Which knee ligament is located on the medial side of the knee?

• A. Medial Collateral Ligament
• B. Anterior Cruciate Ligament
• C. Lateral Collateral Ligament
• D. Posterior Cruciate Ligament

Answer: (A)

This question targets knee ligament anatomy and the specific location of a ligament on the inner side of the knee. The structure on the medial side is the medial collateral ligament, running from the medial femoral epicondyle to the medial tibial condyle. It resists valgus stress—forces that push the knee inward—and helps stabilize the knee against inward collapse. The other ligaments are located elsewhere or inside the joint: the lateral collateral ligament is on the outer side, and the anterior and posterior cruciate ligaments cross inside the knee. Because the ligament on the medial side is the medial collateral ligament, that is the correct choice.
