Accuracy is the percentage of subjects who are correctly identified as either having or not having a meniscal tear. Evidence-Based Medicine: How to Practice and Teach EBM. In total, 11 studies have been included in this critical review. Anderson and Lipscomb5 compared the McMurray's test to a test termed the Medial-Lateral Grind test that included a varus/valgus component not included in the original McMurray's test. Based on MRI, overall specificity was 68%. Generally, the McMurray's test has relatively high specificity and low sensitivity. followers, 277k [9] When LCL is injured or torn, this cordlike band is not as noticeable as on the unaffected side. Results also indicate that testing for medial meniscal pathology is more sensitive than testing for lateral; however, tests for lateral meniscal pathology are more specific than tests for medial pathology3,4,19.

McMurray clearly indicated that the test that bears his name is only relevant for tears in the posterior portion of the cartilage (McMurray, 1942, cited in Corea et al4). Examining diagnostic tests: An evidence-based perspective. The proportion of people who do not have the disease or dysfunction who test negative. Clinically, we do not know whether a patient has the condition before the diagnostic test (arthroscopy or MRI) is performed. The same maneuvers are performed in gradually increasing degrees of knee flexion to progressively load more posterior segments of the menisci. Studies were included for analysis if they compared the McMurray's test with a gold standard of knee arthroscopy or magnetic resonance imaging (MRI). Although blinding was not mentioned in respect to the other studies, the majority required the clinical examination to be performed prior to the diagnostic arthroscopy, suggesting that the examiner would indeed be blinded to the results of the diagnostic test. 3rd edition. These authors excluded subjects with clinical or radiographic evidence of arthritis or fracture that would increase the accuracy of testing but decrease the generalizability of the findings. This generic search strategy was then combined with a subject-specific strategy (Table (Table1).1). Medline and CINAHL search strategy via OVID. Solomon DH, Simel DL, Bates DW, Katz JN, Schafter JL. Consequently, it is likely that the accuracy of meniscal testing demonstrated by this study is artificially high compared to studies with a wider inclusion criteria. Three studies used only one tester4,5,25, and two studies did not mention how many examiners were used3,24. Level of evidence: (2008) A meta-analysis examining clinical test utilities for assessing meniscal injury. Corea JR, Moussa M, Al Othman A. McMurray's test tested.

These comments are also supported by the findings of a recent meta-analysis carried out by Hegedus et al7 and Meserve et al8.
