Platelet rich plasma is an extraction of fluid of a persons blood which is concentrated in platelets. Platelets are special cell fragments in our blood that help initiate the initial stages of healing. They have several biochemical agents which initiate the healing response for various tissues.

Where is it used ?

PRP has been used for various tendonopathies( tendon disorders) throughout the body such as tennis elbow. It is helpful in tendonopathies because tendons inherently have a poor blood supply and therefore have a limited repair response. The platelets are thought to release growth factors to help initiate a healing response in the area that the tendon is damaged. Other tendons which prp has been used include the patellar tendon, quadriceps tendon , Achilles’ tendon and the plantar fascia. There is also some data to suggest it helps patients with chondral lesions and osteoarthritis.
