  • Title: Infantile tibia vara.
    Author: Johnston CE.
    Journal: Clin Orthop Relat Res; 1990 Jun; (255):13-23. PubMed ID: 2347147.
    Abstract:
    Infantile tibia vara is a developmental condition producing progressive varus deformity of the knee in young children. It appears to have a worse prognosis in the predominantly nonwhite population seen with this condition in the United States than previous studies from Scandinavia would suggest. Early roentgenographic diagnosis is critical, since toddlers can have infantile tibia vara at an early stage instead of physiologic genu varum. Aggressive bracing is appropriate treatment until age three years. Correction to valgus alignment with upper tibial osteotomy predictably can produce complete resolution of the condition if performed by age four years. After that age, the procedure becomes less effective. Prognosis for Langenskiold Grade IV disease is guarded at best, regardless of age, because the physis behaves as if effective growth arrest has already occurred. Young patients with Grade IV or greater lesions should have corrective osteotomy combined with a physeal procedure to attempt restoration of growth in the medial physis. Early effective treatment can prevent permanent intraarticular incongruity.
