Our understanding of the medial patellofemoral complex anatomy has evolved significantly over the past several decades, and this has informed our current surgical approach to management of lateral patellar instability. Medial patellofemoral ligament reconstruction remains the gold standard for decreasing the risk of secondary patellar dislocation and returning patients to active physical function. However, concerns about isometry, overconstraint, secondary arthrosis, and surgical-site morbidity remain with femoral socket fixation, particularly when patella alta, rotational malalignment, or hypermobility is present. Medial patellofemoral ligament reconstruction with soft-tissue fixation, on either the patellar or femoral side, may mitigate some of these risks by offering a more dynamic checkrein to lateral translation. However, longer-term studies are required to determine comparative efficacy with varying surgical techniques, and the ideal graft tension and degree of knee flexion during fixation have not yet been determined.
过去几十年来,我们对内侧髌股复合解剖结构的理解有了显著的进展,这也为我们目前治疗外侧髌股不稳的手术方法提供了信息。内侧髌股韧带重建仍然是降低复发性髌骨脱位风险并使患者恢复积极的身体功能的金标准。然而,对于股骨窝固定,仍然存在等距性、过度约束、继发关节炎和手术部位发病率的担忧,特别是在存在高位髌骨、旋转对线不良或过度活动时。内侧髌股韧带重建采用软组织固定,无论是在髌骨侧还是股骨侧,通过提供更动态的外侧平移止动装置,可能会降低一些风险。然而,还需要进行更长期的研究来确定不同手术技术的比较效果,并且尚未确定理想的移植物张力和固定时膝关节的屈曲程度。
