What does a positive McMurray test indicate?

A positive McMurray test is indicative of a possible meniscal tear of the knee. This clinical examination evaluates the integrity of the menisci, which are crescent-shaped cartilage structures that provide cushioning and stability within the knee joint. During the test, the physician manipulates the knee while applying rotation and compression or distraction forces. A palpable or audible "click" or "pop" felt during this maneuver suggests that the meniscus may be torn or damaged.

Understanding the significance of this test is crucial for accurate diagnosis and subsequent management of knee injuries. In cases of a meniscal tear, it’s important to distinguish it from other injuries or conditions, such as ligament sprains or fractures, as the management and potential surgical interventions differ significantly.
