Summary
Direct methods were used to determine the distribution of injuries to the menisci in formalin fixed knee joints, rotated under physiological pressures when extended and at different degrees of flexion. The position of the joint during rotation rather than the direction of rotation determined the distribution of injury between the menisci, whereas both direction of rotation and joint position determined the position of major types of lesion within the meniscus. Support is given for the view that the incidence of injury to the lateral meniscus is higher than generally accepted.
Résumé
Une expérimentation cadavérique a été réalisée sur des genoux fixés par le formol, dans le but d'étudier le déterminisme des lésions méniscales traumatiques. Des forces de rotation ont été exercées, sous pression physiologique, sur des genoux en extension complète, puis à des degrés divers de flexion. La position du genou pendant la rotation, plus que le sens de cette rotation, conditionne l'atteinte de l'un des deux ménisques, tandis que c'est à la fois le sens de la rotation et la position du genou qui déterminent le type de la lésion méniscale. Ces constatations permettent de penser que le ménisque externe est plus fréquemment atteint qu'il n'est habituel de le dire.
