Patellofemoral instability is a painful and often recurring disorder with many negative long-term consequences. After a period of failed nonoperative management, surgical intervention has been used to reduce the incidence of patellar subluxation and dislocations. Medial patellofemoral ligament (MPFL) reconstruction successfully addresses patellofemoral instability by restoring the deficient primary medial patellar soft tissue restraint. When planning MPFL reconstruction for instability, it is imperative to consider the patient's unique anatomy including the tibial tuberosity-trochlear groove (TT-TG) distance, trochlear dysplasia, and patella alta. Additionally, it is important to individualize surgical treatment in the skeletally immature, hypermobile, and athletic populations.
髌股关节不稳定是一种疼痛且常复发的病症，会带来许多负面的长期后果。经过一段时间的非手术治疗失败后，手术干预已被用于降低髌骨半脱位和脱位的发生率。内侧髌股韧带（MPFL）重建通过恢复缺失的内侧髌股主要软组织约束，成功解决了髌股关节不稳定问题。在计划针对不稳定的MPFL重建时，必须考虑患者独特的解剖结构，包括胫骨结节-滑车沟（TT-TG）距离、滑车发育不良和高位髌骨。此外，对于骨骼未成熟、活动过度和运动员人群，个体化手术治疗也很重要。
