im missing the notch in the end of my femur for the knee cap to ride in.....one of the specialists ive seen says that while there is a wide variation between people im about as close to flat as he has seen and my knees are bout like a bowling ball on a table going where ever in the hell they want....no cool story, no injury, bad roll of the genetic dice and i came up snake eyes......2 out of 3 siblings have similar problems...
