Several parameters in the anteroposterior and lateral views on the plain roentgenograms were compared between 17 cases of the discoid lateral meniscus and 19 cases of the semilunar lateral meniscus in order to find whether the plain roentgenogram could discriminate between the discoid and semilunar menisci. These parameters wereas follows: the distance between the anterior notches of both femoral condyles, and the posterior inclination of the tibial plateau in the lateral view; the ratio of the lateral femoral condyle to the medial femoral condyle, the ratio of the lateral joint space to the medial femorotibial joint space, and the concavity of the lateral tibial plateau in anteroposterior view. Any significant difference was not found in these parameters. Morphology including articular cartilage and meniscus should be investigated further in regard to the difference of the both types of the meniscus.
