PRP Injection

Context and indications

PRP (Platelet-Rich Plasma) is a concentrate of growth factors obtained from the patient's own blood. PRP injection is offered for chronic tendinopathies (Achilles tendon, rotator cuff, epicondylitis), early-to-moderate osteoarthritis and certain muscle or ligament injuries.

Benefits

Biological treatment using the patient's own growth factors, no risk of rejection or allergy, anti-inflammatory and regenerative effect, progressive pain reduction and functional improvement.

Procedure

A blood sample is taken (approximately 15-30 ml) and centrifuged to isolate the PRP. The concentrate is injected under ultrasound guidance directly into the joint or at the injured tendon. The entire procedure takes approximately 30-45 minutes.

Risks

Injection site pain for 2-3 days, transient local inflammatory reaction, infection (exceptional due to sterile technique). No allergy risk as it uses the patient's own blood.

Follow-up

Immediate discharge. Relative rest for 48 hours. Improvement is progressive over 4 to 6 weeks. A protocol of 1 to 3 injections spaced 3 to 6 weeks apart may be proposed.

Practical information

The procedure is performed on an outpatient basis, without anesthesia or under local anesthesia.
