It would appear a TKR is a crap shoot when it comes to the aftermath numbness. From what I am gathering after reading comments from several places, is that if your numbness does not subside in a week or two after a TKR, you are stuck with it for life. Doctors saying it takes time i.e. a year or two etc. is just to make you feel good and to submit a bill. I have yet to see where a person's numbness has gone away in a year or two, looks like what's done is done and as you said live with it. Thing is, did any surgeon tell/warn anyone about this prior to the TKR? Mine DID NOT! even when asked what could be the down side of the TKR. Note: (surgeon said infection and clicking ONLY)
