[Blount's disease: a review of 8 cases (author's transl)].

The authors have reviewed eight cases of infantile tibia vara. All were treated operatively. Five patients were young children (less than 5 years old); they were treated by a single osteotomy into valgus and lateral rotation. Three children were older at the time of surgery. The deformity recurred in all of them and a second operation was required of elevation of the lateral tibial plateau and lateral epiplysiodesis. The authors emphasise the need for early correction of deformity to produce better mechanical function of the knee and balanced epiphyseal growth.
