Morphologies of the knee meniscus and HE staining on the rabbits at the 2nd, 4th, and 8th weeks after the operation in the AMB groups and control groups (HE staining ×400). a Structures of the knee meniscus and HE staining on the rabbits sacrificed after 2 weeks were imaged in the sham control groups. b Structures of the knee meniscus and HE staining on the rabbits sacrificed after 2 weeks were imaged in the AMB groups. c Structures of the knee meniscus and HE staining on the rabbits sacrificed after 4 weeks were imaged in the AMB groups. d Structures of the knee meniscus and HE staining on the rabbits sacrificed after 8 weeks were imaged in the AMB groups.
