Anthropometric Measurements of the Distal Femur in Adult Sudanese Population

 Acquiring knowledge about anatomic and geometric measurement of bone is among the most vital parameters in knee arthroplasty and has a significant effect on the subsequent outcomes. The aim of this study is to obtain anthropometric measurements of the distal femur of adult Sudanese Population and to compare the results with other populations.

 This descriptive study conducted at Alamal hospital in Khartoum, Sudan, between Sep. 2020 and Feb. 2021, included all adult patients attending the radiology clinic for CT scan with normal knees. The Femoral medio-lateral (ML) and anteroposterior (AP) dimensions of the distal femora were measured. The collected data was analysed using statistical package for social science (SPSS).

 385 adult Sudanese were studied. The mean age was 59.1±18.5 years (Range 20-86 years). 69.9% were male and 30.1% female. 45% were left knees and 55% right. The mean ML diameter was 76.6±6.0mm (rang 66.7-88.2mm), and the mean of AP was 45.640±4.9 mm (range 37.2-54mm). The anthropometric measurements of the distal femur of Sudanese people fall between Greek and Korean.

 There were differences in mean ML and AP dimensions between the Sudanese population and other ethnic groups which should be kept in mind when designing Total Knee Arthroplasty implants.
