If you've been dealing with Achilles tendon pain that just won't go away — the morning stiffness, the burning ache above your heel after a run, the tightness that limits your daily walks — you know how frustrating it feels to be told to "just rest and stretch." For many patients in Bethesda, McLean, and the wider DC metro area, conventional treatments provide only temporary relief. That's where PRP injection for Achilles tendinopathy comes in.
Platelet-rich plasma (PRP) therapy is a regenerative medicine treatment that harnesses your body's own healing proteins to repair damaged tendon tissue — not just manage the pain. At DD Podiatry, with offices in Bethesda, MD and McLean, VA, Drs. Nam Tran and Miriam Niktash have helped hundreds of patients recover from chronic Achilles tendon problems using this advanced, minimally invasive approach.
In this guide, we'll walk you through exactly what PRP is, how it works for Achilles tendinopathy, who makes the best candidate, and what you can expect from treatment at our practice.
The Achilles tendon is the thickest, strongest tendon in your body — connecting your calf muscles to your heel bone. It absorbs tremendous force with every step, especially during running, jumping, and climbing stairs. That's why, when it becomes damaged or degenerative, it can feel like your entire foundation is compromised.
Achilles tendinopathy is an umbrella term for painful, degenerative changes in the Achilles tendon. It includes:
What makes the Achilles so difficult to heal is its relatively poor blood supply. Unlike a muscle, which heals quickly because it's richly vascularized, tendons receive very little blood flow — which means fewer of the growth factors and repair cells needed for tissue regeneration. This is exactly why standard treatments like rest, ice, and anti-inflammatory medications often fall short: they address the symptoms, but not the structural damage underneath.
For patients who've already tried physical therapy, orthotics, cortisone injections, and activity modification without lasting improvement, PRP injection for Achilles tendinopathy can be a meaningful next step.
Platelet-rich plasma therapy is a form of regenerative medicine — a field focused on stimulating the body's own repair mechanisms rather than simply masking symptoms. PRP is derived entirely from your own blood, making it a natural, biocompatible treatment with a very low risk of adverse reaction.
Here's how the process works:
Once injected, the growth factors in PRP — including PDGF, TGF-β, VEGF, and IGF-1 — signal the body to ramp up the healing process. They stimulate the production of new collagen (the structural protein that makes up tendons), recruit repair cells to the site, and promote the formation of new blood vessels. The result is true tissue regeneration, not just temporary pain relief.
At DD Podiatry's Bethesda and McLean offices, we always use ultrasound-guided PRP injections to ensure the platelets are delivered precisely to the site of degeneration — maximizing effectiveness and safety.
The clinical evidence for PRP in Achilles tendinopathy has grown substantially over the past decade. Multiple systematic reviews and randomized controlled trials have evaluated PRP against placebo, corticosteroids, and dry needling — with increasingly promising results, particularly for chronic cases.
Key findings from the literature include:
It's worth noting that PRP is not a magic bullet — results vary based on the severity and chronicity of the condition, the quality of the PRP preparation, and patient compliance with rehabilitation. That's why at DD Podiatry, we take a comprehensive approach: PRP is one powerful tool in a broader treatment plan tailored to your specific tendon pathology.
PRP injection for Achilles tendinopathy tends to work best for patients who meet certain criteria. During your consultation at our Bethesda or McLean office, Dr. Tran or Dr. Niktash will perform a thorough evaluation — including a clinical exam and diagnostic ultrasound — to determine whether you're a good candidate.
Generally, the best candidates for Achilles PRP include:
PRP may not be the right first step if your Achilles tendon pain is new and acute, or if you have a complete tendon rupture requiring surgical repair. Our doctors will always recommend the most appropriate treatment for your specific situation.
Patients often come to us having already tried several other options. Here's a straightforward comparison of the most common treatments for Achilles tendinopathy:
Physical therapy and eccentric exercises are the foundation of conservative care and should be part of any treatment plan. They address muscle imbalances and load the tendon in a controlled way to stimulate healing. However, for patients with moderate-to-severe structural tendon damage, PT alone is often insufficient for full recovery.
Cortisone (corticosteroid) injections can provide quick, short-term pain relief by reducing inflammation. However, multiple studies have shown that repeated cortisone injections can weaken the tendon, increase the risk of rupture, and do not address the underlying degenerative changes. Most guidelines recommend limiting cortisone injections around the Achilles tendon for this reason.
Shockwave therapy (ESWT) is another excellent regenerative option that uses acoustic pressure waves to stimulate healing and break up calcification. At DD Podiatry, we sometimes combine shockwave therapy with PRP for patients with more advanced tendinopathy, as the two treatments work through complementary mechanisms and can amplify results.
Surgery (debridement, tendon transfer) is reserved for cases that have failed all conservative and regenerative options. Recovery from Achilles tendon surgery typically takes 3–9 months and carries risks of complications. PRP injection for Achilles tendinopathy can help many patients avoid reaching that threshold.
PRP therapy sits in the sweet spot for patients who've gone beyond what PT and cortisone can offer, but who aren't yet surgical candidates — or who simply want to explore every regenerative option before considering surgery.
We understand that choosing a regenerative treatment is a significant decision, and we want you to feel fully informed every step of the way. Here's what a typical PRP experience looks like at our Bethesda or McLean office:
Initial consultation: Your first appointment includes a detailed history, physical exam, and diagnostic musculoskeletal ultrasound of the Achilles tendon. This lets us see exactly where the tendon damage is, assess severity, and determine whether PRP is appropriate. We'll also discuss your activity goals and previous treatments.
Pre-procedure preparation: In the days before your injection, we'll ask you to pause anti-inflammatory medications (ibuprofen, naproxen, aspirin) as these can reduce platelet activity and compromise results. We'll provide a detailed preparation checklist at your consultation.
The procedure (about 30–45 minutes): On procedure day, a small blood draw is performed. While your blood is being processed in our centrifuge, the injection site is cleaned and prepared. Using real-time ultrasound guidance, Dr. Tran or Dr. Niktash injects the concentrated PRP directly into the damaged portion of the tendon. Most patients describe the injection as a pressure sensation — we use a thin-gauge needle and can apply local anesthetic to the skin surface to minimize discomfort.
After the injection: You'll rest briefly at the office and then be able to drive yourself home. Some soreness and mild swelling at the injection site is normal for 3–7 days — this is actually a sign the healing response is activating. We'll provide a specific post-injection protocol including activity restrictions and the start of your eccentric loading program.
Recovery timeline: Most patients begin to notice meaningful improvement at 6–12 weeks, with continued improvement through 3–6 months as new collagen matures and the tendon strengthens. Depending on the severity of your condition, a second PRP treatment may be recommended at the 8–12 week mark.
There are a growing number of practices offering PRP injections in the DC metro area — but not all PRP is created equal. The quality and effectiveness of PRP therapy depends heavily on the preparation protocol, platelet concentration, and most importantly, how precisely the injection is delivered.
At DD Podiatry, we differentiate ourselves in a few key ways:
Our patients consistently tell us that what sets DD Podiatry apart is the combination of advanced technology, individualized care, and a doctor who takes the time to truly understand their situation and goals — not just their diagnosis.
Chronic Achilles tendon pain doesn't have to be something you manage indefinitely. PRP injection for Achilles tendinopathy offers a regenerative path to lasting recovery — without the risks of surgery or the downsides of repeated cortisone shots.
If you're in the Bethesda, McLean, or greater DC metro area and want to find out whether PRP is right for your Achilles tendon condition, we'd love to hear from you.
