Purpose: This study was conducted to histopathologically compare the results of the administration of intra-articular PDRN and HA injections in experimentally induced OA in rats. Methods: Osteoarthritis of the knee joints was induced in a total of 30 rats. Rats were randomly divided into three groups; polydeoxyribonucleic (PDRN) acid group, hyaluronic acid (HA) group, and saline group. The PDRN group was injected with 12 mg/0.05 ccPDRN acid. The HA group was injected with 12 mg/0.05 ccHA, whereas the saline group was injected with 50 μ l (0.05 cc) of 0.9% sodium chloride solution. All rats were sacrificed on postinjection day 29, and the right knee joints were prepared and evaluated histologically using the Mankin scoring system. Results: Total Mankin scores showed a significant difference among all groups (p = 0.001). According to bilateral comparisons performed to identify the group that showed a difference, the total Mankin scores of the PDRN acid and HA groups were found to be significantly lower than those of the saline group. In PDRN acid group, tidemark continuity wasobserved in all specimen. Conclusion: Intra-articular injections of PDRN acid resulted in greater chondroprotective effects and less degeneration than those of HA and saline in experimentally induced OA of the knee joints in rats.
