Patellar tendon rerupture is a relatively uncommon condition that severely compromises the function of the extensor mechanism of the knee. Few cases described in the literature does not show a unique mode of treatment for this type of lesion. We report the case of a young athlete with traumatic patellar tendon rerupture. The first rupture was treated with the use of Statak anchors. Following a second rerupture incident as a result of a sporting accodent, the tendon was reconstructed with the use of an autologous graft tendon of semitendinosus and biological augmentation with gracilis tendon. For both tendons the distal insertion part was preserved to facilitate the healing process. The treatment was completed with the application of a neutralization cerclage wire and with local injection of plateket reach plasma (PRP). At 12 months follow up, a full recovery of the structure and function of the extensor mechanism was observed and the patient was able to resume normal sports competitive activity.
髌腱再断裂是一种相对少见的疾病，严重影响膝关节伸肌机制的功能。文献中描述的少数病例并未显示出对此类损伤的独特治疗模式。我们报告了 1 例年轻运动员外伤性髌腱再断裂的病例。首次断裂采用 Statak 锚钉治疗。由于运动损伤导致第二次再断裂后，使用自体半腱肌移植物和生物增强性 gracilis 肌腱进行重建。对于这两个肌腱，都保留了远端插入部分以促进愈合过程。治疗完成后，应用中和环状钢丝，并局部注射血小板浓缩生长因子（PRP）。12 个月随访时，观察到伸肌机制的结构和功能完全恢复，患者能够恢复正常的体育竞技活动。
