Analgesic efficacy and functional outcome in refractory cases of plantar fasciitis treated with platelet-rich plasma: randomized comparative study with corticosteroids injection

Authors

Abstract

Background
Steroid injection is a widespread treatment for plantar fasciitis but seems to be useful to a lesser extent, Platelet-rich Plasma (PRP) injections into the plantar fascia start the healing process required to stop the degeneration of the plantar fascia at its root.
Aim of the study
To compare analgesic efficacy, functional outcome, degree of satisfaction and improvement of fascial thickness and echogenicity after platelet-rich plasma injection versus corticosteroids injection in refractory cases of plantar fasciitis.
Patients & method
60 patients with refractory plantar fasciitis who were resistant to conservative treatment were randomized to receive either PRP or steroid injection. All patients were assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) score, Visual Analogue Score (VAS) for pain, the Roles-Maudsley (RM) Score and plantar fascia thickness and echogenicity. Data were collected prospectively, pre-treatment, at 3, 6, 12 week, and 6 months post-injection.
Results
There was significant improvement in both groups as regards the clinical outcome measures involving (VAS & AOFAS) and radiological outcome measures including (thickness and echogenicity) in all post-injection times. However, steroid group showed early improvement (at 3rd week post-injection) with short duration while PRP group showed improvement at 12 weeks post-injection till the end of the study.
Conclusion
The use of PRP injection is safer with better analgesia and functional outcome than steroid therapy for treating chronic plantar fasciitis.
