What is Autologous Conditioned Plasma (ACP)?

Autologous Conditioned Plasma (ACP) is a method of concentrating platelets and growth factors from your own blood to re-inject into the site of injury to promote healing. A small amount of venous blood is drawn from your arm using a specially designed needle and syringe. The syringe is then placed into a centrifuge and spun. This separates the plasma, which contains platelets and other growth factors from the blood.

The plasma is then extracted carefully and re-injected to the target area.

What should I do after the treatment?

1) Rest the affected area for the first 24-48 hours from moderate to vigorous exercise. Daily activities are ok. Ideally, you should avoid intensive activities for the first 2 weeks after injection.

2) If there is pain during this period, ice the area and/or take pain medications.

3) Any bandage placed over the injected site can be removed after 1-2 hours, if there is no bleeding.

When is ACP considered for treatment?

The ACP injection procedure is not regarded as a first line treatment for injuries. Therefore, it is usually considered when conventional and evidence-based treatments have been tried and have not resulted in the desired outcomes. There is no guarantee that the ACP injection will improve your symptoms.

Possible Risks or Side Effects

ACP injection is a safe procedure. There may be pain, bleeding, or bruising at the blood draw or injection site. There is also a small risk of infection at the injection site, which typically presents with increased pain and redness 2-4 days after the injection. You may have a fever, find that movement is painful and the injection site may feel warm. Please see your family doctor immediately, or go to our Accident and Emergency Department, if you suspect that you have developed an infection after an injection.
