Effectiveness of Platelet-rich Plasma Injections for Plantar Fasciitis: A Patient Reported Outcomes Evaluation

Abstract

Category: Other Introduction/Purpose: Steroid injection is a common treatment for Plantar fasciitis (PF) but has high recurrence rates. Platelet- rich plasma (PRP) injections have been used as an alternative treatment. Our aim was to review the effectiveness of PRP injection. Methods: All patients who underwent PRP injection for PF between 2015 and 2021 were included in this study. Clinical results and patient reported outcomes (MOX-FQ scores, EQ-5D and FAOS scores) were collected pre and post-operatively. Results: A total of 34 patients underwent PRP injection between 2015 and 2021 (mean age 34 years). There was a 71% PROMs response rate (80% female with, mean age 53). The mean duration of symptoms was 4 years and the median follow up time was 4.2 years. 77.1% were satisfied with overall outcomes of treatment with PRP injections (p < 0.05). 68.1% of patients reported satisfaction with pain relief. 74.6% were satisfied with return to activities of daily living. 72.6% were satisfied with return to recreational activities. 59% reported improvement in quality-of-life post treatment. 64% were happy to receive the same treatment again; 13.6% would not have the procedure again. 2 patients had severe pain within 2 weeks following the injection but symptoms settled. No other complications. Conclusion: PF is considered to be a self-limiting condition but can be debilitating whilst awaiting resolution of symptoms which can take upwards of 12 months to fully resolve. PRP injection provides effective pain relief for PF at 4 years follow up.
