The purpose of this study was to compare the measurement of several anatomical features of the medial patellofemoral ligament (MPFL) between magnetic resonance imaging (MRI) and by direct fashion during dissection. We hypothesized that the measurements between these two techniques would agree. MRI of 30 fresh-frozen cadaveric knees was followed by dissection. MPFL patella and femoral attachment were evaluated; their shape, length, and width were measured; and measurements were compared. MRI was deemed unreliable for the determination of several of the aforementioned anatomical features. Important findings include: (a) observations on MPFL attachment at medial patella side and attachment to quadriceps were identical between dissection and MRI; (b) average width at patella insertion was significantly different between the two methods ( = 0.002); and (c) an attachment to the quadriceps tendon was present in 20/30 specimens and d. detailed measurements of a thin, non-linear, and three-dimensional structure, such as the MPFL, cannot be performed on MRI, due to technical difficulties. This anatomical radiological study highlights the shape, anatomical measurements (length and width), and attachment of the MPFL using a relatively large cadaveric sample and suggests that MRI is not reliable for detailed imaging of its three-dimensional anatomy.
本研究的目的是比较磁共振成像（MRI）与解剖时直接测量内侧髌股韧带（MPFL）的几个解剖学特征的差异。我们假设这两种技术的测量结果会一致。对30个新鲜冷冻尸体膝关节进行MRI检查后再进行解剖。评估MPFL在髌骨和股骨上的附着情况；测量其形状、长度和宽度，并比较测量结果。结果发现，MRI对于确定上述几个解剖学特征并不可靠。重要发现包括：（a）解剖和MRI在MPFL在髌骨内侧的附着以及与股四头肌的附着观察上是相同的；（b）两种方法在髌骨插入处的平均宽度有显著差异（P = 0.002）；（c）30个标本中有20个存在与股四头肌腱的附着；（d）由于技术困难，无法在MRI上对MPFL这样的薄的、非线性的三维结构进行详细测量。这项解剖放射学研究使用相对较大的尸体样本突出了MPFL的形状、解剖学测量（长度和宽度）以及附着情况，并表明MRI对于其三维解剖结构的详细成像并不可靠。
