This single center prospective pilot randomized controlled trial investigates the comparative efficacy of three interventional modalities for the management of chronic plantar fasciitis: ultrasound guided platelet rich plasma PRP injections into the plantar fascia, PRP injections combined with ultrasound guided Baxters nerve block targeting the first branch of the lateral plantar nerve, and ultrasound guided corticosteroid methylprednisolone injections with lignocaine. A total of 45 adult patients aged 18 years and above with clinically diagnosed and ultrasonographically confirmed plantar fasciitis with fascia thickness greater than 4 mm refractory to conservative therapy will be randomized equally into three parallel groups. All participants will continue to receive standardized conservative management. The primary endpoints include changes in pain intensity measured using the Numeric Rating Scale NRS and plantar fascia thickness assessed via high resolution ultrasonography at baseline, 6 weeks, and 12 weeks. Secondary endpoints include functional outcomes assessed by the Foot and Ankle Disability Index FADI, patient satisfaction measured via a structured questionnaire at 12 weeks, and documentation of any adverse events. Statistical analysis will involve repeated measures ANOVA, t tests, or nonparametric equivalents with significance set at p less than 005. The primary aim is to determine whether combining Baxters nerve block with PRP provides superior analgesic and functional benefits compared to PRP alone or corticosteroid injections.
