1173185. Applied Sciences | Free Full-Text | Comparison of Diagnostic - MDPI Consecutive patients awaiting elective arthroscopy for suspected meniscal or other conditions based on history and physical examination. These studies have hypothesized that by incorporating aspects of varus/valgus stress and/or axial loading into the original McMurray's test, there is an increase in diagnostic value3,5,6. A total of 232 patients were included: 98 patients in the FCL tear group (mean age: 33.6 12.2 years) and 134 patients in the control group (mean age: 44.0 17.2 years). Douglas I, McDermott Meniscal tears. The Heel Height Test: A Novel Tool for the Detection of Combined Anterior Cruciate Ligament and Fibular Collateral Ligament Tears. 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. OGNkMmFkZGY0YjIxNzkxN2RkOTg3YzgzMTdiYjY1OGMxMzA2NThmZjIxNGNi Consecutive patients. . [1]. Miller RH, Azar FM. Would you like email updates of new search results? In testing the accuracy of a clinical test like the McMurray's test, ideally the study participants should consist of individuals who would be likely to undergo the test in clinical practice and who have a reasonable chance of having the condition16. ZTEyZjE4YTgwNjcwY2IwOWVkNmUwZDVjODFiMTExMDBhN2MyOGE5NDdhYWUz Slocum Drawer Test: Inconclusive Crossover Test: Inconclusive Pivot Shift Test: Sensitivity: 60% Specificity: 96% The https:// ensures that you are connecting to the An official website of the United States government. 133k Evans et al23 compared a senior examiner with over 10 years experience to a medical student who had recently been taught the technique whereas Karachalios et al21 compared two experienced orthopaedic surgeons with two inexperienced residents. Be aware of the validity issues surrounding this test. Both (Sensitivity - Out & Specificity - In) + finding: medial or lateral joint line discomfort or have a sense of locking/catching in knee. 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. Further, subjects who are positive on the reference standard should reflect a continuum of severity, whereas those who are negative should have conditions commonly confused with meniscal tears17. 2008 Saunders. Magee, D.J Chapter 12: Knee, in Orthopedic Physical Assessment. Sensitivity and specificity values fail to do this11. The wide range of positive likelihood ratios (0.828.86) make it difficult to draw any conclusions about the actual magnitude of this ratio. St. Louis, MO: Saunders Elsevier;2008. Knee Sensitivity and Specificity: Flashcards | Quizlet One study used a palpable thud and/or pain23, and two studies used a palpable click and/or pain3,20. Test (b): Disease Status test (b) results *Positive Negative Present 18 7 25 absent 2 73 75 total 20 80 100 Calculate the sensitivity, specificity, positive predictive values, and negative predictive values for each test. Physical examination of the knee, inThe Sports Medicine Resource Manual, Editors: Seidenberg, P.H & Beutler, A..I. National Library of Medicine 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. M2EwZWY0Zjg3ZDdlZTMzNDhjY2EwMzdkMmRjZmQ1M2M1OTI3ZDRiZDk0NzYx This trade-off between sensitivity and specificity makes it important that they be considered jointly27. Physical examination of the knee: a review of the original test description and scientific validity of common orthopedic tests. A recent meta-analysis illustrates the difference in test characteristics when performed on patients under anesthesia. Patient in supine. [2] Harilainen A. 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). N2IwYjAxYmE3NzM4ZmE2MTE5MTMyY2Q0M2I3NTQ5YjlkMzU3ODI3ODIyNzg0 Purpose: 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. The sensitivity and specificity of the clinical tests and magnetic resonance (MR) imaging are reviewed because these parameters vary, and an understanding of the diagnostic utility of both the clinical and imaging tests is important in accurately formulating a definitive diagnosis. Both imaging modalities are recommended to diagnose both acute and chronic FCL injuries. Posterior drawer test Posterior sag test (godfrey test) Quadriceps active test Dial test Varus/valgus stress . A recent systematic review reported a diagnostic accuracy between 56 - 84% 5.A prospective cohort study of 213 patients found poor sensitivity for medial and lateral meniscus tears of 48% and 65% respectively 6.Conversely specificity for medial and lateral meniscal tears was high, 94% . [5], The LCL stabilizes the lateral side of the knee joint, mainly in varus stress and posterolateral rotation of the tibia relative to the femur. Federal government websites often end in .gov or .mil. However, of those that have made this distinction, there is some consensus that the McMurray's test has higher sensitivity with respect to medial meniscal tears and higher specificity with lateral meniscal tears3,4,19,20,24. 