Objective: To determine diagnostic accuracy of magnetic resonance imaging (MRI) in assessment of anterior cruciate ligament injuries of the knee joint, taking arthroscopy as gold standard.
Methodology: This cross-sectional validation study was carried out at Radiology and Orthopedic Departments of Capital Hospital, Islamabad, Pakistan from January 2015 to February 2016. A total of 98 patients with history of knee trauma were included in the study. All were scanned with MRI knee joint followed by arthroscopy. Two consultants including radiologist and orthopaedic surgeon reported the MRI and arthroscopic findings. Data were analysed using SPSS version 16.
Results: Mean age was 31.88±10.35 years. Male to female ratio was 1.9:1. Sensitivity and specificity of MRI to detect anterior cruciate ligament injuries was 91.8% and 91.89%, respectively.
Conclusion: MRI was sensitive, specific and non invasive imaging modality in assessment of anterior cruciate ligament injuries of the knee joint.
Key words: Magnetic resonance imaging, arthroscopy, anterior cruciate ligament injuries, meniscal injuries.
