However, various intra-articular lesions  may often produce similar symptoms. So, what kinds of symptoms are more  associated with a meniscal tear? Is MRI worth doing?\n        OBJECTIVE:  The aims of this study were to identify sensitive and specific clinical tests  and elements of patients\u2019 history with a high predictive value, and to assess  the combined diagnostic accuracy of sensitive and specific clinical tests and  elements of patients\u2019 history with  MRI.\n        METHODS:  Data from 281 consecutive knee arthroscopies to investigate and treat suspected  internal knee pathologies were retrospectively collected between March 2009 and  April 2010. The study group consisted of 262 knees. Statistically significant  factors in the clinical diagnosis of meniscal tears were screened by a  chi-square test. Logistic regression analysis was used to determine which  factors associated with meniscal tears found during arthroscopy. The diagnostic  values of MRI and the sensitive and specific clinical tests and elements of  patients\u2019 history with high predictive value for meniscal tears were  calculated.\n        RESULTS: The  overall diagnostic value of MRI for meniscal tears was: accuracy, 88.8%;  sensitivity, 95.7%; specificity, 75.8%; positive predictive value (PPV), 88.2%;  and negative predictive value (NPV), 90.4%. Giving way, locking and McMurray\u2019s  test were independent diagnostic factors with a predicted correct percentage of  80.0% (p&lt;0.05) for the diagnosis of meniscal tears found during  arthroscopy. Locking, McMurray\u2019s test and MRI increased the predicted correct percentage  of meniscal tears found during arthroscopy to 91.6% (p&lt;0.05). For  the diagnosis of meniscal tears found during arthroscopy, giving way, locking  and McMurray\u2019s test had the following values for accuracy (49.2, 60.9, 76),  sensitivity (43.5, 55.2, 75.8), specificity (84, 96, 76.9), PPV (94.4, 98.8,  95.1) and NPV (19.4, 25.8, 35.1). Combining MRI, the diagnostic values of  giving way, locking, and McMurray\u2019s test were: accuracy, 88.3,89.9,89.4;  sensitivity, 95.7,97.4,97.4; specificity, 74.2,75.8,74.2; PPV, 87.5,88.4,87.7;  and NPV, 90.2,94,93.9.\n        CONCLUSIONS:  Giving way, locking and McMurray\u2019s test are independent clinical diagnostic  factors for the diagnosis of meniscal tears. MRI has higher accuracy,  sensitivity and NPV for the diagnosis of meniscal tears than giving way,  locking and McMurray\u2019s test. The combination of giving way, locking, McMurray\u2019s  test and MRI for confirmation is typical for a meniscal lesion diagnosis. Based  on these findings, MRI should be used in a standard manner to detect meniscal  tears found during arthroscopy.<\/jats:p>","DOI":"10.4414\/smw.2011.13314","type":"journal-article","created":{"date-parts":[[2011,12,14]],"date-time":"2011-12-14T17:30:37Z","timestamp":1323883837000},"page":"w13314","source":"Crossref","is-referenced-by-count":19,"title":["Predicted  probability of meniscus tears: comparing history and physical examination with\u00a0MRI"],"prefix":"10.57187","volume":"141","author":[{"given":"R","family":"Yan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ZH","family":"Ji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YM","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"36756","published-online":{"date-parts":[[2011,12,5]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1396\/1676","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1396\/1677","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1396\/1676","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T03:23:10Z","timestamp":1755228190000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/1396"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,12,5]]},"references-count":0,"journal-issue":{"issue":"4950","published-online":{"date-parts":[[2011,12,5]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2011.13314","relation":{},"ISSN":["1424-3997"],"issn-type":[{"value":"1424-3997","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,12,5]]}}}
