The intercondylar fossa indices of male and female dog femora.

The intercondylar fossa (ICF) indices can be used to evaluate fossa geometry, which may in turn affect the function, pathology and intracapsular surgical repair of the cranial cruciate ligament. The measurements of digital images of the distal femur of 44 dogs were used to calculate the fossa width, shape, height and area indices. The mean values of fossa width index were found to be 0.19, 0.28 and 0.37 at the cranial, central, and caudal levels of the fossa, respectively. The mean values for fossa shape, height and area indices were found to be 0.71, 0.33, and 0.16, respectively. The differences in ICF indices between male and female dog were not significant. Therefore, it is suggested that gender differences related to ICF geometry may not have any effect on incidence of cranial cruciate ligament injury in dogs.
