The purpose of this study was to investigate the relationship between T1rho measurements in cartilage and meniscus using quantitative MRI. Our study involving 64 subjects (including both healthy subjects and patients with osteoarthritis) found that 48% of the subjects had a meniscal tear, with the incidence being highest in the posterior medial horn. Despite these findings, we did not find a significant correlation between the T1rho cartilage and the posterior medial horn of the meniscus. However, significant correlations were found between the T1rho of the lateral meniscus and the cartilage sub compartments.
