About 6 years ago I had a RTKR. I had continuous trouble with it, trying all sorts of things. Finally after a year, my surgeon said the only thing to do was a revision ….. doing it all over again completely. So, a year later he totally redid it. It has been great ever since. Now my left knee is acting up …. not living where I was when I had the first one done, I think I'm going to go up to MD, to the same surgeon I had before, and have it done there. He's the best one up there. After a few days in the hospital, then I'll go to rehab. for a week, and then one of my kids, or a friend from MD can bring me home. I would think one of the Orthopedic Surgeons down here could do rechecks and send me to the hospital rehab. When the weather is nasty – rain, snow, etc., wow does that knee hurt. The right one does too, but not nearly as much as the left one. So, I have a feeling there may be another TKR in my future. I'm not concerned at all this time ….. I don't mean to sound cavalier about it, and I know all surgery is serious, but my doctor in MD really did a fabulous job.
