ANATOMY: A thorough knowledge of the anatomy and function of the knee joint is essential for understanding the mechanism of meniscal injuries. It is also useful for diagnostic evaluation of any type of knee injury. The knee joint is the largest articulation in the body. It is composed of the distal end of the femur and the proximal epiphysis of the tibia. The stability of the knee joint is provided by the anterior cruciate ligament (ACL), the posterior cruciate ligament (PCL), the medial and lateral collateral ligaments (MCL & LCL), the menisci, and by the surrounding capsule and muscles. These soft tissue structures are arranged in such a way as to provide minimal rotational movements while allowing for extension and flexion. The menisci are the remnants of an embryonic septum between the tibia and fibula (Ricklin, 1983). The menisci are two semilunar shaped wedges
