The special test most likely to detect an injury of the anterior bundle of the anterior cruciate ligament is the ______________.

• A. Pivot Shift Test
• B. Lachman Test
• C. Anteroposterior Drawer Test
• D. Anterior Drawer Test

Answer: (D)

The Anterior Drawer Test is particularly effective for assessing the integrity of the anterior cruciate ligament (ACL), especially the anterior bundle. This test specifically evaluates the anterior translation of the tibia relative to the femur when the knee is flexed at approximately 90 degrees. A positive test indicates excess anterior movement, suggesting a potential injury to the ACL. The anterior bundle of the ACL is critical for preventing anterior tibial translation and providing rotational stability to the knee. Since the Anterior Drawer Test directly examines this aspect, it is the most relevant clinical test for identifying injuries to this particular facet of the ligament. The Pivot Shift Test is primarily used to assess the overall stability of the knee and is more indicative of rotational instability often associated with both bundles of the ACL. The Lachman Test also evaluates the ACL but is typically used to assess both the anterior and posterior bundles rather than isolating the anterior bundle. The Anteroposterior Drawer Test, though similar in assessing translation, is typically less sensitive than the Anterior Drawer Test in detecting subtle injuries to the anterior bundle specifically.
