i had my knee scoped about 10 years ago now. they cleaned up the meniscus, repaired the PCL and MCL, and also had to loosen up the ligaments on the outside of my knee to stop my kneecap from dislocating any more. (damn high school soccer) i was in rehab/physical therapy for ~6 mos trying to get back into playing shape.
best advice i have for you is to constantly fight the soreness by never stop exercising it. and do the exercises on your own. i didnt do any outside training for the first couple months, and i was dying in my therapy sessions. and after about a month of therapy you’re gonna realize how much you can still do and then i would set goals on recovery. i told myself i was going to be playing sports 6mos after my surgery and i was running track and throwing shotput after 5mos.
after about 2.5 years my knee, and i dont need to wear a brace or anything for sports/working out.
hang in there, the hard part is over. youll be running around in no time.
