Fibrocartilage

In the knee, the menisci form an interarticular fibrocartilage base for femural and tibial articulation. The menisci form a crescent shape in the knee. The lateral meniscus is located on the outer side of the knee, and the medial meniscus is located on the inside of the knee. If the knee bends and twists the menisci can overstretch and tear. Menisci tears occur frequentiy and the knee can sustain more than one tear at a time. If not treated appropriately, however, a menisci tear can roughen the cartilage and lead to arthritis. A meniscus tear acts like grit in the ball bearings of a machine. The longer the torn tissue remains affected, the more irritation it causes.

Meniscus A C-shaped fibrocartilage anatomically located between the femoral condyles and tibial plateau providing stability and shock absorption and assisting in lubrication of the knee joint. 

Another possibility is the application of mesenchymal precursor cells (MFCs) loaded in hydrogel with soluble factor as pentosan polysulphate [34], Frith et al showed evidence that this system has significant potential as both a delivery vehicle for MFCs and as a matrix for fibrocartilage tissue engineering applications.

The ACL insertion sites were easily discemable by distribution of the calcified fibrocartilage having smooth surface. In the femoral insertion, the AM-L bundle occupies the proximo-anterior part, and the AM-M btmdle occupies the proximo-posterior part. The PL bundle occupies the distal part. In the tibial insertion, the AM-M bundle occupies the anteromedial part, and the AM-L bundle occupies the anterolateral part. The PL bundle occupies the posterior part.
