Seven years ago Dr. Duffy did a total knee replacement on my left knee. I return to Dr. Duffy's office with concerns and issues about my right knee. He explained to me that I did have reason to be concerned but that we were going to watch it and replace only when necessary. He is an excellent surgeon and has perfect bedside manner. He's the only orthopedic surgeon I would allow to operate on me.
