I have dislocated my left knee 6 times throughout my life, my right knee never gave me any problems until 2-3 years ago when the only way to stop the pain was to overextend my knee and force it to pop. Until it pops, I have awful pain that is on the inside on my knee and underneath my kneecap and sometimes I have shooting pain go from under my kneecap all the way up the center/middle of my thigh to my hip. My right hip is in the same position as my knee where I have to force it to pop to make the pain go away.
