Non-Standard Biomechanics

My hips are rotated at a 45% angle outward. I was born that way. It never caused me too many problems. I could never be a sprinter, but I did fine as a lineman. I have to compensate to walk and run normally. Basically it takes roughly twice the energy for me to run a mile than if my hips were angled straight forward like everybody else. The only people who ever noticed were football coaches and drill instructors. In any case, do you think any form modifications would help with squats and deadlifts? The squat stance from starting strength feels perfectly normal as it is close to where my feet want to be when I stand relaxed. The only reason I am concerned is because after a heavy squat session, I get some sharp pain for a day or two near my knees and the pain happens whenever I rotate my ankles/hips to the straight forward direction.

Video of your squat?

I figured it out. I looked at the back of my leg today and it looks like somebody hit me with a hammer or something. Must have been 3 weeks ago or something because all that nasty grren part of the bruise is gone and just the purple is left. I don't remember it, but who knows. Either way it must be healing. I am sure it will go away.
