Quadriceps tendon ruptures are devastating injuries that impair the extensor mechanism of the knee. Complete tears require prompt surgical intervention in order to ensure optimal clinical outcomes. Chronic, neglected ruptures- marked by severe extensor lag, muscular atrophy, and tendon retraction- are difficult to treat. Further, severe patella baja complicates surgical planning. While there is no consensus on optimal treatment for these injuries, many different techniques have been proposed. Unlike many of these approaches, our technique focuses on restoration of patellar height via patellar tendon lengthening. Once patellar height is restored, quadriceps tendon repair can be performed using the native quadriceps tendon. Both the patellar tendon lengthening and the quadriceps tendon repair are augmented with bioinductive implants to ensure optimal healing environments, enabling us to reestablish native extensor mechanism function.
股四头肌肌腱断裂是严重损伤，会损害膝关节的伸肌机制。完全撕裂需要及时进行手术干预，以确保获得最佳临床效果。慢性、被忽视的断裂（其特征为严重伸肌滞后、肌肉萎缩和肌腱回缩）难以治疗。此外，严重的低位髌骨会使手术规划复杂化。虽然对于这些损伤的最佳治疗方法尚无共识，但已提出了许多不同的技术。与许多这些方法不同，我们的技术侧重于通过髌腱延长来恢复髌骨高度。一旦恢复髌骨高度，就可以使用天然股四头肌肌腱进行股四头肌肌腱修复。髌腱延长和股四头肌肌腱修复均使用生物诱导植入物增强，以确保最佳愈合环境，使我们能够重建天然伸肌机制功能。
