Comments: Dr Perricelli replaced my right knee. I had a very difficult knee condition where I had a 20 degree extension contracture combined with a 15 degree valgus position. His experience in revision surgery and technique of pain control gave me confidence with him. He cares for all of his patients and shows it through his pre and post surgical behaviors. I had very little pain through the whole process, amazing. All of the physical therapy and hospital nurses rave about how well his patients do.
