Baxter's Nerve Pulsed Radiofrequency Versus Platelet-Rich Plasma Injection or Both Together as a Treatment Modality of Recalcitrant Plantar Fasciitis
Baxter's Nerve Pulsed Radiofrequency Versus Platelet-Rich Plasma Injection or Both Together as a Treatment Modality of Recalcitrant Plantar Fasciitis: Randomized Controlled Trial
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:
- Baxter's nerve pulsed radiofrequency (PRF), a neuromodulation procedure designed to reduce nerve-related pain without destroying nerve fibers.
- 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.
- 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.

|---|---|
|
Experimental: Group A: Baxter's Nerve Pulsed Radiofrequency
Participants receive ultrasound-guided pulsed radiofrequency (PRF) targeting Baxter's nerve (the first branch of the lateral plantar nerve).
The procedure is performed under complete aseptic technique at 42°C, with a pulse width of 20 ms, a frequency of 2 Hz, for a duration of 8 minutes.
|
Ultrasound-guided pulsed radiofrequency (PRF) targeting Baxter's nerve (the first branch of the lateral plantar nerve) performed under sterile aseptic precautions.
Parameters applied: target temperature of 42°C, pulse width of 20 ms, frequency of 2 Hz, for a total duration of 8 minutes.
|
|
Comparador Ativo: Group B: Platelet-Rich Plasma Injection
Participants receive an ultrasound-guided injection of 5 mL autologous platelet-rich plasma (PRP) into the diseased plantar fascia.
PRP is prepared via a standardized double-spin centrifugation technique and administered under complete aseptic precautions.
|
Ultrasound-guided administration of 5 mL autologous platelet-rich plasma (PRP) directly into the hypoechoic, thickened portion of the diseased plantar fascia.
PRP is isolated using a standardized double-spin centrifugation protocol and injected under complete aseptic conditions.
|
|
Experimental: Group C: Combined PRF and PRP Therapy
Participants receive combined treatment consisting of ultrasound-guided Baxter's nerve pulsed radiofrequency (42°C, 20 ms pulse width, 2 Hz for 8 minutes) followed by ultrasound-guided autologous platelet-rich plasma injection (5 mL) into the diseased plantar fascia under complete aseptic technique.

Change from Baseline in Visual Analogue Scale (VAS) Pain Score
Prazo: Baseline and 6 months post-intervention
|
Pain intensity is assessed using the Visual Analogue Scale (VAS), where patients rate their heel pain on a 0 to 10 scale (0 = no pain, 10 = worst imaginable pain).
Lower scores indicate less pain and better clinical improvement.
The score change will be calculated as the post-treatment score minus the baseline score.
