Platelet-rich plasma (PRP) injections

What is PRP?

PRP is made from a small sample of your own blood. A blood sample is taken, similar to a routine blood test, and processed using a centrifuge to separate its components. The concentrated platelet-rich plasma is then injected directly into the affected knee.

PRP’s potential benefits are thought to result from inflammation modulation and tissue signalling pathways, although long-term structural changes such as cartilage repair are not clearly demonstrated.

PRP is most commonly used in mild to moderate knee osteoarthritis when longer-lasting symptom relief is sought without using steroids.

Benefits

• Uses your body’s own healing cells
• May reduce pain and stiffness

• No risk of allergic reaction
• Performed in an outpatient setting

Limitations

PRP may be helpful for patients seeking a more natural treatment approach.
