Degenerative change: Menisci are two (medial and lateral) c-shaped pieces of cartilagenous tissue in knee joint which act as shock absorbers. With age and wear and tear, menisci get thinner (attenuated) and undergo internal degeneration which increases signal on certain mr sequences. Menisci can also tear, in which case the internal signal has more linear appearance and extends to outer surface of meniscus.
