The meniscus was once considered a functionless remnant of muscle1 that should be removed in its entirety at any sign of abnormality2. Its role in load distribution3, knee stability4, and arthritis prevention5 has since been well established. The medial and lateral menisci are now considered vital structures in the healthy knee6,7. Advancements in surgical techniques and biologic augmentation methods have expanded the indications for meniscal repair, with documented healing in tears previously deemed unsalvageable8-11. In this article, we review the anatomy and function of the meniscus, evaluate the implications of meniscectomy, and assess the techniques of, and outcomes following, meniscal repair.
