Had TNR 7 months ago, toes tingled after wakening for hours, hours later bottom of the foot went numb (heel area mostly), Tried everything to stop the numbness for 7 months now, nothing worked. Knee is doing fine after much pain for a month +, but the heel of foot stays numb. Numbness is not getting worse, If anything the numbness has improved .000001%, and in about 400 years I should feel my heel again with that rate of improvement. People say it's not typical to get this, but it does scare me about getting the other knee replaced.

ask for and ABI test. it is like a blood pressure test for the legs. that is how they figured out that my popliteal artery was pinched behind my knee and I need yet another surgery to fix the artery. My foot is still numbish feeling but at least my toes are no longer purple. my TKR surgeon ask me why I waited 60 days to get it fixed...you could of lost your leg. HE DID NOT LISTEN TO ME! I told him right after surgery and the next 3 following days and at my 2 week check up. my primary was the one who ordered the ABI test. I told several ortho drs. that it was not normal my other knee wasn't like that. Good Luck!
