μ-CT evaluation for the in vivo degradation and bone formation under normal and bacteria-infection conditions. Reconstructed micro-CT images of metaphyseal bone within the defective region (red dotted line) in (A) normal and (B) bacterial models at 4 weeks postoperatively. Upper right corner of each sample: the new bone formation within the defective region (gray). Bottom right corner of each sample: the residual alloy materials (white). (C) BV/TV: the percent volume of the newly formed bone (BV) relative to the total volume of the defect area. (D) The volume reduction rate of the implants: the percent volume of the degraded materials (ΔMV) relative to their paired initial volume (MV). (*p < 0.05, **p < 0.01, ***p < 0.001)
