McMurray test

McMurray test




The McMurray test, is also known as the McMurray circumduction test


It is used to evaluate individuals for tears in the meniscus of the knee.


A meniscus tear may cause a tag of the meniscus which may become jammed between the joint surfaces.


The knee is held by one hand, which is placed along the joint line, and flexed to complete flexion while the foot is held by the sole of the foot with the other hand. 


The leg is then rotated internally while extending the knee to 90 degrees of flexion. 


If a thud or  click is felt along with pain, this constitutes a positive McMurray test for a tear in the posterior portion of the lateral meniscus. 


Am external rotation of the leg tests the posterior portion of the medial meniscus.


The sensitivity of the McMurray test for medial meniscus tears is 53% and the specificity is 59%. 


When clinical test results are  compared with arthroscopic and/or arthrotomy findings:


The clinical test had a sensitivity of 58.5%, a up to 97% specificity of a positive result for meniscal tears.
