I realize this is an old post but I am posting on it to help others if they find this listing. I had bi lateral knee replacement 4 weeks ago. DO THE PHYSICAL THERAPY! I can walk on my own, I can go up and down the stairs, I can get out of a chair, and I am on NO pain pills. Yes, PT can make you sore. But if you refuse it you are going to have a LOT MORE soreness.View Thread
