Summary
In 150 normal subjects the distance (P) between the upper and lower limits of the articular surface of the patella, and the shortest distance (T) between this same lower limit and the tibial plateau, were measured in standard lateral views of the knee in about 30° of flexion. The limits of confidence of the T/P ratio are shown in the Table. The 5% upper limit of normality of this ratio is 1.11 (one-sided). This method of determining the position of the patella is accurate and more simple than those previously described.
Résumé
On a mesuré chez 150 sujets normaux, sur des profils standard du genou à 30° de flexion environ, la distance (P) entre les limites supérieure et inférieure de la surface articulaire de la rotule et la plus courte distance (T) entre cette même limite inférieure et le plateau tibial. Les valeurs du rapport T/P sont notées sur la tableau. La valeur de ce rapport, 5% supérieure à la normale est de 1.11. Cette méthode de mesure de la situation de la rotule est précise et plus simple que celles qui ont été précédemment décrites.
