Treatment of Chronic Plantar Fasciitis with Ultrasound-Guided Injection of Platelets Rich Plasma

Abstract


Background: Plantar fasciitis (PF) is one of the common reasons of heel pain that making up 11% - 15% professional managements for the foot symptoms among adults.

Objectives: The current study aimed to compare the effect of ultrasound-guided (US-guided) injection of platelets rich plasma (PRP) with that of corticosteroid injection to treat patients with chronic PF.

Methods: Patients with PF (n = 30) were assigned to receive either PRP or corticosteroid US-guided injection. The pain level was evaluated by the visual analogue scale (VAS) the baseline, three and eight weeks after injection. Disabilities were assessed by foot and ankle ability measure (FAAM) at the baseline, three and eight weeks after injection.

Results: In both corticosteroid and PRP injected groups, the average VAS heel pain scores and the mean FAAM subscales scores were statistically lower compared with the pre-treatment scores (P < 0.001). The improving symptoms in the corticosteroid group at the beginning (after three weeks) were better and then decreased after eight weeks, but the differences were not significant; while in the PRP group symptoms progressively improved.

Conclusions: The current study results revealed that both methods were effective and successful to treat PF, but due to potential complication of corticosteroid and its short-term relief of pain, PRP injection looked safer.
