Abstract  

Twenty-three knees of 21 patients over 40 years of age with discoid lateral menisci were examined by radiography.The mean age of the patients was 59.7 years (range: 40–78 years). No patient had symptoms before the age of 40 and only 12 knees gave symptoms from the lateral compartment, although tears of a discoid lateral meniscus were diagnosed by arthrography in 21 of the 23 knees. Varus inclination occurred more frequently than valgus inclination. Subchondral bone sclerosis was more common in the medial compartment. However, high incidences of marginal osteophytes in the lateral compartment and morphological anomalies (cupping or flattening) of the lateral tibial plateau were revealed by radiography.

Résumé  

Vingt-trois genoux de 21 patients âgés de plus de 40 ans avec des ménisques latéraux disco¬ıdes furent examinés par radiographie. L’âge moyen des patients était de 59.7 ans (40–78 ans). Aucun des patients ne montra de symptômes avant l’âge de 40 ans et seulement 12 genoux devinrent symptomatiques dans le compartiment latéral, bien qu’un déchirement du ménisque latéral disco¬ıde fut remarqué par arthrographie sur 21 des 23 genoux. Un varus fut observée plus fréquemment qu’un valgus. Une ostéosclérose sous-chondrale fut remarquée plus souvent dans le compartiment médial. D’autre part, des incidences élevées d’ostéophytes marginales dans le compartiment latéral ainsi que des anomalies morphologiques (bombement ou aplatissement) du le plateau tibial latéral furent aussi signalées par radiographie.
