Baxter's Nerve Pulsed Radiofrequency Versus Platelet-Rich Plasma Injection or Both Together as a Treatment Modality of Recalcitrant Plantar Fasciitis

Plantar fasciitis is a common condition causing chronic heel pain due to degenerative changes in the tissue supporting the arch of the foot. While most patients improve with conservative care such as physical therapy, anti-inflammatory medications, and orthotics, approximately 10% to 20% experience chronic pain that fails to respond to standard measures. In up to 20% of these persistent cases, irritation or entrapment of the first branch of the lateral plantar nerve (Baxter's nerve) also plays a key role in the pain. The purpose of this study is to compare the safety and effectiveness of three ultrasound-guided interventional approaches for treating chronic recalcitrant plantar fasciitis: 1. Baxter's nerve pulsed radiofrequency (PRF), a neuromodulation procedure designed to reduce nerve-related pain without destroying nerve fibers. 2. Platelet-rich plasma (PRP) injection, an autologous blood-derived preparation that delivers natural growth factors to stimulate tissue healing and repair of the plantar fascia. 3. Combined PRF and PRP therapy, addressing both nerve irritation and structural tissue degeneration simultaneously. A total of 75 adult patients aged 18 to 65 years with recalcitrant plantar fasciitis persisting for over 6 months will be randomly assigned into three equal groups (25 patients per group). Participants and independent clinical assessors will be blinded to treatment allocation. Patients will be followed for 6 months to evaluate pain reduction, functional recovery, plantar fascia thickness measured by ultrasound, and procedure safety.
