McMurray’s test is used to evaluate for meniscal pathology. To perform this test, have the patient lying supine and relaxing her legs. With one hand, grasp the patient’s heel and with the other hand, grasp the patient’s knee, being sure to palpate the joint line of the knee with your thumb laterally and your index finger medially. To evaluate the medial meniscus, move the patient’s hip and knee in to flexion, then externally rotate and extend the knee. To evaluate the lateral meniscus, move the patient’s hip and knee into flexion, then internally rotate and extend the knee. The test is positive if a painful click is heard or felt, or if the knee locks during this maneuver.
