[en] We highlighted a morphological protrusion facilitating load transmission from the Achilles tendon to the plantar ligament through bone in adult rats. The roughness at the tendon insertion is probably due to mineralization gradients within fibrocartilage and may enhance interface toughness. Despite the low porosity and consequently high rigidity of the tuberosity, this region contains anisotropic pores likely oriented to minimize peak stresses. Our results suggest that not only the interface but also the underlying bone is well-adapted to accommodate tendon loading.
