IR of the tibia + Varus stress = lateral meniscus. 8600 Rockville Pike Read more, Physiopedia 2023 | Physiopedia is a registered charity in the UK, no. All had persistent symptoms at least 8 weeks post-injury. The sensitivity and specificity of the McMurray's test reported in the studies identified in this review vary widely (Table (Table5).5). eyJtZXNzYWdlIjoiMDAzMWIwNTU1ZDk0ZjIzMGU1NDkwYzhmOWYxZTk0YWI3 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). Disease paper 2 .pdf - Jade Smith BIOL 2301 Sec. 001 In: DeLee & Drez's Orthopaedic Sports Medicine. 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. Five studies compared modified versions of the test to McMurray's3,5,6,21,24 (Table (Table33). government site. While palpating the lateral joint line, the examiner should apply a varus force to the patient's knee. Some of the studies did not separate the data for medial from that of lateral meniscal testing5,6,22,25. A total of 232 patients were included: 98 patients in the FCL tear group (mean age: 33.6 12.2 years) and 134 patients in the control group (mean age: 44.0 17.2 years). Based on MRI, overall specificity was 68%. Measures of efficacy include accuracy, sensitivity, and specificity. The sensitivity was 87% for the medial meniscus but only 46% for the lateral meniscus13. On the basis of the results of the studies in this review, it seems that intertester reliability using the McMurray's test is low. Physical Examination of the Knee | Musculoskeletal Key Electronic databases (Medline, CINhAL, AMED, SPORTSDiscus, and SCOPUS) were searched from March 1980 to May 2008. Consider the use of modifications of the test for improved validity. Grade II: The joint space opens 3-5 mm more than the contralateral side in 20 degrees of knee flexion and less than 2 mm more than the normal knee in full extension. Examining diagnostic tests: An evidence-based perspective. -----BEGIN REPORT----- Six of the studies within this review included consecutive patients (Table (Table4).4). Before Knee injuries. Acute injuries excluded. Reliability Study of Diagnostic Tests for Functional Hallux Limitus Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Additionally, the single photon-emission CT scan is receiving a lot . So, little is known about the validity of this test. Human Kinetics, 2008. Review of meniscal injury and associated sports. Would you like email updates of new search results? The final two studies20,21 limited their study population to patients suspected of meniscal injury. The statistical measures of sensitivity, specificity, and likelihood ratios were calculated from the information provided in the studies. Varus Stress Test of the Knee | Lateral Collateral Ligament Test Towards complete and accurate reporting of studies of diagnostic accuracy: The STARD initiative. Am J Roentgenol. Malanga GA, Andrus S, Nadler SF, McLean J. 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. Biomechanics and physical examination of the - ScienceDirect MGQ5MzQyZWI5MjJjMjUxYjFhM2E1ZjQ5NTgzMzdmNTY4NmYwZWM1ZWQ3YTU3 [11] Sensitivity: 25% . Physical examination of the knee: A review of the original test description and scientific validity of common orthopedic 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). ZmY3MzI2ODBmYTBhMDEzNzY3YmRkZjU0MDRhM2U2ODliZTFmOWMzYWI0MWI5 Schulzer M. Diagnostic tests: A statistical review. These findings are contrasted by those of Karachalios et al21, who reported a 95% agreement for both intra- and intertester reliability for all of the clinical tests they employed. [1]. M2YxNmU0NGVlMWUwYjVjMDY4MzIwZjY3OTJmYTc0YzFhMDIyMDAwNTVhNGJm 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. Background and Objectives: Clinically, it is beneficial to determine the knee osteoarthritis (OA) subtype that responds well to conservative treatments. 2018 May 2;6(5):2325967118770170. doi: 10.1177/2325967118770170. 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. Knee, McMurray's, Meniscal, Reliability, Sensitivity, Specificity, Testing, Validity. Clinical Orthopedic Examination Findings in the Lower Extremity A positive result at both 0 and 20 indicate cruciate ligament involvement. 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). In addition to the database searches, personal files were hand-searched by the authors for publications and relevant material.

A consensus method was used to discuss and resolve discrepancies between the markings of each paper between the three reviewers. YzA0Nzk1ZjQxYjY5Mzg4MWUwNDRlODM0NDRiNzZiM2I4OWVhNTQ1YmVlMDNj Sensitivity and specificity of a test. Sensitivity and specificity of this test are only 38% and 41%, respectively. YWQ2ODI0ODM5NzE5MzVlYTlmMTRmMWEzM2NlYmU4OTViYTkwOTBmNjVjZGFj any of these symptoms can indicate a compromised medial or lateral meniscus. Your access to this site was blocked by Wordfence, a security provider, who protects sites from malicious activity. 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%. 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.

Bethesda, MD 20894, Web Policies 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. [12] If the varus stress test is positive at 20, but negative at 0, only the LCL is torn. Mariani et al30 have suggested that the differences in anatomical attachments of the two menisci contribute to these variations in sensitivity and specificity of diagnostic tests30. Each of these studies demonstrated improved diagnostic accuracy of these modified tests compared to the original McMurray's; however, they concluded that the modified tests should be used as well, as rather than as an alternative to other diagnostic tests3,5,6. It is primary restraint to varus rotation from 0-30 of knee flexion. Specificity is the proportion of patients without the condition who have a negative test result and indicates the ability to use a test to recognize when the condition is absent11. Specificity: the ability of a test to correctly identify people without the disease. YTY1NDM4NjNkYzAwMmMxNGU2MjgwMmMzODFlMTZkZmQyYjRmNTAzM2RkZWY4 YmQ4NDJhMzZkOWUyMDUwNzAxN2M3ZjVhOGYyYmU0ZDVkYWUxNWM0ZGFhMTFi 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. This was a purposeful strategy designed to enhance their ability to determine the true sensitivity and specificity of the McMurray's test in a population that reflects the symptomatic knee cohort that presents clinically. In an analysis of 20 available studies, the mean sensitivity and specificity of the anterior drawer test were 38% to 81% in awake patients and 63% to 91% in anesthetized patients, respectively. 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). No valgus or varus stress is applied. Consecutive patients with knee pain of at least one year's duration that warranted arthroscopic investigation. The majority of studies did not report intertester or intratester reliability of the McMurray's test. MRI has also shown to be highly reliable, but due to its expensive cost, they are less frequently used. 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. The most sensitive test used in the diagnostics of medial meniscus lesions was the McMurray test, which showed a sensitivity of 87.5% with 52% specificity. 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. They also fail to take into account pre-test probability. Kennedy MI, Akamefula R, DePhillipo NN, Logan CA, Peebles L, LaPrade RF. FOIA [5] The LCL further splits the biceps femoris into two parts. 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.
