Plantar Fascia Embolization for the Treatment of Chronic Plantar Fasciitis: A Critical Appraisal of Limited Evidence

Background: Plantar fascia embolization (PFE) has emerged as a minimally invasive intervention for patients with chronic plantar fasciitis. Increasing visibility of this procedure has led to growing patient and clinician interest despite a limited evidentiary foundation. Methods: A critical review of the available literature was performed to evaluate the quality of evidence, patient selection criteria, procedural variability, reported outcomes, and clinical applicability of PFE. Results: Current evidence is limited to small, uncontrolled observational studies. While improvements in pain and function have been reported, consistent limitations include a lack of standardized diagnostic criteria, the absence of comparator groups, variability in prior conservative treatment, non-blinded outcome assessment, and incomplete biomechanical characterization. Conclusions: Although early findings are encouraging, the current evidence base is insufficient to define the efficacy, safety, or appropriate clinical role of PFE. At present, this intervention should be considered investigational, and further study using standardized diagnostic and treatment frameworks is required.
