@janicemmccarthy : had some different issues several months after TKR, and it turned out that one of my legs was slightly (really, very slightly) longer than the other one. Whether a result of the TKR, or if it was always that way, I don’t know. But it caused problems with walking, and custom orthotics helped fix that. I may be way off base, but I could not hurt to have your leg length checked by your PT professional. May contribute to your pain by throwing your weight load on the ankle/heel out of whack.