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. Valgus Stress Test Four authors stated that they used the McMurray's test but did not describe the actual testing procedure3,5,19,25. As previously documented in the literature10, the definition and calculation of statistical measures of concurrent criterion-validity are based on the absence or agreement between the clinical test and the gold standard test. Diagnosis of acute knee ligament injuries: The value of stress radiography compared with clinical examination, stability, under anesthesia and arthroscopic or operative findings. A positive test is considered to be a thud or click that can sometimes be heard but can always be felt4 (Figure (Figure11). Based on the STARD scoring of each paper, it is possible to make a qualitative assessment about the methodological quality. Varus Stress Test [1] Magee DJ. Epub 2018 Jul 27. In most cases Physiopedia articles are a secondary source and so should not be used as references. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); If you want to assess the integrity of the medial collateral ligament (MCL), check out the Valgus Stress Test of the Knee. Hegedus EJ, Cook C, Hasselblad V, Goode A, McCrory DC. In chronic injuries, this test has a sensitivity of 92% and a specificity of 91%, but not in acute injuries. 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. ODFlNzFkZTQ2MDZmOTVkM2Q1MjEzNzY5YTlmZTU2MTRmYWFkYzY2ZmRmNzlj 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. The technical storage or access that is used exclusively for anonymous statistical purposes. These results have been supported by Karachalios et al21, who compared another weight-bearing modification (the Thessaly test) of the McMurray's with the original test. Described a modified version (Medial-Lateral Grind test) but no description of McMurray's. The McMurray's test, as described in Corea et al4, was designed to detect tears in the posterior segment of the meniscus. Agreement regarding which articles to read in full was determined by consensus. varus stress test: A test of ligament laxity, where a passive force is exerted on a joint that, in the presence of ligamentous insufficiency, would cause the lateral joint space to open, e.g., lateral collateral ligament of the knee and radial collateral ligament of the elbow. Acute patients (< 6 weeks) excluded. With a sensitivity of 86% and a specificity of 95%, . As the knee goes into flexion, the LCL loses its significance and influence as a varus-stabilizing structure. When refering to evidence in academic writing, you should always try to reference the primary (original) source. Philadelphia: Elsevier, 2016; 2121-2297. Sensitivity figures vary from 16%88%, while specificity figures vary from 20%98% (Table (Table5).5). The test is first done with the knee in full extension and then with the knee in 20-30 degrees of flexion. This was also discussed by Evans et al23, who attributed their low sensitivity rates to wide patient entry criteria including differing pathologies (Table (Table44). Epub 2018 Jul 17. Varus Stress Test of the Knee: Genu Varum (aka bow-leggedness, bandiness, bandy-leg, and tibia vara), is a physical deformity marked by (outward) bowing of the lower leg in relation to the thigh, giving the appearance of an archer's bow. 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. Disease paper 2 .pdf - Jade Smith BIOL 2301 Sec. 001 Articles may have been missed based on the omission of certain search phrases or the use of a single search phrase as used in this case. Methodology and description of the 11 studies investigating validity and clinical accuracy of McMurray's test for meniscal pathology.

A positive result at both 0 and 20 indicate cruciate ligament involvement. Evidence. If you believe that this Physiopedia article is the primary source for the information you are refering to, you can use the button below to access a related citation statement. 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. Mariani et al30 have suggested that the differences in anatomical attachments of the two menisci contribute to these variations in sensitivity and specificity of diagnostic tests30. Clinical Diagnostic Tests Versus MRI Diagnosis of ACL Tears. Fritz JM, Wainner RS. Cinque ME, Geeslin AG, Chahla J, Moatshe G, Pogorzelski J, DePhillipo NN, LaPrade RF. MGY4MmExODg4MDUwZTk2NzUzNjQ0OTMxYjkxN2QwYjQ5MmMxODdmMWU4MDdi The Valgus Test of the knee is performed with the patient lies in the supine position. The inclusion of patients with different pathologies would make the results of studies more generalizable to the clinical setting. Oberlander MA, Shalvoy RM, Hughston JC.

Effcacy of the axially loaded pivot shift test for the diagnosis of a meniscal tear. The accurate diagnosis of meniscal pathology on the basis of the findings of such tests is often difficult. N2MzZTc5OGFkMzAwZTZmM2Y1YWFiZTJjMjM3OGNkMmNkM2E4OTYzZWFkMjA5 YzA0Nzk1ZjQxYjY5Mzg4MWUwNDRlODM0NDRiNzZiM2I4OWVhNTQ1YmVlMDNj Normal elbow range of motion is from 0 at full extension to 140 of flexion, with a range of 30 to 130 required for Valgus instability Valgus instability arises through injuries to the MCL, specifically the AMCL. OWFmOGE3YWY0OWM1ZWIzOTU5Mjg5Y2I4ODIwZmU1MmQyZWRhMmUxY2ZlMGU3 Five studies compared modified versions of the test to McMurray's3,5,6,21,24 (Table (Table33).

