Single-Stage Distal Femur Osteotomy Using Patient-Specific Instrumentation, Lateral Meniscus Allograft Transplantation, and Lateral Femoral Condyle Osteochondral Allograft Transplantation.

The number of young athletes who present with combined meniscal and chondral deficiency with the need for joint preservation is increasing. These are challenging situations in which we must balance function with protection of our repair and/or reconstructive techniques but also afford our patients the opportunity to return to sport. Therefore, a careful understanding of mechanical alignment, meniscal repair and reconstructive strategies, and cartilage-restoration techniques is required. Here we present our technique for combined lateral meniscus transplantation with bone block, lateral femoral condyle osteochondral allograft transplantation, and medial closing-wedge distal femur osteotomy using patient-specific instrumentation.
