PRP (platelet-rich plasma) is a concentrate of your own platelets, prepared from a small blood sample and injected under ultrasound into a damaged tendon, ligament or joint. Platelets release growth factors that support repair. It is a day-care procedure of about forty-five minutes, with results building over four to twelve weeks.
Because PRP is your own blood, allergic reaction does not occur. Infection is rare with sterile technique. A temporary pain flare is common and expected. Outcomes vary: the strongest evidence is for tennis elbow, mild to moderate knee arthritis and tendinopathies; results are slower and less predictable in advanced arthritis. PRP is not a cure for arthritis and does not regrow cartilage; it aims to reduce pain and improve function.
The injection is done under local anaesthesia. Soreness for a few days afterwards is normal.
They interfere with the platelet response the injection depends on.
Twelve months or more for many tendon problems; six to twelve months in knee arthritis, after which it can be repeated.
No. PRP uses the growth factors in your own platelets; stem-cell–based options such as BMAC and SVF are separate regenerative treatments, chosen to suit the problem.
Usually not. Ask the clinic about the exact fee before booking.
