PRP has its best evidence in tennis elbow, where trials found better 1-year results than cortisone (Peerbooms, 2010; Mishra, 2014). Results for plantar fasciitis are promising; for chronic Achilles tendinopathy, a JAMA trial (de Vos, 2010) found no benefit over saline. Preparation differs between clinics.
| Tendon | PRP evidence |
|---|---|
| Tennis elbow | Positive trials |
| Plantar fasciitis | Some positive trials vs cortisone |
| Patellar tendon | Small studies |
| Achilles | Main trial negative |
| Rotator cuff | Mixed |
