Efficacy of platelet-rich plasma for sacroiliac joint dysfunction: a qualitative systematic review with pooled analysis

Plain language summaryPlatelet rich plasma is an injection derived from separating blood components in a centrifuge. Injection of platelet rich plasma into the sacroiliac joint has often been touted as highly beneficial for pain and disability, and superior to other modalities. Our systematic review and pooled analysis show that platelet rich plasma injections are beneficial, albeit not to the degree previously reported. Aim: We aimed to expound upon previous research examining the effect of platelet rich plasma in the treatment of sacroiliac joint (SIJ) dysfunction and pain. Materials & methods: A systematic review was employed in conjunction with a pooled analysis of the efficacy of platelet-rich plasma (PRP) in SIJ dysfunction and pain. Results: A total of 259 articles were retrieved following database systematic review. As a result, four clinical trials and two case studies were subjected to full text appraisal. The dates of publication ranged from 2015 to 2022. Conclusion: Although a unique modality, there is not enough evidence to support the employment of PRP injections over current steroid standard of care. Further double-blinded, randomized control trials are required to elucidate PRP role in SIJ dysfunction.
