However, for medial meniscal tears, rates are lower. Whiting WC, Zernicke RF. Purpose: The Varus Stress Test is used to assess the integrity of the LCL or lateral collateral ligament of the knee. Valgus and Varus Stress Test - Physical Therapy Haven 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. Diagnosis of acute knee ligament injuries: The value of stress radiography compared with clinical examination, stability, under anesthesia and arthroscopic or operative findings. Address all correspondence and requests for reprints to: Wayne Hing. Varus stress MRI in the refined assessment of the posterolateral corner of the knee joint. Clipboard, Search History, and several other advanced features are temporarily unavailable. The goal of the study was to evaluate 3 common manual tests (Buell, Dananberg, and Jack tests) for assessing first metatarsophalangeal joint (MPJ) mobility and determining the normal values needed to detect FHL . The wide range of positive likelihood ratios (0.828.86) make it difficult to draw any conclusions about the actual magnitude of this ratio. To some degree, this is achieved by sensitivity and specificity, which provide useful information for interpreting the results of diagnostic tests. If the CI is wide and contains values that are not clinically important, the usefulness of the measure may be questionable11. The reported incidence of ACL sprains and tears in the knee injuries. Based on chronicity of the injuries, MRI was more accurate for detecting acute FCL injuries than chronic injuries (P = .002), and varus stress radiographs were more accurate for detecting chronic FCL injuries than acute injuries (P = .041). PMC Evans et al23 used consecutive patients on a waiting list for arthroscopy for a variety of conditions including, but not limited to, suspected meniscal tears. Value of the physical examination. Referred from GP/A&E with suspected cruciate ligament or meniscal pathology. Common terms. The test is fairly solid. 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. Federal government websites often end in .gov or .mil. The final study by Sae-Jung et al24 compared a modified version to McMurray's added axial compression, similar to that applied by Kurosaka et al6 but without added valgus or varus stress. The test is performed at 0 and 20-30, so the knee joint is in the closed packed position. Corea JR, Moussa M, Al Othman A. McMurray's test tested. The assessment results for methodological quality has been presented under the following headings: the STARD analysis, reference standard, population differences, blinding, description and interpretation of test, inter-tester reliability, diagnostic accuracy and validity, sensitivity and specificity, likelihood ratios, and McMurray's test compared to modified versions of the test. Physical examination of the knee: a review of the original test description and scientific validity of common orthopedic tests. Moore KL, Dalley AF, Agur AMR. Canada. However, in general, the CI limits are relatively narrow over all. 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). Authors of 9 studies examined the Lachman test and reported sensitivity values ranging from 0.63-0.93 and specificity values ranging from 0.55-0.99. Sensitivity and specificity rely on a single threshold for classifying a test result as positive or negative. The fibular or lateral collateral ligament (LCL) is a cord-like band and acts as the primary varus stabilizer of the knee. YmQ4NDJhMzZkOWUyMDUwNzAxN2M3ZjVhOGYyYmU0ZDVkYWUxNWM0ZGFhMTFi Yedlinsky, N.T. MWQ3MmUzODg0NGJiYzhiODZlYmMxOGU3NzQ1ZTAwNmMxNTJjOTZiZDJlZGFi Bossuyt PM, Reitsma JB, Bruns DE, et al. Given the results of the multivariate regression in Question 1, write the regression equation associated with this study. 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. Based on MRI, overall specificity was 68%. Varus Stress Test - The Student Physical Therapist 2nd ed. The Diagnostic Accuracy of Clinical Tests for Stress Fractures Each test is repeated with the knee in full extension. 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. Comparable sensitivity and specificity were shown in regards to the Thessaly test, 85.4% and 54%, respectively. NCI CPTC Antibody Characterization Program. Six of the studies within this review included consecutive patients (Table (Table4).4). This is true in the case of the study by Akseki et al3 but not for the study by Evans et al23 (Tables (Tables44 and and55). [12] If the varus stress test is positive at 20, but negative at 0, only the LCL is torn. Philadelphia: Wolters Kluwer, 2010. Both imaging modalities are recommended to diagnose both acute and chronic FCL injuries. Orthop J Sports Med. Solomon DH, Simel DL, Bates DW, Katz JN, Schafter JL. When confidence intervals are not present, the CIs were incalculable due to absence of raw data. Diagnosis and treatment strategies of the multiligament injured knee: a The use of the STARD tool is also a limitation. Relatively narrow confidence intervals also attest to the reliability of these two studies3,4 (Table (Table55). This generic search strategy was then combined with a subject-specific strategy (Table (Table1).1). Likelihood Ratios with confidence: Sample size estimation for diagnostic test results. 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. NWYxMjQ3NzE3ZWM2MGI5ODE2MGE0ZWZkNmNjZmQxNWM0M2JiYjFlZTJlNWQ5 They commented that the lack of intertester agreement may have been due to differences in the amount of force produced. Talar Tilt Test 2023 | OrthoFixar Although the support of a clinical study is needed in order to make a definite conclusion, the dial test is probably not reliable in the presence of medial instability, DOI https://doi.org/10.1016/B978-1-4160-3197-0.X1000-2. any of these symptoms can indicate a compromised medial or lateral meniscus. 269-273). During the maneuver, the joint line is palpated both medially and laterally. followers, 277k In most cases Physiopedia articles are a secondary source and so should not be used as references.

