PRP for Achilles Tendinopathy: What the Evidence Shows

The strongest evidence to date, including a large placebo-controlled trial and multiple recent meta-analyses, does not show that PRP injections are more effective than sham dry-needle injections for chronic midportion Achilles tendinopathy. Symptoms often improve substantially over 6 to 12 months with exercise-based care, with or without an injection, which is why the role of PRP for this specific condition remains uncertain. At Zest Regen Health in Columbia, Maryland, PRP is considered only after a medical evaluation determines it may be appropriate for your specific presentation, and for many patients a structured rehabilitation program is the recommended first step.

What the evidence shows

The largest trial to date, published in JAMA in 2021, randomized 240 patients with chronic midportion Achilles tendinopathy to a single PRP injection or a sham (dry-needle) injection. It found no significant difference in Achilles tendon function between the two groups at six months.

Recent meta-analyses of randomized controlled trials have reached the same conclusion. A 2025 meta-analysis in Clinical Orthopaedics and Related Research pooled six trials and found no benefit of PRP over placebo on the VISA-A score, the standard tendon function measure, at three months, six months, or one year. A 2024 meta-analysis in Sports Health also found no significant difference in VISA-A at any time point, and a 2026 meta-analysis in the Journal of Foot and Ankle Surgery reported no significant clinical benefit at three and six months.

Why the evidence matters

Achilles tendinopathy is a useful example of why a treatment can sound promising and still fail to beat a placebo in careful trials. The condition improves on its own in many patients, so improvements are easily attributed to an injection even when it contributed little. That does not mean PRP never helps anyone; it means the overall evidence does not currently support offering it as a routine treatment for this specific problem.

What usually comes first

• A structured exercise or rehabilitation program sustained over several months, because loading and strengthening programs have the strongest evidence base
• Activity modification and a footwear review when relevant
• An assessment of strength, range of motion, and biomechanics by a clinician
• A conversation about whether any injection, including PRP, is worth considering after rehabilitation has been tried

Who may be a candidate for PRP

There are patients for whom a clinician may reasonably consider PRP, such as those who have not improved after a full course of rehabilitation and who understand the uncertainty in the evidence. Candidacy at Zest Regen Health is decided individually after a medical evaluation that includes history, examination, and review of relevant imaging. PRP is not a guarantee, and results vary from person to person.

What an evaluation at the clinic involves

1. A discussion of your history, activity level, and what you have tried so far
2. A physical examination of the Achilles tendon and lower leg
3. Review of any imaging you have
4. A plain-language explanation of the evidence and your realistic options

What to keep in mind

The Achilles tendon is one of the strongest tendons in the body, but it is also a common site of overuse injury, especially for runners and active adults in Howard County and the surrounding area. Pain that lingers for months deserves an evaluation rather than repeated injections without a plan, and the right next step depends on the specific problem rather than a menu of procedures.

Next step

If Achilles pain has limited running, walking, or daily activity for more than a few weeks, start with an evaluation rather than a decision between injections.
