Meniscus Repair and Replacement: New Techniques, Indications and Biologic Augmentations (AANA22)-Root & Ramp Tears

Video Transcription

Video Summary

The discussion covers meniscal root and ramp lesions, emphasizing their importance in knee biomechanics, especially in ACL injuries. Root tears disrupt hoop stresses and cause meniscal extrusion, linked to cartilage damage and alignment issues; repair involves arthroscopic suture pull-out techniques secured to bone, requiring careful rehab. Ramp lesions, frequent but often missed, occur at the meniscus-capsule junction, causing anterior tibial translation; they demand visualization through special scopes and repair to restore function. MRI sensitivity is limited, so direct arthroscopic assessment is vital. Repairing these lesions during ACL reconstruction improves outcomes and knee stability, reducing progression to arthritis and need for arthroplasty.
