Hi I am in same place …. I am year out august 12 six weeks after tkr had manipulation…..had pain this whole year constant therapy but not getting anywhere …. I sought second opinion after my original dr would not do anything …,i found from new dr with my original dr X-rays that my new knee is slightly to big…..I know how you feel I was angry and frustrated how dr could see me in pain and not able to retain any progress …. In retrospect he knows exactly why I could not get anywhere…. But I know you can’t have revision for 1 year that’s why I had to wait…. I am scheduled for revision July 28 I am so anxious more so than first surgery…..new dr is very confident he can help me but did say revision are more difficult…..but if I can get like 90-95 flexion than I will happy …. So good luck keep me posted how you are doing …..
