I experienced sciatica with both knee replacements. First knee it lasted about 4 months. This knee I am still dealing with it and it has been since Dec. I have been going to PT. Got an injection which helped a little. Doing lots of exercises. I find the thing that helps the pain the most is just walking. ROM was at 119 4 weeks out and is staying at that level. I can fully extent the knee. I would be doing great except for the sciatic pain. They seem to think it is a combination of SI joint inflamation and periformis also.

I had bad sciatica after my first TKR. 1trip to my Chiropractor solved my problem. Anything is worth a try.
I am 6 months out from my 1st TKR and 3 from my second. My biggest issue is continuing stiffness and pain when standing from sitting. Hopefully all will continue to get better. ROM in both knees is great.

Hello, I am 3 weeks post sit. My surgeon said that if you get the extension to 0 first, the flexion will follow. He does not want me to sleep with my knee bent. Sit on a firm chair, put a pillow under your foot and prop it onto a coffee table. Do not support your knee . Watch a short tv program in this position. You can apply an ice pack to your knee while you are doing this. The weight of the ice will push down on your leg, and help increase the extension. When laying down, keep your leg straight and have your toes pointed upward. I put pillows on both sides of my foot to hold it in position. When elevating your leg put the pillow behind your ankle and calf. Do not put the pillow under your knee. All of these things I do and have an extension of 0 since week 1. I hope it helps you also. Best wishes!
