What is the function of the semilunar cartilages?

The semilunar cartilages, also known as the menisci, are C-shaped fibrocartilaginous structures located in the knee joint. Their primary function is to act as shock absorbers, helping to distribute weight and reduce friction between the femur and tibia during movement. They also contribute to joint stability and improve the fit between the articulating bones, enhancing overall knee function.
