Which test is commonly used to assess for torn meniscus?

1. Apley's grind test

2. McMurray's test

3. Childress test

4. O'Brien's test

The correct answer is: McMurray's test

The McMurray's test is specifically designed to assess for tears in the meniscus of the knee joint. This test involves the physician flexing the knee and rotating the leg while applying a varus or valgus stress. If a click or pop is felt, or if the patient experiences pain, it may indicate the presence of a meniscal tear. The distinct movements involved in the McMurray's test specifically target the meniscus, making it a reliable diagnostic tool in clinical settings. In contrast, other tests mentioned assess different conditions. Apley's grind test also evaluates meniscal tears but is less specific than the McMurray's test and often gives conflicting information. The Childress test is not commonly referenced in clinical practice for meniscal evaluation. O'Brien's test is primarily used to diagnose labral tears in the shoulder rather than issues in the knee joint. Thus, the McMurray's test's specific methodology and focus on the meniscus make it the correct choice for assessing a torn meniscus.
