Technique for Lateral Opening Wedge Distal Femoral Osteotomy Using Patient-Specific Instrumentation for Genu Valgum and Patellar Instability
Abstract
Recurrent lateral patellar instability poses a technical challenge to orthopaedic surgeons. Isolated soft-tissue procedures through medial patellofemoral ligament reconstruction or lateral release show unacceptably high failure rates. Lateral opening wedge distal femoral osteotomy addresses underlying bony malalignment and reinforces the soft-tissue procedure. Patient-specific instrumentation has shown utility in the setting of osteotomies with improved accuracy and reduction of intraoperative hinge fractures.
