Relatively narrow confidence intervals also attest to the reliability of these two studies3,4 (Table (Table55). Unfortunately, it is not possible to accurately determine the precision of reliability of the Boeree and Ackroyd19 study as CIs could not be calculated. This is not surprising given the complicated nature of the technique and the difficulty in controlling the amount and direction of forces across testers. Karachalios et al21 incorrectly added valgus or varus stress as a component of the McMurray's. These authors suggested that this increase in sensitivity and specificity compared to previous studies was due to their broader definition of a positive test, i.e., reproduction of a click or pain3; however, this does not explain the similar findings of Corea et al4 in which only a click was indicative of a positive test.

Biomechanics and physical examination of the - ScienceDirect Read more, Physiopedia 2023 | Physiopedia is a registered charity in the UK, no. 24 General examination included carrying angle (normal, valgus,. 4th Edition. Further, the description of the test itself should be well explained, and improving intertester reliability in the future would increase the validity of the studies. 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).

Zappia M, Capasso R, Berritto D, Maggialetti N, Varelli C, D'Agosto G, Martino MT, Carbone M, Brunese L. Musculoskelet Surg. Measures of efficacy include accuracy, sensitivity, and specificity. A recent meta-analysis illustrates the difference in test characteristics when performed on patients under anesthesia. Does the patient have a torn meniscus of ligament of the knee? sharing sensitive information, make sure youre on a federal One of the tests was the valgus stress test, particularly at 30 of knee flexion. An official website of the United States government. 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% . any of these symptoms can indicate a compromised medial or lateral meniscus. No mention acute/chronic. Based on MRI, overall specificity was 68%. Moreover, the ACL stabilizes the knee's rotation under varus or valgus stress. Statistical evaluation of McMurray's test in the clinical diagnosis of meniscus injuries. Comparison of likelihood ratio's for McMurray's test with modified tests. Human Kinetics, 2008. The Valgus Test of the knee is performed with the patient lies in the supine position. Baker PE, Peckham AC, Pupparo F, Sanborn JC. Excluding any with past history of trauma and any with associated fractures, serious arthrosis, previous history of knee surgery or discoid meniscus identified arthroscopically. Value of the physical examination. 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. Were the raters blinded to the results of the other test? Four authors stated that they used the McMurray's test but did not describe the actual testing procedure3,5,19,25. IR of the tibia + Varus stress = lateral meniscus. In addition to the database searches, personal files were hand-searched by the authors for publications and relevant material. [11] Sensitivity: 25% . Clinical assessment of meniscal pathology in the knee has proven difficult due to the wide number of tests available and variations in their interpretation and application. OWFmOGE3YWY0OWM1ZWIzOTU5Mjg5Y2I4ODIwZmU1MmQyZWRhMmUxY2ZlMGU3 Varus Stress Test of the Knee | Lateral Collateral Ligament Injury Patients diagnosed with meniscal lesions (based on symptoms including pain, recurrent edema, giving way, joint clicks, or block to movement) having arthroscopic surgery. These authors demonstrated significantly larger (better) positive likelihood ratios and significantly smaller (better) negative likelihood ratios than the McMurray's. 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). The test has therefore often been reported to be of limited value in current clinical practice. 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. Assessment of the menisci and cruciate ligaments: An audit of clinical practice. How to use diagnostic test articles in the intensive care unit: Diagnosing weanability using f/Vt. Purpose: The varus stress test shows a lateral joint line gap. YTY1NDM4NjNkYzAwMmMxNGU2MjgwMmMzODFlMTZkZmQyYjRmNTAzM2RkZWY4 One of the search terms used was McMurray$ test$. Sensitivity can be defined as the proportion of patients with the condition who have a positive test result and represents the ability of the test to recognize the condition when present11. The fibular or lateral collateral ligament (LCL) is a cord-like band and acts as the primary varus stabilizer of the knee. Evans et al23 concluded that examiner experience