Autologous Single Semitendinosus Anatomical Posterolateral Corner Reconstruction With Adjustable-Loop Cortical Suspension Devices.

ABSTRACT: We present our surgical technique for the reconstruction of the posterolateral corner of the knee. It is a tibia- and fibular-based reconstruction technique. Most of these procedures require the use of 2 tendons (autograft or allograft). In our technique, a single semitendinosus tendon is required, making the procedure more suitable if the surgeon prefers the use of autograft or when there is no access to a tissue bank. This is even more important in the setting of multiligament knee injuries. The most defining feature of this modification is the possibility of achieving the desired graft tension in a progressive and independent way, due to the use of 3 adjustable-loop cortical suspension devices.

Anatomic Posterolateral Corner Reconstruction Using Single Graft Plus Adjustable-Loop Suspensory Fixation Device.

Project description:The original description of the LaPrade technique for anatomic posterolateral corner reconstruction addresses the 3 main stabilizing structures: the fibular collateral ligament, the popliteus, and the popliteofibular ligament. The use of two separate grafts (originally described with a tendo-Achilles allograft) may restrict the utility of the technique when sources of allograft may be limited and autografts must be used, particularly in the context of multiligament reconstruction. We present a modification of the technique, in which an adjustable cortical button is used for tibial fixation, which allows for the use of a single graft while maintaining the ability to independently tension the popliteus, popliteofibular ligament, and fibular collateral ligament limbs of the graft.

Anatomic Posterolateral Corner Reconstruction Using Semitendinosus and Gracilis Autografts: Surgical Technique.

Project description:An anatomically based posterolateral corner (PLC) reconstruction has emerged as a viable and clinically effective surgical technique for midsubstance ligamentous injuries in both the acute and chronic settings. There are several surgical techniques for PLC reconstruction; however, the classic anatomic reconstruction technique (LaPrade technique) is now considered the gold standard and was originally described using an Achilles tendon allograft. In this article, we describe a modified LaPrade autograft technique, in which the same tunnel position, graft passage, and fixation are used to reproduce the 3 primary stabilizers of the PLC. Instead of allografts, hamstring autografts are used while tunnel diameters and fixation devices are adapted to them. With the use of autograft tendons, difficulties related to graft length or asymmetry are encountered. We consider this technique a good alternative for an anatomically based PLC reconstruction, especially given the lower availability and higher cost of allograft tissues in several countries.

Posterolateral Corner Reconstruction: Modification of the LaPrade Technique Using Autologous Hamstring Tendon Grafts: "The Popliteofibular Loop".

Project description:Posterolateral corner (PLC) injury is a significant cause of knee instability. In recent years, a better understanding of the anatomy and biomechanics of the PLC structures has led to significant advancements in the surgical treatment of this injury. Anatomical reconstruction techniques, particularly the LaPrade technique, have shown promising results. However, in some settings, the reliance on allografts limits the feasibility of this technique, prompting surgeons to seek reproducible alternatives that use autologous grafts, eliminating the need for tissue banks. The purpose of this Technical Note is to describe a modification of the LaPrade technique for PLC reconstruction using autologous hamstring tendon grafts. The surgical technique is described to ensure reproducibility, with particular emphasis on the proposed modifications: the use of autologous grafts (gracilis and semitendinosus tendons); the configuration in which they are used to increase the thickness of the reconstructed structures; and the exclusive fixation with widely available interference screws.

Double Vector: A Combined Biomechanical and Anatomical Posterolateral Corner Reconstruction Technique.

Project description:Posterolateral corner (PLC) injuries are complex knee injuries that are becoming increasingly frequent. Often undiagnosed and underestimated, a systematic diagnostic workup is necessary to assess the severity of PLC injury in order to then be able to select the proper surgery approach. Anatomical and nonanatomical PLC-reconstruction techniques have been described. In this Technical Note, we describe our technique of biomechanical reconstruction of PLC in case of severe posterolateral rotational instability.

Anatomic Posterolateral Corner Reconstruction.

Project description:Posterolateral corner injuries represent a complex injury pattern, with damage to important coronal and rotatory stabilizers of the knee. These lesions commonly occur in association with other ligament injuries, making decisions regarding treatment challenging. Grade III posterolateral corner injuries result in significant instability and have poor outcomes when treated nonoperatively. As a result, reconstruction is advocated. A thorough knowledge of the anatomy is essential for surgical treatment of this pathology. The following technical note provides a diagnostic approach, postoperative management, and details of a technique for anatomic reconstruction of the 3 main static stabilizers of the posterolateral corner of the knee.

