A New Entity of Ramp Lesion Combined with Posterior Root Tear of the Medial Meniscus: A Case Report

JBJS Case Connect. 2024 May 3;14(2):e23.00439. doi: 10.2106/JBJS.CC.23.00439. eCollection 2024 Apr 1.

Abstract

Case: This report describes a new pattern of meniscal tear in an 18-year-old man after a knee sprain; he had undergone anterior cruciate ligament revision (ACL-R) 3 years earlier. He was diagnosed with an anterior cruciate ligament (ACL) graft rupture, a ramp lesion (Thaunat type 4), and a posterior root avulsion fracture of the medial meniscus (MM) (LaPrade type 5). He was treated successfully with an all-inside repair of the ramp lesion, a transtibial pull-out repair of the root tear, and ACL graft revision and anterolateral stabilization.

Conclusion: This specific meniscal injury pattern should be recognized and documented, potentially warranting consideration as a new addition to Thaunat and LaPrade classifications as type 6.
