Interlinked Hamstrings for Combined Anterolateral and Anterior Cruciate Ligament Reconstruction: A Novel Technique for ALL.

Abstract

Anterolateral ligament (ALL) reconstruction provides rotational stability in patients undergoing anterior cruciate ligament (ACL) reconstruction. The aim of this study was to assess the outcome of patients who underwent combined ACL and ALL reconstruction with a novel anatomic technique using hamstring tendon autograft and fixed loop suspensory device. From 2016 to 2018, 25 patients who underwent combined reconstruction of ACL and ALL in our Institution were evaluated retrospectively. International Knee Documentation Committee (IKDC) Score, Tegner Lysholm Knee Score, grade of pivot shift was assessed at a final follow-up. Mean follow-up was 31.5months (28-42). Mean IKDC (81.5) and Tegner Lysholm (82.8) Knee Scores improved significantly at a final follow-up, with all knees demonstrating negative pivot shift. All patients had good outcomes at 2years follow-up with no graft failure and with no residual instability. ACL and ALL reconstruction using this technique described for the anterolateral instability of the knee was satisfactory in our patients. This technique is simple, easily reproducible and avoids additional implants for ALL in the tibia. IV.