Combined All-Inside Anterior Cruciate Ligament Reconstruction and Minimally Invasive Posterolateral Corner Reconstruction Using Ipsilateral Semitendinosus and Gracilis Autograft.

Project description:The anterior cruciate ligament (ACL) is the most commonly injured knee ligament, particularly among adolescents and young adults. Unrecognized posterolateral laxity is understood as a major cause of ACL reconstruction failure, and concomitant injury to the posterolateral corner (PLC) is prevalent and underdetected. We advocate screening all ACL-deficient knees for PLC injury and present a technique combining minimally invasive PLC reconstruction with anatomic all-inside ACL reconstruction. The combined procedure uses only the ipsilateral hamstring tendons representing a major surgical advantage over traditional management approaches. The semitendinosus is quadrupled and attached to 2 adjustable suspensory cortical fixation devices to form the ACL graft. The gracilis tendon is looped through the fibula head and secured in a single femoral tunnel for the PLC reconstruction via 2 minimally invasive incisions. The use of a single femoral PLC tunnel combined with a single femoral ACL socket minimizes the risk of tunnel convergence.

Anatomic Posterolateral Corner Reconstruction With Autografts.

Project description:Anatomic posterolateral corner reconstruction reproduces 3 main structures: the lateral collateral ligament, the popliteofibular ligament, and the popliteus tendon. The LaPrade technique reproduces all 3 main stabilizers. However, it requires a long graft, limiting its indication to clinical settings in which allograft tissue is available. We propose a surgical procedure that is a modification of the LaPrade technique using the same tunnel placement, hamstring autografts, and biceps augmentation when necessary. It relies on artificial graft lengthening provided by the loop of the suspensory fixation device fixed at the anterior tibial cortex. The final reconstruction reproduces the popliteus tendon with the bulkiest end of the semitendinosus; the popliteofibular ligament with a strand of the semitendinosus and a strand of the gracilis; and the lateral collateral ligament with a strand of the semitendinosus and a strand of the gracilis, which can also be augmented with a biceps strip.

Knee Posterolateral Corner Reconstruction with a Single Tendon.

Project description:Knee posterolateral corner (PLC) injuries are troublesome conditions and are always involved in complicated knee-ligament injuries. Various surgical techniques have been reported to address these conditions, in either an open or an arthroscopic manner. However, a simple and effective method is still being pursued. We introduce a mini-invasive PLC reconstruction technique in which a single tendon is used to reconstruct the lateral collateral ligament, the popliteofibular ligament and the popliteal tendon simultaneously. The critical points of this technique are proper location and creation of the tibial, fibular and femoral tunnels, proper passing and setting of the tendon graft, as well as protection of the peroneal nerve. Our clinical experience indicates that this technique is easy to perform and effective. We consider that the introduction of this technique will provide more reasonable options when PLC reconstruction is indicated.

Minimally Invasive, Arthroscopic-Assisted, Anatomic Posterolateral Corner Reconstruction.

Project description:As the anatomy and biomechanics of the posterolateral corner (PLC) of the knee have become better understood, the importance of the PLC's proper function has become a more frequently raised subject. Misdiagnosed chronic posterolateral instability may lead to serious consequences, including cruciate ligament reconstruction graft failure. It has been proved that high-grade PLC injuries need to be treated operatively. Surgical approaches vary, and techniques are still developing. Considering avoidance of an extended surgical approach and minimizing the risk of common peroneal nerve or popliteal artery injuries, we developed the minimally invasive, arthroscopic-assisted, anatomic PLC reconstruction.

Anatomical Double-Bundle Medial Patellofemoral Ligament Reconstruction With Autologous Semitendinosus, a Single Patellar Tunnel Technique.

Project description:Patellofemoral instability is one of the knee problems that can be found in up to 3% of knee injuries, especially in younger aged females. Recent biomechanical studies showed that the main soft tissue stabilizer for patellofemoral stability is the medial patellofemoral ligament (MPFL). More than 200 articles on MPFL reconstruction have been published. Some surgical techniques create multiple holes in the patellar area that may increase the risk of patellar fractures. This technique that we present here attempts to reduce the chance of patella-related complications, while maintaining stability of the reconstructed construct, reducing the use of a lengthy tendon graft within the patella and covering the footprint at the border of the patella closed to the native anatomy of the MPFL.
