Platelet-Rich Plasma For Plantar Fasciitis

Platelet-rich plasma for plantar fasciitis

The plantar fascia is a thick band of ligamentous tissue on the bottom of the foot connecting the heel to the ball of the foot. When the plantar fascia is stressed over time it can become weakened and damaged. Despite being called an “itis” plantar fasciitis is suspected to not be caused by an inflammatory process but instead by a gradual degeneration of the plantar fascia1. Platelet-rich plasma (PRP) offers hope for people with plantar fasciitis as it can significantly reduce their pain and improve their mobility.

How Does Platelet-Rich Plasma Work?

The effectiveness of PRP is due to growth factors which are naturally present in platelets. The high concentration of platelets within PRP carry a large amount of growth factors. These growth factors are directly introduced to the site of injury during a PRP injection and jump-start the healing process. These growth factors include platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-β), insulin-like growth factor (IGF), epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF)2.

Excellent Results For Plantar Fasciitis

The research clearly shows that PRP has a beneficial effect on plantar fasciitis. In total 20 studies have been performed on PRP for plantar fasciitis. All 20 of these studies have found that people being treated with PRP have significant improvements in the pain associated with their plantar fasciitis3-22. In the 9 studies comparing PRP treatment to corticosteroid injections 6 of these studies found that PRP was a superior treatment3-8, 1 of these studies found PRP to be as good or better9 and and 2 of these studies found that PRP was equally as good as a corticosteroid injection10,11.

PRP ResearchVs. Cortisone InjectionFindings
Vahdatpour 20163Superior to cortisone“… Because of this long-term effect of PRP, its use is more preferred than corticosteroid in plantar fasciitis.”
Jain 20154Superior to cortisone“At 12 months, PRP is significantly more effective than Steroid, making it better and more durable than cortisone injection.”
Say 20145Superior to cortisone“The application of PRP appears to be more effective than steroid injection in terms of pain and functional results in the treatment of chronic plantar fasciitis.”
Shetty 20146Superior to cortisone“Our study confirms that there is significant clinical improvement in PRP group at three months after the injection.”
Monto 20147Superior to cortisone“PRP was more effective and durable than cortisone injection for the treatment of chronic recalcitrant cases of plantar fasciitis.”
Tiwari 20138Superior to cortisone“The results at the 1, 3 & 6 months were evaluated, which showed the good results with platelet rich plasma in comparison to steroid injections.”
Mahindra 20169As or more effective“Platelet-rich plasma injection is as effective as or more effective than corticosteroid injection in treating chronic plantar fasciitis.”
Acosta-Olivo 201610Equally effective“… PRP demonstrates an efficacy equal to that of steroids.”
Akşahin 201211Equally effective“PRP injection seems to be safer and at least having same effectivity in the treatment of plantar fasciitis.”

The favourability of PRP over corticosteroid injections has also been noted because of the possible adverse effects of corticosteroid injections including adverse structural tendon changes, heel fat pad degeneration and, most worryingly, plantar fascia rupture23,24.

How Platelet-Rich Plasma Is Prepared

Platelet-rich plasma treatment

PRP is prepared by collecting and centrifuging a sample of a person’s own blood on the day of treatment. PRP is not stored for later use as new blood can easily be collected prior to treatment ensuring maximum safety. The centrifuging process rotates the blood rapidly causing the components of the blood to separate according to their weight. Platelets, being a different weight than other blood components, separate into their own layer separate from the lower red blood cell layer and higher plasma layer. These platelets are the part of the blood which is collected and used for injection.

What To Expect

Some people who receive PRP treatment for plantar fasciitis may have additional discomfort after the injection for a day or two. Improvement may be seen in the pain and disability associated with plantar fasciitis within the first few weeks. Although improvement often can be seen after one injection two or three injections typically yield optimal results.


PRP is exceptionally safe because it simply uses a component of the blood of the person being treated. The risk of allergy or other reactions are essentially absent as a result. The studies which have investigated PRP have also found an excellent safety profile25.
