Ramp lesions, often seen in ACL reconstruction cases, involve the posterior horn of the medial meniscus and its attachments, notably the meniscocapsular junction and meniscotibial ligament (Ahn et al., 2011; Dephilippo et al.2018). While some suggest that these lesions might heal well, their impact on cartilage biomechanics remains uncertain, with limited literature addressing joint kinematics and loading in the medial compartment. Consequently, this study aims to bridge this gap by measuring medial tibial strain variations coupling 7T-Magnetic Resonance Imaging (MRI) and the DVC method in three conditions.http://mbj.episciences.org/14539/pdfMRIDigital volume correlation (DVC)CartilageRamp lesionMedial meniscus[PHYS.MECA.BIOM]Physics [physics]/Mechanics [physics]/Biomechanics [physics.med-ph]
