sional
computed tomography (3D CT), to standardize the technique, and to show the inter- and intra-observer reliability of
this measurement.
Methods The present study included 62 asymptomatic volunteers (124 knees). 3D CT scanning was performed with each
volunteer in the supine position with 15° of knee flexion, and consistent 3D axial images of the patellofemoral joint were
obtained with alignment in the desired stereographic baseline direction in anterior?posterior, lateral, and axial rotations.
Two independent observers measured patellofemoral alignment parameters, including the sulcus angle, congruence angle,
lateral patellofemoral angle, condyle-patellar angle, and lateral trochlear inclination angle.
Results Based on 3D CT measurement, the mean values of the parameters were 145.9° ± 9.2° for the sulcus angle,
12.6° ± 22.6° for the congruence angle, 9.2° ± 4.6° for the lateral patellofemoral angle, 14.1° ± 6.4° for the condyle-patellar
(lateral facets) angle, ? 8.5° ± 8.4° for condyle-patellar (patellar axis) angle, and 16.5° ± 6.3° for the lateral trochlear inclination
angle. A statistically significant difference was observed between men and women in the sulcus and condyle-patellar
(patellar axis) angles (p = 0.045, 0.011, respectively). All parameters showed excellent inter- and intra-observer reliability.
Conclusion The normal values and ranges for patellofemoral alignment parameters were evaluated using 3D CT. The results
of this study provide reference information that may facilitate diagnosis and treatment planning of patellofemoral disorders
in skeletally mature non-pathologic patients.
