What would indicate a positive McMurray's test?

A positive McMurray's test is indicated by the presence of a sound or click during knee extension or flexion. This test is specifically designed to assess for meniscal tears in the knee. When a clinician performs the McMurray's test, they manipulate the knee in specific ways while feeling for any abnormal movement or sound, which suggests the presence of a tear in the meniscus. Hearing a click or pop during this manipulation can indicate that a torn meniscus is getting caught in the joint space, which is a classic indicator of this injury.

The other options do not signify a positive McMurray's test. Increased range of motion typically does not indicate any pathology and would not be a sign of a meniscal tear. Severe bilateral pain could occur from various knee issues but does not specifically relate to the McMurray's test or suggest a meniscal tear. The positive anterior drawer sign assesses the integrity of the anterior cruciate ligament (ACL) and does not provide information about the meniscus, making it unrelated to the specifics of the McMurray's test result.
