I'm happy to hear good results! I had a horrible experience with back surgery (double fusion) at a time when they did not give a nerve block. So a bit of 'post traumatic' going on, too..I am now looking to do robotic along with the Iovera. I love my surgeon, but he doesn't do robotic, and I like the idea of having the hardware made to my knee specifications..again, so happy you've had a great outcome!
