The correct answer is:
The limb malalignment is often dependent upon when the metabolic abnormality occurred. If it is before two years of age a varus deformity will occur, after two years age a valgus deformity is most likely. The type of deformity is probably dependent on the child's underlying alignment which explains the age relationship since young children have normal varus knee alignment while older children have a normal valgus alignment.
