目的对髌骨外侧高压综合征的 影像学诊断及最新进展进行综述，探讨各 个指标的优点和局限性，为下一步研究 拓宽思路。方法 检索中国知网及Pubmed 数据库，对髌骨外侧高压综合征影像学 诊断方面的文献进行报道，并对不同的 检查方法进行分类讨论。中文检索词为 “髌骨外侧高压综合征、髌骨外侧挤压综 合征、髌股关节紊乱、诊断”，英文检 索词为“excessive lateral pressure syndrome，diagnosis”。结果 髌股外侧 高压综合征的MRI表现主要包括髌骨位置 的改变及运动轨迹异常，髌股关节软骨退 变以及髌骨支持带病变，如有条件行T1ρ 检查，还有可能早于关节镜发现肉眼不可 见的ELPS髌股关节病变。结论 MRI检查对 髌股外侧高压综合征有着重要的诊断价 值，其为无创检查，并且可以早于关节镜 发现病变，还可以评估疗效及预测预后， 可以作为ELPS患者的最佳检查手段。

Objective This review was written in the hope to help with the overall clarification of the research in this field and provide with potential research methods for up-coming researches. Methods In research within CNKI and Pubmed database, and retrieve the database using the keyword 'excessivelateral pressure syndrome，diagnosis' Results MRI findings of the ELPS include high pressure in the patella position and trajectory change of the patellofemoral joint cartilage, and the degeneration of patellar lesions, if T1ρ line inspection can be performed, there may be earlier results than the what arthroscopic may found not visible to the ELPS patellofemoral joint disease. Conclusion MRI examination of the lateral patellofemoral hypertension syndrome has important diagnostic values, which is noninvasive and can be found in early lesions in arthroscopy, but also to assess the efficacy and prognosis, as the best means of checking ELPS patients.
