Biomechanical testing of the ACLR tissue after the treatment of BMSC-Exos. A Flowchart of the group allocation and analysis items at each time point. B The scheme of the ACLR operation. C Biomechanical test of the reconstruction ACLR tissue using a mechanical tester. D The maximal failure load and E stiffness of the femur-graft-tibia complex after ACLR at 4 and 8 weeks postoperatively among the control group, the BMSC-Exos group and the BMSC-Exos mimic group. Data are presented as mean ± SD. Statistical analysis was performed with one-way ANOVA followed by Tukey’s multiple comparisons test. n = 6. *P < 0.05, **P < 0.01.
