[Diagnostic correlation between magnetic resonance imaging and arthroscopic findings in anterior cruciate ligament injuries].

Abstract

Purpose of the study: determine the sensitivity and specificity of magnetic resonance imaging in anterior cruciate ligament injuries and associated injuries through arthroscopic findings.

Material and methods: this is a retrospective, longitudinal, cross-sectional study in 96 patients with ACL injuries were included and who underwent arthroscopic surgery; arthroscopic findings were compared with diagnostic magnetic resonance images as well as associated lesions.

Results: for ACL lesions the following data were found in relation to the agreement by MRI and arthroscopic findings; 93.68% sensitivity, 100% specificity. Negative predictor value of 14.28% and a positive predictor value of 100%.

Conclusion: MRI is an accurate and non-invasive imaging modality for the evaluation of knee injuries, the diagnostic association is considerably high.
