This study provides the geometry of patella and patellar tendon measured on sagittal and axial magnetic resonance images of 172 knees (142 males, 30 females) of 163 subjects (135 males, 28 females) whose mean age was 26.7. The gender difference and the relationship with anthropometry were also given. As for patella, the longitudinal lengths of the whole and articulating surface were 44.6, 32.9 mm, and the thickness was 22.3 mm. The mediolateral width was 45.8 mm, and the central ridge was located 19.9 mm or 43% lateral from the medial border. As for patellar tendon, the longitudinal length was 40.2 mm. The widths of proximal and distal part were 30.3, and 24.0 mm. The thicknesses of proximal and distal part were 3.2, and 5.0 mm. The geometry of the patella and patellar tendon was larger in male than in female (P < 0.001). Anthropometry including weight, height, body mass index corresponds well with the thickness of patella but poorly with the length of patellar tendon. These data can provide useful information in the field of knee surgery and sports medicine.
本研究提供了对163名受试者（135名男性，28名女性）的172个膝关节（142名男性，30名女性）进行矢状面和轴向磁共振成像测量得到的髌骨和髌腱的几何数据。研究还给出了性别差异以及与人体测量学的关系。对于髌骨，整体长度和关节面长度分别为44.6毫米和32.9毫米，厚度为22.3毫米。内外侧宽度为45.8毫米，中央嵴位于距内侧边缘19.9毫米处或内侧边缘外侧43%处。对于髌腱，纵向长度为40.2毫米。近端和远端宽度分别为30.3毫米和24.0毫米。近端和远端厚度分别为3.2毫米和5.0毫米。男性的髌骨和髌腱几何尺寸大于女性（P < 0.001）。包括体重、身高、体重指数在内的人体测量数据与髌骨厚度相关性良好，但与髌腱长度相关性较差。这些数据可为膝关节手术和运动医学领域提供有用信息。
