ObjectiveTo determine the effectiveness of platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) for the treatment of suspected sacroiliac joint complex (SIJC) pain.DesignSystematic review.SubjectsPersons aged ≥18 with suspected SIJC pain.ComparisonSham, placebo procedure, or active standard of care treatment.OutcomesThe primary outcome was ≥50% pain improvement, and the secondary outcome was functional improvement of ≥30% at three or more months after the treatment intervention.MethodsPublications in PubMed, MEDLINE, Embase, Scopus, and Cochrane Databases were reviewed up to April 3, 2019. Randomized or nonrandomized comparative studies and nonrandomized studies without internal controls were included. The Grades of Recommendation, Assessment, Development, and Evaluation system and the joint consensus American Academy of Orthopedic Surgery/National Institutes of Health recommendations were used for quality assessment and reporting standards.ResultsQuery identified 151 publications; three were appropriate for inclusion. There were no studies of BMAC that met inclusion criteria. There were three eligible PRP studies: one randomized comparative trial (RCT) and two case series. In the single RCT comparing ultrasound-guided PRP with corticosteroid injection for suspected SIJC pain, the PRP group had a significantly increased likelihood of achieving ≥50% improvement of pain at three months (adjusted odds ratio = 37, 95% confidence interval [CI] = 4.65-298.69). Pooled pain outcomes from two studies showed that 28/30, 93% (95% CI = 93-100%), experienced ≥50% pain improvement at three months.ConclusionsThe literature supporting the effectiveness of PRP for SIJC pain is very low-quality according to the GRADE system. Well-designed RCTs and large cohort studies with consistent selection protocols and reporting characteristics are needed to determine the effectiveness of PRP and BMAC for the treatment of SIJC pain.© The Author(s) 2020.
