Abstract

The soft tissues of the knee can be injured, swollen, or impinged due to the different movements and stress to which they are subjected. This can occur due to repetitive or strenuous activity, or due to anatomical predisposition during routine activities. Generally, patients present vague discomfort, without specific signs on physical examination. Magnetic resonance imaging (MRI) plays a fundamental role in the study of impingement and friction syndromes in the knee, given its sensitivity in detec-ting inflammatory changes and its high tissue contrast, with the adipose tissue around the knee being the main affected. The friction and impingement syndromes around the knee can be classified by region (anterior, medial, posterior and lateral) and origin (intra or extracapsular). Signal alterations in MRI are usually similar in different conditions when adipose or connective tissue is altered, varying the anatomical site and the structures that surround it. The anatomical landmarks that allow its ade-quate characterization and diagnosis are described. A review of prepatellar friction syndrome, infrapatellar, suprapatellar and prefemoral adipose tissue impingement, superior and medial patellar plica impingement, posteromedial friction syndrome, osteo-meniscal impingement, pericruciate impingement, popliteal tendon and ilio-tibial band friction syndrome are included.
膝关节捏伤和摩擦综合征:磁共振成像中的象形图综述
由于不同的运动和压力,膝关节的软组织可能会受伤、肿胀或撞击。这可能是由于重复或剧烈的活动,或由于日常活动中的解剖易感性。患者一般表现为模糊的不适,体格检查无明显体征。磁共振成像(MRI)由于其检测炎症变化的敏感性和高组织对比度,在膝关节撞击和摩擦综合征的研究中起着基础作用,而膝关节周围的脂肪组织是主要受影响的组织。膝关节周围的摩擦和撞击综合征可按区域(前、内、后、外侧)和起源(囊内或囊外)分类。当脂肪或结缔组织发生改变时,MRI的信号改变在不同情况下通常是相似的,改变了解剖部位及其周围的结构。解剖标志,允许其充分表征和诊断描述。本文综述了髌前摩擦综合征、髌下、髌上和股前脂肪组织撞击、髌上和内侧皱襞撞击、内侧后摩擦综合征、骨-半月板撞击、交叉韧带撞击、腘肌腱和髂-胫束摩擦综合征。
