MRI Evaluation of Anterolateral Ligament of the Knee: A Cross-Sectional Study in Malaysia

Introduction After detailed anatomical delineation of the anterolateral ligament (ALL) knee, there is a surge in research on this structure. Owing to variation and lack experience identification structure, magnetic resonance (MR) evaluation ALL produces mixed results. It was aimed evaluate using routinely performed MR imaging knee determine any associated factors with injuries. Materials methods Thirty-six images from 31 patients January 1, 2017, June 30, are evaluated. sequences include T1-weighted, T2-weighted, proton density (PD), PD fat saturation (FS). All were double-read by two authors approved consultant radiologist more than 20 years radiological experience. The divided into three portions: femoral, meniscal, tibial, considered fully visualized when all portions seen images. Results At least portion 27 scans (75%), it (55.6%). femoral most commonly identified followed meniscal (69.4%) tibial (58.3%). ALLs best coronal view FS lateral inferior genicular artery as guide locate bifurcation components. Conclusion can be routine 1.5-T imaging, either full (55.6%) or partially (75%). characterized via PD-weighted sequence plane. injury an anterior cruciate (ACL) injury.
