Which meniscus is described as O-shaped and more mobile?

The lateral meniscus is characterized by its O-shape and greater mobility compared to the medial meniscus. This anatomical design allows the lateral meniscus to move more freely within the knee joint during various movements, such as flexion and extension. Its increased mobility is crucial for the function of the knee, as it aids in shock absorption and weight distribution during activities like running and jumping. Additionally, the distinct shape of the lateral meniscus contributes to its ability to adapt and accommodate the dynamic movements of the knee joint, which is essential for maintaining optimal biomechanics and reducing the risk of injury.
