Comments: I spent many years as a professional ballet dancer. After that, I was still very active in athletic endeavors such as tennis and skiing. As a result, my knees were bone on bone and very painful. I consulted with Dr. Greenhow after his being recommended by another client. I have had both knees replaced and I have had no regrets. It was really rather unbelievable how fast I recovered and that I never had any pain from the first time I stood up after surgery. I think this new method surgically is truly amazing.
