सार

The diagnostic evaluation of internal derangements within the complex biomechanical architecture of the knee joint demands precise imaging modalities to dictate orthopedic interventions and mitigate chronic arthropathies. This prospective, double-blinded investigation rigorously quantifies the comparative diagnostic accuracy of high-resolution ultrasonography and high-field magnetic resonance imaging in detecting specific soft tissue pathologies, utilizing surgical arthroscopy as the definitive reference standard. A highly controlled clinical cohort of 210 patients presenting with acute and subacute knee trauma underwent sequential sonographic and magnetic resonance evaluations immediately prior to scheduled arthroscopic surgery. Diagnostic parameters, encompassing sensitivity, specificity, positive predictive value, and negative predictive value, were strictly calculated for the central cruciate ligaments, fibrocartilaginous menisci, and peripheral collateral ligament complexes. Magnetic resonance imaging demonstrated overwhelming statistical superiority in the assessment of deep intra-articular structures, achieving an exceptional sensitivity of 95.4% for medial meniscus tears and 97.2% for anterior cruciate ligament ruptures. High-resolution ultrasonography exhibited severe biophysical limitations in evaluating the central pivot and deep meniscal roots due to dense osseous acoustic shadowing. Sonography did, conversely, provide exceptional diagnostic utility for superficial extra-articular structures, registering a 93.8% sensitivity and 96.5% specificity for medial collateral ligament injuries. The sonographic evaluation offered unique dynamic, real-time kinematic assessment capabilities that frequently clarified ambiguous grade II collateral sprains which static magnetic resonance sequences failed to differentiate effectively. The comprehensive statistical synthesis dictates that while magnetic resonance imaging remains the unequivocal gold standard for complete intra-articular mapping, high-resolution ultrasonography serves as a highly effective, cost-efficient initial triage instrument for superficial ligamentous and tendinous lesions. Integrating a sequential, anatomically targeted imaging algorithm optimizes resource allocation within radiological departments while accelerating clinical decision-making.
