Fig. 10.

With revised constraint of $\mathit{\xi }\mathit{ϵ}\left[0,{10}^{\circ }\right]$, results of post hoc tests on GOH model’s $\mathit{\xi }$ (preferred fiber direction). Effects of injury on preferred direction within: both aging (b) and aged (c) groups exhibited statistical trend toward decrease post-injury (0–3 weeks), the aged group (c) exhibited statistical significant increase during healing (3–6 weeks). The mature group exhibited neither statistical significance nor trend with injury. Data are presented as mean ± standard error. Significance is denoted by * ($p<0.05$); statistically significant trend is denoted by # ($p<0.1$)
