Patellar instability is a common knee disorder encountered in young athletes. Patients with normal osseous anatomy and mechanical alignment of the lower extremity are candidates for soft-tissue reconstructive procedures. In skeletally immature patients, surgical techniques that address patellar instability must avoid disruption of open physes and therefore must rely on soft-tissue techniques. Biomechanical research demonstrates that the medial patellofemoral ligament is the primary soft-tissue restraint to lateral subluxation of the patella, and the medial patellotibial ligament is an important secondary stabilizer. We present a novel physeal-sparing surgical technique that anatomically reconstructs both the medial patellofemoral and medial patellotibial ligaments using semitendinosus autograft.
髌骨不稳定是年轻运动员中常见的膝关节疾病。具有正常下肢骨骼解剖结构和力学对线的患者适合进行软组织重建手术。在骨骼未成熟的患者中，治疗髌骨不稳定的手术技术必须避免破坏开放的骨骺，因此必须依赖软组织技术。生物力学研究表明，髌股内侧韧带是髌骨向外侧半脱位的主要软组织约束，而髌胫内侧韧带是重要的次要稳定器。我们提出了一种新颖的保留骨骺的手术技术，该技术使用半腱肌自体移植物在解剖学上重建髌股内侧韧带和髌胫内侧韧带。
