Objective: To review the influencing factors of medial patellofemoral ligament (MPFL) reconstruction for patellar dislocation.
Methods: The literature of MPFL reconstruction for patellar dislocation at home and abroad in recent years were summarized and analyzed.
Results: The influencing factors such as the location of the femoral insertion point, the tension and the fixed angle of the grafts, the dysplasia of the femoral trochlear before operation, the abnormal tuberositas tibiae-trochlear groove value, the high position of the patellar, and the tilting angle of the patellar, are all the factors affecting the effectiveness of MPLF reconstruction.
Conclusion: During MPFL reconstruction, the surgical techniques and elimination of other factors that caused patellar instability need to be focused in order to reduce the complications and operation failure.
目的: 对内侧髌股韧带（medial patellofemoral ligament，MPFL）重建治疗髌骨脱位的影响因素进行综述。.
方法: 广泛查阅近年国内外 MPFL 重建治疗髌骨脱位的相关文献，并进行总结分析。.
结果: 重建术中移植物股骨止点定位、移植物张力及固定角度、术前膝关节股骨滑车发育不良、胫骨结节-股骨滑车沟值异常、高位髌骨及髌骨倾斜角等因素，均是影响手术疗效的因素。.
结论: MPFL 重建治疗髌骨脱位需注意手术技巧及消除其他导致髌骨不稳定的因素，以减少并发症及手术失败。.
