A system of canals in semilunar menisci.
Semilunar menisci of young calves, and infants and young children were examined with the scanning electron microscope and the light microscope. Canal-like structures were noted opening onto the surface of the menisci. After filling the joints with Indian ink, ink was noted within canal-like structures deep in the substance of the tissue. The canals may play a part in the transport of fluid within the meniscus, or may carry nutrients from the synovial fluid or the blood vessels to the avascular sections of the meniscus.
