Abstract

Medial meniscal root tears with extrusion result in the loss of transmission of circumferential hoop stresses, leading to significantly increased tibiofemoral contact pressure and changes in knee biomechanics and kinematics. Therefore, medial meniscal root tears have attracted attention in recent years with regard to their early diagnosis. With the remarkable development of magnetic resonance imaging and arthroscopy, early diagnosis of medial meniscal root tears is on the rise. This report includes diagnosis and current trends of medial meniscal root tears.
