PRP Therapy vs. Cortisone Injections: Which Is Right for You?

Both can reduce joint pain. They get there through completely different mechanisms - and which one makes sense depends on a lot more than which sounds newer.

By Bhadresh L. Bhakta, M.D. Board-Certified Pain Management

Patients often come in having already read about both options and feeling more confused, not less. One article says cortisone is outdated. Another says PRP is overhyped. The truth is that both have real clinical applications - and neither is universally superior.

Here's a clear-eyed look at how each works, who tends to benefit from each, and the questions worth asking before you choose.

How Cortisone Injections Work

Cortisone - more precisely, corticosteroid medication - is a powerful anti-inflammatory. When injected into or near an inflamed joint, bursa, or tendon, it reduces the immune response driving swelling and pain. The effect is relatively fast: most patients notice meaningful improvement within two to five days.

The relief can last anywhere from a few weeks to several months, depending on the condition, the joint involved, and how inflamed the tissue was at the time of injection. For acute flares of arthritis, bursitis, or tendon irritation, cortisone often provides the fastest path back to function.

The main limitation is frequency. Frequent cortisone injections in the same location - especially more than three or four times per year - have been associated with cartilage thinning and weakening of nearby tendons over time. So while cortisone is effective for managing flares and getting relief when you need it, it's generally not something to lean on indefinitely.

How PRP Therapy Works

Platelet-rich plasma (PRP) therapy works differently at a fundamental level. Instead of suppressing the inflammatory response, it uses a concentrated preparation of your own platelets to potentially stimulate the body's natural healing functions.

Here's the basic process: a small amount of your blood is drawn and spun in a centrifuge to concentrate the platelets. The concentrated PRP is then injected into the target tissue. Platelets contain growth factors that play a role in tissue repair and regeneration. The idea is to deliver those factors directly where the healing needs to happen.

PRP takes longer to work than cortisone - the improvement is typically gradual over several weeks rather than days. But for certain conditions, particularly tendon injuries and early-to-moderate osteoarthritis, the results may last longer and address the underlying tissue rather than quieting the inflammation temporarily.

Where They Diverge: The Practical Differences

The clearest way to think about the difference: cortisone tends to be faster and is often the right choice when you need relief quickly, when the problem is primarily inflammatory, or when a short-term window of relief will let you rehabilitate the area. PRP tends to be slower but potentially more durable, and it may be a better fit when you've had cortisone multiple times without sustained benefit, when the underlying tissue has actual structural damage, or when you want to minimize steroid exposure.

Conditions where cortisone is often a strong first choice:

  • Acute bursitis flares in the hip, shoulder, or knee
  • Inflammatory arthritis with active joint swelling
  • Trigger points and localized muscle inflammation
  • Spinal nerve irritation (in combination with epidural delivery)

Conditions where PRP is more commonly considered:

  • Chronic tendon problems - particularly rotator cuff tendinopathy, Achilles tendinopathy, and tennis elbow - that haven't responded well to other treatments
  • Early-to-moderate knee osteoarthritis, especially when cortisone has provided diminishing returns
  • Ligament injuries with partial tearing
  • Hip pain related to labral or soft tissue damage

The Insurance Question

This matters practically. Cortisone injections are generally covered by insurance when medically indicated. PRP is not covered by most major plans - it's still considered investigational by many insurers for most applications. That doesn't mean it's unproven; it means the insurance coverage has lagged behind clinical adoption. But cost is a real consideration, and it's worth discussing at your consultation.

Why the Comparison Gets Complicated

The research on PRP has grown substantially. Some studies in knee osteoarthritis and certain tendinopathies suggest PRP can produce improvements comparable to cortisone at the six-to-twelve-month mark, while other trials have found less advantage. The evidence varies by condition, by PRP preparation method, and by patient population, which is part of why a blanket recommendation isn't possible.

Dr. Bhakta's approach is to evaluate each patient's specific anatomy, diagnosis, treatment history, and goals before recommending one over the other. The patient who's had three cortisone injections in a shoulder tendon without lasting benefit is a different clinical picture than someone with a first-time bursitis flare. A recommendation that's right for one may not be right for the other.

Questions Worth Asking at Your Consultation

You don't need to arrive with a decision already made. You do benefit from arriving with good questions. These are the ones that tend to move the conversation forward:

  • What's actually driving my pain - inflammation, structural damage, or both? The answer shapes everything that follows, because the two treatments target different problems.
  • If I've had cortisone in this joint before, how long did each round last? A pattern of shorter relief with each injection is useful information, not a failure.
  • What would the full cost of PRP look like for me? Since most plans don't cover it, ask about the total and how payment works before you commit.
  • How many sessions would you anticipate, and how will we know it's working? Agreeing on what improvement looks like makes it easier to judge results honestly.
  • Are there other options for this joint worth considering? Depending on the diagnosis, approaches such as viscosupplementation may also be part of the discussion.
  • What's the plan if this doesn't give me the relief I'm hoping for? Knowing the next step in advance takes some of the pressure off the decision.

When to See a Pain Specialist

If you've been managing joint pain with rest, anti-inflammatory medications, and activity modification for more than four to six weeks without improvement, that's a reasonable point to get a specialist's evaluation. You don't need to exhaust every option first.

A thorough assessment - including imaging review if relevant - gives you a clearer picture of what's actually happening in the joint and which treatment approach gives you the best chance of meaningful, lasting relief.

Frequently Asked Questions

Is PRP more effective than cortisone for joint pain?

It depends on the condition and what you're trying to accomplish. Cortisone often provides faster relief, while PRP may offer longer-lasting results for certain soft tissue conditions. A specialist evaluation helps determine which approach makes more sense for your specific diagnosis.

How many PRP injections are typically needed?

Most treatment protocols involve one to three injections, depending on the condition and how well you respond. Your physician will monitor your response and adjust accordingly.

Does cortisone damage joints over time?

Repeated cortisone injections at high frequency have been associated with cartilage thinning and changes to surrounding tissue over time. Most physicians limit injections in a given joint to three or four per year for this reason. Occasional cortisone injections, used appropriately, are generally considered safe.

Is PRP covered by insurance?

PRP therapy is not currently covered by most major insurance plans, as it is still considered investigational for many indications. Cortisone injections are generally covered when medically indicated. Your physician's office can discuss costs and options at your consultation.
