Comparison of CT-guided platelet-rich plasma versus steroid/anesthetic injection for treatment of sacroiliac joint pain: a randomized, single-blinded, controlled trial

PRP and SAI both improved SIJ-related LBP, with PRP demonstrating a slower onset but potentially more durable benefit. PRP appears to be a viable, safe alternative to corticosteroids in managing chronic SIJ pain. Larger trials with longer follow-up are warranted to validate these findings and inform clinical guidelines.
