摘　　要：目的探讨西北地区国人正常離股关节CT影像相关解剖学测量数据在不同性别间差异,为人工膝关节假体设计提供参考。方法收集2017年5月-8月西安交通大学第二附属医院招募的78名志愿者156侧正常膝关节CT影像资料进行横断面研究。采用美国GE Revolution CT机,对78名志愿者自骼棘至足底进行CT扫描及三维重建,测量两侧離骨厚度、離骨关节面厚度、離骨宽度、離骨外侧关节面宽度、離骨纵向长度、濮骨关节面长度、股骨左右径、股骨前后径、前股骨偏心距、滑车沟角。采用独立样本/检验分析不同性别间各观测指标的差异;应用线性回归模型控制年龄、身高、体质量偏倚,再次分析不同性别间各测量指标的差异,并对所有观测指标进行Pearson相关分析。结果78名志愿者,不同性别间年龄、身高、体质量、BMI比较,差异均有统计学意义(t=6.270、17.602、11.366、4.377,P值均<0.01)。在控制年龄、身高、体质量偏倚前,男性離骨厚度、離骨关节面厚度、離骨宽度、離骨外侧关节面宽度、離骨纵向长度、離骨关节面长度、股骨左右径、股骨前后径、前股骨偏心距分别为(22.39±1.53)mm,(11.75±0.94)mm.(47.04±2.81)mm.(27.18±2.16)mm、(45.18±2.74)mm、(30.60±2.28)mni、(86.31±3.94)mm、(66.76±3.26)mm、(6.37±1.38)mm,均明显大于女性的(19.75±1.29)mm.(10.91±0.95)mm、(40.47±2.30)mm、(23.37±1.61)mm.(38.74±2.51)mm、(26.76±1.70)mm,(74.28±3.00)mm、(60.07±2.89)mm、(5.63±1.36)mm,差异均有统计学意义(211.692、5.582、16.024、12.518、15.303、11.969、21.545、13.581、3.381,P值均<0.01);控制偏倚后,離骨关节面厚度和前股骨偏心距男性、女性之间差异均无统计学意义(P值均〉0.05),其他指标男性、女性之间差异仍均有统计学意义(t=2.057、6.581.5.207、4.673、3.045、8.053、2.331,P值均<0.05)。而滑车沟角男性为139.43°±4.78°,女性为138.29°±4.22°,无论是否控制年龄、Objective To explore the differences of CT image-related anatomical measurements of normal patellofemoral joints between genders in Northwest China, and to provide reference for design of knee prosthesis.Methods CT data of normal knee joints of 78 volunteers (156 sides) recruited in the Second Affiliated Hospital of Xi'an Jiaotong University from May 2017 to August 2017 were collected for crosssectional study.Using GE revolution CT machine, 78 volunteers were scanned from spina iliace to pelnia. After three-dimensional reconstruction, patella thickness, patella facet thickness, patella width, patella lateral facet width, longitudinal length of the whole patella, longitudinal length of the articulating surface of the patella, the inediolateral and anteroposterior sizes of the femur, anterior femoral offset, and sulcus angle were measured respectively.Two-sample t-test for independent samples was used to analyze the differences ainong different genders.Linear regression model was used to control the bias of age, height and weight, and then the gender (iifferences of measurement parameters were analyzed again.Pearson correlation analysis was performed for all parameters.Results There were significant differences in age, height, weight and BMI between different genders in 78 volunteers (t=6.270, 17.602,11.366, 4.377,all P values<0.01). Before controlling age, height and weight bias, patella thickness, patella facet thickness, patella width, patella lateral facet width, longitudinal length of the whole patella, longitudinal length of the articulating surface of the patella, the mediolateral and anteroposterior sizes of the femur, and anterior femoral offset in male group were (22.39±1.53) mm,(11.75±0.94) mm,(47.04±2.81) mm,(27.18 ±2.16) mm,(45.18 ±2.74) mm,(30.60 ±2.28) mm,(86.31 ±3.94) mm,(66.76±3.26) mm,(6.37±1.38)mm, respectively, which were significantly larger than those of females,(19.75±1.29) mm,(10.91 ± 0.95) mm,(40.47±2.30) mm,(23.37 ±1.61) mm,(38.74±2.51) mm,(26.76±1.70) mm,(74.28 ± 3.00) mm,
