Abstract
The aim of this study was to determine if there is a difference in the presence of the femoral footprints (lateral intercondylar ridge and the lateral bifurcate ridge) between patients with acute and chronic ACL injuries. Our study consisted of 83 patients with acute ACL injury and 17 patients with Chronic ACL injury. The femoral footprints (lateral intercondylar ridge and lateral bifurcate ridge) were scored as either present or absent. The femoral footprints were present in 93% of the acute patients and 47% of the chronic patients. We concluded that the femoral footprints were present less often in chronic ACL patients than in acute ACL patients.
