To illustrate the discrepancies between knee MRI reports and arthroscopy findings of posterior horn medial meniscal and meniscocapsular tears (ramp lesions) in children and adolescents. We retrospectively reviewed the available data from 912 patients between January 2018 and October 2022 from multidisciplinary monthly arthroscopic-MR correlation conferences, where we discussed discrepant findings between MRI knee reports and intra-operative arthroscopy findings, with focus on presence, location and type of posterior horn medial meniscal and posterior meniscocapsular tears. Results of secondary reviews of the MRI scans regarding under or over called diagnoses based on an arthroscopic reference standard were also available.
By sharing our experience and the lessons we have learned from these multidisciplinary conferences, we highlight the challenges that radiologists might face while diagnosing pediatric meniscal tears on MRI. Read More

Mensicocapsular injury (ramp lesion) occurs in 9-17% of ACL tears. These injuries are a risk factor for instability and failure following ACL reconstruction. The far peripheral location has contributed to under-diagnosis during routine anterior-approach arthroscopy. While there has been increasing interest in the identification and treatment of these lesions in adults, there is a paucity of published data on children and the proposed MRI features lack specificity. Therefore, the purpose of this study was to investigate the performance of MRI criteria for identifying ramp lesions in children. Read More
