I will try to keep this simple I saw 3 surgeons 2 at HSS and 1 at Mt. Siani. They were all very nice people, but I knew the moment I met Dr. Demetracopoulos he was the man to replace both of my ankles. He LISTENED to what I had to say, and by looking at my x-rays he knew what needed to be done. He explained everything to me and answered all my questions. He made me feel he really knew what he was doing, and that gave me the ability to relax. If you look at his education it's at the top of anyone's game. I can assure you I would have never left him do my second replacement if my first one wasn't GREAT. They were 7 months apart and my new ankle carried my whole body for the second replacement with no issues or swelling. Now I have 2 new ankles both done by SUPERMAN Dr. Demetracopoulos. By the way his staff is the BEST - Megan (his right hand), David (the gentle giant; make sure he removes your stitches - he doesn't hurt at all), and the 3 girls in the office will solve any problems you may have. They are great!
