Thank you. Never heard of a TKR. Acronyms throw me every time and I have trouble remembering them even after being told. We don't have internal medicine doctors in Australia, but we do have GPs, general practitioners, which I take it is your PCP - which I had to google through pages of links to the drug Angel Dust (PCP/phencyclidine) to find. IM MD google search took me to Ironman Maryland and your immigration department. I do try to find these things but sometimes, no luck.
