From: Diagnosis of ACL and meniscal injuries: MR imaging of knee flexion versus extension compared to arthroscopy

 

Intact medial meniscus (specificity)

Medial meniscus tear (sensitivity)

Arthroscopy (n = 29)

  1. Diagnosis of these injuries by MRI was compared to arthroscopy. The number of correctly diagnosed healthy menisci (specificity) and pathological meniscal injuries (sensitivity) are presented.
