Flexion femoral osteotomy with tightening of soft tissues in front of the hip in treatment of genu recurvatum after poliomyelitis

Twenty six poliomyelitis patients with genu recurvatum, were treated by supracondylar femoral osteotomy with anterior open wedge and bone grafting from ipsilateral iliac bone, combined with upward and posterior displacement of the muscles attached to the outer table of the iliac bone. The average age was 14.6 years. The average angle of recurvatum before operation was 39 degree. Fifteen of the patients were orthosis dependent. After a follow up period of at least 2 years, 88.4% had regained significant improvement in appearance, walking ability, and orthosis discarded
