  • ACL Reconstruction in Combination with an Extra-articular Tenodesis

    Posted 2017-03-07 00:00:00 dun: Mahammad A. Tafida

    Rotatory instability of the knee is very often associated with the antero-posterior laxity in the ACL deficient knee and it is most probably caused by lesions of the anterolateral structures such the capsule and the anterolateral ligament. If underdiagnosed or undertreated with isolated ACL reconstruction this residual instability may lead to re-injury of premature arthritis.This manuscript focuses on the role of lateral extra-articular tenodesis (LET) in re-establishing dynamic stability when performed together with ACL reconstruction; then it describes our preferred surgical technique, which always associates ACL and LET, and discusses it with other surgical options described in ...

  • Anterolateral Complex Reconstruction: Who, When, and How?

    Posted 2017-02-24 00:00:00 dun: Mahammad A. Tafida

    Anterior translation and rotatory laxity of the knee joint is the result of an anterior cruciate ligament (ACL) rupture. The goal of ACL reconstruction is to restore normal knee biomechanics. Abnormal knee kinematics have been thought to be one of the primary factors in the progression toward osteoarthritis after ACL reconstruction. It has been demonstrated that even with a well-performed single or double bundle ACL reconstruction rotatory laxity can persist. This persistent rotatory laxity is one of the reasons to the recent international focus on the stabilizing role of the anterolateral complex in the ...

  • Magnetic Resonance Imaging Analysis of the Anterolateral Complex of the Knee

    Posted 2017-02-23 00:00:00 dun: Mahammad A. Tafida

    The anatomy of the lateral compartment of the knee is very complex, rich in different structures, and difficult to fully understand. Magnetic resonance imaging is the examination of choice for the diagnosis of musculoskeletal pathologies. This article reviews the historical perspectives and the normal and pathologic aspects of the anterolateral complex of the knee, consisting of the iliotibial tract, the lateral collateral ligament, the biceps tendon, and the anterolateral ligament, including the causative structures of the Segond ...

  • Biomechanical Role of Lateral Structures in Controlling Anterolateral Rotatory Laxity - The ITB

    Posted 2017-02-23 00:00:00 dun: Mahammad A. Tafida

    Recent research, focusing on rotatory knee laxity, has intrigued the whole orthopaedic knee community. First popularized by Hughston et al. peripheral knee injuries at the time of cruciate ligament rupture have regained more and more recognition, which has led to a better understanding of these injuries. Recent research has been focused on anterolateral rotatory instability, especially regarding which structures are responsible for the high-grade anterior subluxation of the lateral tibial plateau when ...

  • Ultrasonographic Visualization of Anterolateral Complex of the Knee

    Posted 2017-02-23 00:00:00 dun: Mahammad A. Tafida

    The anterolateral ligament (ALL) of the knee attracted much attention when a cadaveric dissection study using embalmed specimens described a discreet, constant ligamentous structure. Further multi-disciplinary studies of the anterolateral knee region revealed more intricate anatomy of this region, collectively best referred as the anterolateral complex (ALC) of the knee. An attempt has been made to further characterize and visualize this complex using different imaging modalities including magnetic resonance imaging (MRI) and musculoskeletal ...
