Introduction: Plantar fasciitis accounts for 15% of all foot disorders affecting 10% of world population.PF causes are not clearly known but it is most probably started by overuse injury. Most commonly presents with symptom of acute, insidious onset of pain with maximum sensitivity near the anterior midline of calcaneus.Many methods are advocated to treat PF, which includes rest, NSAIDs, splints during night, foot orthosis, stretching protocols, and ESW therapy.Locally injected steroids have traditionally been widely used to treat chronic plantar fasciitis. Recently Platelet-rich plasma (PRP) has been successfully used to treat a variety of chronic tendonitis, including chronic Planter fasciitis. Materials and Methods:Hundred patients were studied between 2019 and 2021. Patients were randomized in 2 groups. Group 1: patients were given a single 3 mL autologous PRP injection through local injection.Group 2: The patients received one 3 cc dose of 80 mg of methylprednisolone acetate locally and followed up at 6 weeks, 3rd and 6 months. Pain and functional outcome assessment was done using visual analog scale (VAS) and American Orthopedic Foot and Ankle Society (AOFAS) score. Results: Mean VAS reduced from 7.24 before injection to 1.42 after injection in Group 1, and from 7.31 before injection to 3.64 after injection in Group 2, at final follow-up. At 6 months' follow-up, the mean AOFAS score for Group 1 improved from 56.2 to 89.65 and for Group 2 from 55.13 to 75.63. There was a statistically significant improvement in VAS and AOFAS. A statistically significant difference was observed in plantar fascia thickness between groups at six months (5.86 mm to 3.46 mm in Group 1 and 5.74 to 3.83 mm in Group 2). Conclusion: Compared to steroid injections, injections of platelet-rich plasma have a longer-lasting beneficial effect than local injections of steroid.
