To evaluate the effects of systemic medical ozone (O
We performed anterior cruciate ligament transection (ACLT) in order to create experimental OA in the right knees of 27 male rats. The left knee joints of all rats were sham-operated without ACLT as the negative control group. The rats were randomly assigned into three groups: (1) control group, which received no treatment; (2) O
As a result of histopathological examination, the mean Mankin scores in the right knees with ACLT were 8.17 ± 2.12 in the control group, 6.22 ± 1.56 in the HBO group, and 4.72 ± 1.30 in the O
The results of the present study show that systemic medical O
