Exactly how I blew my ACL

For those of you that have asked, I thought I'd post the video that shows exactly what I was doing when I blew my ACL. As you watcht this video, I would have been the guy in the red/black top. At 1:38 in the video he taps due to the pressure from the submission. Because I was pretty flexible, I did not tap. As soon as I realized that I didn't have to tap, I attempted to yank my right leg out of the lockdown that he had on it with his legs. Because my ACL was already torn pretty significantly ( a fact that I did not know at the time), and because he held the lockdown perfectly and straightened his legs to tighten it down even more when I tried to pull out ( the perfect response), my knee dislocated momentarily and blew the ACL. This would not normally have been the outcome and I beleive that if I had a proper knee at the time, it wouldn't have been the case. I thought this video would better illustrate what I've tried to explain to many of you.
