A meniscus is a piece of cartilage (rubbery tissue) that acts as a
shock absorber between bones and stabilizes the joints by evenly distributing
the load across the joint area. Menisci (plural of meniscus) protect and
cushion the joint surface and bone ends.
In the knee, the crescent-shaped menisci are positioned between
the ends of the upper (femur) and lower (tibia) leg bones. The menisci protect
the knee joint surface. And they absorb the shock produced by activities such as
walking, running, and jumping.
