I had both knees replaced 10 years ago. Best thing I ever did at the time. I was very active and my knees wore out with skiing, biking and running. The surgery got me back to everything except running. I am now 69 years old. I had a little numbness in both my feet prior to the surgery and it got a little worse every year after. A year ago both feet dropped and I am 80 % numb below my knees in both legs. I have little balance and need braces and a cain to walk. Falling is a problem. The good news is I have no pain. Is my condition due to the surgery 10 years ago? I think the knee replacements had some effect on my condition but the doctors aren't 100% sure. I have tried a number of remedies to try to get feeling back with no success. Anyone out there have any ideas?
