The purpose of this study was to identify the femoral insertion of the medial patellofemoral ligament (MPFL) and related osseous landmarks.
A total of 31 unpaired human cadaveric knees were studied. The MPFL was identified, and the site of its femoral insertion was marked. Three-dimensional images were created, and the location and morphology of the femoral insertion of the MPFL and related osseous structures were analyzed.
The MPFL was identified in all knees. The femoral insertion of the MPFL was elliptical in shape, and the mean surface area was 56.5 ± 16.9 mm(2). The characteristic features of the femoral insertion of the MPFL could not be identified, but the adductor tubercle was clearly identified in all knees. The centre of the femoral insertion of the MPFL was 10.6 ± 2.5 mm distal to the apex of the adductor tubercle on the long axis of the femur, and the position of the insertion site was consistent in all knees.
The adductor tubercle was clearly identified as an osseous landmark. The femoral insertion of the MPFL was approximately 10 mm distal to the adductor tubercle. These findings may improve understanding of the anatomy of the femoral insertion of the MPFL and may assist surgeons in performing anatomical reconstruction.
本研究的目的是确定髌股内侧韧带（MPFL）的股骨附着点及相关骨性标志。
共研究了31个未配对的人体尸体膝关节。识别出MPFL，并标记其股骨附着点。创建三维图像，分析MPFL股骨附着点及相关骨性结构的位置和形态。
所有膝关节均识别出MPFL。MPFL的股骨附着点呈椭圆形，平均表面积为56.5±16.9平方毫米。MPFL股骨附着点的特征无法识别，但所有膝关节均清晰识别出内收肌结节。MPFL股骨附着点的中心在股骨长轴上距内收肌结节顶点远端10.6±2.5毫米处，且所有膝关节的附着点位置一致。
内收肌结节被明确识别为一个骨性标志。MPFL的股骨附着点在内收肌结节远端约10毫米处。这些发现可能会增进对MPFL股骨附着点解剖结构的理解，并可能有助于外科医生进行解剖重建。
