Compact, semicircular shaped cartilage (tough elastic tissue) cushions in the inner portions of the junctions formed by the thigh bones and the shin bones: The medial menisci of the knees are located in the inner sides of the knee connecters.

The medial menisci of the knees provide outer curves for conjoining links to move on, serve to evenly load the structures during walking, and aid in disbursing fluids to the joints for lubrication of those skeletal parts.
