Combined Anterior and Anterolateral Stabilization of the Knee With the Hamstring Tendons.

ABSTRACT: Anterior cruciate ligament reconstruction allows good control of sagittal laxity but insufficient rotary laxity control. Our objective is to describe an original lateral extra-articular tenodesis using gracilis in addition to an intra-articular reconstruction using the semitendinosus in a short 4-strand graft. The principles are as follows: The femoral tunnel for intra-articular and extra-articular reconstruction is unique, the femoral attachment is posterior and proximal to the lateral epicondyle, the graft is under the lateral collateral ligament, and the tibial insertion is isometric from 0° to 60° between the Gerdy tubercle and the fibular head.

Minimally Invasive Combined Anterior and Anterolateral Stabilization of the Knee Using Hamstring Tendons and Adjustable-Loop Suspensory Fixation Device: Surgical Technique.

Project description:Despite the numerous techniques described regarding isolated anterior cruciate ligament (ACL) reconstruction, many authors have reported that residual knee rotational instability is not always eliminated. The combination of lateral extra-articular knee tenodesis and ACL reconstruction is an alternative surgical approach with very promising clinical results. The purpose of this article is to describe a reliable and reproducible technique of combined ACL reconstruction and lateral extra-articular knee tenodesis using a continuous looped hamstring tendon autograft. A 4-strand graft inside the joint and a 2-strand graft for the tenodesis are attached to 2 adjustable-loop button suspensory fixation devices.

Combined Anterior and Anterolateral Stabilization of the Knee With the Iliotibial Band.

Project description:Interest and knowledge on the anatomy, function, and biomechanical properties of the anterolateral ligament has led to the recognition of the importance of this structure in rotational control of the knee. This article describes a technique that allows for a combined anterior cruciate ligament (ACL) and anterolateral reconstruction, using an Iliotibial band (ITB) autograft. The graft is detached from the vastus lateralis from proximal to distal, at the center portion from ITB, preserving its distal insertion on the Gerdy tubercle. Its width is 1 cm for the distal part, used for the anterolateral ligament reconstruction, and 3 cm for the proximal part. An outside-in femoral tunnel is drilled respecting both the preferred favorable isometric femoral insertion site and the femoral ACL footprint. An ACL reconstruction combined with a lateral tenodesis with a continuous ITB graft respects the anatomical and isometric rules providing superior internal rotational control of the knee in comparison with a stand-alone ACL reconstruction.

Anterior Cruciate and Anterolateral Ligament Reconstruction Using Hamstring and Peroneus Longus Tendons: Surgical Technique Description.

Project description:The main objective of this study is to describe a surgical technique that combines intra- and extra-articular techniques using the semitendinosus, gracilis, and peroneus longus to perform reconstruction of the anterior cruciate ligament and anterolateral ligament. This technique offers a more stable, fast, low-cost, and widely accessible procedure and consists of drilling 3 tunnels-1 femoral and 2 tibial tunnels-in which the grafts are fixed with interference screws. The fact that the peroneus longus graft is long and thick allows for robust reconstruction of the aforementioned ligaments.

Associated Reconstruction of Anterior Cruciate and Anterolateral Ligaments With Single Asymmetric Hamstring Tendons Graft.

Project description:The anterior cruciate ligament (ACL) rupture is a common disease that accounts for 250,000 cases/year in the United States. The anterolateral ligament (ALL) has been suggested to be an important restraint for rotational instability, and its reconstruction provides a reinforcement to the ACL reconstruction in this aspect, especially in high-demand athletes and in knees with high-grade pivot shift. Different techniques for associated ACL and ALL reconstruction have been described, but the ideal technique remains unclear. Several facts of these techniques may entail a concern to the surgeon, such as the need for several grafts or several bone tunnels. A technique for associated ACL and ALL is presented, using a single hamstring tendons graft, which is prepared asymmetrically, leaving one-third of the length with single diameter and two-thirds with double diameter. A single femoral tunnel is created, using a screw for fixation and differentiation of the grafts. A suspension device is used for tibial fixation, allowing for length adjustment according to the graft's length. The objective of this Technical Note is to provide the orthopaedic surgeon with a resource for ACL and ALL reconstruction even with relatively short grafts, saving bone stock and avoiding the need for allografts.

Combined Reconstruction of the Anterior Cruciate Ligament and Anterolateral Ligament: Triple-Strand Braided Hamstring Graft for the Anterior Cruciate Ligament and Gracilis Strand for the Anterolateral Ligament With a Single Femoral Tunnel.

Project description:This article presents a surgical technique for combined reconstruction of the anterior cruciate ligament (ACL) and anterolateral ligament (ALL) of the knee using hamstring tendon graft. This approach involves creating a single femoral tunnel and using a triple-strand braided hamstring graft for the ACL and a strand of the gracilis tendon for the ALL. This technique aims to increase strength and improve knee stability, potentially reducing the risk of reinjury. The described method provides anatomic reconstruction of the ACL and ALL and allows for combined reconstruction with just 1 graft donor site. Another advantage is that the triple braided graft takes on a tape-like shape, mimicking the native form of the ACL and theoretically increasing biomechanical strength. Combined reconstruction of the ALL and ACL has shown excellent results in specific patient groups, reducing graft failure and improving outcomes in patients with a high risk of rupture. Thus, we describe a promising option for ligament reconstruction in cases of combined ACL and ALL injuries. This method may be a valuable alternative for orthopaedic surgeons, combining anatomic reconstruction with the use of a single donor site.

Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction.

Project description:Despite technologic advances in the surgical technique for anterior cruciate ligament (ACL) reconstruction, some patients continue to have rotational instability postoperatively. Recently, authors have reported the anatomic and functional characteristics of the anterolateral ligament (ALL), a structure that originates near the lateral epicondyle on the femur and inserts on the tibia between the Gerdy tubercle and the fibular head. Recent biomechanical studies have shown the ALL is an important stabilizer against anterolateral tibial rotation, and its reconstruction has shown excellent initial clinical results. Several techniques have been developed to try to anatomically address this structure in the setting of an ACL reconstruction. This article details a simple anatomic technique to reconstruct the ACL and the ALL of the knee using hamstring tendon autograft and maintaining the semitendinosus insertion.

Combined Intra- and Extra-articular Reconstruction of the Anterior Cruciate Ligament: The Reconstruction of the Knee Anterolateral Ligament.

Project description:We present a new technique for the combined intra- and extra-articular reconstruction of the anterior cruciate ligament. Intra-articular reconstruction is performed in an outside-in manner according to the precepts of the anatomic femoral tunnel technique. Extra-articular reconstruction is performed with the gracilis tendon while respecting the anatomic parameters of the origin and insertion points and the path described for the knee anterolateral ligament.

Combined Anterior Cruciate Ligament Repair and Anterolateral Ligament Reconstruction.

Project description:There has been a renewed interest in anterior cruciate ligament (ACL) repairs over the last decade with some early promising results in the right patient population. Additionally, the anterolateral ligament has been extensively studied and has recently been shown to have a protective effect on standard ACL reconstructions in a clinical trial. Given its protective effect on ACL reconstructions, we believe this phenomenon is also relevant to ACL repairs and can decrease rerupture rates. In this publication, we demonstrate a surgical technique for ACL repair using an internal brace combined with an anterolateral ligament reconstruction using a gracilis autograft.
