Platelet Rich Plasma Injections (PRP)
Blood contains red cells, white cells and platelets. Platelets contain hundreds of proteins called growth factors which are important in the healing of injuries. Platelets also have an important role in the clotting of blood. Platelet Rich Plasma (PRP) is where you have a high concentration of platelets and therefore growth factors, being up to 5 to 10 times greater than in normal blood. PRP is then injected by a Radiologist into the requested body region under ultrasound guidance.
What is a Platelet Rich Plasma (PRP) Injection?
Blood contains red cells, white cells and platelets.
Platelets contain hundreds of proteins called growth factors which are important in the healing of injuries. Platelets also have an important role in the clotting of blood.
Platelet Rich Plasma (PRP) is where you have a high concentration of platelets and therefore growth factors, being up to 5 to 10 times greater than in normal blood. To achieve this, a small amount of blood is taken from the patient and placed in a test tube, which is spun in a centrifuge, so that concentrated platelets (PRP) is separated from other blood cells. The PRP is then injected by a Radiologist into the requested body region under ultrasound guidance.
How does PRP work?
Platelets play an important role in accelerating the healing process and modulating an inflammatory response. An injection of platelet rich plasma (PRP) which contains concentrated growth factors, directly into the affected tissue or joint, may accelerate the healing process and improve function and reduce pain.
Why would I have been referred for this procedure?
Your referrer has likely sent you for a PRP injection because you have a chronic tendon injury called “refractory tendinosis” affecting areas such as the elbow in tennis or golfer’s elbow or Achilles or patellar tendons or because you have mild to moderate osteoarthrosis causing pain.
How do I prepare for a PRP Injection?
There is no specific preparation prior to the procedure.
If you have had an X-Ray, ultrasound, CT or MRI scan, please bring these to your appointment.
What happens during a PRP Injection?
The Radiologist will initially discuss the procedure with you.
A small amount of blood is drawn from the patient into a test tube which is then placed in a centrifuge and spun for a few minutes so that the concentrated platelets or platelet rich plasma “PRP” is separated from other blood cells.
Using a sterile technique and under ultrasound guidance, the Radiologist will inject a small amount of local anaesthetic into the overlying soft tissues to numb the area, then inject the PRP into the requested body region while visualising this using the ultrasound machine.
How long does a PRP Injection take?
A PRP injection normally takes approximately 30 to 40 minutes depending on the body region involved.
How much will the PRP injection cost?
Our booking coordinators will advise you of all costs involved with your PRP Injection prior to your appointment.
Will the PRP injection work?
Results can be variable and can take several weeks before the patient feels a beneficial effect.
How many PRP Injections will I need?
For chronic tendinosis, the patient often requires two PRP injections, 1 month apart.
For mild to moderate osteoarthrosis, the patient often requires three PRP injections into the joint, 1 month apart.
Are there any after effects of a PRP Injection?
The risks following a PRP injection are minimal.
PRP injections are designed to use platelets to trick your body into thinking that the affected area is injured, therefore triggering a healing response from your body.
As a result, you may experience increased pain at the injection site for the first one to two weeks.
Simple regular pain relief, rest, ice and elevation of the limb for 48 hours may be of benefit.
Please avoid anti-inflammatory medications for six weeks after the PRP injection (e.g. ibuprofen, naproxen).
Most patients see the most benefit approximately 4–6 weeks after the injection.
The incidence of other problems such as infection, tissue damage or nerve injuries are no higher that if you had a corticosteroid injection.
