PRP · Your own platelets, injected back — what is established
Widely used in orthopaedics and aesthetics; evidence varies by use.
Medically reviewed by Bernard Garcia, MD
What it is
Platelet-rich plasma is prepared from a patient's own blood and injected into tissue — joints, tendons, scalp or skin. It is regulated as a minimally manipulated autologous product; no specific PRP treatment carries an FDA approval for an indication, and evidence quality ranges from reasonable (knee osteoarthritis, some tendinopathies) to weak (hair, skin).
How it works
Platelets release growth factors that may influence repair signalling. Preparations differ enormously between clinics, which makes studies hard to compare.
Research status
| Research area | Status |
|---|---|
| Knee osteoarthritis | Moderate evidence · guidelines mixed |
| Tendinopathy | Mixed evidence |
| Hair loss | Small studies |
| Skin / aesthetic | Weak evidence |
Status reflects published research context only and is not a statement of safety, efficacy, or suitability for any person.
