Patellar duplication is a rare asymptomatic condition. The diagnosis is often made following a traumatic event associated with an injury to the knee extensor mechanism. The treatment is often surgical and consists in removal of the smaller part of the patella with tendon reinsertion. The presence and rupture of an intermediate tendon between the two parts of the patella have not been reported in the modern literature. We present a traumatic rupture of an intermediate tendon in a patient with horizontal patellar duplication. The surgical management consisted of tenorrhaphy protected with a figure-of-eight tension band wire approximating the two parts of the patella. The patient recovered full knee range of motion and quadriceps strength at the last 8-month follow-up.
髌骨重复是一种罕见的无症状病症。诊断通常在与膝伸肌机制损伤相关的创伤事件后作出。治疗通常为手术治疗，包括切除较小部分的髌骨并重新插入肌腱。现代文献中尚未报道髌骨两部分之间中间肌腱的存在及断裂情况。我们报告一例水平髌骨重复患者的中间肌腱创伤性断裂。手术治疗包括用8字形张力带钢丝保护缝合修复来使髌骨两部分靠近。在最后8个月的随访中，患者膝关节活动范围和股四头肌力量完全恢复。
