Editorial commentary: Medial meniscal ramp lesions: Lessons learned from the past in the pursuit of evidence.
- Sports Medicine Research Laboratory
Thirty-five years after their initial description, ramp lesions of the medial meniscus in anterior cruciate ligament (ACL)-deficient knees are slowly being rediscovered. Routinely repaired in open ACL and peripheral reconstructions before the era of arthroscopic ACL reconstruction, ramp lesions have been largely ignored in the last 2 decades. Following the growing number of studies analyzing the causes of residual laxity after ACL reconstructions over the last decade, ramp lesions are increasingly being implicated, and thus investigated, but remain poorly understood. They are difficult to diagnose, both clinically and with magnetic resonance imaging. Future efforts are needed to close the knowledge gaps on their etiology, biomechanical impact, diagnosis, and repair.
