Ok I am looking at a few surgeon who were recommended to do Charley's knee surgery and I am in need of advice. The first one is Dr. Bradley who is located in Manassas. The second one is Dr Canapp who is located in Baltimore and the 3rd one is Dr. Pasternak who is located in Richmond. Has anyone had this procedure done in this area and have any recommendations? I need to get it done soon his knee is popping out quite frequently now.
