Using a Y‐Shaped Artificial Ligament for Posterolateral Corner Reconstruction in Multiligament Knee Injuries: A Surgical Technique

In multiligament knee injuries, reconstruction of the posterolateral corner is essential for restoring varus and rotational stability of the knee. Autografts and allografts are the current mainstays for posterolateral corner reconstruction; however, their use is associated with inherent limitations, including graft availability, insufficient size, and donor site morbidity. This technical note describes a surgical technique for posterolateral corner reconstruction using a Y‐shaped artificial ligament. This approach achieves anatomic reconstruction of the lateral collateral ligament and a functional, nonanatomic reconstruction of the popliteus tendon through a single femoral tunnel. The technique aims to provide reliable knee stability in a relatively minimally invasive manner while circumventing the limitations associated with traditional grafts.
