McMurray Test

To test for meniscal Injury

Patient lies in the supine position with knee completely flexed.

The examiner then medially rotates the tibia and extends the knee. If there is a loose fragment of the lateral meniscus, this action causes a snap or click that is often accompanied by pain. By repeatedly changing the amount of flexion and then applying the medial rotation to the tibial followed by extension, the examiner can test the entire posterior aspect of the meniscus from the posterior horn to the middle segment. To test the medial meniscus, the examiner performs the same procedure with the knee laterally rotated. [1]
