In routine MRI of the knee, less attention frequently is paid to the patellofemoral joint and its surrounding structures than to the menisci and ligaments. This article reviews MRI of common abnormalities of the anterior aspect of the knee. Chondromalacia patellae, pathological softening of the patellar cartilage, can be diagnosed with reasonable accuracy with MRI using standard sequences. Abnormalities of alignment can be assessed grossly on static images, but more sophisticated evaluation of patellofemoral tracking requires the kinematic technique. Other traumatic or overuse injuries involving the extensor mechanism of the knee, such as the quadriceps and patellar tendons, are also reviewed briefly.
在膝关节的常规磁共振成像（MRI）检查中，相较于半月板和韧带，髌股关节及其周围结构常常较少受到关注。本文回顾了膝关节前方常见异常情况的MRI表现。髌骨软化症，即髌骨软骨的病理性软化，使用标准序列的MRI能够以合理的准确性进行诊断。对线异常可在静态图像上大致评估，但对髌股关节轨迹进行更精确的评估则需要采用动态成像技术。其他涉及膝关节伸肌机制的创伤性或过度使用损伤，如股四头肌和髌腱损伤，也将进行简要回顾。
