Posterior ankle impingement syndrome (PAIS) is a common and debilitating condition, commonly affecting people who participate in activities that involve repetitive ankle plantarflexion. The relationship between clinical and imaging findings in PAIS has not been established.
To investigate the relationship between clinical and imaging features in PAIS by reviewing the literature comparing symptomatic patients to asymptomatic controls.
A systematic literature search was performed to identify all English-language articles that compared imaging features in patients diagnosed with PAIS to imaging in an asymptomatic control group.
A total of 8394 articles were evaluated by title and abstract, and 156 articles were read in full text. No articles compared imaging findings to an asymptomatic control group, thus no articles met the inclusion criteria.
This systematic review found no published research that compared the imaging findings of people diagnosed with PAIS to asymptomatic people. Until this information is available, imaging features in people with posterior ankle impingement should be interpreted with caution.
后踝撞击综合征（PAIS）是一种常见且使人虚弱的疾病，通常影响那些从事涉及反复踝关节跖屈活动的人。PAIS 的临床和影像学表现之间的关系尚未确定。
通过回顾比较症状性患者和无症状对照组的文献，探讨 PAIS 的临床和影像学特征之间的关系。
进行了系统的文献检索，以确定所有比较 PAIS 患者影像学特征与无症状对照组影像学特征的英文文献。
通过标题和摘要评估了 8394 篇文章，然后全文阅读了 156 篇文章。没有文章将影像学发现与无症状对照组进行比较，因此没有文章符合纳入标准。
本系统评价未发现将诊断为 PAIS 的患者的影像学表现与无症状人群进行比较的研究。在获得这些信息之前，应谨慎解释患有后踝撞击症的人的影像学特征。
