Comments: Dr. Luu rocks! He’s done partial replacement on both knees the last one less than two mos ago and they both feel like new. PIH was blessed to have a surgeon who does partial knee surgery, I’m very active walking on avg 20,000 steps a day I’d be on a couch feeling sorry for myself without Dr. Luu. He is not only a Great physician but a down to earth human who takes the time to listen. I can’t say anything negative about him.
