Anatomy · Lower limb: fibular collateral ligament

Sample item

A basketball player takes a blow to the inner knee while the foot is planted and the knee is extended. The joint gaps on the lateral side with varus stress. Which ligament is torn?

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

The answer and the reasoning

B. Fibular collateral ligament

The fibular (lateral) collateral ligament runs from the lateral femoral epicondyle to the fibular head. It resists varus stress, is extracapsular and is not attached to the lateral meniscus. The tibial collateral ligament resists valgus stress.

Option by option

  • A. Anterior cruciate ligament

    The anterior cruciate ligament resists anterior tibial translation.

  • B. Fibular collateral ligament (correct)

    Correct. The fibular collateral ligament resists varus stress at the lateral joint line.

  • C. Tibial collateral ligament

    The tibial collateral ligament resists valgus stress on the medial side.

  • D. Posterior cruciate ligament

    The posterior cruciate ligament resists posterior tibial translation.
