OJECTIVE– The purpose of this study was to evaluate efficacy of autologous platelet–rich plasma injection in case of proximal plantar fascitis which have failed conservative management.

MATERIALS AND METHODS– Fifty patients((total heels 62)) proximal plantar fascitis who have failed to improve even after three months of conservative management, of unilateral and bilateral affected heels receiving  one time  injections of autologous PRP into the plantar fascia were assessed 1,3,and 6 months follow up after the procedure. The visual analogue scale (VAS) for pain and American Orthopaedic Foot and Ankle Society (AOFAS) Ankle and Hind foot score were used to evaluate the clinical results.

RESULTS– Basis of Visual analogue pain score and AOFAS ankle and hind foot score satisfactory improvement of pain at 1 month, 3 months and 6 month post injection were observed in 22.6%, 45.2%, 75.8% and 21%, 45.2% and 75.2% of heels, respectively.

Pain was significantly decreased on basis of VAS from 7.92 to 6.29, 3.81, 2.6 and on basis of AOFAS from pre–ejection sore 66 to 73.42, 84.69, 89.23 at 1, 3, and 6 month follow up.

CONCLUSION:  In this single–center, uncontrolled, prospective, preliminary study indicates that PRP injection has a role to play in the management of chronic intractable proximal plantar fascitis. This technique was efficient in approach 75% affected heels at 6 month follow–up, and injection no associated with any complication.
