Here is how I made out with the Mackie Hinge Knee brace. After 2 months of using it 3 times a day for 30 minutes each, my Flex is finally at 115 degrees. It did work, but if you can't take the pain, I don't recommend using one of these. I am walking great and my knee feels like my own. I don't even think about it any more unless I am doing exercises or going to Physio. I was going to shoot for 120 degrees, but I can live with where it is at right now. Thanks to everyone that helped me through this, I am coming up on 6 months since my TKR and I am totally atisfied with the results.
