摘要：

背景：高位髌骨现在被认为是引起青年人非外伤性前膝痛、髌股关节不稳定、Osgood-Schlatter骨突炎、髌骨软骨软化症的首要原因，因而如何进行早期诊断显得尤为重要。
目的：就高位髌骨的影像学诊断方法的研究进展进行综述。
方法：由第一作者应用计算机检索PubMed数据库1971-01/2011-11有关高位髌骨的相关研究，检索词为“patella alta，diagnosis，radiologic imaging techniques”，排除重复性研究，共保留38篇文献进行综述。
结果与结论：目前常规X射线片是高位髌骨最简便、最常用的诊断方法，但是敏感性不如CT。尽管CT在诊断髌骨位置上具有常规X射线片不可比拟的优势，却不能提供更多的有效信息，考虑到较高的辐射剂量，CT只能作为常规X射线片的替代检查方法。而MRI检查无需暴露于射线中，能对软骨面磨损及骨髓的水肿情况进行准确地显像与描述，可能会更有效地发现少数早期病例，然而受制于高昂的经济成本及时间成本，因此不同地区的骨科医师可依据不同患者灵活多变地选择高位髌骨的影像学诊断方法。

Abstract:

BACKGROUND: Patella alta is considered as the primary reason for pain of anterior knee, unstability of patellofemoral joint, Osgood-Schlatter apophysitis and chondromalacia patellae, so it is important to perform early diagnosis.
OBJECTIVE: To summarize the research advances of the radiologic imaging techniques in diagnosis of patella alta.
METHODS: A computer-based search of PubMed database was undertaken by the first author to identify the articles related to the research on patella alta between January 1971 and November 2011, with the key words of “patella alta, diagnosis, radiologic imaging techniques”. Repetitive studies were excluded, totally 38 articles were reviewed.
RESULTS AND CONCLUSION: To date, X-ray is the most convenient and most commonly used diagnostic method of patella alta, but the sensitivity is lower than CT. Although CT has great advantage than X-ray in identifying the position of patella alta, it cannot provide more effective information. Considering the high radiation dose, CT can only be used as the substitute exam method of X-ray. But magnetic resonance imaging can show accurate imaging and description on the cartilage surface wear and bone marrow edema without exposure to radiation, it may be more effective in finding early cases though it has high economic cost and time cost. Thus, the osteopathic physicians in different regions should take flexible choice in diagnostic imaging method according to different patients.
