Proximal tibial osteotomy for genu recurvatum. A review and case report.

Genu recurvatum may be due to weakness of the muscles that stabilize the knee, with secondary bone changes. The more common etiology is primary bone deformity of the proximal tibia, which may result from multiple causes. An operation is described for the anatomical correction of the latter type. A corrective opening wedge osteotomy is maintained with full thickness bicortical iliac triangular wedges. This technique has been successfully used in one patient who has been followed for 12 years.
