CHARACTERIZATION OF KNEE JOINT CHANGES IN SUDANESE USING PLAIN X-RAY

Abstract

The aim of this study was to characterize knee joints changes in Sudanese population using plain x-ray, in order to comprehend the potential pathological changes that might appears in the plain x-ray film also to calculate bone size for artificial knee joint before surgery. A total of 257 symptomatic knee joints were enrolled in this study,106 showed no change in the x-ray film ‘normal’, (56 male and 50 female), 151 showed change of knee joint in the plain x-ray (55 males and 96 females).Their age range from18 to 78 years. In this study also study found that the mediolateral femur measurements for male is equal to 6.4 ±1.03 and 5.9± 0.7 for female and the mediolateral tibia measurements is equal to 6.8 ± 0.9 for male and 6.3 ± 0.6 for female. These differences were significant at p=0.05 using the t-test with t=2.62 for male and t=3.07 for female and p=0.04 and 0.02 respectively. The mediolateral femur and tibia measurement were significantly correlated with the height and circumference of the knee, as well these measurements were correlated significantly with the artificial femur and tibia size. Also this study found that the diagnosis = [(TL2X×0.86) + (FL1X×-0.29) + (TW3X×0.63) + (TL1X×0.38)] – 5.85. To identifies the normal for symptomatic cases where the result =1, the patient were normal otherwise patient were affected.
