Comments: Dr. Perricelli is an outstanding orthopedic surgeon. He replaced both of my knees in 2 different operations and continued a very informative follow up after surgery. He is always upbeat and completely answers all of my questions. His knowledge and positive approach make you feel very good about your recovery. He leads the orthopedic department at St Clair Hospital, rated one of the best hospital in Pittsburgh. If you need hip or knee surgery, Dr. Brett Perricelli is your very best option.
