Background: Intralesional injection of autologous blood-derived products has recently gained attention as a potential treatment for plantar fasciitis (PF). We compared platelet-rich plasma (PRP) and whole blood (WB) for the treatment of chronic PF.
Materials and Methods: Patients with chronic PF received either an intralesional injection of 3 cc PRP prepared by double centrifuge technique or WB (n = 17 in each group). Overall, morning and walking pain severity were assessed by 11-point numerical rating scale, and function was assessed by the Roles and Maudsley score (RMS) at baseline and 1-month and 3 months after treatment. Ultrasonography was performed to measure plantar fascia thickness at baseline and 3 months after treatment.

Results: Pain scores were reduced over the study in the PRP (mean change = −5.00 ± 1.17 to −5.47 ± 1.46) and WB groups (mean change = −5.29 ± 2.56 to −6.47 ± 2.83), with no difference between groups (P > 0.05). One month and 3 months after treatment, successful treatment (RMS of ≤ 2) was respectively observed in 29.4% and 82.3% of the PRP and in 47.1% and 76.4% of the WB groups (P > 0.05). Also, fascia thickness was decreased in both the PRP and WB groups (mean change = −1.74 ± 1.11 vs. −1.21 ± 0.73 mm, respectively, P = 0.115).
Conclusions: Significant improvement in pain and function, as well as decrease in plantar fascia thickness, was observed by intralesional injection of the PRP and WB in patients with chronic PF. The study results indicate similar effectiveness between PRP and WB for the treatment of chronic PF in short-term.
