Objective: Investigate the efficacy of ultrasound guided platelet-rich plasma in reducing sacroiliac joint disability and pain. Design: Prospective non-randomized interventional study analyzing 50 patients with low back pain secondary to sacroiliac joint dysfunction. Platelet-rich plasma was injected into the sacroiliac joint under ultrasound guidance. Oswestry Disability Index (ODI) and Numeric Rating Scale (NRS) were measured at baseline, 2 weeks, 4 weeks, 3 months, and 6 months post-injection. Results: Mean reduction in Oswestry Disability Index and Numeric Rating Scale scores were significantly reduced at 6 months post-injection compared to baseline values (M -9.79%; [95% CI: -6.06, -13.52]) and (M -1.94; [95% CI -1.14, -2.78], respectively. All time frames showed significant mean reduction compared to baseline, but overall improvement tapers off after 4 weeks with no statistically significant reduction from 4 weeks to 3 months or 3 months to 6 months. Conclusions: Ultrasound guided platelet-rich plasma injections in the sacroiliac joint are effective at reducing disability and pain with the majority of improvement seen within 4 weeks post-injection and with sustained reduction at 6 months.
