Abstract
Background
Cruciate ligament tears, particularly of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL), are common knee injuries requiring accurate diagnosis for optimal management. Magnetic Resonance Imaging (MRI) is the gold standard for non-invasive evaluation, but its diagnostic performance for partial tears and associated injuries warrants further validation.
Objectives
Assess the diagnostic accuracy of MRI (1.5-Tesla) in detecting complete and partial ACL/PCL tears, using arthroscopy as the reference standard.
Methods
A prospective cross-sectional study was conducted on 60 patients with clinically suspected cruciate ligament injuries. MRI findings (T1, T2-weighted, and PD sequences) were independently analyzed by two blinded radiologists and correlated with arthroscopic results. Statistical analysis included sensitivity, specificity, PPV and NPV
Results
MRI demonstrated high accuracy for complete ACL tears (sensitivity: 94%, specificity: 92%) and PCL tears (sensitivity: 96%, specificity: 94%). Partial tears showed lower sensitivity (85%).
Conclusion
MRI is a highly reliable tool for diagnosing complete cruciate ligament tears, with excellent correlation to arthroscopy. However, partial tears remain a diagnostic challenge. The frequent detection of associated injuries underscores MRI’s role in comprehensive knee assessment. Future studies should explore advanced MRI techniques (e.g., 3-Tesla) to improve partial tear diagnosis.
