New York: Appleton-Century-Crofts, 1976. The varying definitions of a positive McMurray's test are also likely to have contributed to the variability of the results demonstrated by the studies reviewed. [11] Sensitivity: 25% . The studies by Akseki et al3, Corea et al4, and Manzotti et al20 revealed negative likelihood ratios that are slightly lower than the other studies. The anterior portion of the meniscus is not easily tested because the pressure to that part of the meniscus is not as great. Once again, this affects the generalizability of the findings. Karachalios T, Hantes M, Zibis AH, Zachos V, Karantanas AH, Malizos KN. This is not surprising given the complicated nature of the technique and the difficulty in controlling the amount and direction of forces across testers. The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. One problem with these modified tests is that they appear to have all been evaluated by the creators of the tests, which to some degree challenges the validity of the research. ZTU5MGVlOWM4MDcwMGE2YmJiZjNjZTBiMjQ2N2E5OTFmNTliZDgyYzc4ZjQ0 Specificity: 100% Valgus Stress Test: Sensitivity: 91% Specificity: 17% Varus Stress Test: Sensitivity: 25-77% Specificity: 98-99% Quadriceps Active Test: Sensitivity: 54-99% Specificity: 97-100% Posterior Sag Test: Inconclusive. ZTEyZjE4YTgwNjcwY2IwOWVkNmUwZDVjODFiMTExMDBhN2MyOGE5NDdhYWUz Evans et al23 demonstrated a low level of agreement between the two examiners with intertester agreements ranging from poor for reproduction of a medial sensation (Kappa = 0.10) to fair (K = +0.38) for lateral pain. They rated the sensitivity at 25% and could not report any specificity . The review also highlights the idea that modified versions of the test seem to be more valid than the original version. Methodology and description of the 11 studies investigating validity and clinical accuracy of McMurray's test for meniscal pathology. The reference lists in review articles were cross-checked and any possibility of name/term variations was queried using MEDLINE and PUBMED. Reliability Study of Diagnostic Tests for Functional Hallux Limitus The accuracy of joint line tenderness by physical examination in the Sae-Jung S, Jirarattanaphochai K, Benjasil T. KKU knee compression-rotation test for detection of meniscal tears: A comparative study of its diagnostic accuracy with the McMurray test. Be aware of the validity issues surrounding this test. In one of these studies, the CIs are extremely wide5. DOI https://doi.org/10.1016/B978-1-4160-3197-0.X1000-2. Five studies compared modified versions of the test to McMurray's3,5,6,21,24 (Table (Table33). MDU1NWE1Nzc5OGVjNTczOGU2OWUyMWYxYmY3Njk5ZTdlMDEwZTQ3MTY0Zjdm Bearing these findings in mind, the following recommendations can be made for the clinician: This review has demonstrated that the intertester reliability and sensitivity of the McMurray's test is relatively low; however, it has also highlighted that it can be a relatively specific test, especially with respect to the lateral meniscus. Evaluation of Knee Instability in Acute Ligamentous Injuries. Another Systematic review study by Braun Schwieterman found that the sensitivity and specificity of the medial talar tilt stress test was 50% and 88 % respectively. The clinician hold the patient's ankle with one hand, while the other hand is on the lateral condyle of the femur. Saunders. Ocassionally, the LCL is congenitally absent. M2NhODMyZGZjNTEwMzAzY2JkMWI0MTUwM2I3NjNjN2RjYmY4NmEyNWE1ZjZk Useful tests should produce large shifts in probability once the result of the test is known. Fibular collateral ligament and the posterolateral corner. Anderson AF, Lipscomb AB. Valgus and Varus Stress Test [1] Magee DJ. One of the search terms used was McMurray$ test$. So, little is known about the validity of this test. (2007)Physical examination tests for assessing a torn meniscus in the knee: a systematic review with meta-analysis. Although these authors mentioned that the examiners were blinded to the results of the MRI, they did not make it clear if the examiners knew that there were a similar number of normals