Nomilynn, I'm currently recovering from knee replacement surgery. I'm SO glad that I had it done. Right now is the first time in a year that I haven't limped!!My left knee had a lot of arthritis in it and hardly no cartilage left. I'm still healing inside my knee, but now I can walk almost normally. Nomilynn, tell yor father that most of pain that he will feel will be right after the surgery. afterwards the pain becomes less and less. How old is your father? I had it done at 55 and I was the younger side to have it done. Nmilynn, would you PM me on the outcome of your father's surgery? I would like to give you and your father any encouragement that I can! I wish your father good luck, and my prayers are with the both of you.
