In the knee anatomy, Structure D corresponds to which structure?

• A. Medial condyle
• B. Lateral epicondyle
• C. Lateral condyle
• D. Tibial plateau

Answer: (C)

At the knee, the main articulating surfaces on the distal end of the femur are the two condyles—medial and lateral—that sit atop the tibial plateau and form the hinge-like joint with the tibia. If Structure D is the rounded articular surface on the outer side of the distal femur, it is the lateral condyle. The tibial plateau lies on the top of the tibia and serves as the contact surface for these condyles, not on the femur itself. The lateral epicondyle is a non-articular projection above the condyle, and the medial condyle would be the inner counterpart. So Structure D matches the lateral condyle.
