The preparation of therapeutic doses of growth factors consists of an autologous blood collection from the patient. The plasma is then separated (via a special centrifuge), and then application of the plasma rich in growth factors is injected into the damaged area. In other words, PRP is done just like any other prolotherapy treatment, except the solution used for injection is plasma enriched with growth factors from your own blood. Typically 2-3 treatments are necessary per area given every 4 weeks like other prolotherapy sessions.
In scientific literature, reports of soft tissue injuries treated with PRP include: tendonopathies, tenonosis, acute and chronic muscle strains, muscle fibrosis, ligamentous sprains and joint capsular laxity, specifically in the extremities. PRP has also been utilized to treat intra-articular injuries such as arthritis, arthrofibrosis, articular cartilage defects, meniscal injury, and chronic synovitis or joint inflammation.
PRP has been used successfully to enhance surgical outcomes in maxillofacial, cosmetic, spine, orthopedic, and podiatric surgery. In regard to its use today, you will see that the majority of doctors using it apply it onto their current knowledge -base of prolotherapy. In other words, the doctors doing PRP are using it as a proliferant, much like they use other solutions in prolotherapy. In simple terms, PRP is a type of prolotherapy!
