I am now at the 7 month point since total right knee replacement. My ortho surgeon is very pleased with my recovery to date (too slow for me). I have zero pain when standing, sitting, or lying down. But whenever I get up from sitting in a chair for ore than a few minutes, my right knee is very stiff with a lot of soreness/discomfort on the right side of my knee. Walking, doing PT exercises, pedaling on recumbent bike, heating pad, Aleve, whatever ... nothing seems to help with that right side soreness! However, every month I do notice some improvement ... but very slowly.
