PRP vs Steroid Injection
Steroid injections reduce inflammation quickly but do not repair tissue. PRP uses your own concentrated platelets to stimulate biological healing, with a slower but longer-lasting effect. The right choice depends on the diagnosis, tissue quality and your goals.
At a glance
| Criterion | PRP | Steroid injection |
|---|---|---|
| Primary mechanism | Growth-factor mediated tissue healing | Anti-inflammatory suppression |
| Onset of relief | 4–8 weeks | 24–72 hours |
| Typical duration | 6–18 months, often durable | 6–12 weeks; variable |
| Best evidence | Tennis elbow, patellar and Achilles tendinopathy, early knee OA | Frozen shoulder, bursitis, acute synovitis |
| Tissue effect | Regenerative, no atrophy | Can weaken tendons if repeated |
| Return to sport | 2–6 weeks graduated | Often immediate |
| Cost (Oxford, private) | Higher | Lower |
When PRP is preferred
- Chronic tendinopathy that has failed physiotherapy
- Mild-to-moderate osteoarthritis where you want to delay surgery
- Repeated steroid injections would risk tendon damage
When Steroid injection is preferred
- Acute inflammatory flare needing rapid relief
- Frozen shoulder, subacromial bursitis, trigger finger
- Short-term symptom control before an event or procedure
Bottom line
PRP is regenerative and best for chronic tendon or early joint problems. Steroid is anti-inflammatory and best for short-term relief in inflammatory conditions. Ultrasound guidance is essential for both.
Frequently asked questions
Can I have both?
Yes — sequenced correctly. A steroid injection can settle an acute flare, and PRP can follow once inflammation has calmed to stimulate healing.
Is PRP better than steroid for tennis elbow?
Randomised trials show PRP produces superior 6- and 12-month outcomes in chronic lateral epicondylopathy, while steroid gives faster short-term relief.
