The answer is accurate because the fibula does not articulate with the femur in any anatomical position. The fibula is primarily a support structure for the tibia and plays a minor role in weight-bearing. Its proximal end does not form a joint with the femur; instead, the fibula's lateral aspect helps stabilize the ankle joint as it connects to the tibia at the ankle.

In contrast, the tibia is the primary bone that articulates with the femur at the knee joint. This lack of direct articulation between the fibula and femur is consistent across all individuals regardless of movement or physical condition. Therefore, the correct answer reflects the anatomical relationships accurately.
