    PRP vs Cortisone: Which Is Right for You?

    Comparing two popular injection therapies for joint pain and inflammation.

    February 11, 2026
    PRP and corticosteroid injections represent fundamentally different approaches to musculoskeletal pain. Cortisone suppresses inflammation quickly, but temporarily. PRP harvests growth factors from your own blood to stimulate lasting tissue repair. For patients weighing these two options, understanding the mechanisms and the evidence is essential.

    How Corticosteroid Injections Work

    Corticosteroids are synthetic versions of cortisol, a hormone the adrenal glands produce. When injected near an inflamed tendon, joint, or bursa, they block prostaglandin synthesis and suppress immune cell activity, reducing swelling, warmth, and pain within days.
    The relief is real and often dramatic, which is why cortisone injections remain widely used. However, the anti-inflammatory effect is temporary. Once the steroid clears (typically 4–12 weeks), the underlying pathology, damaged collagen, degenerative cartilage, chronic tendinopathy, remains untreated.

    How PRP Works Differently

    Platelet-rich plasma concentrates your own platelets, typically 5–10 times above baseline, and injects them at the injury site. Platelets release growth factors including PDGF, TGF-beta, VEGF, and IGF-1, which recruit stem cells, stimulate collagen synthesis, and promote vascularization.
    Rather than dampening inflammation, PRP redirects it toward a controlled healing response. This distinction matters: chronic tendinopathy involves failed healing, not ongoing acute inflammation. PRP addresses the biological reason tissue is not repairing itself.

    What Head-to-Head Research Shows

    Several randomized controlled trials have directly compared PRP and corticosteroid injections. A landmark 2011 study by Gosens et al. (PMID 21422467) followed 100 patients with chronic lateral epicondylitis for two years. At 26 weeks, PRP-treated patients showed 64% improvement in pain scores versus 24% for the cortisone group, a difference that widened at the two-year mark.
    A 2020 randomized trial (PMID 32699149) comparing PRP with corticosteroid for rotator cuff tendinopathy found PRP superior at 6 and 12 months on both pain and functional outcomes. The cortisone group showed faster early relief but significantly worse outcomes at follow-up, a pattern seen across multiple musculoskeletal conditions.

    The Risks of Repeated Corticosteroid Use

    Corticosteroids are generally safe for occasional use, but repeated injections carry documented risks. Studies show that multiple cortisone injections into tendons can weaken collagen architecture, increasing rupture risk. In joints, repeated steroid exposure has been linked to accelerated cartilage loss, the opposite of the treatment goal.
    Systemic effects including blood sugar elevation, transient adrenal suppression, and skin depigmentation at the injection site are more common with frequent use. Guidelines from most orthopedic societies recommend limiting cortisone injections to 3–4 per year at any single site, and many clinicians suggest far fewer.

    When to Choose PRP Over Cortisone

    PRP is generally preferred when the condition is chronic (symptoms lasting more than 3–6 months), when previous cortisone injections provided only temporary relief, when imaging shows degenerative changes rather than acute inflammation, or when you are concerned about the long-term risks of repeated steroid use.
    Cortisone may still be appropriate for acute flares that prevent participation in rehabilitation, or when rapid short-term relief is the priority. Many orthopedic physicians now view PRP as the better choice for definitive, longer-lasting treatment of chronic tendinopathy and joint degeneration.
