The treatment of intractable plantar fasciitis with platelet-rich plasma injection

Foot (Edinb). Jun-Sep 2013;23(2-3):74-7. doi: 10.1016/j.foot.2013.06.002. Epub 2013 Jul 30.


Background: Whilst most cases of plantar fasciitis can be settled with existing conservative treatment, a few intractable cases can be difficult to resolve. New biologic treatments have been proposed for a variety of soft tissue problems.

Objective: Evaluate the effectiveness of platelet rich plasma (PRP) in chronic cases of plantar fasciitis.

Patients and methods: Patients with plantar fasciitis not responded to a minimum of 1 year standard conservative management were offered PRP therapy. Injections were performed in theatre as a day case. Roles-Maudsley (RM) scores, Visual Analogue Scores (VAS), AOFAS scores and 'would have injection again' were collated pre-operatively, three and six months.

Results: Prospective data was collected of 50 heels (44 patients). At six month review, RM score improved from mean 4 to 2 (p<0.001), VAS improved from 7.7 to 4.2 (p<0.001) and AOFAS improved from 60.6 to 81.9 (p<0.001). 28 patients (64%) were very satisfied and would have the injection again. No complications were reported.

Conclusion: In these chronic cases, PRP produce an efficacy rate, approaching 2 out of every 3. The procedure was safe with no reported complications. The authors feel PRP may have some role in treatment, and merits further study with a prospective randomised trial.
