Abstract Purpose The purpose of this study was to assess the safety and preliminary clinical results of platelet-rich plasma (PRP) injections for treating chronic plantar fasciitis. Methods Fourteen consecutive patients with chronic plantar fasciitis receiving three injections of PRP into the plantar fascia were assessed 12 months after the procedure. The modified Roles and Maudsley score and a visual analogue scale (VAS) for pain were used to evaluate the clinical results. Results According to criteria of the Roles and Maudsley score, at 12 months of follow-up, results were rated as excellent in nine (64.3 %), good in two (14.3 %), acceptable in two (14.3 %) and poor in one (7.1 %) patient. VAS for pain was significantly decreased from 7.1±1.1 before treatment to 1.9±1.5 at the last follow-up (pone hour), acceptable (symptoms somewhat decreased, pain at a more tolerable level than before treatment and patient slightly satisfied with the treatment outcome) or poor (symptoms identical or worse and patient not satisfied with the treatment outcome). Treatment was considered successful when the patient had an excellent or good score. Patients were examined clinically at 12 months after the index procedure. Data were analyzed using SPSS 13.0 (SPSS Inc., Chicago, IL, USA), with a paired t test after checking normal distribution of samples with the Kolmogorov–Smirnoff z test. The level of significance was considered as p
