I am 6 months out. Still have stiffness & pain. I also have had sciatica pain. I had manipulation done also. Actually this is my 2nd TKR - 1st one i had sciatica issues too. This time I went to chiropractor and got relief immediately but if you are still limping some it will bring it back & may require you to go back for an adjustment from time to time. Night pain is the worst for me. I have to get up & walk it off. Then ice pack & try to go back to sleep. I didn’t have night pain with first TKR. I feel my pt first time was so much better than last. (Moved to another state so I couldn’t go back to first pt). Your pt is most important. My ROM is bad. Pushing myself to go up & down staircase. TKR is not easy for many. Age I believe makes a difference or perhaps I choose to blame it on that. 80 yrs old.
