Radiological assessment of femoral bicondylar angle among persons attending a tertiary health care
Femoral bicondylar angle is the angle between an axis through the shaft of the femur and a lineperpendicular to the infracondylar plane. This study aims to assess femoral bicondylar angle measuredfrom radiograph of femur and knee joints obtained from teaching hospitals in Kathmandu Nepal. Totalof two hundred AP view radiograph of knee joint were collected, out of which, 50 each were of male rightand left knee joint and 50 each were of female right and left knee joint. The mean angle for the right malefemur was 7.86° with the range of 5°-10° and mean angle for the right female femur was 8.82° with therange of 6°-11°. On the left side, bicondylar angle ranged in male from 6° -10° with the average of 7.46°andin female range was 6°-11° and average was 8.66°. The bicondylar angle was higher in female on both theside, the difference was statistically significant on the left side (P=0.004) and significant on the right side(P=0.001). The finding of the study showed the femoral bicondylar angles were greater in right femurthan left femur in both sexes. The difference in the bicondylar angle between the right and left femurwas statistically insignificant in both sexes. (male p=0.144, female p=0.541). The result from this study hasshown that femoral bicondylar angles were generally greater amongst the females as compared to themales; greater in right femur than left femur in both sexes.
