basicly a few years ago i broke my right knee cap and shin pretty bad, if it had been one more chip or broken part of the bone i would have needed an operation. luckily i didn't need one so they put my leg in cast for eight weeks, the day i had the cast taken off my leg was still very weak, but stupid me ran and tripped over a drain and rebroke my knee, not as bad as the first time, but still !

any way that happened nearly ten years ago and my doctor said my right leg will be slightly weaker than the right after the two breakes which i guessed my self. but for over five to six years i have had terrible pain in my knee like its something grinding my knee cap. i went to my doctor had scan and exrays but i never toke it any further because the pain goes away for a few months but then comes back.

basicly im hating this grinding pain, it hurts to bend and even standing up for to long kills my knee it swells terribly some times. i cant take it what could it be?
