The peripheral attachment of the medial meniscus connects its outer margin to the deep MCL (coronary ligament), limiting medial meniscal mobility to approximately 5mm of AP movement.
Anchors the medial meniscal periphery and limits mobility — the basis of the RAMP lesion in ACL-concurrent injuries.
RAMP lesions (posterior peripheral medial meniscal detachment) occur in 9-17% of ACL tears. Identified by posterior interval probing and repaired through a posteromedial portal.
