Where does the MCL connect?

• A. Lateral Femoral Condyle to Upper Tibia
• B. Medial Femoral Condyle to Upper Tibia
• C. Medial Femoral Condyle to Lower Tibia
• D. Lateral Femoral Condyle to Lower Tibia

Answer: (B)

The medial collateral ligament slows inward collapse of the knee by connecting the inner side of the knee from the medial femoral condyle to the proximal (upper) part of the tibia. This placement—medial femoral condyle to upper tibia—lets it brace against valgus stress and stabilize the knee at the joint line. The other options would place the attachment on the outside of the knee or lower down on the tibia, which doesn’t match the true anatomy of the MCL.
