Abstract

Objective The aim of this study was to determine the efficacy of local platelet-rich plasma (PRP) injection compared with extracorporeal shock-wave therapy (ESWT) for treatment of plantar fasciitis. Background Plantar fasciitis is an important cause of heel pain. ESWT and PRP have emerged as new management options, alternative for surgery. Patients and methods This comparative study included 60 patients, comprising 48 female and 12 male patients with plantar fasciitis diagnosed clinically and by ultrasound. The patients were divided into two groups: 30 patients received single local PRP injection and 30 patients received three sessions of ESWT weekly. All patients were assessed using pain visual analog scale (VAS) score, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hind foot scale, and plantar fascia thickness by ultrasound before treatment and at 1 and 3 months after treatment. Results VAS, AOFAS ankle-hind foot score, and plantar fascia thickness improved significantly in both groups. The AOFAS ankle-hind foot scale shows more improvement in the ESWT group at 1 month after treatment (P = 0.009). Significant improvement in plantar fascia thickness was seen clearly in PRP group at 1 and 3 months after treatment (P < 0.001). VAS and AOFAS ankle-hind foot scale score in patients with calcaneal spur show more improvement in ESWT group at 1 month after treatment (P = 0.019 and P = 0.009, respectively). Conclusion Local PRP injection and ESWT improve pain and function in patients with plantar fasciitis. ESWT showed early improvement if plantar fasciitis is associated with calcaneal spur.
