Which meniscus is more frequently injured?

• A. Lateral meniscus
• B. Medial meniscus
• C. Both equally
• D. Neither meniscus

Answer: (B)

The medial meniscus is more frequently injured than the lateral meniscus due to its anatomical characteristics and the mechanics of the knee. The medial meniscus is more firmly attached to the tibia and the medial collateral ligament, which makes it less mobile compared to the lateral meniscus. This limited mobility means that it’s more susceptible to injuries, especially during activities that involve twisting or sudden changes in direction, which can place stress on the knee. Moreover, the medial meniscus is more often involved in knee injuries such as tears occurring with ligament injuries, particularly the anterior cruciate ligament (ACL) tear. This association occurs because the medial meniscus acts as a cushion and stabilizer of the knee joint during motion, and any traumatic force that affects the stability of the knee can lead to a medial meniscal tear. In contrast, the lateral meniscus is more mobile and less directly affected by the stresses resulting from common knee injuries. Consequently, while both menisci are important to the function of the knee, the conditions surrounding knee injuries often lead to a higher rate of medial meniscus injuries.
