Musculoskeletal Ultrasound Imaging of the Recently Described Anterolateral Ligament of the Knee

Ultrasonography imaging of the anterolateral ligament using real-time virtual sonography

“…Although a single previous case report presented an ultrasonographic description of the ALL [14], in this report, there was no confirmation that the ultrasonographic images were indeed those of the ALL.…”

Ultrasonographic assessment of the anterolateral ligament of the knee in healthy subjects

“…A 30-35° of knee flexion was used as previously suggested by Parson's biomechanical essay 7 , and recently adopted in Oshima's study 16 . Cianca et al described a different approach in the identification of the ALL using 90° flexion of the knee 14 . To better visualize the ALL, we applied a slight internal rotation of the tibia as described by Cianca in his case report 14 , and used by Cavaignac et al in their cadaveric study on 20 knees 15 .…”

In our experience, the visualization of the ALL is possible if all landmarks are recognized (Fig.…”

“…At present only three studies identify the ALL on ultrasound (US) imaging. In 2014, Cianca et al reported an ultrasonographic description of the ALL in a case report 14 ; in 2015, Cavaignac et al studied US sensitivity in the detection of the ALL in 18 cadaveric knees 15 ; lastly, in a recently published study, Oshima et al evaluated the efficacy of US in demonstrating ALL in 9 healthy subjects 16 . Therefore, the aim of this study was to determine inter-observer agreement of the ultrasonography in the identification of the ALL and in the evaluation of its length and thickness in healthy subjects.…”

Is it safe to reconstruct the knee Anterolateral Ligament with a femoral tunnel? Frequency of Lateral Collateral Ligament and Popliteus Tendon injury

“…With the growing knowledge of the ALL, this structure has been studied through the use of anatomical specimens as well as magnetic resonance imaging [11][12][13], ultrasound [14] and radiography [15,16]. Thus, it is likely that studies on its reconstruction will soon emerge.…”
