Degeneration: Mri scans image tissue by measuring hydrogen atoms such as are found in water (h2o - 2 parts hydrogen, 1 part water) . As a meniscus ages the tissue degenerates and is replaced by fluid which is mostly water. Increased MRI signal ( increased fluid) usually means some degeneration of the meniscus which is a consequence of aging.
