Where is the medial meniscus less mobile compared to the lateral meniscus?

• A. In the posterior segment
• B. Along the femur surface
• C. Throughout its length
• D. Near the joint capsule

Answer: (C)

The medial meniscus is less mobile throughout its length compared to the lateral meniscus due to its anatomical attachments and structural characteristics. Specifically, the medial meniscus is more firmly attached to the tibial plateau and the joint capsule, which limits its mobility. This reduced mobility is significant because it helps maintain stability within the knee joint, particularly during weight-bearing activities. In contrast, the lateral meniscus is more freely moving and can accommodate changes in joint motion more effectively. This mobility is crucial for providing adequate cushioning and shock absorption during dynamic activities. The design and attachments of the menisci play a vital role in their function, where the medial meniscus supports stability, and the lateral meniscus offers more adaptability to movement.
