Evaluation of meniscal degeneration in asymptomatic subjects and patients with early osteoarthritis (KL = 1,2) was performed using adiabatic $$T_{1\rho}$$$and $$T_{2\rho}$$$ ($$AdT_{1\rho}$$$and $$AdT_{2\rho}$$$, respectively) measurements in sagittal plane. Menisci of all subjects were also evaluated using semiquantitative MRI OA Knee Score (MOAKS). The results show that the length of $$AdT_{1\rho}$$$and $$AdT_{2\rho}$$$ is directly related to clinical symptoms and the severity of meniscal degeneration. $$AdT_{1\rho}$$$and $$AdT_{2\rho}$$$ may provide a non-invasive means of detecting and monitoring degenerative changes in the meniscus.
