a) Micro-CT was performed to evaluate the cross-sectional area of the tibial tunnel in the secretory leucocyte proteinase inhibitor (SLPI) and negative control (NC) groups at two, four, and eight weeks (n = 4). The planes (yellow dashed circle) were chosen at a depth of 5 mm from the tibial plateau. b) Results of bone tunnel area, bone volume/total volume (BV/TV (%)), and bone mineralization density (BMD) of the samples from each of the two groups at two, four, and eight weeks. The results are expressed as mean and standard deviations, *p < 0.05; **p < 0.01. The red dashed line indicates the outline of the bone tunnel.
