Abstract
Patients with complete anterior cruciate ligament (ACL) injury have different degrees of rotational (internal rotation) laxity. A residual pivot shift has been found to be positive in more than 15% of cases after an accurate ACL reconstruction. Improved understanding of the existence, function, and biomechanical role of the anterolateral ligament (ALL) in controlling rotational instability of the knee has redirected and refocused attention on a supplemental extra-articular reconstruction of the ALL in conjunction with the intra-articular ACL reconstruction so as to restore normal kinematics of the knee. This Technical Note describes a technique that allows for a combined ACL and ALL reconstruction using autogenous hamstring graft (semitendinosus and gracilis tendons). One femoral tunnel is used connecting the anatomic femoral attachment of the ALL on the lateral wall of the lateral femoral condyle to the anatomic femoral ACL footprint on the medial wall of the lateral femoral condyle. The remaining part of the graft is fixed to the proximal tibia midway between Gordy's tubercle and the head of the fibula. This Technical Note describes a technique of both ACL and ALL reconstruction with a continuous hamstring graft.
