A quadriceps tendon rupture is a traumatic injury of the quadriceps insertion on the patella leading to a disruption in the knee extensor mechanism. Diagnosis is usually made clinically with a palpable defect proximal to the superior pole of the patella coupled with the patient's inability to perform a straight leg raise and confirmed on radiographs, ultrasonography, or magnetic resonance imaging scan. When the extensor mechanism is disrupted, operative repair is indicated. Two common techniques have been described for repair: the transosseous) repair and the suture anchor repair, and both have shown good clinical results. Nevertheless, gap formation is always a concern, and there is no consensus if one technique is superior to the other in this matter. We propose a low-cost, tensionable, transosseous anatomic repair that results in a tight construction.
股四头肌肌腱断裂是股四头肌在髌骨上附着处的创伤性损伤，导致膝关节伸肌机制中断。诊断通常通过临床触诊髌骨上极近端的明显缺损以及患者无法进行直腿抬高来做出，并通过X线片、超声或磁共振成像扫描得到证实。当伸肌机制中断时，需进行手术修复。已描述了两种常见的修复技术：经骨修复和缝线锚钉修复，两者均显示出良好的临床效果。然而，间隙形成始终是一个问题，在这方面哪种技术更优尚无共识。我们提出一种低成本、可张紧的经骨解剖修复方法，其可形成紧密结构。
