Which meniscus is more commonly torn in older individuals?

• A. Lateral
• B. None
• C. Both
• D. Medial

Answer: (D)

Medial meniscus tears are more common in older adults because aging brings degenerative changes in the knee and that meniscus is relatively fixed in place. The medial meniscus is tightly connected to the tibia and the medial collateral ligament, making it less mobile and more exposed to repetitive compressive and rotational stresses during daily activities. This combination promotes gradual tearing over time. In contrast, the lateral meniscus is more mobile and often involved in acute twisting injuries seen in younger, more athletic individuals. So, the prevalence of degenerative changes and the fixed positioning of the medial meniscus explain why it tears more often with age.
