investigations

Last reviewed 01/2018

Investigations which are of use for meniscal tears include:

  • MRI scanning is replacing arthrography as the first-line investigation
    • is the gold standard investigation method and is highly accurate in diagnosing meniscal and anterior cruciate ligament (ACL) tears
    • most appropriate screening tool before arthroscopy
    • the sensitivity and specificity of MRI for
      • medial meniscal tears - 93% and 88% respectively
      • lateral meniscal tears - 79% and 95% respectively (1)
  • arthroscopy: definite diagnosis
  • plain radiographs
    • useful in differentials e.g. - excluding bony pathologies and to assess the concomitant presence of arthropatic changes (1)
