Thanks to the arthroscopic revolution, the number of meniscectomies continued to dramatically increase until the 2010s. However, a better understanding of the role of the menisci, improvements in meniscus repair techniques, and the precise assessment of outcomes have allowed us to completely modify the management of meniscus tears or lesions. Meniscectomy is no longer the first-line treatment. There is a complete paradigm shift. Meniscus preservation (which means meniscus repair or let the meniscus alone) is currently the first-line treatment, regardless of the type of meniscus tear and the etiology (traumatic or degenerative). The number of meniscectomies has decreased. However, there are still indications, which have been well described by the two ESSKA consensus, one devoted to traumatic tears and the other to degenerative lesions. The terminology of meniscus damage was also defined during the consensus projects. An acute injury of the meniscus caused by an adequate trauma is defined as a tear, and a chronic damage to the meniscus caused by microtrauma over time, lacking an adequate trauma, is defined as a lesion. Thus, a degenerative meniscus injury should be named a lesion.
