Platelet-rich plasma (PRP) injections have become one of the most widely discussed treatments in regenerative medicine, and many patients with Achilles tendon problems wonder whether PRP could help them avoid surgery and get back on their feet. PRP is frequently promoted as a cutting-edge option that can relieve pain and improve function, but does the latest high-quality evidence actually support its use for Achilles tendinopathy? In this article, I review a comprehensive meta-analysis of randomized clinical trials to help you understand what the research really shows — and discuss an alternative treatment approach that may offer better results.

What Is Achilles Tendinopathy?
Achilles tendinopathy, often referred to as Achilles tendonitis, is a common condition that causes pain, stiffness, and swelling in and around the Achilles tendon — the thick band of tissue connecting the calf muscles to the heel bone. It typically develops from overuse or repetitive stress, particularly in runners, athletes, and individuals who increase their physical activity too quickly. This condition can make walking, running, and even standing painful, significantly affecting daily activities and overall quality of life.
How Is Achilles Tendinopathy Typically Treated?
Treating Achilles tendinopathy can be challenging because the condition often becomes chronic and resistant to simple interventions. Traditional treatments usually begin with rest, ice, and anti-inflammatory medications such as NSAIDs. Physical therapy with structured tendon-loading exercises remains the gold standard for promoting healing and improving function. In some cases, corticosteroid injections are used to reduce inflammation, but these carry notable risks, including weakening the tendon and increasing the chance of rupture. Because of these limitations, many patients and clinicians seek newer treatment options that might accelerate recovery and improve long-term outcomes.
What Is Platelet-Rich Plasma (PRP)?
Platelet-rich plasma, or PRP, is one of the newer treatments gaining attention for tendon injuries, including Achilles tendinopathy. PRP is prepared by drawing a small amount of the patient's own blood and spinning it in a centrifuge to concentrate the platelets — cells that play a central role in healing. This concentrated preparation also contains growth factors and proteins believed to stimulate tissue repair, reduce inflammation, and promote regeneration. The concept behind PRP is compelling: using the body's own healing components to jumpstart recovery without drugs or surgery.
Does PRP Work for Other Tendon Conditions?
PRP has been studied extensively and has demonstrated meaningful benefits in several other tendon conditions, including elbow tendinopathy — commonly known as tennis elbow and golfer's elbow — as well as rotator cuff tendinopathy and tears. Because of these results, PRP has become increasingly popular among athletes and clinicians seeking regenerative medicine options. However, despite this promise in other areas, the scientific evidence supporting PRP's effectiveness specifically for Achilles tendon problems has remained unclear, making it essential to carefully examine the latest research before embracing it as a standard treatment.
What Does the Latest Research Say About PRP for Achilles Tendinopathy?
A recent comprehensive meta-analysis published in Clinical Orthopaedics and Related Research (Barreto et al., 2024) examined six randomized clinical trials with a total of 422 patients. The study compared PRP injections against placebo treatments such as saline or sham injections, as well as other active interventions including high-volume injections and stromal vascular fraction (SVF) therapy. The main outcomes assessed were pain relief measured by the VAS pain scale and functional improvement assessed using the VISA-A score, evaluated at three months, six months, and one year after treatment.
Key Findings: PRP Did Not Outperform Placebo
The meta-analysis found that PRP did not provide any significant improvement in either pain or function for patients with Achilles tendinopathy compared to placebo. Specifically, there was no meaningful difference in VISA-A functional scores at three months, six months, or even one year after treatment. Similarly, pain levels measured by the VAS showed no significant reduction at three months post-injection. When compared to other treatments such as high-volume injections, PRP showed similar outcomes and offered no clear advantage. These results challenge the widespread belief that PRP is an effective treatment for Achilles tendonitis.
Should You Get PRP Injections for Achilles Tendinopathy?
Given the lack of demonstrated benefit in improving pain or function, combined with the high costs associated with PRP treatment, the current evidence does not support recommending PRP for Achilles tendinopathy in clinical practice. While PRP has gained popularity as a regenerative medicine option, patients and clinicians should exercise caution about its use for this condition until more definitive evidence emerges.
In my clinical practice, I have seen mixed results with PRP for Achilles tendinopathy. Some patients respond well, while others continue to experience persistent symptoms. This is consistent with what the research demonstrates — and it is one of the reasons I have increasingly turned to an alternative approach for patients with chronic, stubborn Achilles tendon problems.
Ultrasound-Guided Percutaneous Needle Tenotomy: A Promising Alternative
There is a newer treatment that is changing how clinicians approach chronic Achilles tendon problems. Ultrasound-guided percutaneous needle tenotomy involves using ultrasound guidance to direct a small needle that repeatedly fenestrates (punctures) the damaged tendon tissue. This process creates small, controlled injuries that trigger the body's natural healing response by increasing blood flow and inflammation to an area where the tendon has become stuck in a chronic, non-healing state.
A systematic review published in Sports Health (Maag et al., 2024) found that percutaneous needle tenotomy (PNT) and related ultrasound-guided needle techniques are safe and effective for reducing pain and improving function, especially for tendons that have not responded to more conservative approaches. The review examined 10 studies across 11 tendon sites and reported overall improvements in pain, function, and quality of life with minimal adverse effects. For Achilles tendinopathy in particular, patients reported significant pain relief and improved movement, with many expressing high satisfaction even in the long term.
There is also early evidence suggesting that combining percutaneous needle tenotomy with PRP injections may enhance outcomes, although more research is needed to confirm this. Overall, ultrasound-guided needle tenotomy offers an exciting option for patients struggling with chronic Achilles tendinopathy that has not responded to conventional treatments.
The Importance of Rehabilitation After Tenotomy
The results of ultrasound-guided needle tenotomy tend to be even more effective when combined with physical therapy or a structured home-based rehabilitation program for the Achilles tendon. In my practice, I often recommend a progressive tendon-loading protocol following the procedure to maximize recovery and help patients return to their activities with confidence. A comprehensive approach that pairs the procedure with targeted rehabilitation gives patients the best chance for long-term improvement and return to full function.
