The menisci are two semicircular discs of elastic consistency located between the tibia and femur within the knee joint. Their main functions include load distribution and shock absorption, reducing impact on the femoral and tibial cartilage. They also contribute to joint stability along with ligaments. Meniscal injuries can result from a sprain or trauma to the knee leading to rupture, usually in younger people, or can happen due to repetitive and chronic impact on the joint.
