German: Meniscus articularis
The articular meniscus consists of fibrous cartilage and dense connective tissue whose fibers are aligned in a parallel way and divide the articular cavity into two compartments. Concerning the transversal slice, the joint body (discus articularis) appears wedge-shaped (cuneiform).
Menisci articulares are basically free from blood vessels. They are supplied with nutrients coming from the synovial fluid.
A typical example of menisci articulares are the fibrous discs in between the femur and tibial plateau, close to the knee joint.
The menisci accomplish different functions in the joint:
- they enlarge the surface of contact in between the parts of the joint
- they compensate incongruity of the surfaces
- they buffer the pressure which is applied onto the joint's surface and disseminate it
- they support the conducting of the head of the joint inside of the joint's socket
5 Clinical significance
Due to their exposed location inside of the joint, a meniscopathy occurs quite often. A typical example is a fissure of the inner meniscus inside of the knee joint.
