Which test would be the most effective for assessing a suspected medial meniscus tear?

• A. Apley compression test
• B. Pivot shift test
• C. McMurray test
• D. Lachman test

Answer: (C)

The McMurray test is particularly effective for assessing a suspected medial meniscus tear because it specifically evaluates the integrity of the menisci during knee flexion and extension. During the test, the clinician manipulates the knee by externally or internally rotating the tibia while applying a valgus or varus force. In a case of a medial meniscus tear, pain or a "click" sensation may be felt as the torn meniscus moves in and out of the joint during this maneuver. This test has been well-studied and is known for its ability to elicit symptoms directly related to the condition being assessed. It serves not only to identify a medial meniscus tear but also to help differentiate between various knee pathologies based on the specific position and force applied during the test. While other tests like the Apley compression test and the Pivot shift test also have their roles in assessing knee injuries, the McMurray test's specific mechanics and ability to reproduce symptoms of a medial meniscus tear make it the most effective choice in this context. The Lachman test, on the other hand, is focused primarily on assessing the stability of the anterior cruciate ligament and is not suited for evaluating meniscal injuries.
