I had a cold, numb and tingly foot and purple toes right after my right TKR and was told it was normal by several, but 1 Dr finally listened to me(50 days later). I had an ABI test done which showed low pressure in my leg from the knee down. Which sent me to a cardiologist and then had an angiogram that showed the popliteal artery that supplies the blood to the leg/toes was totally pinched closed. Then had artery surgery which opened the artery and turned my toes pink again, but did not totally get rid of ALL the numbness and tingling. Was told because of the lack of blood to my foot I could have cell and tissue damage. I had nerve tests done that showed nerve damage to the main nerve that goes down the leg. Been 18 months and was told it might not ever heal or could take 3 yrs. Good luck.

I would like to know how many people who received a TKR and acquired foot numbness soon after ALSO drank alcohol over the suggested safe two drinks per day for some years. I myself drank four per day for approx. ten years (retired) and am thinking I damaged/weakened nerves so as to make them vulnerable to disturbance of a TKR operation. Just a thought after reading all about alcohol neuropathy. Note: Something I never heard of before!
