PRP for Plantar Fasciitis and Heel Pain: What the Research Shows

What plantar fasciitis actually is

Plantar fasciitis is irritation of the thick band of tissue, the plantar fascia, that runs across the bottom of the foot and connects the heel bone to the toes. It typically shows up as a sharp heel pain with the first steps in the morning or after rest, easing somewhat as the tissue warms up. Repetitive strain, tight calf muscles, sudden increases in running or walking, and long hours standing are common contributors, and Hawaii's mix of hiking trails, beach walking in sand, and everyday wear can all feed into it.

When conservative care is not enough

Most cases of plantar fasciitis improve with a consistent program of calf stretching, proper footwear, activity modification, and sometimes orthotics or physical therapy. When that approach has been tried faithfully for several months and pain persists, providers may discuss further options, including injections. That is typically the point where regenerative treatments like PRP enter the conversation.

What the recent research shows

The evidence base for PRP in plantar fasciitis has grown meaningfully in recent years. A 2025 systematic review and meta-analysis of 24 randomized controlled trials including over 1,600 patients, published in the American Journal of Physical Medicine & Rehabilitation, found that PRP provided significantly better pain relief and foot function than corticosteroid injections at 3-,6-,and 12-month follow-up. Other 2024 meta-analyses similarly report that PRP reduces pain more effectively than extracorporeal shockwave therapy over longer follow-up periods.

“In a 2025 systematic review and meta-analysis of 24 randomized controlled trials including 1,653 patients, investigators found that platelet-rich plasma yielded significantly better pain relief than corticosteroid injections over several months of follow-up.”

What this means in plain terms: corticosteroids can provide quicker short-term relief, but that effect tends to fade, while PRP's benefit appears more durable over months. That distinction is why many foot and ankle specialists now discuss PRP for chronic plantar fasciitis that has not settled rather than repeating steroid injections.

Who is typically a candidate

• Chronic heel pain that has persisted despite several months of stretching, footwear changes, and activity modification
• Plantar fasciitis confirmed by a clinical exam, often with imaging such as ultrasound or MRI
• No sign of acute infection, fracture, or another problem that needs different care
• Patients who understand that PRP is support for healing, not a guaranteed cure

What a PRP visit here involves

At Aloha Stem Cell, a PRP consultation starts with a conversation and a focused exam of your foot and ankle. If imaging is needed, the team will explain why. The treatment itself uses your own blood, drawn at the clinic, spun in a centrifuge, and injected into the painful area under local numbing, typically within a single outpatient visit.

Because Dr. Robert Aki, DPM, brings foot and ankle surgical expertise to the clinical team, heel pain is an area where patients get a thorough, specialist-informed evaluation. After the injection, you leave with a recovery plan, follow-up guidance, and a number to call with questions.

Questions worth asking

• How long have I already tried conservative care, and what exactly did it include?
• What imaging do I need before treatment?
• Is my heel pain really plantar fasciitis, or could it be something else, like a plantar fascia tear or nerve irritation?
• What does the evidence show for my situation, and what are the realistic timelines?
• What will recovery look like, and when can I get back to running or hiking?
