1. Shock Absorption: They act as cushions between the femur (thighbone) and tibia (shinbone), absorbing the impact of weight-bearing activities and protecting the joint from wear and tear.
2. Joint Stability: The menisci help to stabilize the knee joint by distributing weight evenly across the articular surfaces and limiting excessive movement.
3. Lubrication: They contribute to the smooth movement of the knee joint by providing a smooth, low-friction surface for the bones to glide over.
4. Nutrient Supply: They play a role in nourishing the articular cartilage.
5. Proprioception: They provide sensory information about the position and movement of the knee joint.
In summary, the menisci are essential for the proper function of the knee joint, providing shock absorption, stability, lubrication, nutrient supply, and proprioception.
