The role of arthrography in the diagnosis of meniscal tears

The authors discuss the value of arthrography as a supplement to arthroscopy in the diagnosis of meniscal tears. Arthrography is superior to arthroscopy in its ability to detect lesions of the posterior horn of the medial meniscus, which are the most common meniscal tears. Moreover, arthrography can be done on an out-patient basis and at low cost. In any case, the best screening remains thorough clinical examination supplemented, if necessary, by imaging studies.
