Evaluation Of Application Value Of Clinical Tests And MRI In The Diagnosing Meniscus Injury

Objective:To compare the reliability and value of clinical tests and MRI in diagnosisof meniscus injury in order to increase the diagnostic rate.Methods:A prospective studywas done on the reliability and value of clinical tests and MRI in diagnosis of meniscusinjury.From January2011to January2013,this group included109patients meeting thecriteria,a total of122knees,244meniscus.All the knee is test using the clinical commonly,MRI and arthroscopic diagnosis and treatment.The arthroscopic diagnosis was thestandard for damage campared the clinical test to MRI diagnosis of meniscus sensitivity,specificity,accuracy and Kappa value.A statistical analysis of chi-square test was donebetween two group and the gold standard.Results:The sensitivity, specificity and accuracyof clinical tests diagnosis of meniscus injury were92%,29%and81%respectively.Therewas not statistically significant difference between arthroscopic diagnosis and clinicaldiagnosis.The sensitivity, specificity and accuracy of MRI diagnosis of meniscus injurywere97%,10%and82%respectively.There was statistically significant differencebetween arthroscopic diagnosis and clinical diagnosis.The sensitivity,specificity andaccuracy of MRI diagnosis of meniscus tears were82%,93%and89%respectively.Thedifference between arthroscopic and MRI diagnosis of meniscus tears had no statisticallysignificance and can be used as an important examination before knee arthroscopy.Conclusion:Clinical texts and MRI diagnosis of meniscus injury of high sensitivity,andshould be closely combined with the diagnosis of MRI;a high coincidence rate of thediagnosis of meniscus tears, for noninvasive diagnosis, and reduce the operation treatmentis not necessary;to guide the clinical treatment better.
