Correction of bony genu recurvatum combined with ligamentous instability of the knee: three case reports.

We report our experiences for treating the bony genu recurvatum combined with ligamentous instability that needed both osteotomy and ligament reconstruction in three cases. The bony component was corrected according to normal tibial slope, patellar height and limb length. After the osteotomy, we reevaluated the instability of the knee and performed ligament reconstruction if the patients had ligamentous instability even though the osteotomy was done.