and symptomatic subjects included in the study or if they knew which group each individual subject belonged to. The review suggests that modifications of the interpretation of a positive test to include reproduction of pain either as well as or on its own may enhance the validity of the test. Waldman,S.D. Moreover, the ACL stabilizes the knee's rotation under varus or valgus stress. ZmFjMDhjZmYyOWRiNWU2YjhhMWNhYjFiNTU5YTI5ODM3MTY1ODYwYzc2NmFi Each test is repeated with the knee in full extension. Consecutive patients scheduled for menisectomy; acute and chronic. Studies that have evaluated the sensitivity and specificity of individual clinical tests to detect ligamentous injury, . Partial Controlled Early Postoperative Weightbearing Versus Nonweightbearing After Reconstruction of the Fibular (Lateral) Collateral Ligament: A Randomized Controlled Trial and Equivalence Analysis. Physical examination of the knee, inThe Sports Medicine Resource Manual, Editors: Seidenberg, P.H & Beutler, A..I. Sensitivity and specificity of this test are only 38% and 41%, respectively. Baker PE, Peckham AC, Pupparo F, Sanborn JC. The inclusion of patients with different pathologies would make the results of studies more generalizable to the clinical setting. Posterior drawer test Posterior sag test (godfrey test) Quadriceps active test Dial test Varus/valgus stress . This means that tests rarely have both high sensitivity and specificity. Valgus and Varus test of the knee can be graded by the following 1: Grade I: The joint space opening is within 2 mm of the contralateral side. Sae-Jung et al24 considered pain or a clicking sound to be a positive test. NWI4Njg2Y2FiM2QzZGFjNjA2MjRhYTcxMTY2NmVkZmYzNTMwZDdiNTk4YTcy Future research should concentrate on building a strong methodological base incorporating large samples of consecutive patients with commonly confused pathologies. MWU3NjBlM2FlMDU2YWM3ODA4ZGIyZTNjODFkOWU2ZDBkMGNiYzRhZjE2MGRk Specificity is the proportion of patients without the condition who have a negative test result and indicates the ability to use a test to recognize when the condition is absent11. An example of this would be as follows: If the McMurray's test had a LR+ of 9.2 for a particular study, a positive McMurray's test is 9.2 times more likely to occur in patients with a meniscal tear than in those without one29. Accessibility Am J Sports Med.

YmRhYTcyZWFhNTQ5OTM0YWYwODRjZDU1OWU3ZjBjNmMyMjA4NTcxZTRmMDYw Piantanida, A.N. The Valgus Stress Test for LCL injuries has hardly been evaluated regarding its diagnostic accuracy. Valgus Stress Test. Some of the studies did not separate the data for medial from that of lateral meniscal testing5,6,22,25. Bethesda, MD 20894, Web Policies A recent study by Akseki et al3 reported high combined sensitivity and specificity figures (63% and 83%, respectively) and relatively narrow confidence intervals (Table (Table5).5). The site is secure. YzFjZGMyZmVmOTJjNWQ2NWYyNDVkNDE1OWM3Yzg5NjE2MWNhYTY1ZGZlNGYw Further, the description of the test itself should be well explained, and improving intertester reliability in the future would increase the validity of the studies. All had persistent symptoms at least 8 weeks post-injury. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). Please enable it to take advantage of the complete set of features! The low sensitivity figures would indicate that in general, a negative test result is not reliable in ruling out meniscal pathology and a torn meniscus would likely be missed if the McMurray's test was the sole determinant of pathology. MR imaging of meniscal cysts: incidence, location, and clinical significance. Patients diagnosed with meniscal lesions (based on symptoms including pain, recurrent edema, giving way, joint clicks, or block to movement) having arthroscopic surgery. Finally, further independent research needs to compare the McMurray's test with modified tests to confirm the apparent superiority of these tests over the McMurray's test. However, this provisional diagnosis was also based on other symptoms that one might consider could be associated with pathologies