i've always refferred to it as "my knee locking up"

what it is is when i bend to and have it in a un usual angle it will "lock" up... i have to stretch out and extend my legs and it will pop out...it's is nothing like dis-locating it...

any medical names?

i've had it since i was 5...(i'm 15 now)

my dad had it too when he was a kid...

i haven't had it too recent...the last time i got it was like9 months ago...


(it's very painful)

i have never consulted a doctor (my parents are cheap) LOL
