N2 - In a retrospective review of 74 tibial osteotomies performed for Blount disease, the patients were divided into three groups based on age and treatment. Group A (26 osteotomies), 4 years old or younger, and group B (34 osteotomies), older than 4 years, were treated the same with osteotomy and crossed pins. Group C (14 osteotomies), older than 4 years, was treated with osteotomy and external fixator. At 6 years of follow-up, the recurrence of varus deformity was 46%, 94%, and 72% in groups A, B, and C, respectively. There was no correlation between recurrence of varus deformity and preoperative deformity angle or degree of surgical correction. Fixation with crossed pins or external fixator was not a factor. Surgery at 4 years old or younger and correction of the postoperative deformity angle in valgus may obviate recurrence of varus deformity in Blount disease at long-term follow-up.
