Late-onset tibia vara

Fifteen children with late-onset tibia vara were studied. There were seven unilateral and eight bilateral cases. Eleven children were male, four were female and 13 were black; 14 were obese. All had a history of gradually progressive genu varus (average onset 11 years); 12 had preoperative knee pain. The average age at surgery was 12 years, with a preoperative tibiofemoral angle of 14 degree varus. The average follow-up was 4 years 4 months. The average tibiofemoral angle at follow-up was 0 degrees. There were 15 good, two fair, and six poor final results.
