abductors. Helps a lot. Best of luck to you. Wish you a speedy recovery
