<p class="abstract"><strong>Background:</strong> Plantar fasciitis is a common pathological condition affecting the hind foot, and a common cause of heel pain. The present study was taken up to assess the efficacy of intralesional corticosteroid compared to autologous platelet rich plasma injection in the management of chronic plantar fasciitis.</p><p class="abstract"><strong>Methods:</strong> Patients were randomized into two groups (Group A and Group B) of 30 each. Group-A received Corticosteroid injection while Group-B received PRP injection. Patients were assessed functionally using American Orthopaedic Foot and ankle score (AOFAS), Visual analogue scale (VAS) scores before treatment and on follow-up visit at 6 weeks, 3rd month, and 6th month. Ultrasound of heel for plantar fascia thickness was measured before treatment and follow up visit at 6th month.<strong></strong></p><p class="abstract"><strong>Results:</strong> A significant decrease in VAS score was observed in the corticosteroid group compared to PRP group at 6 weeks while the VAS score continued to decrease in the PRP group at 3 months and 6 months with an increase in the corticosteroid group at 3 months and 6 months. A significant increase in AOFAS was observed in the Corticosteroid group compared to PRP group at 6 weeks which increased in the PRP group at 3 months and 6 months. However it decreased in the corticosteroid group at 3 months and 6 months. Ultrasonographic evaluation showed improvement in fascial thickness in both the groups, but was better in the PRP group.</p><p class="abstract"><strong>Conclusions:</strong> To conclude our study shows that corticosteroid is more effective for short term relief and PRP is more effective for long term relief.</p>
