Abstract
 INTRODUCTION: The most frequently injured ligament in the knee is the ACL, and this condition cannot be cured. The knee frequently suffers joint injuries since it is involved in the movement. The latest "gold standard" for the diagnosis of ACL tears is arthroscopy, which has a 100% accuracy rate. However, arthroscopy is an intrusive procedure that carries some complications for the patients. As a result, a lot of patients are hesitant to use this procedure while getting a diagnosis. Hence, this study aims to compare the diagnostic accuracy between MRI and knee arthroscopy, to study the advantages of MRI compared to knee arthroscopy and to assess the role of different MRI sequences in diagnosing ACL tears. MATERIALS & METHODS: A Systematic Literature Reviews was conducted by searching reliable database. This study conducted by using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. QUADAS-2 and its signalling questions was utilized to evaluate risk of bias. RESULTS: 17 articles are selected for this review that being access through the PubMed. The diagnostic accuracy of the MRI is significantly high in detecting ACL tears with the sensitivity within the range of 81% to 98.60%, the specificity collected within 79% to 100%, the PPV range between 80.55% to 100%, NPV within the range of 74.50% to 100% and AUC value of more than 0.9. The risk of bias and applicability concerns of each study were evaluated. CONCLUSION: The diagnosis of ACL injury using MRI has high diagnostic accuracy but knee arthroscopy remains as the gold standard in evaluating ACL tears. MRI has established as the non-invasive, radiation free, have great cost effectiveness, quick and no risk of complications. Nevertheless, no explicit outcome of what the best sequences for ACL tears detection but T2-weighted images are commonly used to visualise ACL. Additional sequences can be used such as volume sequences of DESS and FLASH.
