@saeternes I live in southern NH so Boston is only about 55 miles away and I go there for most of my medical care. The surgeon who was the developer of the Conformis knee is in Boston (Brigham and Women's Hospital) so I went to him because I knew I wanted the Conformis knee. I had heard that recovery and results are generally better.
Initially I had a lot of pain, which really puzzled the doctor. He was seeing me frequently to check up on it. Then, almost overnight, the pain went away! It lasted about six weeks, maybe a bit less. I had the surgery in mid-October (2017) and on the first weekend of December I was in NYC for the celebration of my daughter's marriage and I walked all over the place, pain-free. Two weeks prior to that I was worried I wouldn't be able to get around in the city, but then the pain vanished so I have no idea why that happened, nor did the doctor.
My ROM is about 0 - 120. The flex part of that varies a bit depending on who measures it and the day. It has been up to 123 and down to about 117. Based on my results I would recommend the Conformis knee. I love walking and never feel knee pain when I walk. I particularly love walking in cities. We were on vacation last October and I was walking many miles each day. My husband had to go back to our hotel room because he couldn't walk any more. I felt like the Energizer bunny!
If you go to the Conformis site you can find what doctors in your area do that knee.
