Abstract:

A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which is known as the anterolateral meniscofemoral ligament (MFL). The MFL was attachedto the anatomic site of anteromedial bundle of ACL. ACL reconstruction surgery was performed using central 1/3 bonetendon bone graft.Practitioners should be aware that ACL reconstruction in lateral meniscofemoral ligament with associated ACL agenesisis a treatment option in which the preservation of MFL, as the stabilizer of anterior horn of lateral meniscus, should beconsidered during ACL reconstruction as a good treatment choice.Level of evidence: V

Anterolateral Meniscofemoral Ligament of the Lateral Meniscus

Anatomical variations of the meniscus are a common anomaly that knee surgeons frequently encounter. However, anomalies of the anterior horn of the lateral meniscus (AHLM) are extremely rare. In this report, we present a newly discovered anomaly of the AHML: an anterolateral meniscofemoral ligament is described with clinical features and radiographic and arthroscopic findings.

Failure of Anterior Cruciate Ligament Reconstruction

  The present review classifies and describes the multifactorial causes of anterior cruciate ligament (ACL) surgery failure, concentrating on preventing and resolving such situations. The article particularly focuses on those causes that require ACL revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. Although primary ACL reconstructio...

An In Vitro Robotic Assessment of the Anterolateral Ligament, Part 2: Anterolateral Ligament Reconstruction Combined With Anterior Cruciate Ligament Reconstruction.

BACKGROUND Recent biomechanical studies have demonstrated that an extra-articular lateral knee structure, most recently referred to as the anterolateral ligament (ALL), contributes to overall rotational stability of the knee. However, the effect of anatomic ALL reconstruction (ALLR) in the setting of anterior cruciate ligament (ACL) reconstruction (ACLR) has not been biomechanically investigate...

Anterior Cruciate Ligament Reconstruction with or without Bracing

Background: Rupture of anterior cruciate ligament (ACL) would cause instability and disability and if left untreated. Reconstruction is performed by different techniques including patellar bone graft, as the strongest device. Application of brace after ACL reconstructions has revealed doubtful results. Methods: One hundred ACL ruptured patients randomized into two groups were reconstructed with...

Biomechanical Evaluation of Pediatric Anterior Cruciate Ligament Reconstruction Techniques with and without the Anterolateral Ligament

BACKGROUND Two popular physeal-sparing procedures used in the management of anterior cruciate ligament (ACL) injuries in skeletally immature patients are the iliotibial band (ITB) ACL reconstruction (ACLR) and the all-epiphyseal (AE) ACLR. Although there has been concern for overconstraint of the lateral compartment of the knee with the ITB ACLR technique, rotational stability, as provided by t...
