This significant effect on pain was also seen when PRP injections were compared with hyaluronic acid injections. Additionally, function improved significantly more when PRP injections were compared with controls. (Source: Laudy A, et al. Efficacy of Platelet-Rich Plasma Injection in Osteoarthritis of the Knee.
