Morphological and morphometric features of knee joint in wild boar (Sus scrofa)

In the study, it was aimed to reveal the structure of the knee joint anatomically and morphometrically in the wild pig known as the ancestor of the domestic pig. In the study, the left and right knee joints of mature 10 wild boars were used as material. For this purpose, the materials were fixed with 10% formaldehyde solution. Macroanatomical and morphometrical examinations of bones, menisci and ligaments involved in joint formation were performed after fixation. Trochlea and condyles of femur were examined, and various measurements were made. Trochlear labia were found to be the same size, and the condyles did not show a significant difference in size. The shape of lateral condyle of the tibia was trapezoid, and the shape of medial condyle was triangular. Moreover, the lateral intercondylar tubercule was higher according to the medial one. The presence of a shallow groove on the tibial tuberosity was detected. It was found that the width difference between apex and base was more pronounced on the anterior and lateral surface of the patella. Joint surface of the fibula was found to be flat in all materials. The menisci were 'C' shape, but the medial meniscus is more convex than the lateral one. It was observed that the outer edges were thick, while the inner edges were thin. Ligaments of the knee joint were well developed. When the findings of the study were compared with the literature, domestication seemed to have no significant effect in terms of the morphologic properties of the knee joint of wild boar.
