Comparisons between shear wave velocities in rat Achilles tendons in vivo and post-mortem analyses of biomechanical properties of the same tendons. Measurements were performed at 4 weeks after tenotomy and on a separate group of healthy rats. Significant correlations were obtained between shear wave velocity and the Young’s modulus (R2 = 0.87, p = 5.0 × 10–12, as indicated) and the maximum tensile stress (R2 = 0.81, p = 9.0 × 10–10, data not shown). The significant correlations between in vivo and ex vivo data provided a valid basis for clinical assessments of injured tendons by SWE.
