Over three years ago, Dr. Chambers removed a metal on metal hip that I had replaced by another medical group. He gave me a Smith and Nephew, ceramic hip to replace the recalled metal hip. I work out with a personal trainer 3 times a week. There is nothing I cannot do; you would not know I have a hip replacement unless I told you. It is amazing, I have not had any problems The hip works just like a hip should work. I highly recommend Dr. Chambers, he is a highly skilled surgeon. I am now in the process of possibly having a right knee replacement. I put my confidence and trust in his hands.
