Morphologies of the knee meniscus and HE staining on the rabbits at the 2nd, 4th, and 8th weeks after the operation in the PLB groups and sham 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 PLB groups. c Structures of the knee meniscus and HE staining on the rabbits sacrificed after 4 weeks were imaged in the PLB groups. d Structures of the knee meniscus and HE staining on the rabbits sacrificed after 8 weeks were imaged in the PLB groups.
