What description fits the medial meniscus?

The medial meniscus is best described as C-shaped and is known to have a specific anatomical relationship with the medial collateral ligament (MCL). This unique shape provides stability to the knee joint, as the medial meniscus plays a crucial role in weight distribution across the knee and in absorbing shock during movement. The attachment to the MCL provides an additional layer of support, as both structures work together in the function and stability of the knee.

The C-shape is characteristic of the medial meniscus, making it distinct from the lateral meniscus, which is more circular in shape. This anatomical configuration helps facilitate movement during flexion and extension of the knee. Additionally, since the medial meniscus is less mobile compared to the lateral meniscus, it is more prone to injuries.

In contrast to the other options, the description of shape and attachment to the MCL is crucial in understanding the function of the medial meniscus in relation to the knee's overall biomechanics.
