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. How to appraise a diagnostic test. Rose NE, Gold SM. 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. There is conflicting evidence in the literature over the accuracy of MRI. [2] Harilainen A. Physical examination of the knee, inThe Sports Medicine Resource Manual, Editors: Seidenberg, P.H & Beutler, A..I. M2MwN2QyM2QzMGFjZjQ3MDgzMGRiYzAyMmRlZDc3MTAxODc4MDdhNzcyZWMz 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 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). One problem with these modified tests is that they appear to have all been evaluated by the creators of the tests, which to some degree challenges the validity of the research. The Heel Height Test: A Novel Tool for the Detection of Combined Anterior Cruciate Ligament and Fibular Collateral Ligament Tears. 2017 Mar;101(Suppl 1):23-35. doi: 10.1007/s12306-017-0460-5. Symptoms related to an intra-articular knee pathology. Neuromusculoskeletal examination assessment: A handbook for therapists. The incidence of LCL injuries are relatively low (6%) when compared to other knee injuries. The preliminary nature of this tool also means that a more narrative review of the validity and accuracy of the tests has been presented. Although sensitivity and specificity values provide useful information, they work against the direction of clinical testing11. YmRhYTcyZWFhNTQ5OTM0YWYwODRjZDU1OWU3ZjBjNmMyMjA4NTcxZTRmMDYw The studies that compared the diagnostic accuracy of the McMurray's test with that of modified versions of the test showed enhanced diagnostic accuracy for the modified tests. Varus stress testing was performed in 20 of flexion, and testing in extension was not done. Epub 2017 Aug 16. When refering to evidence in academic writing, you should always try to reference the primary (original) source. Therefore, this study aimed to determine the differences between varus and valgus arthritic knees in the response to conservative treatment. A positive test is considered to be a thud or click that can sometimes be heard but can always be felt4 (Figure (Figure11). 2017 Dec;33(12):2177-2181. doi: 10.1016/j.arthro.2017.06.028. Corea JR, Moussa M, Al Othman A. McMurray's test tested. Moreover, the ACL stabilizes the knee's rotation under varus or valgus stress. 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. National Library of Medicine 1173185. I concluded that joint line tenderness as a test for lateral meniscal tears is accurate (96%), sensitive (89%), and specific (97%). 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 reference lists in review articles were cross-checked and any possibility of name/term variations was queried using MEDLINE and PUBMED. varus stress test - Medical Dictionary They rated the sensitivity at 25% and could not report any specificity percentage. Bethesda, MD 20894, Web Policies ZDFjNGQ5ZTg3MjdkZDAxOTE5MTYxNDQ3NmIzYzNhZjE4ZjAwNDc4M2NiMzEz Likelihood ratios overcome some of the problems involved with sensitivity and specificity values by summarizing the information contained in these values in a manner that can be used to quantify shifts in probability once the meniscal test results are known28. 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. However, this provisional diagnosis was also based on other symptoms that one might consider could be associated with pathologies other than meniscal tears, e.g., pain, recurrent effusion, muscle wasting, and instability. The review suggests that modifications of the interpretation of a positive test to include reproduction of pain either as well as or on its own may enhance the validity of the test.

True negative: the person does not have the disease and the test is negative. An official website of the United States government. Once again, this affects the generalizability of the findings. Philadelphia: Elsevier, 2016; 2121-2297. There is conflicting evidence with respect to the effect of the presence of an associated anterior cruciate ligament (ACL) deficiency. 1987; 76: 269-273. A) AND B): The McMurray's test: Figure 1a) the tibia rotated on the femur into full internal rotation and Figure 1b) the tibia rotated on the femur into full external rotation.
