I just had my revision last Friday, and know well what you're going through. I kept myself as busy as I possibly could in the days and weeks leading up to the surgery date, but still had times when I needed to get off my knee and would then think too much. That's when the kangaroos would be jumping the most and I hated that feeling. But, I had a really easy time of it in surgery this time. I let them do a spinal for the surgery, whereas I have always had a general in the past. I woke up with no pain at all and no nausea, and a very clear head, and best of all they were able to use a deep sedation of some type so I wouldn't wake during it. I was awake and talking; whereas in the past I was in the PACU for hours and hours, this time I was barely there at all before going to my room. My pain has been handled totally, except for a short time between when a nerve block wore off and they put in my ON-Q pump. While the total fear I had before the revision was a result of all the problems I have always had, it has turned out to be a great recovery so far. I know I may have some rough roads ahead, but so far it has turned out to be a stress free recovery and I panicked for nothing.
