Table 1 Mechanical properties of porous tantalum (pTa), solid tantalum (sTa), and bone tissues

From: Mesenchymal stem cell-loaded porous tantalum integrated with biomimetic 3D collagen-based scaffold to repair large osteochondral defects in goats

Sample All pore mean size (μm) Open porosity (%) Tantalum coating thickness (μm) Compressive strength (MPa) Young’s modulus (GPa)
pTa 200–500 75–85 15–30 30–90 10–30
sTa     Not available 186–191
Cortical bone     100–230 7–30
Cancellous bone     2–12 0.01–3
