I don't know, but definitely the knee can refer to the feet and cause more pain.
There is a supplement that can help restore cartilage...it is called SAMe.

When my right knee gave out... I started this supplement in 1999 and it rebuilt my knee. It took time, but the dreaded knee replacement was not needed, and the left knee as predicted did not follow suit--- the doctor say 5 yrs or so for the left. I am here today, at 62, with both my knees!
