“…9 Capo et al performed ultrasonographic evaluation on 10 fresh-frozen cadaveric knees with a 14 MHz linear transducer: ultrasonographic examination did not always correctly locate the origin and insertion of the ALL, and the ALL was often difficult to isolate from the surrounding structures, even at dissection. 10 In this study, the major imaging difficulty was to correctly identify and asses the proximal portion of the ALL; however, the distal portion was reliably identified with US on each cadaver in a similar location, and could be effectively isolated during dissection.…”

Rotational stability of the knee involves not only the cruciate ligaments but also another structure named anterolateral ligament (ALL), the function of which is still controversial. This study evaluated the effectiveness of high-resolution ultrasound (US) examination to detect the ALL. We studied 8 cadaveric knees (8 ALLs). On each knee, high-resolution real-time ultrasonography examination was performed by an experienced musculoskeletal radiologist before and after the procedure, with the surgeons blind to the results of the scan both before and after dissection. The ALL was identified in each cadaver limb by the musculoskeletal radiologist. US is a useful imaging modality to identify and evaluate the ALL. The ability of US to fully evaluate injuries involving the ALL still needs to be demonstrated in a clinical setting.

“…In this context, it is important to highlight that all these investigations used (in whole or in part) samples from fresh cadavers 10 , 14 - 16 or studied living individuals through images such as magnetic resonance 15 17 , 18 However, there is no consensus among the results of these studies on the anatomical characteristics of the ALL: 10 , 16 , 19 , 20 while some studies verified the presence of the ALL in most of the samples, 10 , 15 , 16 others did not identify this ligament in even half of the specimens, 21 , 22 and one study show no ALL in their samples 19 . Furthermore, contradictory results exist within the same investigation: Vincent et al 9 identified the ALL of the knee as a capsular structure in individuals during arthroscopic knee surgery, while in its cadaver sample this ligament was found to be intracapsular.…”

Study of the Anterolateral Ligament of the Knee in Formalin-Embedded Cadavers

Objective: To verify the incidence and characterize morphologically the anterolateral ligament of the knee (ALL) in cadaveric samples of the collection of the Laboratory of Anatomy of the Department of Morphology of the Universidade Federal do Espírito Santo. Methods: Dissections and cross sections were performed for mesoscopic analysis of the anterolateral region of 15 knees preserved in 4% formalin solution in order to identify the ALL. Results: After dissection of the skin and subcutaneous tissue of the knee anterolateral region, it was possible to identify the iliotibial tract (ITT), the patellar ligament and the femoral biceps tendon. The ITT was removed from the Gerdy tubercle and the following structures were visualized: knee joint capsule, fibular collateral ligament and popliteal tendon. However, the ALL was not identified in any of the samples. Conclusions: The ALL could not be identified in any of the specimens studied, either through dissection or mesoscopic analysis. Level of Evidence III, Diagnosis Studies - Investigation of an Exam for Diagnosis.

“…La fractura de Segond se puede justificar como una avulsión de este ligamento en su inserción tibial (9,27,28) . La resonancia magnética (RM) (8,(28)(29)(30) y la ecografía (31)(32)(33) están siendo utilizadas para caracterizar este ligamento.Para su tratamiento se dispone de diversas técnicas de refuerzo extraarticular con diferentes tipos de injerto (34)(35)(36)(37) , obteniendo buenos resultados tras un seguimiento de 24 meses (38) . Debido a la gran cantidad de estudios con respecto a este ligamento en los últimos años, se cree conveniente realizar esta revisión bibliográ-fica para definir la incidencia, la anatomía, la biomecánica, la clínica, las pruebas de imagen y el tratamiento del mismo.…”
