Both cortisone and PRP are injections, but they are fundamentally different tools. Cortisone is an anti-inflammatory medication that acts quickly and temporarily; PRP is a regenerative approach using your own platelets to support healing over a longer period.
How cortisone injections work
Cortisone is a corticosteroid that suppresses inflammation in the injected area. It can provide relatively fast relief, which makes it useful for acute flare-ups, but the effect is temporary, and repeated use is limited because cortisone can weaken tissue over time.
How PRP injections differ
PRP delivers a concentrated sample of your own platelets to the area. Rather than suppressing a response, it is intended to support the tissue's own healing pathways. Benefits, when they occur, tend to build slowly, and multiple sessions are often needed.
| Factor | Cortisone | PRP |
|---|---|---|
| Source | Synthetic corticosteroid | Your own blood, processed |
| Onset | Days | Weeks to months |
| Duration of effect | Temporary | Includes healing response |
| Repeat use | Limited over time | Performed in planned courses |
| Typical purpose | Quiet acute inflammation | Support tissue response |
Which is right for you
There is no universal winner. Some patients benefit from a cortisone injection to break a cycle of pain before building strength; others are better served by a slower regenerative approach. The decision depends on the diagnosis, the tissue, your history, and your goals.
What the evidence shows for tennis elbow
Lateral epicondylitis, commonly called tennis elbow, is one of the best-studied comparisons. Recent meta-analyses show a time-dependent pattern: corticosteroids provide faster relief in the first month or two, while PRP shows stronger pain and function results from about three to six months onward. A 2023 systematic review and meta-analysis in the Journal of Shoulder and Elbow Surgery found corticosteroids superior at 1 month but PRP superior for pain at 3 and 6 months, and a 2025 meta-analysis of 26 randomized trials found PRP favored beyond 6 months. Neither injection is uniformly better, which is why the diagnosis and your timeline matter.
