The STARD checklist contains 25 items that help to make a judgment about potential bias in the study and appraisal of the applicability of the findings. Copyright 2018 Arthroscopy Association of North America. Meserve BB, Cleland JA, Boucher CT. A meta-analysis examining clinical test utilities for assessing meniscal injury. Anderson AF, Lipscomb AB. (PDF) Physical examination of the elbow, what is the evidence? A Statistical evaluation of McMurray's test in the clinical diagnosis of meniscus injuries. Apply slight lateral rotation and perform passive adduction at the knee joint and thus put stress on the LCL. Human Kinetics, 2008. Flow diagram of literature screening process. The use of the STARD tool is also a limitation. 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. The https:// ensures that you are connecting to the Operational definitions of diagnostic accuracy terms used in the studies investigating validity of McMurray's test for meniscal pathology (modified from Powell & huijbregts10). 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. McMurray's test is used to determine the presence of a meniscal tear within the knee. Consider reproduction of pain during the test as a positive test, not just the reproduction of a. Prospective evaluation of the McMurray test. The clinician hold the patient's ankle with one hand, while the other hand is on the lateral condyle of the femur. Sensitivity: the ability of a test to correctly identify patients with a disease. IR of the tibia + Varus stress = lateral meniscus. Based on the STARD scoring of each paper, it is possible to make a qualitative assessment about the methodological quality. Painful conditions of the knee, inPain Management Vol 1.,2007. The sensitivity was 87% for the medial meniscus but only 46% for the lateral meniscus13. Medline and CINAHL search strategy via OVID. That is usually the journal article where the information was first stated. Interpretation: If the knee joint adducts greater than normal (compared to the unaffected leg), the test is positive. 13th ed. Clipboard, Search History, and several other advanced features are temporarily unavailable.

Diagnosis of acute knee ligament injuries: The value of stress radiography compared with clinical examination, stability, under anesthesia and arthroscopic or operative findings. Manoeuvres assessing the posterolateral structures include the varus stress test, dial test, the posterolateral drawer, the external rotation recurvatum test, heel height test and the reverse pivot shift. Described a modified version (Medial-Lateral Grind test) but no description of McMurray's. Analysis of the quality of studies that evaluate the validity and accuracy of tests, such as the McMurray's test, is difficult if key information regarding the design, conduct, and analysis of the study are not reported by the authors9. Kennedy MI, Akamefula R, DePhillipo NN, Logan CA, Peebles L, LaPrade RF. MRI has also shown to be highly reliable, but due to its expensive cost, they are less frequently used.

Patients suspected of having a meniscal tear on the basis of history and mechanism of injury excluding those with multiple injuries, history of knee surgery, early clinical and radiographic signs of osteoarthritis, articular cartilage injuries, neurological and musculoskeletal degenerative disorders, disorders of the synovium, acute injuries (less than 4 weeks post-trauma), and any abnormal findings on conventional radiographs. Buy online Fucidin no RX - Trusted Fucidin no RX Clinical Rehabilitation, 22(2), 143-61. McMurrays Test - Physiopedia Arthrosc Tech. The best statistics for summarizing usefulness of a diagnostic test appear to be likelihood ratios (LR)17. Likelihood ratios overcome some of the problems involved with sensitivity and specificity values by summarizing the information contained in these values in a manner that can be used to quantify shifts in probability once the meniscal test results are known28. NDkyMTlmYzMyYjdlN2RlZTQ2MjFiMjc5NGRhOWNjYWI3NTliM2NhYzM3YWNj Varus Stress Test - Physical Therapy Haven Both (Sensitivity - Out & Specificity - In) + finding: medial or lateral joint line discomfort or have a sense of locking/catching in knee. 2018 Nov 1;27(6):596-600. doi: 10.1123/jsr.2016-0188. One of the search terms used was McMurray$ test$. Once again, this affects the generalizability of the findings. Patient in supine. Solomon DH, Simel DL, Bates DW, Katz JN, Schafter JL. Gursoy S, Perry AK, Dandu N, Singh H, Vadhera AS, Yanke A, LaPrade RF, Chahla J. Orthop J Sports Med. 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. NTcwOGRhYWNmMWQyOTg0NjE1M2QwNTU5MTk0Nzk2OTQzMGU3YmUxODlhZjM0 sharing sensitive information, make sure youre on a federal The Medial-Lateral Grind test had a higher LR+ (Table (Table7)7) when compared to the McMurray's test; however, its CIs were extremely wide, bringing into question the precision of this estimate of reliability (Table (Table7).7). Hegedus EJ, Cook C, Hasselblad V, Goode A, McCrory DC. Under the original description of the test, a thud or a click felt by the examiner (and sometimes heard) while performing the test was considered positive (McMurray as cited in Corea et al4). Consider the findings of this test in conjunction with those of other tests to enhance the likelihood of a correct diagnosis such as joint line tenderness. Top Contributors - Rachael Lowe, Admin, Adrian Shaji, Kim Jackson, Evan Thomas, Amanda Ager, Kai A. Sigel, Wanda van Niekerk, Tony Lowe, Tyler Shultz and WikiSysop, Meniscus tears are the most common injury of the knee. LaPrade RF, DePhillipo NN, Cram TR, Cinque ME, Kennedy MI, Dornan GJ, O'Brien LT. Am J Sports Med. At the proximal level this ligament is closely related to the joint capsule, without having direct contact, as it is separated by fat pad, The insertion is augmented by the iliotibial band. The examiner should passively bend the affected leg to about 30 degrees of flexion. Six of the studies within this review included consecutive patients (Table (Table4).4). Results: Be aware of the validity issues surrounding this test. Selection bias may occur when study subjects are not representative of the population on whom the test is typically applied in practice and can affect the results of a study11. The Valgus Stress Test for LCL injuries has hardly been evaluated regarding its diagnostic accuracy. Moore KL, Dalley AF, Agur AMR. The statistical measures of sensitivity, specificity, and likelihood ratios were calculated from the information provided in the studies.

