The new study randomized 40 patients to get either a steroid shot or PRP injection via ultrasound guidance. The patients were then followed only short-term up to three months (which is a weakness of this study). Back pain was less with PRP at six weeks and three months. Only 25% of the patients who had a steroid injection were still experiencing significant relief at three months compared to 90% of the PRP group. Functional scores worsened at three months for the steroid group while these same scores improved gradually for the PRP group. In summary, PRP beat steroid in this small study.
