I had my surgery booked with another surgeon in Madison. I decided to get a second opinion as I heard really good things about Dr. Niesen. Boy, am I glad I did that! After spending nearly 40 minutes (wow!!) with him I felt that he was the right man for the job. I made the change to have him do my knee replacement when I saw how complete and meticulous he was in clinic! I knew I was not going to get that type of attention and care anywhere else.
