INCORRECT

The correct answer is:

FALSE:

Zoints and MacEwen reviewed the cases of seven children with post-traumatic tibial valga. In six of these patients spontaneous correction occurred. Although improvement was seen in the metaphyseal diaphyseal angle in all cases in which spontaneous correction occurred, compensatory overgrowth of the lateral distal physis was also seen. Valgus deformity in excess of 15 degrees is less likely to spontaneously improve according to Jackson.
