Fig. 5. Biomechanical tests among the groups. (A) The ultimate load-to-failure is significantly higher in the repair + PRP + BMAC (RPB) group than the repair + saline (RS) group. (B) Stiffness is significantly higher in the repair + BMAC (RB) group than both the RS and repair + PRP (RP) groups. (C) The Young's modulus is significantly lower in all experimental groups than the control group. (D) Yield strength of the RB and RPB groups showed no statistical differences from the control group. Asterisks and error bars show the statistical difference between the two groups (*p < 0.05). C: control, PRP: platelet-rich plasma, BMAC: bone marrow aspirate concentrate.
