Open Anatomic Reconstruction of the Posterolateral Corner: The Arciero Technique

Arthrosc Tech. 2020 Sep 2;9(9):e1409-e1414. doi: 10.1016/j.eats.2020.05.022. eCollection 2020 Sep.


The posterolateral corner (PLC) is an important stabilizer of the knee. This complex of ligaments and tendons functions as the primary restraint to varus and posterolateral rotation of the knee. Injury to the PLC can result in chronic instability, a varus-thrust gait, and early arthrosis of the medial compartment of the knee if left untreated. Several techniques have been designed to address injuries of the PLC. Over the last 30 years, our understanding of the posterolateral corner as well as its operative reconstruction evolved. This evolution has attempted to refine what is an "anatomic" reconstruction. With more improved techniques and new, innovative fixation devices, we hope to make a more favorable repair for recreating the native stability of the posterolateral corner.
