Patellar tendon ruptures are infrequent but disabling injuries. Surgical treatment is the gold standard to obtain good outcomes. Failure of primary repair is a catastrophic complication. The literature regarding patellar tendon re-ruptures is very limited. The purpose of the current study was to evaluate the outcomes of a series of patients who underwent revision surgery for re-rupture of the primary patellar tendon repair.
All patients with patellar tendon re-rupture surgically intervened in our center between 2019 and 2023 were retrospectively reviewed. Patient characteristics, surgical technique, functional and radiological outcomes, and complications were recorded.
Five patients with patellar tendon re-rupture were included, all of whom were male. The mean follow-up period was 30 months. The average age was 54.4 years. Patellar tendon reconstruction was performed in four cases using allografts and in one case using an autograft. The average Lysholm and Kujala scores were 88.8 and 86.8, respectively, while the mean Insall-Salvati and Caton-Deschamps indices were 1.07 at the end of the follow-up. No cases of re-rupture of the reconstructed patellar tendon were observed.
In this case series of patients with patellar tendon re-rupture, revision surgery with reconstruction using autograft or allograft is presented as a valid alternative, with good functional and radiological outcomes at medium-term follow-up.
Case Series Study (Level IV).
髌腱断裂虽不常见，但却是致残性损伤。手术治疗是获得良好疗效的金标准。一期修复失败是一种灾难性并发症。关于髌腱再次断裂的文献非常有限。本研究的目的是评估一系列因一期髌腱修复再次断裂而接受翻修手术的患者的治疗效果。
回顾性分析2019年至2023年在本中心接受手术干预的所有髌腱再次断裂患者。记录患者特征、手术技术、功能和影像学结果以及并发症。
纳入5例髌腱再次断裂患者，均为男性。平均随访时间为30个月。平均年龄为54.4岁。4例采用同种异体移植物进行髌腱重建，1例采用自体移植物。随访结束时，Lysholm和Kujala评分的平均值分别为88.8和86.8，Insall-Salvati和Caton-Deschamps指数的平均值为1.07。未观察到重建髌腱再次断裂的病例。
在这个髌腱再次断裂患者的病例系列中，采用自体或同种异体移植物重建的翻修手术是一种有效的选择，在中期随访中具有良好的功能和影像学结果。
