Platelet-rich plasma is also known as platelet-enriched plasma, platelet-rich concentrate, and autogenous platelet gel.
It is an autologous suspension of platelets prepared from whole blood using double centrifugation techniques.
Before using, platelets are activated with calcium chloride and the resultant platelet clot may be applied to the site of injury.
Platelets begin secreting these proteins within ten minutes of clotting.
Platelet-rich plasma is highly effective for treating rotator cuffs, epicondylitis, shoulder osteoarthritis, subacromial impingement, knee osteoarthritis, patellar tendinosis, plantar fasciitis, and tendo-achilles tears.
