A Meniscus Tear. The two most common causes of a meniscus tear are due to traumatic injury (often seen in athletes) and degenerative processes (seen in older patients who have more brittle cartilage). It is not uncommon for the meniscus tear to occur along with other damage inside the knee.
People can suffer tears of the meniscus because of trauma, sports injuries or the meniscus can tear simply because it wore out. By far, the most common location for a tear is in the back, and on the inner or medial side of the knee â that is the area we call the posterior horn of the medial meniscus.he meniscus is a âcâ-shaped cartilage disk thatâs found in the knee. We have two menisci in either knee. We have the medial meniscus on the inner side of the knee and the lateral meniscus on the outer side of the knee. The menisci serve a critical function in the knee as a shock absorber or cushion.
