Uso del plasma rico en plaquetas en cirugía ligamentosa de rodilla / Use of platelet rich plasma in knee ligament surgery

ABSTRACT

Platelet Rich Plasma (PRP) is used in musculoskeletal lesion surgery, including muscle, bone, tendons and ligaments. PRP might accelerate the healing process and the integration of the graft, allowing an earlier return to sports activities of patients. PRP is obtained from autologous blood, which is centrifuged, obtaining platelet and supposedly growth factor concentrations three to five times higher than those of regular blood. The clinical results of studies performed in Chile and elsewhere on PRP use in knee anterior cruciate ligament (ACL) reconstruction have been variable. Therefore, there is not enough evidence to support or deny the usefulness of PRP in ACL reconstructions.
