Medial Meniscal Peripheral Attachment

insertio peripherica menisci medialis

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.

Region: Knee
Biomechanics

Function & Actions

Anchors the medial meniscal periphery and limits mobility — the basis of the RAMP lesion in ACL-concurrent injuries.

Clinical Relevance

Clinical Notes

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.
