What is the function of the meniscus in the knee?

The meniscus plays a crucial role in the knee joint's overall function by providing both cushioning and stability. It is a C-shaped cartilage structure located between the femur (thigh bone) and the tibia (shin bone). Its primary function is to absorb shock during weight-bearing activities, such as walking or running, minimizing impact on the bones and surrounding tissues. Additionally, the meniscus helps distribute body weight evenly across the knee joint, which enhances stability and reduces the risk of injury.

The ability of the meniscus to improve joint stability is particularly significant during movements that involve pivoting or changes in direction, as it helps maintain proper alignment of the femur and tibia. This is essential for optimal knee function and mobility. In contrast to the other options, the meniscus does not primarily absorb excess synovial fluid, provide joint lubrication, or serve as a direct connector between the femur and the tibia, indicating that its main functions are accurately captured as cushioning and stabilizing the knee joint.
