Late... But I have knee dislocation problems too
First time I ever dislocated it, it stayed dislocated until I went to the doctor to get it popped back in. I know it seems like a pussy thing to do, but my knee was out of socket and I needed immediate help. I have dislocated it around 5 times after that, each time it popped back in after a few seconds. It's a really weird feeling.
I came across this thread because just about 10 minutes ago I fucked it again, and am afraid to enter the slope style comp at my mountain tomorrow. Probably not a great idea, and I'm fucking pissed.
