Abstract | Purpose: Methods: PubMed, Ovid MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews were reviewed by 2 independent reviewers for eligible studies. We included randomized and nonrandomized control trials as well as uncontrolled case series and retrospective studies. Studies were excluded if they included injections of corticosteroids, papers that described technique only, review papers, and those not in the English language. Demographics, treatment type, outcome of treatment, and complications were extracted, whereas risk of bias and study quality were assessed independently using the risk of bias tool (ROB2) and effective public health practice project tool. A narrative synthesis was performed, and standardized mean differences were reported. Certainty of evidence was assessed using the GRADE approach. Results: Eighteen studies consisting of 1,024 patients met the inclusion criteria. Three studies involved the use of platelet-rich plasma (PRP) as an adjuvant to surgery and were included in the meta-analysis. Three studies administered hyaluronic acid (HA) as a primary treatment. Twelve involved various cell-based methods of chondrocyte stimulation for cartilage defects associated with FAI, but heterogeneity did not allow for pooling. Low-quality evidence indicates PRP is not associated with improved outcomes following surgery (mean difference -1.42, 95% confidence interval -3.95 to 1.11, P = .27). Very-low-quality evidence suggests HA (standardized mean difference 1.15, 95% confidence interval 0.64-1.66, P < .001, Z = 4.39) and cell-based therapies may improve function and pain in patients with FAI. Conclusions: Low-quality evidence indicates PRP is not associated with improved outcomes following hip FAI surgery, and very-low-quality evidence suggests HA and cell-based therapies may improve outcomes. Level of Evidence: systematic review of Level I-V studies.
