The menisci are two large cartilages located on the top of the tibia in the knee, helping to protect the joint from the stresses of walking, running, and climbing. Meniscal tears are very common and are caused by trauma caused by twisting or excessive bending of the knee joint. MRI imaging of meniscal injuries is a useful tool in determining the extent of the damage and guiding appropriate treatment.

Discoid meniscus is a common abnormal meniscal variant in children. A detailed history of painful joint symptoms and physical examination combined with knee MRI help diagnose discoid meniscus more effectively in cases with a wide range of clinical presentations, from asymptomatic to severe knee pain and swelling.
