current concepts on posterior meniscal root lesion: a treatment algorithm based on the currently available evidence

Meniscal root lesion is defined as an avulsion of the tibial insertion of the meniscus or a radial tear close to the meniscal insertion, which is commonly observed at the posterior region in the clinical practice. Although a number of biomechanical and clinical studies have shown the importance of the integrity of the posterior meniscal roots, the appropriate treatment is still controversial. The purposes of this review are to develop a current understanding of how the posterior meniscal root functions and to review the available treatment options for posterior meniscal root lesion.
