What is the role of the menisci in the knee?

• A. To connect muscles to bones
• B. To produce synovial fluid
• C. To act as shock absorbers and stabilize the joint
• D. To provide strength to the ligaments

Answer: (C)

The menisci serve a crucial function in the knee joint by acting as shock absorbers and providing stability. These crescent-shaped cartilage structures are located between the femur (thigh bone) and the tibia (shin bone). As shock absorbers, the menisci help to distribute weight and reduce the impact sustained during activities such as walking, running, and jumping, thus protecting the articular cartilage from damage. This function is vital in maintaining the health of the knee joint, as excessive stress and impact can lead to injuries and degenerative conditions. In terms of stabilization, the menisci contribute to the overall integrity of the knee by deepening the socket of the tibia, which allows for better fitting and congruence with the femur. This anatomical feature aids in guiding the motion of the knee, ensuring that the bones remain properly aligned during movement, which is essential for proper function and injury prevention. Other choices relate to different knee structure functions but do not accurately describe the specific role of the menisci.
