Describe the McMurray's test protocol.

• A. The knee is fully flexed then extended while tibia is internally and externally rotated and joint line palpated.
• B. The knee is extended and flexed repeatedly with no rotation.
• C. The knee is rotated while applying circumferential palpation.
• D. The knee is flexed and held without rotation.

Answer: (A)

The test targets meniscal tears by using a maneuver that combines knee flexion, tibial rotation, and controlled extension while feeling along the joint line for a click or pain. Start with the knee bent, then move into extension while rotating the tibia: externally rotate to stress the lateral meniscus and internally rotate to stress the medial meniscus, all while palpating the joint line for a reproducible click or pain. This sequence is what makes the McMurray test able to reveal a tear. The other descriptions don’t fit because they omit either the rotation component needed to bias the menisci, or the movement through extension with palpation, which is essential to elicit the characteristic sign.
