Intrasubstance patellar tendon ruptures are an uncommon injury that can have devastating long-term effects for patients. Operative intervention to repair the ruptured tendon is the gold standard treatment for these injuries and can be performed using a variety of techniques. Unlike the more common patellar tendon ruptures at the level of the patella, repairs of intrasubstance ruptures are often challenging because of the poor quality of the remaining tendon fibers. Tendon repair with augmentation via bio-inductive implants has gained popularity in upper extremity literature, as it has demonstrated improved tendon strength and patient outcomes. However, there remains a sparsity of reports regarding tendon augmentation in the lower extremity literature. Here, we describe repair of an intrasubstance patellar tendon rupture using a modified SpeedBridge repair and augmentation with a bio-inductive implant.
髌腱实质内断裂是一种罕见的损伤，可对患者产生严重的长期影响。手术干预修复断裂的肌腱是这些损伤的金标准治疗方法，可采用多种技术进行。与更常见的髌骨水平髌腱断裂不同，由于剩余肌腱纤维质量差，髌腱实质内断裂的修复通常具有挑战性。通过生物诱导植入物进行增强的肌腱修复在上肢文献中越来越受欢迎，因为它已证明可提高肌腱强度和患者预后。然而，关于下肢文献中肌腱增强的报道仍然很少。在此，我们描述了使用改良的SpeedBridge修复和生物诱导植入物增强来修复髌腱实质内断裂。
