QuoteI’m confused about if this would naturally be the case. I don’t think there’s a typical knee height. It’s not like there’s a typical rule that someone has X knee height if they have Y leg length. Also I might be wrong but I would think that that lengthening the femurs is above the knee so it wouldn’t raise it.
I think he meant his knee level would look too low if he lengthened femurs, not too high. In general there is a normal ratio between femur and tibia length, maybe 5:4 or thereabouts, so if you lengthen one segmet by a lot you'll look disproportionate to a trained or critical eye.
