Neuromusculoskeletal examination assessment: A handbook for therapists. Other signs that have been used to denote a positive test include the production of pain, a clunk, or a pop. Clipboard, Search History, and several other advanced features are temporarily unavailable. Bethesda, MD 20894, Web Policies YWU3NTg0YTg5NzcxMzE4M2I5NjZiYzgxNzlkYjQyNmRjYjE1OWNjZjJmNzVh How likely a positive test result is in people who have the disease or dysfunction as compared to how likely it is in those who do not have the disease or dysfunction. The McMurray's test, as described in Corea et al4, was designed to detect tears in the posterior segment of the meniscus. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). J Sport Rehabil. Your access to this site was blocked by Wordfence, a security provider, who protects sites from malicious activity. 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. 4th Edition. N2IwYjAxYmE3NzM4ZmE2MTE5MTMyY2Q0M2I3NTQ5YjlkMzU3ODI3ODIyNzg0 The LCL acts as a secondary stabilizer to anterior and posterior tibial translation when the cruciate ligaments are torn. The .gov means its official. Elbow Varus Instability Stress TestLateral Collateral Ligament Also described a weight-bearing modification of McMurray's (Thessaly test), n/m for McMurray's, but joint line discomfort and possibly a sensation of locking or catching for Thessaly test. eCollection 2019 Feb. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. Therefore, this study aimed to determine the differences between varus and valgus arthritic knees in the response to conservative treatment. any of these symptoms can indicate a compromised medial or lateral meniscus. Take the leg and bring it in 30 Flexion (MLPP) and use a cushion or edge of the bed so the patient can relax. Varus stress radiographs were determined to be more sensitive in diagnosing FCL injuries compared with MRI, with an overall sensitivity of 70% compared with 66%, respectively. However, in general, the CI limits are relatively narrow over all. Am J Roentgenol. Noble J, Erat K. In defence of the meniscus: A prospective study of 200 menisectomy patients. Philadelphia: Elsevier, 2016; 2121-2297. Symptoms related to an intra-articular knee pathology.

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. Elsevier Health Sciences, 2014. YzM5MWNkYzMyMjQ0ZmU4MDdjZjg2NzYxZjhlMGI2N2RmMGI3ODExOWFmMDdl Three studies in this review compared the McMurray's test to modified versions that incorporated the added components of varus/valgus stress and axial compression.

YzZhYjViODEyOTFlYzkyIn0= Kennedy MI, Akamefula R, DePhillipo NN, Logan CA, Peebles L, LaPrade RF. PDF ssslideshare.com Obviously, if the test is performed differently and/or the interpretation of a positive test is not the same, the demonstrated accuracy of the test cannot be compared. Also described a modified version (the KKU compression-rotation test), Medial & Lateral combined = meniscal tear, Generate large and often conclusive shifts in probability, Generate small but sometimes important shifts in probability, Alter probability to a small and rarely important degree. 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. Malanga GA, Andrus S, Nadler SF, McLean J. Merriman L, Turner W. Assessment of the Lower Limb. National Center for Biotechnology Information Kurosaka M, Yagi M, Yoshiya S, Muratsu H, Mizuno K. Effcacy of the axially loaded pivot shift test for the diagnosis of a meniscal tear. They rated the sensitivity at 25% and could not report any specificity . Flow diagram of literature screening process. Consider the use of modifications of the test for improved validity. One study5 performed the test after the arthroscopy and did not state if the examiner was blinded to these results. Clinically, we do not know whether a patient has the condition before the diagnostic test (arthroscopy or MRI) is performed. [6] When the knee is extended, the LCL is stretched. Evidence-Based Medicine: How to Practice and Teach EBM. Because they were investigating this weight-bearing test as well, the authors excluded any patients who presented within six weeks of trauma and those unable to bear weight or unable to squat. Background and Objectives: Clinically, it is beneficial to determine the knee osteoarthritis (OA) subtype that responds well to conservative treatments. Solomon DH, Simel DL, Bates DW, Katz JN, Schafter JL. Studies investigating the validity of diagnostic tests such as the McMurray's compare the findings of that test with a reference (gold) standard that has demonstrated validity11. Partial Controlled Early Postoperative Weightbearing Versus Nonweightbearing After Reconstruction of the Fibular (Lateral) Collateral Ligament: A Randomized Controlled Trial and Equivalence Analysis. 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 site is secure. The confidence interval (CI) attests to the precision of this estimate11. YTY1NDM4NjNkYzAwMmMxNGU2MjgwMmMzODFlMTZkZmQyYjRmNTAzM2RkZWY4 [11] Sensitivity: 25% . Varus stress testing was performed in 20 of flexion, and testing in extension was not done. Guidelines for meta-analyses evaluating diagnostic tests. Four studies demonstrated that a positive test alters the probability to only a small, rarely important degree5,6,25, suggesting uncertainty that a positive test will indicate meniscal pathology (Table (Table5).5). 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. Interactive Content (Direct Video Demonstration, PubMed articles), Statistical Values for all Special Tests from the latest research, Currently on Version 6.0 Free lifetime updates. They commented that the lack of intertester agreement may have been due to differences in the amount of force produced. