Positive Effect of Platelet-Rich Plasma on Pain in Plantar Fasciitis: A Double-Blind Multicenter Randomized Controlled Trial.

Background: When nonoperative treatment for chronic plantar fasciitis fails, often a corticosteroid injection is given. Corticosteroid injection gives temporary pain reduction but no healing. Platelet-rich plasma (PRP) has proven to be a safe therapeutic option in the treatment of tendon, muscle, bone, and cartilage injuries.
