That looks nasty man! But fortunate that you're still with us! I screwed up my ACL when I was away for the weekend with my brothers on skis (stupid things) in a park. Couldn't straighten it for about 5/6 months and it still clicks when I move it, and ocassionally aches.
Thankfully, because I decided it was a good idea to carry on skiing on it, there was absolutely no pain if I put weight on it whilst my knee was bent in the position that I was skiing in, which meant that when I went boarding 2 months after the incident, it didn't hurt unless I fell.
Hope it goes well for you bro.
