PRP Injections
Platelet-rich plasma therapy, sometimes called PRP therapy or autologous conditioned plasma (ACP) therapy, attempts to take advantage of the blood's natural healing properties to repair damaged cartilage.
​
There is growing evidence that PRP injections can be beneficial to patients with mild to moderate knee arthritis.
No anaesthetic is required for PRP Injections.
​
A course of treatment consists of 3 injections given over the period of 3-4 weeks.
The first part of the procedure consists of a blood sample being taken from the patient. The blood sample is then prepared in a centrifuge.The platelets in the plasma layer are separated from other blood components. Finally the resultant PRP is injected into the knee.
PRP therapy to treat knee osteoarthritis appear to:
-
Inhibit inflammation and slow down the progression of osteoarthritis
-
Stimulate the formation of new cartilage
-
Increase the production of natural lubricating fluid in the joint, thereby easing painful joint friction
-
Contain proteins that alter a patient's pain receptors and reduce pain sensation
There is mixed evidence on the use of PRP, but on balance the majority of evidence suggests that it can be beneficial for patients with mild to moderate knee arthritis.
