When limb lenghtening, how exactly does bow legs correction work? There are many methods for it, but from what I've read they all involve an osteotomy (cutting and reshaping the bone) of either the tibia, the femur, or both (if >12 degrees).

So my question is, does it reduce the overall gain (or put any restrictions on the lenghtening amount) during limb lenghtening? If so, by how much?
