Sorry to hear you are having so many issues following TKR. Unfortunately, people don't understand what it's like to walk with one leg shorter than the other - it's like stepping in a hole with one leg and it throws the hips out of alignment when then pushes the back out of alignment. Everything is connected. A prosthetic shoe maker "may" be able to fit you with the proper shoe to help the shortened leg. I say "may" because the ones I have seen usually just asked what I wanted and said OK. They're supposed to provide their professional opinion, not the other way around. Anyway, I will pray for you.
