I wish we could get surgeons to inform patients of possible foot numbness and nerve danage as one of the tkr side effects. My surgeon denied any connection when I tried to tell him about my symptoms. When I came out of surgery my toes were totally numb. It turns out I had some damage to the peritoneal nerve and the numbness kept decreasing as I became more active. I am a year and half out from surgery. I try to be consistently be conscious of moving my toes up and down and flexing my toes as much as possible during the days. I broke my foot when I was at a year into recovery and had to start all over again after immobilizing the foot for months while the bone healed. It seems like the key is to keep movement in the foot as much as possible. February will be two years out from surgery and it is pretty minimal now.
