Anterior open-wedge hepta-lateral osteotomy for severe post-traumatic genu recurvatum: a case report and review of the literature.

Severe post-traumatic genu recurvatum is an uncommon condition in orthopedics. The typical symptoms are pain, weakness, and instability. For severe and symptomatic genu recurvatum patient, the surgical correction should be performed to relieve symptoms and prevent progression of deformity. Many procedures were proposed to treat this condition, but there are some complications such as patella baja, secondary deformity, skin complication, and inadequate correction. Most of the procedures need an additional procedure such as tibial tuberosity transfer to correct the patellar height. In this case, the authors report a new technique in which the osteotomy was performed near the center of rotation angulation. And, the correction did not influence the patellar height.
