[Classification and treatment of modern traumatic meniscal tears]

The menisci have several important biomechanical functions. Traumatic meniscal injuries present a wide spectrum of presentation and several types of lesions. They can concern the body of the meniscus and its fixation. An easy and clear classification of traumatic meniscus tears is essential for helping the physicians to achieve the correct surgical indication and the accurate postoperative rehabilitation protocol. The aim of this current concept review is to clearly describe some classical as well new type of meniscal and menisco-synovial lesions such as ramp lesions, root tears and instability of the lateral meniscus associated to rotational laxity. The goal is to focus on the definition, diagnosis, classification, giving some guidelines and discussing the different rehabilitation protocols.
