What is the function of the meniscus in the knee?

The meniscus in the knee serves two primary functions: providing cushioning and enhancing stability. It is made of cartilage, which acts as a shock absorber between the femur (thigh bone) and the tibia (shin bone), helping to reduce the impact during activities such as walking, running, and jumping. This cushioning protects the bones from excessive wear and tear. Additionally, the meniscus contributes to the overall stability of the knee joint by ensuring even distribution of weight across the joint surfaces and aiding with joint congruity. This is especially important during movements that involve pivoting or changes in direction, as it helps to prevent injury to the ligaments surrounding the knee.
