title: Arthroscopy and arthrography of the knee: a comparison study.
abstract: Between 1975 and 1978, over 200 knee arthroscopies were performed at the Emory University Hospitals; the findings were totally correct in 91%. During the same period, arthrograms were performed on 79 different patients, 39 of whom had confirming arthrotomies. The arthrograms were totally correct in 38%. Fifteen totally incorrect arthrograms were reviewed without knowledge of the operative findings; 12 were considered by the radiologist to be technically acceptable for review. Of these, five correlated partially, but none completely, with findings at arthrotomy. We discuss the difficulty in arthrographic reading of lateral meniscus tears, anterior cruciate tears, and osteochondral loose bodies. We conclude that, although arthroscopy and arthrography can be complementary, arthrography must be used only with the best equipment and technic by a motivated, experienced, and enthusiastic radiologist.
