I had knee revision surgery from Dr. Johnson. He did a fantastic job. I was so pleased with my recovery and how much better I felt compared to the first time around. My care was excellent. He explained everything about the knee surgery, meds to take, PT and what to expect. I would give him a 10 star rating plus he actually comes in your room to sit down and talk to you before and after the surgery. Dr. Johnson and his assistant Karen are the best. Thank you so much!!!
