Welcome to the club.
Had a surgery 2 and a half years ago,
now i don't remember the exact names of things they did to me in rehab center but it was something like this:
- i got special light shit on my leg
- they put some shit to contract muscles in my leg
- they used really cold air to get rid of the swelling
Then after i could walk pretty well i immediately started exercising and stretching the leg. You have to make sure you are able to sit on the floor without bending your knee.
I had my exercises i got from physio therapist somewhere maybe i can find them if you want to see them.
As for how I'm doing currently i didn't get back to all the sports i have been doing but if you ask me i can still do a backflip and do weight lifting so it's not too bad.
