    The study compares the Reamer-Irrigator-Aspirator (RIA) 2 system and the aspirator+reaming-aspiration (ARA) concept for intramedullary bone graft harvesting.

  • 2

    The RIA 2 system is associated with good bone graft quality but carries risks of blood loss and complications due to aggressive reaming.

  • 3

    The ARA concept offers a potentially safer alternative, using standard reamers without irrigation fluid and showing strong osteogenic potential.

  • 4

    A large animal study was conducted to evaluate the mechanical properties and biomechanical stability of reamed sheep femora using both techniques.

  • 5

    Ethical approval was obtained, and the study adhered to ARRIVE 2.0 guidelines, ensuring methodological rigor and transparency in animal research.
