Anatomy of the meniscus
** Thanks to Dr. S.P. Arnocsky Click here to see a plastic model |
This image clearly shows a triangular section of the meniscus. It can be easily seen that the blood supply to the meniscus comes from the periphery of the meniscus, which is closely related to the capsule of the knee, at the center. The black fibers - on the left in this image - are micro blood vessels which can’t reach the most central part of the meniscus (point of the triangle). This is the reason why a meniscal injury (when it is not peripheral) can have difficulty in healing spontaneously. Click here to see the shape (half-moon) of the meniscus...
