I had meniscuous repair in my left knee last Sept and did just fine. As all the others have said "follow doctors instructions" and you will be fine. Icing and elevating my knee above my heart for 20 minutes every hour the first day was very helpful. I started therapy about 4 days after surgery and I truly believe in P.T. Played golf two months later and had no problem. I am using a stationary bike 3 or 4 times a week and I believe that helps tremendously also. I for one did not have tremendous pain. Good luck to you, you will be in my prayers.
