Do you have an update after having scar tissue removed? Almost 3 years since my TKR. I have pain and momentary lack of function in my quad muscle after movement. The more I move the worse it is. I can still mow the lawn and generally get around, but if I sit down and then get up later, my quad acts up. I have good motion and x-rays look good. Had a bone scan and now blood work and a CT. CR shows minor scar tissue. I’m hoping that is the problem and it can be fixed.
