Arthroscopic Popliteus Reconstruction Using Anterolateral Portals

Posterolateral corner injury is associated with cruciate ligament injury. Even when the lateral collateral fibular ligament is intact and provides adequate stability in the coronal plane, a posterolateral rotational instability may still be present due to popliteus insufficiency. In this clinical context, arthroscopic popliteus reconstruction may provide sufficient posterolateral stability, while being less invasive than open posterolateral reconstruction. We propose a modified arthroscopic popliteus reconstruction using anterolateral portals to increase the toolbox of the arthroscopic knee surgeon when faced with partial posterolateral corner injury.