other than meniscal tears, e.g., pain, recurrent effusion, muscle wasting, and instability. A guide to the interpretation of likelihood ratio (LR) values. Differences in the type of tear have been suggested as influencing the result of clinical tests; however, no detailed investigation of this issue exists in the current literature3. Clinical diagnosis of meniscal tears: Description of a new manipulative test. The ligament lies laterally and posteriorly along the joint line. Varus Stress Test Purpose: To assess the integrity of the LCL. These represent small but sometimes important shifts in probability and the stronger methodology of these studies is reflected by the relatively narrow CIs (Table (Table55). These comments are also supported by the findings of a recent meta-analysis carried out by Hegedus et al7 and Meserve et al8. McMurray's test is used to determine the presence of a meniscal tear within the knee. Based on the STARD scoring of each paper, it is possible to make a qualitative assessment about the methodological quality. An assessment for one-plane lateral instability (i.e. Three independent reviewers assessed each of the papers included in the review, and an overall STARD score of methodological quality was determined for each paper. Mariani PP, Adriani E, Maresca G, Mazzola CG. Clinial oriented anatomy. Higher specificity figures denote that in general when the McMurray's test is positive, it is fairly reliable for ruling in meniscal pathology. Current Orthopaedics. In: Campbell's Operative Orthopaedics. Consecutive patients awaiting elective arthroscopy for suspected meniscal or other conditions based on history and physical examination. This was also discussed by Evans et al23, who attributed their low sensitivity rates to wide patient entry criteria including differing pathologies (Table (Table44). Excluding any with past history of trauma and any with associated fractures, serious arthrosis, previous history of knee surgery or discoid meniscus identified arthroscopically. Top Contributors - Rachael Lowe, Admin, Adrian Shaji, Kim Jackson, Evan Thomas, Amanda Ager, Kai A.

YWQ2ODI0ODM5NzE5MzVlYTlmMTRmMWEzM2NlYmU4OTViYTkwOTBmNjVjZGFj Manzotti A, Baiguini P, Locatelli A, et al. Both arthroscopy and MRI have been used as a gold standard measure for detection of meniscal injuries in knees. The test is first done with the knee in full extension and then with the knee in 20-30 degrees of flexion. Irwig L, Tosteson AN, Gatsonis C, et al.

Methods: TP=true positive, FP=false positive, FN=false negative, TN=true negative. 5, pp. AP and lateral radiographic images of a SE-4 fracture - ResearchGate True negative: the person does not have the disease and the test is negative. Varus Stress Test - Physical Therapy Haven 3rd edition. Address all correspondence and requests for reprints to: Wayne Hing. Operational definitions of diagnostic accuracy terms used in the studies investigating validity of McMurray's test for meniscal pathology (modified from Powell & huijbregts10). Measures of efficacy include accuracy, sensitivity, and specificity. Sensitivity and specificity values infer the probability of a correct test, given the result of the reference standard11. IR of the tibia + Varus stress = lateral meniscus. Only one study by Harilainen et al. Simmel DL, Samsa GP, Matchar DB. Varus Stress Test of the Knee | Lateral Collateral Ligament Injury If the varus stress test is positive at 20, but negative at 0, only the LCL is torn. Grade III: The joint space opens 5 . Reverse Pivot Shift Sign of Jakob, Hassler, and Stubli. These authors considered the overall accuracy of the axially loaded pivot shift test to be higher than that of the McMurray's test (Table (Table7).7). Published by Elsevier Inc. All rights reserved. Evans PJ, Bell GD, Frank CY. Before Patients who underwent arthroscopy to assess suspected meniscal or meniscal together with ACL injuries. Sensitivity can be defined as the proportion of patients with the condition who have a positive test result and represents the ability of the test to recognize the condition when present11.
