Medial Collateral Ligament Reconstruction of the Knee: The Modified Marx Technique With Adjustable-Loop Femoral Fixation and Posteromedial Corner Plication.

The medial collateral ligament serves as the primary stabilizer to valgus stress on the medial side of the knee and is the most commonly injured ligament in the knee. Medial collateral ligament reconstruction can provide improved stability and clinical outcomes for patients. Advancements in techniques, including the use of an adjustable-length-loop suspensory fixation device through a longitudinal incision, have been introduced in recent years. The purpose of this Technical Note and video is to provide a minimally invasive method for medial collateral ligament reconstruction with adjustable-loop femoral fixation and posteromedial corner plication.