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. Studies of specificity and sensitivity have demonstrated varied values as a result of poor methodological quality[7] A recent meta-analysis reports sensitivity and specificity to be 70% and 71%. A recent evidence-based guideline for the management of acute soft tissue injuries to the knee has recommended that joint line tenderness is the only reliable clinical indicator of meniscal pathology2. 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. Table Table55 shows the LR+ and LR for the 11 studies included within this review with 95% CIs. Irwig L, Tosteson AN, Gatsonis C, et al. Gursoy S, Perry AK, Dandu N, Singh H, Vadhera AS, Yanke A, LaPrade RF, Chahla J. Orthop J Sports Med. 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. Described a modified version (Medial-Lateral Grind test) but no description of McMurray's. Notes Maximum dorsiflexion locks the subtalar joint and improves the sensitivity of this test. Those that do not include consecutive patients and those that exclude different pathologies may have biased results. The technical storage or access that is used exclusively for statistical purposes. Similarly, Corea et al4 included consecutive patients who were clinically diagnosed as having torn menisci based on a number of signs and symptoms including locking, a positive McMurray's test, painful clicks, and giving way. The remaining four studies failed to mention what denoted a positive test (Table (Table4).4). Some studies have attempted to compare the diagnostic value of the McMurray's test to that of modified tests. Generally, the McMurray's test has relatively high specificity and low sensitivity. Karachalios et al21 incorrectly added valgus or varus stress as a component of the McMurray's. Kane PW, Cinque ME, Moatshe G, Chahla J, DePhillipo NN, Provencher MT, LaPrade RF. The modified weight-bearing test showed a higher LR+ and a lower LR than the McMurray's test (Table (Table7).7). Consecutive patients with knee pain of at least one year's duration that warranted arthroscopic investigation. Review of meniscal injury and associated sports. Epub 2018 Jul 17. Clinical Rehabilitation, 22(2), 143-61. Comparable sensitivity and specificity were shown in regards to the Thessaly test, 85.4% and 54%, respectively. Published by Elsevier Inc. All rights reserved. Bethesda, MD 20894, Web Policies Accessibility Sensitivity and specificity of diagnosing FCL injuries on MRI were determined based on review by a fellowship-trained musculoskeletal radiologist, blinded to the pathology associated with each patient (FCL injury vs control), and compared with the gold standard of examination under anesthesia, followed by surgical confirmation of an FCL tear at the time of FCL reconstruction. Varus Stress Test [1] Magee DJ. 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. Arthroscopy has demonstrated an accuracy between 93% and 96%12. To eliminate this, the knee is held in 30 degrees of flexion. YmQ4NDJhMzZkOWUyMDUwNzAxN2M3ZjVhOGYyYmU0ZDVkYWUxNWM0ZGFhMTFi Rose NE, Gold SM. Petty NJ. ZmFjMDhjZmYyOWRiNWU2YjhhMWNhYjFiNTU5YTI5ODM3MTY1ODYwYzc2NmFi and transmitted securely. The majority of studies did not report intertester or intratester reliability of the McMurray's test. 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. Houten: Bohn Stafleu Van Loghum, 2005. 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). Methods: Patients identified as needing arthroscopy excluding those with intra-articular fracture, neurological or degenerative disorders. Saunders. When refering to evidence in academic writing, you should always try to reference the primary (original) source. aAssociate Professor, health & Rehabilitation Research Centre, School of Rehabilitation and Occupation Studies, AUT University, Auckland, New Zealand, bSenior Lecturer, School of Rehabilitation and Occupation Studies, Auckland University of Technology, Auckland, New Zealand, cHead of School of Rehabilitation and Occupation Studies, Auckland University of Technology, Auckland, New Zealand, dSchool of Physiotherapy, Auckland University of Technology, Auckland, New Zealand. Referred from GP/A&E with suspected cruciate ligament or meniscal pathology. Background: Functional hallux limitus (FHL) refers to dorsiflexion hallux mobility limitation when the first metatarsal head is under loading conditions but not in the unloaded state. 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. A recent literature review on composite testing of the diagnostic tests for the meniscus reported reasonable sensitivity and specificity when the findings of a number of tests are combined31. 2nd ed. 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. One of the search terms used was McMurray$ test$. Fowler and Lubliner22 had a similarly broad population in that they included consecutive patients who warranted arthroscopic examination for any reason. The predictive value of Thve clinical signs in the evaluation of meniscal pathology. Whenever suspecting a posterolateral complex injury, one has to carefully perform a valgus stress test in 0 degrees and 30 degrees. Modified McMurray's to include valgus/varus stress. Specificity: the ability of a test to correctly identify people without the disease. The ligament lies laterally and posteriorly along the joint line. followers, 277k Diagnosis of acute knee ligament injuries: The value of stress radiography compared with clinical examination, stability, under anesthesia and arthroscopic or operative findings.
