@clucern I don’t recall the specific bacteria, other than it was considered a skin surface strain. I was fine for 7 months and had even been skiing again just before the infection developed. The six week course of massive antibiotic PIC line injections every 8 hours for six weeks was exactly the same both times. The first time all seemed fine after the antibiotics ended, but three days later I knew something wasn’t right. At that point my TKR surgeon sent me to Mayo where my original prosthetic knee was removed and a temporary plastic spacer put in before the same 6 week antibiotic injections began again. This time the antibiotics worked although I had to wait awhile to make sure the infection was gone before a new permanent prosthetic could be put in 10 months after the infection began.
