Meniscus is a crescent-shaped structure medially and laterally located between femur condyles, and tibia. Both menisci are `C` shaped; the lateral meniscus has a more circular appearance than the medial meniscus; the distance between the anterior and posterior horns is rather short. The medial meniscus is reverse U-shaped, and the distance between the anterior and posterior horns is longer. The incidence of meniscus tears is 60–70 in 100,000. Diagnosed isolated tears are 3 times more likely to be lateral rather than medial. Story and clinical examination can diagnose about 70% like many other orthopedic diseases. Magnetic resonance imaging is one of the most commonly used methods for diagnosing meniscal tears but radiography, contrast-enhanced computed tomography, and arthrography are also used in the diagnosis. We will discuss imaging methods and activities that can be used to diagnose meniscus lesions.
