To Evaluate Efficacy of Intralesional Platelet Rich Plasma in Patients with Plantar Fasciitis.

Abstract

Background: Plantar fasciitis (PF) is one of the most common causes of heel pain that affecting 10 % of the general population. Platelet rich plasma (PRP) has been demonstrated to be helpful in managing PF and reducing plantar facia thickness (PFT). This study objective was to know the effect and efficacy of ultrasound (USG) guided intralesional PRP in PF in relation to pain, PFT and foot function index (FFI).

Methods: A prospective interventional study was conducted in a tertiary care hospital on eighty-five diagnosed cases of unilateral PF. All patients had undergone pain intensity assessment by visual analogue scale (VAS), FFI, and USG examination of PFT after USG guided intralesional PRP injection was assessed at baseline (0 weeks), 2 weeks and 6 weeks.

Results: Following USG guided intralesional PRP injection, a statistically significant decrease was noted in plantar fascia thickness (PFT) from baseline 0 (week) 6.592mm ± 0.51mm to 5.169mm ± 0.39mm and reduced to 4.07mm ± 0.39mm at 2nd week and 6th week, respectively (P value < 0.001). A statistically significant reduction of VAS score was noted which reduced from 8.647 ± 0.55 to 5.588 ± 1.13 (2nd week) and further reduced to 1.21 ± 1.06 at the end of 6 weeks (p value < 0.001). Mean FFI in our study at baseline was 85.494 ± 6.55, at 2 weeks mean FFI was 49.341 ± 7.277 and the end of 6 week it reduced to 24.235 ± 1.608 (P value < 0.001) statistically significant decrease was noted.

Conclusions: PRP injection helps in the reduction of heel pain (VAS), reduction in PFT, and improvement in all domains of FFI, leading to enhancement of quality of life.
