McMurray's test tested

Abstract

We studied the validity of McMurray's test for a torn meniscus in 93 patients. The clinical test results were compared with arthroscopic and/or arthrotomy findings as reference. The clinical test had a sensitivity of 58.5%, a specificity of 93.4%, and the predictive value of a positive result was 82.6%. The test therefore seems to be of limited value in current clinical practice.

“…In addition, they were asked for effusion, catching, giving way, and locking, to determine clinically healing of the repaired menisci. To be scored as having a clinically stable knee the patient had to have a pain grade of no more than three; no postoperative history of locking, giving way, or catching; a painless and negative McMurray's maneuver [7]; and no subsequent surgical procedure. If the examined knee failed to satisfy all of these criteria it was categorized as being clinically unstable [17].…”

Validity of the McMurray's Test and Modified Versions of the Test: A Systematic Literature Review

“…Of the studies evaluated in this review, six used the original description of the McMurray's test 4,6,20,[22][23][24] . Four authors stated that they used the McMurray's test but did not describe the actual testing procedure 3,5,19,25 .…”

“…Four authors stated that they used the McMurray's test but did not describe the actual testing procedure 3,5,19,25 . Karachalios et al 21 Three of the studies in this review considered a positive test to be the reproduction of a palpable thud or click 4,6,22 ( Table 4). One study used a palpable thud and/or pain 23 , and two studies used a palpable click and/or pain 3,20 .…”

“…The possibility of there being associated intra-articular pathology (such as anterior cruciate ligament rupture) confounds results, and the unknown validity, sensitivity, and specificity of the tests make it difficult for the clinician to be confident in making a definitive diagnosis 3 . The McMurray's test, as described in Corea et al 4 , was designed to detect tears in the posterior segment of the meniscus. It is performed by placing the knee beyond 90° of flexion and then rotating the tibia on the femur into full internal rotation to test the lateral meniscus, or full external rotation to test the medial meniscus.…”

“…During the maneuver, the joint line is palpated both medially and laterally. A positive test is considered to be a thud or click that can sometimes be heard but can always be felt 4 ( Figure 1). The findings of studies testing the validity of the McMurray's test have varied widely, mostly due to variations in the size and type of the study population as well as differences in description and application of the test 3 .…”
