Platelet Rich Plasma (PRP) injections

                                          PRP Injections– PATIENT INFORMATION

What are PRP injections?

PRP injections work in a similar way to cortisone injections. The difference is, PRP is made from your own blood. The blood is spun, and the red and white blood cells are removed. Smaller blood cells (called platelets) are concentrated within the remaining fluid (called plasma), and this is then injected into the injured site. (It is the platelet element of blood that assists with the healing process) 

What are the benefits and risks of PRP injections?


PRP is a product of your own blood. It assists with the healing of your injury rather than just eliminating the symptoms - Evidence proves that PRP injections are significantly more effective and longer lasting than cortisone injections - PRP injections treat many musculo-skeletal problems including mild to moderate osteoarthritis.


As with any procedure, there is always the risk of:   Allergic reaction - in this case to the local anaesthetic administered prior to PRP injection, Infection, and bruising - However, these complications are extremely rare.


At the time of booking you will be asked if you have had a corticosteroid injection in the 4 weeks prior to your preferred appointment date.  If applicable, you will also be asked to stop taking any non-steroidal anti-inflammatory medications 7 days before and after, as these interfere with platelet function. You will be advised to get a blood test a few days before your appointment date to ensure you have a sufficient platelet count. This helps maximise volume, which helps maximise results.

Day of appointment

Your appointment will last approx. 1 hr.  Depending on the site and severity of the injury,  20ml - 60ml of your blood will be collected (in the same way as a blood test) then spun in a centrifuge to separate the blood cells and platelets. Following a local anaesthetic, the radiologist will administer the PRP injection under imaging guidance.

After the procedure

You will be advised to refrain from any significant activity for the body part injected for 1 week. Daily living activities are permissible, but no deliberate exercise such as running, weight training or other sporting pursuits. You will be given a pain chart to monitor and record your pain levels over the following 2 week period. After this time, your referring doctor may wish to consult with you to discuss your progress. You will also need to book your second appointment for 6 weeks after your original visit.
