During internal or external rotation of the knee, which bony structures do the menisci follow?

• A. Tibial plateau
• B. Patella groove
• C. Medial collateral ligament
• D. Femoral condyles

Answer: (D)

During knee rotation, the moving partner in the joint is the femoral condyles, which roll and glide on the tibial plateaus. The menisci sit between these surfaces and are carried along by that motion to preserve contact area and joint congruence. Although the menisci are anchored to the tibia, their body tracks with the femoral condyles as the knee internally or externally rotates. The other structures listed don’t drive this tracking: the patellar groove relates to patellofemoral movement, and the medial collateral ligament is a stabilizer rather than a guide for meniscal motion.
