Abstract:
This article aims to provide a new surgical technique for rotational instability in the setting of anterior cruciate ligament rupture. Two main groups of surgical procedures can be identified in the treatment of anterolateral knee instability: lateral extra-articular tenodesis and anterolateral ligament reconstruction. Although the importance of anterior cruciate ligament reconstruction in anterolateral complex injuries is well known, the superiority of lateral extra-articular tenodesis over anterolateral ligament reconstruction or vice versa has not yet been shown. Both techniques show improved outcomes and reduced graft failure rates. The presented procedure can be considered a modification of the technique first described by Lemaire. Better tensioning can be achieved through cortical suspension by identifying the anisometric point on the lateral femur and performing a medial pullout on the femoral side. The advantages of this technique are better fine-tuning and tensioning, less invasiveness, and adjustable cortical fixation, which allows for a precise, incremental tensioning of the graft, ensuring circumferential healing of the graft within the socket and reducing the risk of graft laceration, which may happen with interference screws. Internal bracing provides excellent contact pressure between the femoral button and femoral cortex, ensuring that adequate tensioning is applied to the graft.
