In this article we provide an overview of impingement syndromes of the lower limb. At the level of the hip, femoroacetabular and ischiofemoral impingement are recognised. At the level of the knee, we discuss Hoffa's fat pad impingement, suprapatellar fat pad impingement, pericruciate impingement, and iliotibial band syndrome. The impingement syndromes associated with anterior cruciate ligament (ACL) repair and intercondylar osteophytes are also illustrated. Most impingement syndromes are described at the level of the ankle. These include, anterior, anterolateral, posterior, anteromedial, posterior, and posterolateral impingement. For these conditions, we describe the best technique and expected imaging findings. It should be kept in mind that many of these findings have been observed in the asymptomatic population. Impingement is essentially a clinical diagnosis and imaging findings should be considered as supportive elements for this clinical diagnosis.
在本文中，我们概述了下肢撞击综合征。在髋关节层面，股骨髋臼撞击症和坐骨股骨撞击症已得到认可。在膝关节层面，我们讨论了霍法脂肪垫撞击症、髌上脂肪垫撞击症、交叉韧带周围撞击症和髂胫束综合征。还阐述了与前交叉韧带（ACL）修复和髁间骨赘相关的撞击综合征。大多数撞击综合征在踝关节层面进行描述。这些包括前侧、前外侧、后侧、前内侧、后侧和后外侧撞击症。对于这些病症，我们描述了最佳技术和预期的影像学表现。应当记住，许多这些表现已在无症状人群中观察到。撞击本质上是一种临床诊断，影像学表现应被视为支持这一临床诊断的要素。
