Background:
Plantar fasciitis (PF) is a common foot disorder with variability in treatment strategy. Two effective management techniques include platelet-rich plasma (PRP) injections and extracorporeal shock wave therapy (ESWT). The purpose of this meta-analysis is to compare the effectiveness of PRP vs ESWT in the management of PF.
Methods:
A systematic search was performed of PubMed, Cochrane, and Google Scholar for randomized controlled trials comparing PRP to ESWT. Studies met inclusion criteria if mean and SDs for visual analog scale (VAS) pain scores and plantar fascia thickness (PFT) were reported. Mean differences were used to compare VAS pain score and PFT between PRP and ESWT.
Results:
Six randomized controlled trials, comparing a total of 214 subjects in the PRP group and 218 subjects in the ESWT group, were analyzed. A significantly greater statistical improvement was seen in the PRP group in VAS pain (mean difference = -0.67 [95% CI -1.16, -0.18], P = .007) and plantar fascia thickness (PFT) (mean difference = -0.56 [95% CI -0.77, -0.35], P < .001).
Conclusion:
PRP had a statistically higher pain reduction than ESWT, but the difference does not reach clinical significance in this meta-analysis.
