Hi @mhort1213 - It was a total knee replacement. I started to mention that on my last post but my typing fingers had gotten tired. LOL. What I meant to say was that the video is my surgeon talking about partial knee replacement. He is an orthopedic surgeon at Mayo Jacksonville. He started using the robotic arm assist for partials about 2010 but in May 2017 he started using it for total knee replacements. He says it takes a little bit longer and its a little bit more expensive since they have to do a CT Scan of the knee, but he says the increased accuracy is worth it. Don't know where you are located but Dr. Cedric Ortiguera is terrific if you are anywhere near Jacksonville - or inclined to travel here. Best of luck!
