Objective To explore the clinical application and practical significance of axial patellar radiography in different positions. Methods According to the actual situation of knee joint injury, the appropriate patellar axial position was selected for X-ray photography, and the image quality of different patellar axial position was compared to analyze the diagnosis results. Results The image quality of conventional prone patella axial position was excellent 72.32% and good 20.54%. The image quality of other special patellar axial position accounted for 75% of excellent and 20.59% of good. Conclusion The X-ray image quality of other special position patella axial position is no different from that of conventional patella axial position, which can provide excellent image information and improve the diagnostic accuracy. Moreover, the special position is consistent with the anatomical structure and movement rule of the knee joint and patella, and the patient can maintain a relatively comfortable position. It is recommended that the prone position be promoted as a routine position for patella examination.
