That would of been me! I had the popliteal artery surgery on April 11, 2019. The artery had been pinched off during my TKR surgery which my surgeon refused to admit. The artery surgeon took out a dead dried blood clot that was in the artery. Thank goodness it was an artery that flowed from my knee down otherwise it would have flowed right to my heart. When I awoke from surgery my foot was warm and pink, not cold and purple. the only problem was that it was almost 2 months that I had not blood flow to my foot. I ended up with permanent cell and tissue damage and have some numbness on the bottom of my foot and a few of my toes, but as my TKR surgeon so graciously put it when I told him what he did..."Why did you wait so long to get it fixed, you could have lost your leg" and still have my leg no thanks to him. I also ended up with a kneecap fracture (lack of blood flow again) and found out that he put in too small of a spacer between metal parts and my knee gives out on me all the time. But at least I have my leg, I'm only 67 and can still get around. (with a little pain) Lori
