Comments: I cannot say enough good about Dr. Nayfeh, his staff and the entire knee replacement process. I had a "traditional" knee replacement in 2020 and the "jiffy knee" was such a better experience. Pain has been less, rehab was much better. Dr. Nayfeh lays out a program for you and I feel that if you do what he says and follow it you will have as smooth of an experience as a joint replacement can be. I was scheduled with another surgeon and as soon as I met Dr. Nayfeh I canceled and switched. A great decision!!!
