PRP injections can be applied to various musculoskeletal problems to promote healing and decrease pain and inflammation of injured tendons, ligaments, muscles and joints. PRP injections are prepared from a simple blood draw. The blood is placed in a sterile centrifuge. The sterile centrifuge extracts the activated platelets. The activated platelets are then injected into the abnormal tissue, releasing growth factors that recruit and increase the proliferation of reparative cells. PRP injections have been shown to improve function and decrease pain and inflammation with relatively little to no side effects as this procedure utilizes a patient's own blood.
