Patellar instability is a common complaint after traumatic dislocation of the patella. Traumatic dislocation always leads to tearing of the medial patellofemoral ligament (MPFL). Treatment consists of recovery from the traumatic injury, followed by reconditioning and physical therapy to strengthen the dynamic stabilizers of the patella. In patients with recurrent instability, detailed evaluation of the cause is required to determine the needed interventions. In patients with an incompetent MPFL and recurrent instability, reconstruction is indicated, along with other procedures to address other contributing factors. This article details our technique for MPFL reconstruction using semitendinosus autograft, which can be performed alone or in concert with other realignment procedures.
髌骨不稳是髌骨外伤性脱位后的常见症状。外伤性脱位总会导致髌股内侧韧带（MPFL）撕裂。治疗包括从外伤中恢复，随后进行康复训练和物理治疗，以加强髌骨的动态稳定结构。对于复发性不稳的患者，需要详细评估病因以确定所需的干预措施。对于MPFL功能不全且复发性不稳的患者，除了采取其他措施解决其他促成因素外，还需进行重建手术。本文详细介绍了我们使用半腱肌自体移植物进行MPFL重建的技术，该技术可单独进行，也可与其他矫正手术联合进行。
