Platelet rich plasma is an injection intervention that is being used more frequently to treat common tendons and soft tissue injuries in athlete. Usually platelet rich plasma therapy is carried out by removing a small amount of the injured athlete’s blood, then spinning it in a centrifuge so that it separates the platelets from the rest of the blood. These concentrated platelets (the Platelet rich plasma) are next injected back at the site of the athletes injury. The theory that underpins Platelet rich plasma therapy is that the growth factors that platelets usually secrete can aid tissue recovery from the injury. Platelet rich plasma is being used for a number of musculoskeletal conditions including plantar fasciitis and Achilles tendonitis. The evidence on the effectiveness of this condition is not clear with mixed results from clinical trials.
