The medial meniscus can also be referred to as the inner semilunar fibrocartilage. It is one of two crescent-shaped structures in the knee joint that provide cushioning between the femur and tibia. Other synonyms for the medial meniscus include the medial cartilage disc, inner meniscus, and internal knee cartilage. The medial meniscus is a vital component of the knee joint, as it helps to absorb shock, distribute weight, and maintain stability. Injuries to the medial meniscus are common in athletes and those who participate in activities that require sudden stops, twists, or pivots. Treatment may include rest, ice, physical therapy, or in severe cases, surgical intervention.
