Magnetic Resonance Image Characterization of Knee Meniscus Signal Intensity using Crue’s Approach: Results from a Multi-centre Evidence

Abstract

This study aimed to characterize knee meniscus signal-intensity using magnetic resonance imaging. Our research included knee MR images of 138 subjects from multi-centres in Nigeria, between September 2016 and December 2017. Knee images were retrieved from patients' folder of MRI scanners and transfered to a DICOM workstation (Onis 2.6) for image analysis. Knee meniscus was characterized into 0, 1, 2 & 3 grades using Crue’s grading approach. Our research revealed 58% incidence of meniscal lesion. Study yielded a significant relationship between meniscal lesion and gender (p <.005) with a greater proportion of these lesions in women than in men. Meniscal lesions showed significant association with osteoarthritis (OA) (p < 0.05). Grade 3 lesions (actual tears) were largely of horizontal configuration.
