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

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

Answer: (B)

Structure B is the lateral epicondyle. This is the outer-side bump on the distal femur, located just above the lateral condyle, and it serves as an attachment site for ligaments and soft tissues around the knee. The other knee landmarks described—lateral plateau (the top surface of the tibia that articulates with the femur) and the femoral condyles themselves (lateral and medial)—are located in different positions or represent articular surfaces, not the non-articular projection above the condyle. So the labeled structure corresponds to the lateral epicondyle.
