Arthroscopic-Assisted Lateral Extra-Articular Tenodesis With Knotless Anchor Fixation

Abstract

Recent studies have reported the biomechanical and clinical advantages of lateral extraarticular augmentation procedures including the modified lateral extra-articular tenodesis (LET) in the setting of anterior cruciate ligament reconstruction. LET has been shown to significantly decrease re-rupture rates in high-risk patients and decrease anterior cruciate ligament graft forces during pivoting loads and instrumented anterior laxity testing. Many variations of the modified LET approaches have been described. However, concerns including lateral hematoma, wound-healing complications, and increased operative time exist. This minimally invasive, arthroscopic-assisted approach using a knotless, all-suture anchor allows for direct visualization through a 2-cm incision and inherently decreases the morbidity associated with traditional LET techniques.
