Hi. I had a tkr on my right knee and three months later felt numbness in both my feet. So I don’t think it was anything the surgeon did. Seem to subside. Move on to 10 months later my left knee Done and 2 weeks later both feet went numb in the balls of my feet and toes. Seems it may be my gait with my flat overpronated feet after surgery. Decompression on the tarsaltunnel 3 times. Nothing changed. Very debilitating 3-4 yrs later.... 😪😪
