Quantification of tendon healing. A: The overall scores of the repaired tendons in three study groups. At day 6, tendon repair was significantly improved in group M + S. B: The angiogenesis scores of the repaired tendons. At day 6, angiogenesis in group M + S was significantly less than groups M and Sut. C: The collagen scores of the repaired tendons. The scores of collagen bundles in group M + S showed significant improvement at day 14. D: No differences were found among groups in cellularity score (*p < 0.05; **p < 0.001).
