Abstract:For genu recurvatum deformity after tibial fracture, precise correction osteotomy is necessary to acquire a good clinical outcome. No report on genu recurvatum has evaluated precise preoperative planning with image-processing software for three-dimensional (3D) design and modeling. We herein report a case of osseous genu recurvatum treated by anterior opening wedge osteotomy according to precise preoperative 3D simulation. This is a useful tool for precise correction of osseous deformity.

Genu recurvatum deformity is evaluated as the angle between the lines of the anatomical axis of the distal part of the femoral shaft and that of the tibial shaft (x). (a) Normal side shows an 11 ° extension. (b) Injured side shows a 24 ° genu recurvatum deformity. The angle between the lines of the anatomical axis of the distal part of the femoral shaft and the plane of the tibial plateau (y) is identical to that of the normal side, and the posterior tilt angle of tibial plateau (90 ° minus z) is −6 °, which is 13 ° smaller than that of the normal side.
