Biomechanical Role of Lateral Structures in Controlling Anterolateral Rotatory Laxity: The Anterolateral Ligament

Anatomic Combined Anterior Cruciate Ligament and Antero-Lateral Ligament Reconstruction Using Autologous Gracilis and Semitendinosus Graft With Single Tibial and Femoral Tunnel

“…Moreover, biomechanical studies confirmed that the anterolateral complex (ALC) acts as an important anatomical constraint against tibial internal rotation. 8 Thus, undiagnosed and untreated ALC injury have been claimed to be responsible for residual anteroposterior and rotational instability that may affect up to 25% of patients after isolated ACL reconstruction. 9 , 10 Indeed, recent biomechanical studies confirmed the reduction of in situ forces on ACL graft after LET (lateral extra-articular tenodesis).…”

Arthroscopic-Assisted Lateral Meniscal Allograft Transplantation With Open Ligamentous Extra-Articular Tenodesis

“…Rotational stability is another major concern in ACL grafts, and a significant proportion of patients report persistent rotatory instability after ACLR. 4 Recent biomechanical work has demonstrated that the anterolateral structures of the knee, including the anterolateral ligament, fibular collateral ligament, and Kaplan’s fibers (which connect the distal iliotibial band [ITB] with the lateral condyle of the femur) all contribute to rotatory stability, 5 and ligamentous extra-articular tenodesis (LET) procedures concurrent with ACLR significantly decrease forces on the graft. 6 This information suggests LET procedures may be used to protect the ACL graft from rotational forces, 4 particularly in patients with deficiency of the lateral meniscus.…”
