hi Sunshine
i had 2 knee surgerys about 4 years ago,,,right below the knee cap and small places aroud it are still numb,,,dr said it was due to athroscopic invasion and sometimes the numbness will go away,,alot of it did,,,,i know youve got alot of other pain in the theigh and leg,,im only trying to encourage the numbness around the knee,,yours may have been a total replacement ,,where they lay you wide open,,or artho,,,where you have 2 little scars,,,
