The Achilles is the largest tendon in the body, and when it becomes painful it can sideline runners, athletes, and everyday walkers alike. Some Achilles problems are acute; many are chronic, involving gradual degeneration of the tendon. For those persistent cases, PRP is one regenerative option worth understanding.
Acute vs. chronic Achilles problems
Achilles pain isn’t one condition. A sudden injury or rupture is very different from chronic tendinosis, where the tendon slowly degenerates from overuse. PRP is generally discussed for certain chronic, degenerative cases — not for acute ruptures, which are managed differently. Our Achilles tendonitis page covers the basics.
How PRP may help the Achilles
Chronic tendon tissue heals slowly because of limited blood supply. PRP concentrates growth factors from your own blood and delivers them to the injured area, aiming to stimulate a healing response in tissue that has stalled. You can read the full explanation on our PRP page.
When is it considered?
PRP for the Achilles is typically a later step, after conservative measures such as eccentric strengthening exercises, activity modification, heel support, and physical therapy have had a fair trial. If chronic pain persists despite those efforts, PRP may be one option to consider based on your exam and imaging.
What the treatment is like
Blood is drawn and spun to prepare the PRP, which is then injected into the affected part of the tendon, often with imaging guidance for accuracy. Expect some soreness afterward and a period of modified activity, followed by a guided return to loading the tendon. Rehab exercises usually continue alongside the treatment.
Setting realistic expectations
Evidence for PRP in Achilles tendinosis is mixed, and it doesn’t help everyone. It works best as part of a comprehensive plan that includes the loading and strengthening work the tendon needs. Your podiatrist should be candid about whether it’s a reasonable option for your specific case.
Frequently Asked Questions
Is PRP used for a torn Achilles?
PRP is generally discussed for chronic degenerative tendon problems, not acute ruptures, which are managed with other approaches.
How long is recovery after PRP for the Achilles?
You can expect soreness for a few days and a guided return to activity over weeks, usually alongside rehab exercises. Timelines vary.
Does PRP replace Achilles surgery?
Not necessarily. For some chronic cases it’s a non-surgical option to try first, but certain problems still require surgery.
