“…This ligament is known to be variable. [19][20][21] We are currently examining its role in controlling displacement of the anterior and radial regions of the menisci. In some patients, the anterior horn of the medial meniscus can be seen, arthroscopically and on MRI, to lie anterior to the tibial articular surface in an almost 'prolapsed' position.…”

W e present the first study in vivo of meniscal movement in normal knees under load. Using an open MR scanner, allowing imaging in physiological positions in near to real-time, 16 young footballers were scanned moving from full extension to 90°fl exion in the sagittal and coronal planes. Excursion of the meniscal horns, radial displacement and meniscal height were measured. On weight-bearing, the anterior horn of the medial meniscus moves through a mean of 7.1 mm and the posterior horn through 3.9 mm, with 3.6 mm of mediolateral radial displacement. The height of the anterior horn increases by 2.6 mm and that of the posterior horn by 2.0 mm. The anterior horn of the lateral meniscus moves 9.5 mm and the posterior horn 5.6 mm, with 3.7 mm of radial displacement. The height of the anterior horn increases by 4.0 mm, and that of the posterior horn by 2.4 mm. In non-weight-bearing, the anterior horn of the medial meniscus moves 5.4 mm and the posterior horn 3.8 mm, with 3.3 mm of radial displacement. The anterior horn of the lateral meniscus moves 6.3 mm, and the posterior horn 4.0 mm, with 3.4 mm of radial displacement. The most significant differences between weight-bearing and non-weight-bearing were the movement and vertical height of the anterior horn of the lateral meniscus.

“…Four different types of MM ligaments have been described in the medical literature. (1)(2)(3) The most commonly observed of these intermeniscal ligaments is the anterior intermeniscal ligament, with a reported frequency of 58%, followed by the posterior intermeniscal ligament, with a reported frequency of 1%-4%.…”

“…They reported that the ligament could be mistaken for an anterior cruciate ligament stump due to its proximity to the anterior cruciate ligament as it traverses the intercondylar notch. 4 Cadaveric studies have suggested increased excursion of the anterior horn of the medial meniscus at 30° of knee flexion with transection of the anterior transverse meniscal ligament, although the clinical relevance is unknown. 6,7…”

“…1,2 The oblique meniscomeniscal ligaments run from the anterior horn of 1 meniscus to the posterior horn of the opposite meniscus. [3][4][5] The ligament is named for its anterior meniscal origin and has received increased attention because it is often mistaken for a displaced bucket handle meniscus tear on magnetic resonance imaging (MRI).…”

Four normal variants of meniscomeniscal ligaments have been previously reported in the anatomy, arthroscopy, and radiology literature. The anterior and posterior transverse meniscal ligaments are the 2 most commonly observed, with a reported frequency of 58% and 1% to 4%, respectively. The last 2 variants include the medial and lateral oblique meniscomeniscal ligaments and account for a combined frequency of 1% to 4%.This article describes 2 patients with unilateral meniscomeniscal ligaments observed on magnetic resonance imaging. One patient had a unilateral lateral meniscomeniscal ligament extending from the anterior horn of the lateral meniscus to the posterior horn of the lateral meniscus and underwent conservative management. The second patient had a unilateral medial meniscomeniscal ligament with a concomitant medial meniscus tear and underwent arthroscopic intervention. The ligament was stable intraoperatively and, therefore, was not resected. Both patients had resolution of their symptoms.These 2 variants are additions to the previously described 4 normal intermeniscal ligament variants. The functions of the 2 new variants described in this article are poorly understood but are thought to involve meniscal stability. Accurate descriptions of normal variants can lead to the proper management of anomalous rare structures and prevent false imaging interpretations because these structures can closely mimic a double posterior cruciate ligament sign. Furthermore, an understanding of the various normal variants of intermeniscal ligaments can prevent unnecessary surgery that could result in further iatrogenic meniscus injury.
