neuropathy, after tkr, is ( unfortunately) normal albeit surgeons, in general, won't share that. i'm two weeks into my second tkr but my surgeon was very clear that neuropathy is definitely possible after tkr. for me, taking a gabapentin at night to sleep isn't a bad trade-off for the ability to be mobile again without pain. a lot of this can be mental if you allow it to go down that path. i learned to accept and move on.
good luck.
