Diagnosis of Concomitant Posterior Lateral Meniscus Root Tears in Anterior Cruciate Ligament-Related Radial Lateral Meniscal Injuries: The "2R" Lesion.

ABSTRACT: Avulsion of the posterior root of the lateral meniscus have been commonly Technical Note since they are biomechanically equivalent to complete meniscectomies. The technique we describe in this study consists of identifying a posterior root tear of the lateral meniscus after detecting a radial tear in the body segment of that same meniscus. By having such a systematic approach, we ensure that posterior root lateral meniscus tears associated with meniscal body radial tears are not missed in anterior cruciate ligament-deficient patients, enabling appropriate repair and potentially reducing the risk of instability, meniscal extrusion, and early osteoarthritis.
