Puzzitiello RN, et al. - Researchers systematically reviewed the literature to assess the reliability, or the ability of a repeated measurement to yield consistent results, and validity of ultrasound (US) and magnetic resonance imaging (MRI) at evaluating anatomy and pathology of the anterolateral ligament of the knee (ALL) in the setting of anterior cruciate ligament (ACL) injuries. They also reviewed the incidence and correlation of ALL injury with the pivot-shift examination and other structural injuries for additional clinical relevance. On MRI or US, concomitant ALL injuries can be identified with high levels of inter- and intraobserver reliability in patients with ACL injuries. They noted an association of these injuries with a high-grade pivot-shift examination, lateral collateral ligament injury, and lateral femoral condyle and tibial plateau bone bruises.
