Sample item

Which ligament primarily prevents anterior translation of the tibia relative to the femur?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Anterior cruciate ligament

The anterior cruciate ligament resists anterior tibial translation and rotational instability; rupture commonly occurs with pivoting injury and may produce a positive Lachman test.

Option by option

  • A. Anterior cruciate ligament (correct)

    Correct: ACL restrains anterior movement of the tibia.

  • B. Medial collateral ligament

    MCL resists valgus stress at the knee.

  • C. Posterior cruciate ligament

    PCL mainly resists posterior tibial translation.

  • D. Patellar ligament

    Patellar ligament transmits quadriceps force to extend the knee.
