Multiligament Knee Injury With Common Peroneal Nerve Rupture: Single‐Stage Reconstruction of the Anterior Cruciate Ligament, Posterolateral Corner, and Common Peroneal Nerve Graft

Multiligament knee injuries (MLKIs) are rare injuries that can result in devastating outcomes and functional impairment, especially in the setting of concomitant peroneal nerve injuries. Incidence of common peroneal nerve (CPN) injuries in MLKIs or knee dislocations ranges from 10% to 40%, with significant morbidity associated, especially in the setting of complete rupture. Treatment for MLKI with associated CPN injury depends on the degree of ligamentous and nerve injury. Options for the MLKI include nonoperative, repair, or reconstruction. Options for the CPN include included observation, neurolysis, direct nerve repair, and nerve grafting. In this Technical Note and associated video, we present a technique for an anterior cruciate ligament and posterolateral corner reconstruction with nerve reconstruction in the setting of a multiligament knee injury with complete CPN rupture.
