^a2 hips had been redislocated after CR.

^b1 hip had been redislocated after CR and 1 hip after anterolateral OR.

^cThere were patients who had repeated femoral osteotomies (twice, n = 2; 3 times, n = 1) before skeletal maturity.

^d1 patient had had pelvic osteotomy twice before skeletal maturity.

^eThere were patients who had repeated femoral osteotomies (twice, n = 1; 3 times, n = 1) or repeated pelvic osteotomies (twice, n = 1) before skeletal maturity.

CR = closed reduction under general anesthesia; OR = open reduction.