The remaining four studies failed to mention what denoted a positive test (Table (Table4).4). A wide variety of clinical tests are used to diagnose meniscal pathology within the knee joint. LaPrade RF, DePhillipo NN, Cram TR, Cinque ME, Kennedy MI, Dornan GJ, O'Brien LT. Am J Sports Med. Sensitivity: 25%. Increased Accuracy of Varus Stress Radiographs Versus Magnetic Resonance Imaging in Diagnosing Fibular Collateral Ligament Grade III Tears. These authors also demonstrated that the Medial-Lateral Grind test had smaller (better) LR compared to the McMurray's test although the change in probability was still only small and should be considered rarely important (Table (Table77). N2MzZTc5OGFkMzAwZTZmM2Y1YWFiZTJjMjM3OGNkMmNkM2E4OTYzZWFkMjA5 Sackett D, Richardson S, Rosenberg W, Haynes RB. High sensitivity indicates that a test can be used for excluding a condition when it is negative, but it does not address the value of a positive test. 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). Oberlander MA, Shalvoy RM, Hughston JC. NzM3NDQ2NDMzYThiNjlhNjA0M2M3MzVlMWFhYmE5ZDI3ZTI0YTIyZGIyNWM4 YzQ2ZWY3MDkyMmRjMWVjYzY3ODhjNTExZjU4NGIzMTJjNjA3ZDA5Mzk3NTFl The test has therefore often been reported to be of limited value in current clinical practice. 24 General examination included carrying angle (normal, valgus,. One of the tests was the valgus stress test, particularly at 30 of knee flexion. Consecutive patients suspected of having meniscal tears presenting for arthroscopy: acute and chronic (ligament injuries excluded). Akseki et al3 compared the McMurray's test with a weight-bearing version of the McMurray's test that incorporated axial compression and varus/valgus stress, with the patient squatting down in internal and then external rotation (Ege's test). The four possible outcomes include true positive, a false positive, a false negative, and a true negative (see Table Table2).2). 2008 Saunders. The external validity of a study is largely dependent on the study population. 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 diagnosis3. Knee Examination: Overview, Periprocedural Care, Technique - Medscape Varus stress testing was performed in 20 of flexion, and testing in extension was not done. Clinial oriented anatomy. A prospective study comparing the accuracy of the clinical diagnosis of meniscal tears with magnetic resonance imaging and its effect on clinical outcome. Evaluation of knee instability in acute ligamentous injuries. eCollection 2022 Jun. Ciba M, Winkelmeyer EM, Schock J, Westfechtel S, Nolte T, Knobe M, Prescher A, Kuhl C, Truhn D, Nebelung S. Sci Rep. 2022 Jul 13;12(1):11858. doi: 10.1038/s41598-022-15787-2. A recent meta-analysis illustrates the difference in test characteristics when performed on patients under anesthesia. 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). [1] The therapist applies a valgus stress at the knee while the ankle is stabilized in slight lateral rotation either with the hand or with the leg held between the examiner's arm and trunk. A positive result at both 0 and 20 indicate cruciate ligament involvement. Acute injuries excluded. Schnke M, Schulte E, Schumacher U. Prometheus deel 1: Algemene anatomie en bewegingsapparaat. However, they only included patients who had had symptoms for at least one year, making extrapolation of their findings to the acute population challenging. Magee, D.J Chapter 12: Knee, in Orthopedic Physical Assessment. However, only Kurosaka et al6 and Evans et al23 made it clear that the examiners were not given any details about the subject's history so that they would not be influenced by this information. Painful conditions of the knee, inPain Management Vol 1.,2007. 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. Elbow Varus Instability Stress TestLateral Collateral Ligament ZDIwNGI3MGM0NDMzZmMxM2YxZDdmZWM0YmE5MDI5OWJiMmE4MmFhZTdkODE1 Notes Maximum dorsiflexion locks the subtalar joint and improves the sensitivity of this test. 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 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. They rated the sensitivity at 25% and could not report any specificity percentage. 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.

Although six studies used multiple testers, these did not provide statistics for reliability6,1923. 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%. The anterior portion of the meniscus is not easily tested because the pressure to that part of the meniscus is not as great. [11] Sensitivity: 25% . Arthroscopy. Elbow Valgus Stress Test 2023 | OrthoFixar Schulzer M. Diagnostic tests: A statistical review. Valgus Stress Test | Medial Collateral Ligament (MCL) Injury - Physiotutors The knee is first in full extension, and then it is slightly (20-30 degrees) so that it is unlocked.1. 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 diagnosis3. In general, sensitivity figures are much lower than specificity and the CI limits are wider. Disclaimer. It is important to take this into consideration when analyzing test results of studies that have used more than one examiner. So, little is known about the validity of this test. Electronic databases (Medline, CINhAL, AMED, SPORTSDiscus, and SCOPUS) were searched from March 1980 to May 2008. 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 accuracy of joint line tenderness by physical examination in the Am J Roentgenol. That is usually the journal article where the information was first stated. Arthroscopy has demonstrated an accuracy between 93% and 96%12. 1. In this position the iliotibial band relaxes and makes the LCL easier to isolate. In most cases Physiopedia articles are a secondary source and so should not be used as references.

Would you like email updates of new search results? Three studies used only one tester4,5,25, and two studies did not mention how many examiners were used3,24. The LCL acts as a secondary stabilizer to anterior and posterior tibial translation when the cruciate ligaments are torn. The Journal of Manual & Manipulative Therapy. This, along with the conclusions discussed above, suggests that the McMurray's test should be used as one of a combination of tests in the clinical setting3,22,23. Physical Examination of the Knee | Musculoskeletal Key 1st ed. For the varus stress test, the patient is in supine position and asked to relax. Campbell SE, Sanders TG, Morrison WB. Saunders. With a sensitivity of 86% and a specificity of 95%, . 1985;13(1):14. Kurosaka et al6 took the modification of the Medial-Lateral Grind test further by comparing the McMurray's test to a pivot shift test that not only had a component of varus/valgus stress but also included a component of axial loading. Purpose: The varus stress test shows a lateral joint line gap. This site needs JavaScript to work properly.
