title: Gerdy tubercle osteotomy in surgical approach of posterolateral corner of the knee.
abstract: Posterolateral corner (PLC) injuries of the knee are uncommon injury patterns that may result in significant degrees of functional disability. When surgery is necessary to address this injury a good knowledge of anatomy and a good surgical exposure is the mainstay. This report reviews the complex anatomy of the posterolateral corner (PLC) of knee and describes the osteotomy of Gerdy tubercle as a technical variant to approach this anatomical region. This surgical step allowing a good mobilisation of the multiple layers of ilio-tibial tract from distal to proximal makes an excellent exposure of the PLC structures with absence of morbidity.
