股直肌腱自体移植物联合重建内侧髌股韧带与内侧股四头肌腱-股骨韧带
简介
该技术笔记介绍了一种使用股直肌腱自体移植物进行内侧髌股韧带（MPFL）与内侧股四头肌腱-股骨韧带（MQTFL）联合V形重建的新术式。该方法通过更精确地复制内侧髌股复合体的解剖结构，旨在恢复生理性稳定，同时降低髌骨骨折风险，尤其适用于骨骼未成熟的高复发风险髌股不稳患者。
英文摘要
Patellofemoral instability remains a challenging condition, especially in skeletally immature patients, who are at increased risk of recurrence. The medial patellofemoral ligament has historically been the focus of surgical reconstruction; however, recent anatomic studies have also highlighted the medial quadriceps tendon-femoral ligament as part of the medial patellofemoral complex, a key stabilizer during early knee flexion. Recognition of the medial patellofemoral complex has prompted a shift toward combined reconstruction techniques that more accurately replicate native anatomy. The rectus femoris tendon autograft, recently applied in anterior cruciate ligament surgery, offers unique advantages owing to its preserved patellar attachment. In this Technical Note, we describe an anatomic V-shaped reconstruction of the medial patellofemoral complex, combining both medial patellofemoral ligament and the medial quadriceps tendon-femoral ligament with a rectus femoris autograft, providing a biomechanically rational approach that restores physiologic stability while minimizing the risk of patellar fracture.
