abstract = {{Objectives: Extant humans and non-human apes are characterized by diverse locomotor and postural behaviors, resulting in {\textless}br{\textgreater}different joint loading patterns. These behaviors influence trabecular bone, which responds to mechanical loading and joint pos-{\textless}br{\textgreater}ture. While prior studies have examined femoral trabecular structure, this study is the first to assess trabecular architecture in {\textless}br{\textgreater}the proximal tibia across extant hominoids to evaluate how differences in joint use and posture are reflected in tibial morphology. {\textless}br{\textgreater}Materials and Methods: We analyze trabecular structure in the proximal tibiae of Homo sapiens (n {\textequals} 25), Gorilla (n {\textequals} 13), {\textless}br{\textgreater}Pan troglodytes (n {\textequals} 15) and Pongo sp. (n {\textequals} 7). Each tibia was scanned using high-resolution microtomography, and cortical and {\textless}br{\textgreater}trabecular bone were isolated from each other. Canonical holistic morphometric analysis was used to quantify trabecular bone {\textless}br{\textgreater}volume fraction and degree of anisotropy. Spatial distributions of these variables were compared across taxa using principal com-{\textless}br{\textgreater}ponent analysis, and group differences were assessed with multivariate analysis of variance and pairwise tests.{\textless}br{\textgreater}Results: Results show that trabecular bone volume and anisotropy reflect habitual knee posture: extended in bipedal Homo, and {\textless}br{\textgreater}flexed in non-human apes. In Gorilla, males exhibit more extended knee use than females, while no significant sex differences {\textless}br{\textgreater}were observed in Homo or Pan (sex differences in Pongo were not tested due to sample limitations).{\textless}br{\textgreater}Discussion: We demonstrate that the trabecular structure of the proximal tibia is consistent with habitual locomotor loading in {\textless}br{\textgreater}extant hominids, which provides the comparative context to interpret knee posture, biomechanical loading, and predominant {\textless}br{\textgreater}locomotor behaviors in fossil hominids.}},
