My advice, take a couple of days off after surgery and then get back out there and do whatever you feel comfortable doing.
btw - my repaired knee is like greased lightning now. It felt better immediately after surgery but it took several months to get to where I could take it for granted, now feels better and has better range of motion than I ever remember. Unfortunately it feels so good that my other knee bothers me by contrast.
