Femur length should always be taken into consideration when getting a fit OR custom bike. I always get that measurement. It is pretty much the baseline of the frame design. Oddly, I find that a lot of builders do not.
I sound like a broken record on this point, but a lot of very small stock bikes come with fairly or extremely steep seat angles. This is to reduce reach, but is a magic trick that really creates more problems than it helps. If you have a long femur and are set up on a bike with an overly steep seat angle, you have fairly good odds of developing knee problems. If you have front of the knee pain on your small stock bike, look at your knee's position over the bottom bracket/crank before all else. If you want to know where your position is relative to "neutral"/"ideal" pm me and I will explain how. It's not hard.
