Abstract

Objective: To investigate the morphometric parameters of the patellofemoral joint in Vietnamese adults according to gender and age. Subjects and Methods: A total of 64 individuals undergoing computed tomography (CT) scans of the knee joint, with or without contrast enhancement, were enrolled. Morphological measurements of the patellofemoral joint were obtained. Results and Conclusion: The mean values (± standard deviation) of five key patellofemoral morphometric indices were as follows: Sulcus Angle (SA): 132.81 ± 4.66°, Patellar Tilt Angle (PTA): 11.12 ± 1.52°, Tibial Tubercle–Trochlear Groove distance (TT–TG): 12.34 ± 0.90 mm, Trochlear Groove Depth (TGD): 5.93 ± 0.62 mm, and Trochlear Facet Asymmetry (TFA): 59.44 ± 5.78%. Statistically significant gender differences were observed in 3 out of 5 parameters. Female participants exhibited greater trochlear groove depth (TGD) on both sides and higher trochlear facet asymmetry (TFA) on the right knee. Conversely, male participants showed a greater TT-TG distance on the left knee. No statistically significant correlation was found between age and any of the five assessed parameters. Regarding the interrelationship between parameters, a strong inverse correlation was identified between sulcus angle (SA) and trochlear groove depth (TGD). Additionally, weak positive correlations were noted between TT-TG distance and patellar tilt angle (PTA), between TT-TG distance and TGD, and between TGD and TFA.
