Hello Mark..I have a patella bone (a small bean shaped bone on the right side of my knee..showed up in xray after I had total knee replacement surgery). It hurts ( a quick, sharp pain when I walk, as I straighten my leg from the flex position.
I never had a problem with the patella bone before TKR...never knew I had a patella bone. I also have been told it is very unusual to have a patell bone. The doctors call my pain "the patella syndrome."
I'm interested in your reference to "nail patella". What is that. What does the nail refer to?? Also, what are you doing for pain relief?
