Mechanical properties. (a) Full tendon and (b) injury site cross-sectional area, (c) percent relaxation, (d) max displacement, (e) stiffness, and (f) max load, (g) max stress, (h) tendon and (i) injury site modulus, (j) dynamic modulus, and (k) tan delta. The vascular endothelial growth factor (VEGF) group percent relaxation was decreased and the max load and injury site modulus were increased compared to the saline control (SAL). Solid bars indicate p < 0.05 and dashed bars indicated p < 0.1.
