A retrospective analysis of treatment and outcomes in patients with late onset tibia vara.
This retrospective analysis included 36 patients who presented with late-onset tibia vara during a 15-year period. Mean patient age at presentation was 12.8 years. Seventy-eight percent of patients were male, 78% were black, and 72% presented with unilateral deformity. Mean initial varus was 21 degrees with 5.8 degrees at the femur and 12.3 degrees at the tibia. Surgical correction was performed in 31 patients; 5 patients refused surgery. Patients who had osteotomies had a higher rate of complications than those treated with stapling. Epiphyseal stapling has unpredictable results in patients with late-onset tibia vara and is only a temporizing procedure in approximately half of cases. None of the treatments resulted in optimal knee function or alignment, and the long-term prognosis for late-onset tibia vara is guarded at best.
