Andrade R, et al. - With the aim to assess the normal and injured magnetic resonance imaging appearance of the anterolateral ligament (ALL), researchers performed a systematic review using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines identifying 270 original records. Of these, they included a total of 24 studies comprising 2,427 knees in 2,388 patients (mean age, 33.3 years; 66% male patients; 63% with anterior cruciate ligament [ACL] injury). The identification of normal and injured ALL definition methods and the respective magnetic resonance imaging findings varied highly in this work. They observed considerable variation in reliability rates, and often the entire portion of the ligament was not seen.
