Knee pain have to do w/ binding position?

i remember an article i read somewhere but forgot what it said about this.

here is my problem: im 6ft 190lbs ride a 142, and have my bindings 1 in from all the way out, and both feet are ducked. well lately after a day of plenty heelside jumps my back leg knee hurts in the back of the knee, which doesnt bother me a whole lot, but then recently when i go switch (back leg knee now my front knee) will start hurting bad, but this time in the front of the knee towards the outside of the leg, i made it hurt pretty bad when i went heelside w2w 180 into the flats.

now i know some if not most of the problem is that when i land/go switch i want to put too much weight on my front foot, which straightens my leg which pressures my knee when chop or rollers come because im not fully absorbing them.

but i know some of the problem is the degree of duck to my bindings i think, or are the bindings out too far, and if its the duck to i brings the in towards center or duck them more towards ends?
