[JSDSKI]

John - if you're knock-kneed its more likely you should be fitted with a custom footbed. This will recenter your knee over your foot and give a full range of edge to edge transition. Adjusting the cuff won't change the relationship of your hip, leg, knee, and foot to the sweet spot on the ski - it just centers the cuff around the lower leg. If the lower leg is at an angle (knock kneed) to the ski - you are still going to be riding the inside edge. Go to a real bootfitter, spend the extra bucks, and your skiing will be easier and more improved than you can imagine.

Actually, you should probably get new boots fitted first so your physical alignment doesn't affect your ski choice.... you can make a poor ski work with great fitting boots. But even a great ski will feel like crap with poorly fit boots.
