First of all, I apologize if I am reinventing the wheel by bringing these issues up. I did search on IT Band and back pain. I am 7 weeks out of double knee replacement. Horrible first 2 weeks which I expected. 4 days after surgery my low back pain started, 10 days after surgery something popped in my right knee when I came down a few steps. Since then I have pain on the outside of my right knee when ever I lift my leg when trying to walk. No pain when siting and doing leg extensions. I can bend both knees to 130 deg and straighten to 1-2 degrees. I have what I imagine to be the common problems after TKR (tightness...) I don't need a cane unless walking on rough ground, up steps, or very far. I have been doing outpatient PT twice a weeks, 7 different stretching exercises 3 times a day, seeing a Chiropractor once a week for back pain, and therapeutic massage on my IB band once a week. I am also walking a 1 mile a day. Nothing is helping the pain on the outside of my knee (or back) which can cause me to walk with somewhat of a stiff leg. I'm suspect the bed rest after surgery and change in my gait is causing my low back pain. Back hurts worse when sitting down, but also hurts when standing, or laying down. Ice does help . I know I am still in the early stages of recovery, but am having a hard time seeing any light at the end of tunnel. Not sure how to proceed. Patience with pain is not exactly one of my virtues. Any thoughts, ideas, or guidance would be greatly appreciated. Thank you all.
