Diagnosis of knee injuries: comparison of the physical examination and magnetic resonance imaging with the findings from arthroscopy

Meniscal and ligament injuries can be diagnosed through careful physical examination, while requests for MRI are reserved for complex or doubtful cases. PE and MRI used together have high sensitivity for ACL and MM lesions, while for LM lesions the specificity is higher. Level of evidence II - Development of diagnostic criteria on consecutive patients (with universally applied reference "gold" standard).
