Sorry I did not see this …. I got my knee replacement one year ago was never able to gain flexion …. Always had residual pain ….. my original Dr would not do anything I sought a second opinion …. Which first appointment Dr told from original Dr X-rays that the replacement was slightly to big and may be causing my problems…. Within a month I was in got the knee replacement ……my new knee is two sizes smaller and recovery has been amazing…. I hope this helps you
