Where does the LCL connect?

• A. Medial femoral condyle to head of fibula
• B. Lateral femoral condyle to head of fibula
• C. Lateral femoral condyle to tibial plateau
• D. Medial femoral condyle to tibial plateau

Answer: (B)

The LCL runs on the outer side of the knee from the lateral femoral condyle to the head of the fibula, anchoring the lateral aspect of the joint. This placement means it resists varus stress and external rotation of the tibia relative to the femur, especially when the knee is extended. Since it attaches to the fibular head rather than the tibial plateau, and originates from the lateral (not medial) femoral structure, the correct description is lateral femoral condyle to the head of the fibula. The other options place attachments on the wrong structures (medial condyle or tibial plateau) and do not reflect the LCL’s actual anatomy.
