Hi Spex 10, I had my right knee TKR on Oct 11, 2016 and I'm also experiencing issues with my ROM. I understand what your experiencing it's very frustrating and a real bummer. My extension is 10 and my flexion 90 (assisted). My knee is so tight my poor PT physically can't get it straight no matter what method he uses, and it doesn't hurt me when he does it's just that my knee is so tight it's not straightening, but the bend is slowly getting better. I elevate and ice daily, I barely do any home excercises other than daily life and some flat ground small walks. When you mentioned arthrofibrosis I looked it up, interesting reads. It's something I will ask my Dr. about at my next appt - 12 week check up. I hope your ROM works out for you either with a MUA or with out because that's the goal, right?
