Twelve weeks after implantation, micro-CT images of the distal femur, and quantitative results of implant osseointegration and peri-implant trabeculae by micro-CT assessment. All micro-CT images of groups Control (a), MK (b), PTH (c) and PTH + MK (d) were obtained from transverse slices 2 mm below the epiphyseal plate of femur to the distal 100 slices. Bone volume per total volume (BV/TV) (e), trabecular number (Tb.N) (f), thickness (Tb.Th) (g), mean connective density (Conn.D) (h), and mean trabecular separation (Tb.Sp) (i). Data are expressed as mean ± SD, N = 10 specimens/group. *vs Control, P < 0.05; #vs MK group, P < 0.05; &vs PTH group, P < 0.05 (by one-way ANOVA and Tukey’s post hoc test)
