Meniscus repair is recommended for tears that occur in the vascular region (red zone or red-white zone), are longer than 1 cm, involve greater than 50% of meniscal thickness, and are unstable to arthroscopic probing. A stable knee
is important for successful meniscus
repair and healing. Thus, associated ligamentous injuries must be addressed. The most commonly associated ligamentous disruption is complete tear of the ACL, which must be reconstructed to prevent recurrent meniscal tears.
