Biomechanical tests of normal tendon and regenerated tendons 3 weeks after surgery. Ultimate tensile stress (a) and Young’s modulus (b) of the 29-mer/alginate group (n = 8) and vehicle group (n = 8) were calculated from the axial force–axial displacement curve. The contralateral intact tendon was used as the control (n = 16). *P < 0.05 versus vehicle-treated group
