The mean IFS was 20.88 \u00b1 5.96\u2009mm, mean QFS was 15.2 \u00b1 6.18\u2009mm, mean FVA was 12.43 \u00b1 6.98, and mean CDA was 121.27 \u00b1 4.6\u00b0. The IFS measurements were significantly correlated with femoral measurements (p = 0.025). These visible differences showed a slight negative relationship (\u22120.191), and females had a smaller distance between these anatomical structures than males (p &amp;lt; 0.001). Females had a significantly smaller QFS than males (12.42 \u00b1 5.94 vs 18.73 \u00b1 4.48\u2009mm, p = 0.000). There was a small but significant positive relationship between CDA and FVA (p = 0.022), with a correlation coefficient of 0.195.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>A higher FVA was correlated with a smaller IFS.
