[The sulcus angle of the femoral trochlea: ultrasonographic evaluation].
The sulcus angle of femoral trochlea is particularly important to evaluate the femoro-patellar joint. Our study was aimed at studying the normal trochlea, and especially the sulcus angle, with US. The right knees of 11 normal subjects were examined with US and Computed Tomography (CT) on the same section planes. The US measurements of the sulcus angle were correlated with CT results, which were considered the gold standard. The US and CT data were compared and a direct correlation was found (r = 0.832). The intraobserver difference in US measurements was r = 0.943. The mean sulcus angle value was 132 degrees, in agreement with literature data. We conclude that the US measurements of the sulcus angle are reproducible and as sensitive as CT.
