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

ABSTRACT: 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 With Autogenous Peroneus Longus Y Graft Construct.

Project description:The posterolateral corner of the knee is composed of the fibular collateral ligament, popliteus tendon, and popliteofibular ligament, which provide varus and rotational stability to the knee. An anatomic technique reconstructs these structures through 2 femoral sockets and 1 tibial and 1 fibular tunnel. This reconstruction can be performed using a peroneus longus autograft that is prepared as a Y construct. The peroneus longus autograft is preferred because it provides adequate length and diameter for the entire reconstruction. Initially, the doubled loop of the Y is passed into the tibial tunnel and fixed with an adjustable cortical button. The shorter limb of the Y is used for reconstruction of the popliteus tendon. The longer limb of the Y is passed from posterior to anterior through the fibular tunnel and is fixed in the tunnel with an interference screw to re-create the popliteofibular ligament. The remaining graft is then shuttled deep to the iliotibial band and superficial to the popliteus tendon, into the femoral socket, to re-create the fibular collateral ligament.

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.

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.

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.

Open Anatomic Reconstruction of the Posterolateral Corner: The Arciero Technique.

Project description:The posterolateral corner (PLC) is an important stabilizer of the knee. This complex of ligaments and tendons functions as the primary restraint to varus and posterolateral rotation of the knee. Injury to the PLC can result in chronic instability, a varus-thrust gait, and early arthrosis of the medial compartment of the knee if left untreated. Several techniques have been designed to address injuries of the PLC. Over the last 30 years, our understanding of the posterolateral corner as well as its operative reconstruction evolved. This evolution has attempted to refine what is an "anatomic" reconstruction. With more improved techniques and new, innovative fixation devices, we hope to make a more favorable repair for recreating the native stability of the posterolateral corner.

Anatomic Reconstruction of the Posterolateral Corner: An All-Arthroscopic Technique.

Project description:Injuries of the posterolateral corner (PLC) of the knee lead to chronic lateral and external rotational instability. Successful treatment of PLC injuries requires an understanding of the complex anatomy and biomechanics of the PLC. Several open PLC reconstruction techniques have been published. It is understood that anatomic reconstruction is superior to extra-anatomic techniques, leading to better clinical results. An open, anatomic, fibula-based technique for reconstruction to address lateral and rotational instability has been described. However, when an open technique is used, surgeon and patient are faced with disadvantages, such as soft tissue damage or exposure of vulnerable structures. Few arthroscopic techniques for tibia- or fibula-based reconstruction of rotational posterolateral instability have been described. A complete arthroscopic stabilization of the combined lateral and posterolateral rotational instability of the knee has not yet been described. We therefore present the first all-arthroscopic technique for complete PLC reconstruction, based on an open technique described previously. All relevant landmarks of the PLC can be arthroscopically visualized in detail, allowing safe and effective treatment of PLC injuries.

Arthroscopic Identification of the Knee Posterolateral Corner Structures and Anatomic Arthroscopic Posterolateral Corner Reconstruction: Technical Note - Part 1.

Project description:Arthroscopic assessment of posterior compartments of the knee and the posterior aspect of the proximal tibial and fibula is challenging because of the relative proximity of the neurovascular bundle. This Technical Note describes a reproducible arthroscopic surgical approach in a cadaveric model that aims to identify and expose the popliteus tendon, posterior fibular head, fibular collateral ligament popliteal fibular ligament, biceps femoris tendon, and peroneal nerve.

Arthroscopic Identification of the Knee Posterolateral Corner Structures and Anatomic Arthroscopic Posterolateral Corner Reconstruction: Technical Note - Part 2.

Project description:Posterolateral corner injuries are complex injuries, and their therapeutic management varies from one individual to another. Biomechanical studies demonstrate that anatomic posterolateral corner reconstruction restores knee kinematics better than nonanatomic reconstruction. The purpose of this report is to describe an all-arthroscopic procedure for anatomic posterolateral corner reconstruction.

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.

A Technique of Superficial Medial Collateral Ligament Reconstruction Using an Adjustable-Loop Suspensory Fixation Device.

Project description:This report describes superficial medial collateral ligament reconstruction of the knee using a novel method of graft fixation with the ACL Tightrope RT (Arthrex, Naples, FL). After tibial fixation with either a standard interference screw or staple, femoral fixation of the semitendinosus tendon is performed with the adjustable-loop suspensory fixation device, which allows for both initial graft tensioning and re-tensioning after cyclical knee range of motion. This provides the ability for the graft to accommodate for resultant soft-tissue creep and stress relaxation, thereby allowing for optimal soft-tissue tension and reduction in laxity at the end of the procedure.