The predictive value of Thve clinical signs in the evaluation of meniscal pathology. If you believe Wordfence should be allowing you access to this site, please let them know using the steps below so they can investigate why this is happening. Varus Test | Special Tests Other signs that have been used to denote a positive test include the production of pain, a clunk, or a pop. Intertester reliability of clinical judgements of medial knee ligament integrity. The description should include the exact details of the test's application and the criteria used to determine positive and negative results11. The purpose of this paper was to assess the literature investigating the validity and diagnostic accuracy of the McMurray's test (and modifications) for determining meniscal pathology of the knee so that conclusions could be drawn regarding its clinical usefulness as a test. Confidence intervals could not be calculated32 from the data provided by these authors making it difficult to assess the accuracy of results. Useful tests should produce large shifts in probability once the result of the test is known. All patients who underwent an isolated FCL or combined anterior cruciate ligament (ACL)/FCL reconstruction by a single surgeon between 2010 and 2017 with preoperative varus stress radiographs and magnetic resonance imaging (MRI) were included in this study. It seems logical that those studies that include both pain and a click should have higher diagnostic value as compared to studies that just use one sign or the other. Guidelines for meta-analyses evaluating diagnostic tests. Increased Accuracy of Varus Stress Radiographs Versus Magnetic - PubMed Therefore, articles were assessed using the STARD (Standards for Reporting of Diagnostic Accuracy) checklist of methodological quality9, which uses established criteria for quality assessment of different research formats10. Whenever suspecting a posterolateral complex injury, one has to carefully perform a valgus stress test in 0 degrees and 30 degrees. Measures of efficacy include accuracy, sensitivity, and specificity. H Nalwad; M Agarwal; B N Muddu; M Smith; and Mr. J K Borill (2006). ZDIwNGI3MGM0NDMzZmMxM2YxZDdmZWM0YmE5MDI5OWJiMmE4MmFhZTdkODE1 eCollection 2019 Feb. The .gov means its official. Clinically, we do not know whether a patient has the condition before the diagnostic test (arthroscopy or MRI) is performed. Harilainen A. Anterior cruciate ligament reconstruction: MR imaging findings. A 95% CI is the most commonly used and indicates a range of values within which the population value would lie with 95% certainty. In general, sensitivity figures are much lower than specificity and the CI limits are wider. The review also highlights the idea that modified versions of the test seem to be more valid than the original version. So, little is known about the validity of this test. The clinician hold the patient's ankle with one hand, while the other hand is on the lateral condyle of the femur. Each of these studies demonstrated improved diagnostic accuracy of these modified tests compared to the original McMurray's; however, they concluded that the modified tests should be used as well, as rather than as an alternative to other diagnostic tests3,5,6. followers. The technical storage or access that is used exclusively for statistical purposes. Varus stress testing was performed in 20 of flexion, and testing in extension was not done. Copyright 2018 Arthroscopy Association of North America. High specificity indicates that a test can be used for including a condition when it is positive26. However, other studies have shown MRI to be no more accurate than clinical examination for the diagnosis of meniscal tears14,15. However, for medial meniscal tears, rates are lower. 1, This website is powered by SportsEngine's. Meserve BB, Cleland JA, Boucher TR. Inclusion in an NLM database does not imply endorsement of, or agreement with, St. Louis, MO: Saunders Elsevier;2008. . National Center for Biotechnology Information This lack of consensus in the literature highlights the risk that the criteria indicating a positive test can influence the test outcome, irrespective of whether the test was performed in the same manner on the same patient. 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. Bookshelf This means that tests rarely have both high sensitivity and specificity. YjQ3NDViZGE1YWVjODEwNTIzYzIyMmY1YjViMDhhNGI3Y2YyNTI4NmMwMjli 1st ed. I concluded that joint line tenderness as a test for lateral meniscal tears is accurate (96%), sensitive (89%), and specific (97%). Corea JR, Moussa M, Al Othman A. McMurray's test tested. Sensitivity figures were higher than specificity for three studies5,20,25 (Table (Table5).5). Human Kinetics, 2008. Take the leg and bring it in 30 Flexion (MLPP) and use a cushion or edge of the bed so the patient can relax. A prospective evaluation of a test for lateral meniscal tears. 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.
