Objective To evaluate the diagnostic value of MR imaging for anterior cruciate ligament. Methods We searched PubMed, EMBASE, CBM, CSJD and CJFD to find all diagnostic tests about MR imaging in anterior cruciate ligament. QUADAS items were used to evaluate the quality of the included studies. We used Meta-disc software for data collection, and sensitivity, specificity and SROC curves were calculated to assess the diagnostic value of individual diagnostic tests. Results Twenty-nine studies met the eligibility criteria and were included. Compared with arthroscope, the summary values of sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and SROC curve of MR imaging were 93%, 93%, 9.85, 126.39, and 0.971 4, respectively. Conclusion MR imaging can be regarded as an effective and feasible method for ACL tears diagnosis and screening clinically, based on the results of this systematic review.
