Ipsilateral injury of more than one component of the knee extensor apparatus is rare. It is mostly associated with previous trauma, surgery, immunosuppression therapy and systemic disease. We present the first documented case of a spontaneous bifocal disruption of the knee extensor apparatus (i.e. floating patella) associated with lymphoedema. This case highlights the importance of considering lymphoedema as another risk factor for rupture of the knee extensor apparatus. It also highlights the importance of assessing all components of the knee extensor apparatus in patients presenting with acute knee injuries.
膝关节伸肌装置多个组成部分的同侧损伤较为罕见。它大多与既往创伤、手术、免疫抑制治疗及全身性疾病有关。我们报告首例有记录的与淋巴水肿相关的膝关节伸肌装置自发性双灶性断裂（即浮动髌骨）病例。该病例凸显了将淋巴水肿视为膝关节伸肌装置断裂的另一风险因素的重要性。它还强调了在急性膝关节损伤患者中评估膝关节伸肌装置所有组成部分的重要性。
