I have had two complete knee replacements the left was done by one doctor and the right by another. The left leg was operated on by Dr. John Mann. His operation was perfect. The leg healed up, the pain was gone, and the leg functioned normally. I couldn't ask for a better outcome. The right leg gave me a great deal of trouble after the operation, as I've said this leg was done by another physician. I went back to Dr. Mann and he examined my right leg briefly and within a couple of minutes told me exactly what was wrong with it, stated that he could repair the leg with arthroscopic surgery. That I would be in and out of the operating room in under an hour. He stated that the problem was scar tissue had built up under the knee cap causing my leg to be unstable and causing it to make sounds one could hear from 10 feet away when I bent the leg. I had surgery on the leg 4/7/14 by Dr. Mann. He was absolutely dead on right as the leg now functions normally, healed right up, on a pain level of 1 to 10 I never reached 1. The only thing was a little soreness. I'm already out working on my yard something I haven't been able to do in 15 years and losing wait for the first time since I can now exercise. If you want the best and you won't settle for less then go to Dr. Mann. You simply cannot do any better.
