The mean improvements from before treatment until the second, sixth, and twelfth months post-intervention in scores obtained by visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index were our primary outcomes.Results: A total of 102 candidates were finally included in the study. Patients’ mean age was 57.08± 7.3 years old in the PRGF group compared to the mean age of 58.63± 7.09 years old in HA patients. In the PRGF group, total WOMAC index decreased from 41.96± 11.71 to 27.10± 12.3 (P = 0.02), and from 39.71± 10.4 to 32.41± 11.8 in the HA group after 12 months (P > 0.05). Regarding the Lequesne index, pain, ADL, and global scores significantly decreased after 12 months in the PRGF group compared to the HA group (P< 0.001). There was also a meaningful higher rate of satisfaction in the PRGF group compared to the HA group after 12 months of treatment (P< 0.001).Conclusion: Besides significantly higher satisfaction belonging to the PRGF group, there was a statistically significant improvement in VAS score and global, pain, and ADL score of Lequesne by passing 12 months from injection in PRGF compared to HA.Keywords: knee, osteoarthritis, PRP, PRP-derived growth factor, hyaluronic acid, intra-articular injections
