Posterolateral Corner Repair With Internal Bracing and Peroneal Nerve Neurolysis

Posterolateral corner (PLC) reconstruction has been shown to be an effective treatment for PLC injuries. Acute anatomical repair of the PLC has the same potential to stabilize the knee; however, outcomes are less defined. Surgical repair minimizes graft harvest morbidity and allows for the maintenance of native tissue proprioception. Furthermore, augmentation with a flat-braided suture (SutureTape; Arthrex) portends additional repair strength and protection. The purpose of this Technical Note and video is to provide our preferred method of PLC repair in a patient with an acute knee dislocation and injury to the biceps femoris, lateral collateral ligament, iliotibial band, popliteofibular ligament, and the meniscocapsular attachment of the lateral meniscus.
