I had mine done the end of September and with united health care and medicare I got away for $250. Anterior install and I was on home therapy for 2 weeks and then off the walker and back bowling in a total of 6 weeks. That 90* thing is a pain to not do. I kept exceeding it a little. They had me up and walking with a walker the same day as the surgery and out of the hospital the second day. I'm back to doing everything pain free and I love it. They are doing fantastic things in the operating room now.
