PT is the key to a successful outcome, do exactly as instructed no more no less. I had both hips replaced the same day, the wife has had one hip and one knee. She has the second knee scheduled for a week from now, only had a day or two post surgery where the pain was bad. In addition to doing PT she goes to the gym 3-4 times a week and rides the recumbent bike to help with flexibility and range of motion.
