Which anatomical structure is assessed using the Lochman's test?

The Lochman's test is specifically designed to assess the integrity of the anterior cruciate ligament (ACL). This test is particularly effective because it isolates the ACL from other structures in the knee, allowing the examiner to evaluate its stability. During the test, the patient is positioned supine, and the examiner stabilizes the femur with one hand while using the other hand to pull the tibia forward. An excessive anterior movement of the tibia in comparison to the femur can indicate ACL injury or tear.

Understanding the relevance of the ACL in knee stability is crucial, as it plays a key role in controlling knee motion, particularly during activities that involve sudden stops or changes in direction. Detection of ACL injuries is vital in managing knee-related issues, and the Lochman's test is a commonly taught technique in physical assessments for this purpose.
