Hi it's been a while since I've posted, but after reading your post I wonder if I am going through the same thing. I had a TKR back in January of 2019, a MUA in February, a revision in May to put a smaller cushion & in November arthroscopic surgery to remove scar tissue. I've had home & out patient therapy, nothing seems to help. I'm on a cane my knee hurts to touch. I can barely bend it & it hurts to walk. Sometimes my whole left leg hurts. I've had several xrays they always say everything is going well. I even had a second opinion to Gainesville (Shands) they too say things are going according. The doctor say my severe pain could be due to all of the surgeries I've had right behind the other. I go to pain management, but I'm tired of taking pills they only put me to sleep & when I wake up the pain is still there.
