The meniscus is a C-shaped cartilage disk that is found in the knee. The majority of these types of tears do not need surgery. The lateral meniscus has a symmetrical C-shape, whereas the medial meniscus is more crescentic (3a), as the posterior horn of the medial meniscus is always larger than the anterior horn. These can occur through either a contact or non-contact injury for example, a pivoting or cutting injury. If you have a meniscus tear, this movement may cause pain, clicking, or a clunking sensation within the joint. and oblique tear . These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses.

We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. It has been shown the peak tibiofemoral contact pressure after a total meniscectomy is equal to a posterior medial meniscal root tear. Because of their importance and the clinical impact of meniscal tears, assessment of the menisci has become the most common indication for MR of the knee. Figure 1.

There are numerous treatments for meniscus tears, but treatment generally begins conservatively depending on the location, type, and size of the tear. However, whether they will respond well to surgery depends on the type of tear, the location, and blood flow in the area where the tear occurred. Chronic tears may be scarred to the capsule and require release of the meniscocapsular junction to allow anatomic repair. Meniscus Tears - OrthoInfo - AAOS - American Academy of Orthopaedic It absorbs about 50% of the shock of the medial compartment.
