Pg 791. Irwig L, Tosteson AN, Gatsonis C, et al. Be aware of the validity issues surrounding this test. 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. That is usually the journal article where the information was first stated. Clinical Rehabilitation, 22(2), 143-61. This trade-off between sensitivity and specificity makes it important that they be considered jointly27. 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 results support the use of both varus stress radiographs and MRI in diagnosing FCL injuries, because MRI is more sensitive in diagnosing an acute FCL tear, and varus stress radiographs are more sensitive in diagnosing a chronic FCL tear. LaPrade RF, DePhillipo NN, Cram TR, Cinque ME, Kennedy MI, Dornan GJ, O'Brien LT. Am J Sports Med. No valgus or varus stress is applied. ZmZjN2MzNzdhZDFlZWY2OGI0YWExNTViZjA5ZDc3OTA3MTJmYTYyOGFmMGEw 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. The acute tears frequently result from sports injuries where there is a twisting motion on the partially flexed, weight-bearing knee.[3]. Knee Sensitivity and Specificity: Flashcards | Quizlet 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. MjI0NTIxNTI4MWM3YmNjNGMwMDU2Mjk4ZWM1MzcyMDNkZTAyYmNhMDljZTU1 Sensitivity, specificity, and likelihood ratios (LR) of the McMurray's test with confidence intervals (CI). St. Louis, MO: Saunders Elsevier;2008. Jaeschke RZ, Meade MO, Guyatt GH, Keenan SP, Cook DJ. Walters J, editor. While palpating the lateral joint line, the examiner should apply a varus force to the patient's knee. 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 sensitivity and specificity of the McMurray's test reported in the studies identified in this review vary widely (Table (Table5).5). The reference lists in review articles were cross-checked and any possibility of name/term variations was queried using MEDLINE and PUBMED. [4] The popliteus tendon is deep to the LCL, seperating it from the lateral meniscus. In: Campbell's Operative Orthopaedics. This review identified that the McMurray's test is of limited clinical value due to relatively low sensitivity, with modified tests (associated with the traditional McMurray's test) having higher diagnostic accuracy and thus these may be more useful clinically. eCollection 2018 May. Symptoms related to an intra-articular knee pathology. . Cape Town: University of Cape Town, 2010. Varus stress testing was performed in 20 of flexion, and testing in extension was not done. The incidence of LCL injuries are relatively low (6%) when compared to other knee injuries. How to use diagnostic test articles in the intensive care unit: Diagnosing weanability using f/Vt. [8], Mechanism of injury: (for more information, see the page on LCL injuries)[4], Patient position: Legs crossed with ankle resting on opposite knee (90 knee flexion, hip abduction and external rotation). The Valgus Stress Test for LCL injuries has hardly been evaluated regarding its diagnostic accuracy. YzQ2ZWY3MDkyMmRjMWVjYzY3ODhjNTExZjU4NGIzMTJjNjA3ZDA5Mzk3NTFl Review of meniscal injury and associated sports. Oberlander MA, Shalvoy RM, Hughston JC. McMurray clearly indicated that the test that bears his name is only relevant for tears in the posterior portion of the cartilage (McMurray, 1942, cited in Corea et al4). 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. Federal government websites often end in .gov or .mil. Reid MC, Lachs MS, Feinstein AR. government site.

The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Some studies have attempted to compare the diagnostic value of the McMurray's test to that of modified tests. 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. Moreover, the ACL stabilizes the knee's rotation under varus or valgus stress. Varus Stress Test - Physical Therapy Haven The knee is first in full extension, and then it is slightly (20-30 degrees) so that it is unlocked.1. A 95% CI is the most commonly used and indicates a range of values within which the population value would lie with 95% certainty. Consequently, it is likely that the accuracy of meniscal testing demonstrated by this study is artificially high compared to studies with a wider inclusion criteria. IR of the tibia + Varus stress = lateral meniscus, ER of the tibia + Valgus stress = medial meniscus. YWQ2ODI0ODM5NzE5MzVlYTlmMTRmMWEzM2NlYmU4OTViYTkwOTBmNjVjZGFj 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%. The agreed quality for each paper is included in Table Table33. Positive likelihood ratios presented in the studies reviewed generally indicated small to moderate shifts in probability (0.828.86) in that a positive test will indicate true meniscal pathology although the studies with the highest methodological quality demonstrated likelihood ratios considered to indicate moderate improvements in the probability that this will be the case3,4. 1st ed. Electronic databases (Medline, CINhAL, AMED, SPORTSDiscus, and SCOPUS) were searched from March 1980 to May 2008. Malanga GA, Andrus S, Nadler SF, McLean J. Merriman L, Turner W. Assessment of the Lower Limb. PDF ssslideshare.com If the varus stress test is positive at 20, but negative at 0, only the LCL is torn. Of the four studies that demonstrated the highest shifts in probability, only Corea et al4 and Akseki et al3 contained calculable CIs, which were relatively narrow (Table (Table55). There . 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. During the maneuver, the joint line is palpated both medially and laterally. The test has therefore often been reported to be of limited value in current clinical practice. Waldman,S.D.

A positive result at both 0 and 20 indicate cruciate ligament involvement. Treadmill stress tests should not be part of "routine health check Elbow Varus Instability Stress TestLateral Collateral Ligament An official website of the United States government. Saunders Elsevier. Winters K, Tregonning R. Reliability of magnetic resonance imaging of the traumatic knee as determined by arthroscopy. Unlike the medial meniscus, which is attached to the medial ligament, the lateral meniscus is not attached to the lateral ligament. Eleven studies met the inclusion criteria. The fibular or lateral collateral ligament (LCL) is a cord-like band and acts as the primary varus stabilizer of the knee. The LCL acts as a secondary stabilizer to anterior and posterior tibial translation when the cruciate ligaments are torn. Sensitivity is the probability of a positive test result in someone with the pathology, whereas specificity is the probability of a negative test result in someone without the pathology.6Traditionally, tests which have high sensitivity values are able to correctly identify individuals with the pathology; thus, if the examiner obtains a negative In this position the iliotibial band relaxes and makes the LCL easier to isolate. The inclusion of patients with different pathologies would make the results of studies more generalizable to the clinical setting. Simmel DL, Samsa GP, Matchar DB. 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. 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.

Described a modified version (Ege's test) but no description of McMurray's. Human Kinetics, 2008. The final two studies20,21 limited their study population to patients suspected of meniscal injury. Referred from GP/A&E with suspected cruciate ligament or meniscal pathology. FOIA The external validity of a study is largely dependent on the study population. Read more, Physiopedia 2023 | Physiopedia is a registered charity in the UK, no. Both arthroscopy and MRI have been used as a gold standard measure for detection of meniscal injuries in knees. 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. Epub 2018 Jul 27.
