In this study, it was aimed to make three-dimensional reconstruction of the stifle joint computed tomography (CT) images of the Van cats, to obtain their osteometric measurements, and to determine the statistical biometric differences of these measurement values in terms of both sexual dimorphism and homotypic variations. A total of 16 healthy adult Van cats of both sexes were used. The stifle joints of the cats were scanned with a CT device and images were obtained. Three-dimensional reconstructions of the bony structures of the stifle joint were performed using CT images using the MIMICS 20.1 modelling program. Then, osteometric measurements were calculated, and statistical analysis was performed. When the morphometric measurement values were examined in terms of gender, it was observed that almost all of the osteometric measurement values of the stifle joint in Van cats (except SPW measurement) were higher in male cats. According to homotypic variations, right side TPW (p = 0.009), TPCMA (p = 0.003) and TPMCA (p = 0.032) measurement values in female cats and right side TPLCA (p = 0.002) measurement values in male cats were found to be statistically significantly higher than the left side from the measurements of only the proximal tibia (p < 0.05). In general, although there were negative correlations between morphometric measurement values with age and body weight, mostly strong positive correlations were seen. As a result, statistical differences of the biometric values and anatomical features of the stifle joint between the sexes in Van cats between the sexes were examined using CT and a three-dimensional modelling program.
