Isometric Anterolateral Ligament Reconstruction Using the Semitendinosus Tendon With Suspensory Tibial Fixation

The anterolateral ligament (ALL) plays an important role in isolated anterior cruciate ligament reconstruction by providing rotational stability in a combined anterior cruciate ligament and anterolaterally injured knee. Although the ALL has been difficult to characterize anatomically, it originates near the lateral epicondyle of the distal femur and inserts into the proximal tibia between Gerdy's tubercle and the fibula head. Here, we describe an isometric ALL reconstruction using the semitendinosus tendon and an adjustable length loop suspensory tibial fixation. With this technique, it is possible to provide good stability and satisfactory results for patients with rotational instability of the knee.
