Quick answer: PRP has been studied for chronic plantar fasciitis that has not improved with conservative care. Randomized-trial meta-analyses suggest that PRP can provide outcomes comparable to other injection approaches and may show greater benefit at longer follow-up in some studies, but results are inconsistent and PRP is not the first treatment for most patients.
What is plantar fasciitis?
Plantar fasciitis commonly causes heel pain that is worst with the first steps after rest or prolonged standing. Symptoms can overlap with nerve entrapment, stress injury, fat-pad problems, Achilles disorders, and other causes, so the diagnosis should be confirmed before an injection.
When might PRP be discussed?
PRP is generally considered after appropriate conservative management such as footwear modification, stretching, load management, physical therapy, and other standard treatments have been tried.
What does the research show?
Meta-analyses of randomized trials have found that PRP can improve pain and function in chronic plantar fasciitis, with some studies suggesting longer-term benefit compared with corticosteroid injection. The literature remains heterogeneous, so a guaranteed outcome should not be promised.
What else should be part of treatment?
Calf flexibility, foot mechanics, activity load, body weight when relevant, footwear, and rehabilitation can all affect recovery. PRP does not replace these factors.
