We have analyzed the normal patellar motion during the first 30 degrees of knee flexion by magnetic resonance imaging (MRI). Ten males and 10 females without knee symptoms were examined. The patellar articulation was imaged both sagittaly and axially with the knee flexed 0, 10, 20, and 30 degrees. The axial images were produced through the middle of the patellar articular cartilage. When the knee was in extension compared to 30 degrees flexion, the sulcus angle was greater, the lateral patellofemoral angle was smaller, there was more lateral patellar displacement, the patella tilted more laterally, and the congruence angle was directed more laterally. Differences between males and females were found.
我们通过磁共振成像（MRI）分析了膝关节屈曲最初30度时正常髌骨的运动情况。对10名无膝关节症状的男性和10名女性进行了检查。在膝关节分别屈曲0度、10度、20度和30度时，对髌骨关节进行矢状面和轴位成像。轴位图像通过髌骨关节软骨中部生成。与膝关节屈曲30度时相比，膝关节伸直时，沟角更大，髌股外侧角更小，髌骨向外侧移位更多，髌骨向外侧倾斜更明显，且适合角更偏向外侧。同时发现了男性和女性之间的差异。