had little effect on the accuracy of the diagnosis; however, they noted that the student examiner demonstrated a significant association (p = 0.002) between the diagnosis of a medial meniscus tear and reproduction of a medial thud, while the experienced examiner demonstrated a significant association between this diagnosis and the reproduction of pain (p = 0.008) or a medial sensation (p = 0.001). An assessment for one-plane medial instability (gapping of the tibia away from the femur on the medial side). We hypothesized that valgus arthritic knees would respond better to conservative treatment than varus . Notes Maximum dorsiflexion locks the subtalar joint and improves the sensitivity of this test. 8600 Rockville Pike Download scientific diagram | AP and lateral radiographic images of a SE-4 fracture consisting of a spiral or oblique fracture laterally with a combination of an avulsion fracture medially. 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. 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). Diagnostic accuracy of a new clinical test (the fiessaly Test) for early detection of meniscal tears. 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 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. 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. National Library of Medicine 269-273). Collectively, these studies indicate that there is little consensus in the reported measures of validity of the McMurray's test and that this is mostly due to limitations in the methodological quality of the studies that were assessed. 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. To evaluate the diagnostic accuracy of magnetic resonance imaging and varus stress radiographs for fibular collateral ligament (FCL) tears, and compare these modalities to intraoperative findings. Guidelines for meta-analyses evaluating diagnostic tests. Hegedus EJ, Cook C, Hasselblad V, Goode A, McCrory DC. Background and Objectives: Clinically, it is beneficial to determine the knee osteoarthritis (OA) subtype that responds well to conservative treatments. Sensitivity and specificity values fail to do this11. True positive: the person has the disease and the test is positive. Accuracy of 3 Diagnostic Tests for Anterior Cruciate Ligament Tears Am J Roentgenol. The accuracy measure has limited usefulness in that it does not distinguish between the diagnostic value of positive and negative results11. Reliability Study of Diagnostic Tests for Functional Hallux Limitus ZmY3MzI2ODBmYTBhMDEzNzY3YmRkZjU0MDRhM2U2ODliZTFmOWMzYWI0MWI5 Epub 2017 Feb 14. Epub 2017 Aug 16. Results also indicate that testing for medial meniscal pathology is more sensitive than testing for lateral; however, tests for lateral meniscal pathology are more specific than tests for medial pathology3,4,19. Moore KL, Dalley AF, Agur AMR. More recent research has shown that modifications to the original McMurray's test may have better validity and diagnostic accuracy than the original McMurray's test3,58. 8600 Rockville Pike Cape Town: University of Cape Town, 2010. Grade III: The joint space opens 5 . McMurray. 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. This trade-off between sensitivity and specificity makes it important that they be considered jointly27. The IR of the tibia followed by extension, the examiner can test the entire posterior horn to the middle segment of the meniscus. 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. Physical examination consisted of general elbow examination and specific examination of the distal biceps based on literature. NzM3NDQ2NDMzYThiNjlhNjA0M2M3MzVlMWFhYmE5ZDI3ZTI0YTIyZGIyNWM4 This generic search strategy was then combined with a subject-specific strategy (Table (Table1).1). MjUwZDBiZTEwYzA5YjkxZGRiYzI0YTE2MzY2ODI3ZDhjODQyYjNiZjU1YTU5 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. NWYxMjQ3NzE3ZWM2MGI5ODE2MGE0ZWZkNmNjZmQxNWM0M2JiYjFlZTJlNWQ5 Described a modified version (Medial-Lateral Grind test) but no description of McMurray's. The reference lists in review articles were cross-checked and any possibility of name/term variations was queried using MEDLINE and PUBMED. Sensitivity figures were higher than specificity for three studies5,20,25 (Table (Table5).5). Karachalios T, Hantes M, Zibis AH, Zachos V, Karantanas AH, Malizos KN. The description of a test within a study should be sufficient to enable replication of the test by practitioners and subsequent researchers. Methodological scores on the STARD (Standards for Reporting of Diagnostic Accuracy) yielded scores from 10/25 to 20/25. 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.
