In some non-limiting examples, a system for stimulating tissue growth at a tissue site may include an interactive body including a body mass and a tissue contact surface configured to contact the tissue site. A plurality of struts and a plurality of voids may be exposed at the tissue contact surface, and may define a tissue interface pattern at the tissue contact surface. The tissue interface pattern may be configured to engage the tissue site and to create tissue deformation in combination with the body mass. Also provided are other systems, apparatus, and methods suitable for stimulating tissue growth.
