目的本研究的目的是明确内侧髌股韧带（MPFL）髌骨侧的插入部位。方法本研究共使用35个不成对的人体尸体膝盖。识别 MPFL 后，标记 MPFL 髌骨侧的插入部位。创建三维图像，并分析这些插入位点的位置和形态。结果 MPFL 髌骨侧插入位点的形态是一致的。 MPFL 的近端纤维插入股内侧斜肌 (VMO) 深筋膜和股中间肌 (VI) 内侧缘。 MPFL 远端纤维直接插入髌骨内侧缘。 VMO、VI 和髌骨的插入长度分别为 26.7 ± 5.0、28.5 ± 4.4 和 18.5 ± 4.4 mm。髌骨上极至MPFL上缘的垂直距离与髌骨总高度的比率为12±4.4%。在远端边缘，率为58±9.6%。结论MPFL髌骨侧的插入部位是一致的。插入 VMO 和 VI 的 MPFL 明显长于插入髌骨的 MPFL。本研究的临床意义在于提高对 MPFL 髌骨侧插入部位的解剖结构和髌骨脱位病理生理学的理解。
PurposeThe purpose of this study was to clarify the insertion sites on the patellar side of the medial patellofemoral ligament (MPFL).MethodsA total of 35 nonpaired human cadaveric knees were used in this study. After identification of the MPFL, the insertion sites on the patellar side of the MPFL were marked. Three-dimensional images were created, and the location and morphology of these insertion sites were analysed.ResultsThe morphology of the insertion sites on the patellar side of the MPFL was consistent. The proximal fibres of the MPFL were inserted to the deep fascia of the vastus medialis obliquus (VMO) and medial margin of the vastus intermedius (VI). The distal fibres of the MPFL were inserted to the medial margin of the patella directly. The insertion lengths of the VMO, VI, and patella were 26.7 ± 5.0, 28.5 ± 4.4, and 18.5 ± 4.4 mm, respectively. The rate of the vertical distance from the superior pole of the patella to the superior edge of the MPFL in relation to the total patellar height was 12 ± 4.4 %. At the distal edge, the rate was 58 ± 9.6 %.ConclusionThe insertion sites on the patellar side of the MPFL were consistent. The MPFL inserted into the VMO and VI was significantly longer than into the patella. The clinical relevance of this study is to improve understanding of the anatomy of the insertion sites on the patellar side of the MPFL and the pathophysiology of patellar dislocation.
