Biomechanical properties of repaired Achilles tendons at 28 days post injury. (A) By 28 days, control tendons had a 20% re-rupture rate (3/15), while no ruptures were observed with dACM-treated tendons; (B) maximum tensile load for both control and dACM-treated tendons retrieved 28 days post injury; (C) stiffness of control and dACM-treated tendons 28 days post injury. Representative force-displacement curves for (D) non-injured sham tendons (intact), (E) repaired control, and (F) repaired dACM-treated tendons at 28 days post injury. Red dot indicates the maximum failure load.
B and C: Averages are presented, and error bars represent standard deviation; N=5.
