Effects of moderate-intensity treadmill rehabilitation training on mice knee cartilage (A section-diagram of moderate-intensity treadmill running mice knee cartilage with hematoxylin–eosin staining and safranin O–fast green stain under the 200-fold light microscope; B Mankin and OARSI score of hematoxylin–eosin staining and safranin O–fast green stain of the knee cartilage of mice with moderate-intensity treadmill running. RC group: rehabilitation control group, M + R group: treadmill model + rehabilitation training group, and M + C group: treadmill model + convalescent group. n = 6, *P < 0.01, **P < 0.01, Mankin scores; ^##P < 0.01, OARSI score)
