I had my left total knee replacement, July 19, 2018 and it went really well. Therapy was really effective. I had my right total knee replacement on October 18, 2018 and it went really well too. Therapy was good too. Dr. Owen O’Neill and assistant Jessie are super helpful. I am now ready to have surgery on my spine, since my knees are doing so well. April 2019. I AM VERY PLEASED WITH TCO.
