Hi @cobweb - I'm sorry I'm just now getting back to you. I had a little bug and was under the weather this week. Wow! I know your situation must be scary. I would NOT want to hear that there was a possible fracture. Also, I have never heard the thing about only 2 replacements - then amputation. And I can't find that in any research I've done. We have a fair number of people here who have had TKRs and even revisions. I'm going to ask these folks if they have heard that amputation was the only option after a 2nd TKR: @contentandwell, @JustinMcClanahan, @lynnwade54, @doodles418
