亚洲人和白人的膝关节在人体测量上是否存在差异尚不清楚。采用计算机断层扫描或磁共振成像技术建立了中国和白人健康受试者的三维膝关节模型。股骨的形态学测量包括中外侧、正前方尺寸和长径比。胫骨测量包括内侧、内侧/外侧前后位尺寸、宽高比和内侧/外侧平台后斜率。结果表明，中国人的膝盖普遍小于白人的膝盖。此外，华裔女性股骨长径比（1.24±0.04 vs 1.28±0.06）显著小于白人女性。中国男性和白人男性的胫骨宽高比差异（1.82±0.07 vs 1.75±0.11）虽然显著，但可能反映了种族间膝关节大小的差异。在为亚洲人群设计全膝关节置换术时应考虑到这些种族差异。
Whether there are differences in knee anthropometry between Asian and white knees remains unclear. Three-dimensional knee models were constructed using computed tomography or magnetic resonance imaging of healthy Chinese and white subjects. The morphologic measurements of the femur included mediolateral, anteroposterior dimensions, and aspect ratio. The tibial measurements included mediolateral, medial/lateral anteroposterior dimension, aspect ratio, and posterior slope of medial/lateral plateau. The results showed that Chinese knees were generally smaller than white knees. In addition, the femoral aspect ratio of Chinese females was significantly smaller than that of white females (1.24 ± 0.04 vs 1.28 ± 0.06). Tibial aspect ratio differences between Chinese and white males (1.82 ± 0.07 vs 1.75 ± 0.11), though significant, were likely a reflection of differences in knee size between races. These racial differences should be considered in the design of total knee arthroplasty prosthesis for Asian population.
