Which statement best describes the load-distribution role of the menisci?

• A. They prevent any movement
• B. They attach to ACL
• C. produce synovial fluid
• D. It provides shock absorption and lubrication to the knee

Answer: (D)

The load distribution role of the menisci is to spread axial forces across the knee joint and cushion impact during weight-bearing. Their wedge-shaped fibrocartilage fills the space between the femoral condyles and the tibial plateau, increasing joint congruity and distributing contact stresses over a larger area, which lowers peak stress on the articular cartilage. This also supports lubrication by helping maintain a smooth, congruent joint surface that allows even distribution of synovial fluid during movement. They don’t prevent movement entirely, aren’t attached to the ACL, and synovial fluid is produced by the synovial membrane, not the menisci.
