We present a case of an anterior capsular tear of the right knee in a previously healthy, active individual. The patient was a 31-year-old male seen one month after the onset of throbbing anterior right knee pain, which progressed to sharp suprapatellar pain over the next three months. Both dynamic ultrasound (US) and MRI were obtained. Dynamic US revealed a tear of the anterior capsule of the right knee complicated by a suprapatellar effusion communicating into the vastus intermedius fibers of the quadriceps tendon. However, these findings were not evident on MRI. In addition to discussing this unique pathology, we highlight the utility of both standard and dynamic US in establishing diagnoses for capsular pathologies.
我们报告一例既往健康、活动自如的个体出现右膝前囊撕裂的病例。患者为一名31岁男性，在右膝前部搏动性疼痛发作1个月后前来就诊，在接下来的3个月中，疼痛发展为髌上尖锐疼痛。进行了动态超声（US）和磁共振成像（MRI）检查。动态超声显示右膝前囊撕裂，并伴有髌上积液，该积液与股四头肌肌腱的股中间肌纤维相通。然而，这些发现在MRI上并不明显。除了讨论这种独特的病理学情况外，我们还强调了标准超声和动态超声在诊断囊膜病变方面的实用性。
