PRP (Platelet Rich Plasma) and Osteoarthritis

E-mail Print

Recently, emerging evidence has suggested that Platelet Rich Plasma (PRP) may also be of assistance in the treatment of osteoarthritis and other degenerative conditions of joints. It is felt that the growth factors may assist in cartilage regeneration and also mediate benefit by providing an immune modulating effect, whereby the inflammatory cascade is dampened. Thus, PRP may act as a natural anti-inflammatory substance to result in symptomatic pain relief of sore arthritic joints.

The process of obtaining PRP for use in treatment of osteoarthritis of joints is identical to that outlined for PRP injections of tendons.

Patients and referring clinicians may have recently become aware of this procedure in the media:
