I have a banged up lateral collateral tendon on my left leg and I can still pull mission control without injuring or inflaming it. I actually injured it (possibly) while battling against a toe hold.
In my opinion, your knee joint is not meant to bend from side to side. There is no flexibility training for this, your tendon's just don't bend that way. You should be using your hips for flexibility pulling on your hip via the knee hug. If you are pulling your shin perpendicular to the flexation of your knee, you can injure yourself. I know it may look like people are doing that, but they aren't they are pulling downward with their shins, within the natural range of the knee joint using their hip flexibility to bring the shin close enough to clear the head.
