Need some advice/feedback from others that have experienced severe knee injuries from training. I dislocated my knee about 7 weeks ago training for the Worlds and I've been in a full leg brace and crutches ever since. The knee injury was probably a direct result from overtraining, fatigue, jetlag (recently flew back from overseas) or a combination of all the above. A much taller & heavier opponent jumped guard on me and my knee buckled inwards tearing my LCL, PCL, & MCL. This is my first major injury during my 6 years of training. I've had both shoulders dislocated, hairline fracture on my foot, bulging disc L5 & others but this is by far the worst (cause I'll be out for at least 6 months from training). All the others injuries I've been able to come back with a toned down approach. What I want to know is how many of you roll on a daily basis with a hinged brace to prevent ligament damage? Has the brace injured your opponent during training? If you experienced any torn ligaments in the knee, did you choose to avoid surgery altogether and strengthen the supporting muscles around your knee? Do you feel any instability in the knee when wearing the brace & rolling? Any specific positions that causes pain in the knee (i.e. opponent puts the lockdown on your leg, etc...) Downtime sucks! I'm just thankful that my knee is still intact. Docs were telling me the high percentage of amputations resulting from knee dislocations and that I've been one of the "lucky" individuals. Nowadays, I still go to class on a daily basis to watch everyone spar and coach some of the lower belts. It's surprising how much you can improve your game by watching others roll. But just from these few weeks of observing from the sidelines and doing my research online, knee injuries have got to be public enemy #1 for BJJ and MMA.
