I had a TKR of the left knee in August 2019 and a TKR of my right knee in July 2020. When I finished PT on my left knee in December 2019 my ROM was 130-0. I noticed in May that my toe was dragging while going down stairs and it was harder getting into my car so I went back to PT. My ROM measured 102. By the time I finished with PT in June it was back to 124. When I was in pre-op before my right knee replacement I mentioned this to my surgeon. He decided to manipulate my left knee while I was under. He reported to my husband that there was significant scar tissue. It felt great after surgery; no more tightness or feeling like I had a 3 lbs weight attached to my knee. At this point, I was in PT for my right knee replacement. I started suffering horrible sciatic pain and the focus of my PT transitioned from knee to sciatic. At the end of PT, my right knee measured 124-0. My surgeon sent me to a pain management dr who did an injection for my sciatic pain (which helped right away). In the midst of all this, I didn't notice the change in my left knee. To shorten the story... I'm 6-months post op from my Right TKR and both of my knees have tightness and heaviness and feel like I'm dragging around 3 lbs weights on both of them. I'm still experiencing some pain in my right knee (feels like bone pain) but that's probably to be expected. My surgeon sent me for an MRI of my left hip to make sure it wasn't causing problems with my left knee. I saw a colleague of his (does both knees and hips) who thinks I need to have the scar tissue removed from both of my knees...He estimated my ROM on both knees to now be 105 cold. I'm scheduled to see my surgeon next Monday to discuss. After reading some of your posts, I'm not sure whether I should pursue arthroscopic removal of the scar tissue or not. Thoughts?