Three of the studies in this review considered a positive test to be the reproduction of a palpable thud or click4,6,22 (Table (Table4).4). Karachalios et al21 incorrectly added valgus or varus stress as a component of the McMurray's. An assessment for one-plane medial instability (gapping of the tibia away from the femur on the medial side). Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. The sensitivity of diagnosing an FCL injury based on varus stress radiographs was also determined. Consecutive patients with knee pain of at least one year's duration that warranted arthroscopic investigation. Examining diagnostic tests: An evidence-based perspective. 2nd ed. When pooled together using the bivariate random effects model (BREM), the sensitivity value of the 8 studies was 0.2 and the specificity value was 0.88. NzM3NDQ2NDMzYThiNjlhNjA0M2M3MzVlMWFhYmE5ZDI3ZTI0YTIyZGIyNWM4 Consecutive patients suspected of having meniscal tears presenting for arthroscopy: acute and chronic (ligament injuries excluded). 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. Hegedus EJ, Cook C, Hasselblad V, Goode A, McCrory DC. Campbell SE, Sanders TG, Morrison WB. 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. The inclusion of patients with different pathologies would make the results of studies more generalizable to the clinical setting. Sackett D, Richardson S, Rosenberg W, Haynes RB. 5, pp. A 95% CI is the most commonly used and indicates a range of values within which the population value would lie with 95% certainty. Blinding of the clinicians from the results of the diagnostic test was either not mentioned or not performed in all of the studies in this review except for the study by Karachalios et al21. Waldman,S.D. MR imaging of meniscal cysts: incidence, location, and clinical significance. Accuracy is the percentage of subjects who are correctly identified as either having or not having a meniscal tear. Physical examination of the knee, inThe Sports Medicine Resource Manual, Editors: Seidenberg, P.H & Beutler, A..I. In contrast, the paper by Sae-Jung et al24 found sensitivity for medial and lateral menisci of 70% and 68%, respectively, and specificity values for medial and lateral menisci of 60.7% and 47.8%, respectively. Accessibility Sae-Jung et al24 considered pain or a clicking sound to be a positive test. Table Table55 shows the LR+ and LR for the 11 studies included within this review with 95% CIs. Walters J, editor. Currently, a triple phase technium-99 bone scan (scintigraphy) is the most accurate method of diagnosing stress fractures with a sensitivity of 100% and specificity of 76%. Usually medial angulation of both femur and tibia is involved. Sensitivity and specificity of this test are only 38% and 41%, respectively. Purpose: The Varus Stress Test is used to assess the integrity of the LCL or lateral collateral ligament of the knee. Other studies3,5,19 commented that greater clinical experience may affect the results of the test but they did not provide any statistical evidence to support this assertion. The test is performed at 0 and 20-30, so the knee joint is in the closed packed position. The accuracy of the clinical knee examination documented by arthroscopy: A prospective study. the tibia moves away from the femur an excessive amount on the lateral aspect of the leg). Mariani PP, Adriani E, Maresca G, Mazzola CG. YTY1NDM4NjNkYzAwMmMxNGU2MjgwMmMzODFlMTZkZmQyYjRmNTAzM2RkZWY4 Performed at 900 of knee flexion, and has a sensitivity of 90% and a specificity of 99% Isolated PCL translate > 10-12mm in neutral and >6-8mm in internal rotation. AP and lateral radiographic images of a SE-4 fracture - ResearchGate 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. To some degree, this is achieved by sensitivity and specificity, which provide useful information for interpreting the results of diagnostic tests. Were the raters blinded to the results of the other test? Akseki et al3 included consecutive patients with symptoms related to intra-articular knee pathology although how this was determined was not described. Address all correspondence and requests for reprints to: Wayne Hing. Measures of efficacy include accuracy, sensitivity, and specificity. In this position the iliotibial band relaxes and makes the LCL easier to isolate. Schulzer M. Diagnostic tests: A statistical review. So, little is known about the validity of this test. YmRhYTcyZWFhNTQ5OTM0YWYwODRjZDU1OWU3ZjBjNmMyMjA4NTcxZTRmMDYw Rose NE, Gold SM. 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. Towards complete and accurate reporting of studies of diagnostic accuracy: The STARD initiative. YzZhYjViODEyOTFlYzkyIn0= Consecutive patients scheduled for menisectomy; acute and chronic.
