Platelet rich plasma (PRP) treatment involves taking your blood, concentrating the platelets using a centrifuge, and then re-injecting the concentrated platelets from the blood into areas of chronic pain using ultrasound guidance. Platelets contain growth and healing factors and are an important part of the healing process. The most evidence is for mild to moderate knee osteoarthritis however it is not completely proven. There is mixed evidence for osteoarthritis in other areas and for tendinopathies.

Due to the mixed evidence it is not covered by the major health insurance providers such as ACC and Southern Cross. An assessment is required before this can be offered.
