Abstract：Objective To discuss the measurement of normal knee parameter of Uyghur with CT and its clinical significance and instructive significance in the design of total knee arthroplasty . Methods Totally 120 healthy volunteers[62 males,58 females,ranged 18-70 years,average (35.1 ±2.7) years] were included in this study.CT scan examinations were performed in the volunteers in straight neutral position .Parameters ( left or right knee, selected randomly) of patellar thickness,angle PT,angle FT,distance of tibial plateau to fibular head(DPF) were measured and recorded after the images reconstructed by AW 4.4.When the values were obtained , they were statistically analyzed based on gender and compared with data of Han people .Results Significant differences exis-ted between male and female of Uyghur in these parameters of patellar thickness ,angle PT,angle FT,DPF.Except for DPF,no significant differences existed between Uyghur and Han people for the above parameters .Conclusion Related parameters of other races should not be directly referred to when performing surgeries such as total knee ar -throplasty in Uyghur .The race and gender difference should be taken into account in design of knee joint prosthe -sis.
