Platelet-Rich Plasma Injection / 대한정형외과학회잡지

ABSTRACT

Platelet-rich plasma (PRP) supplies numerous growth factors from concentrated platelets required to promote the healing process of injured or degenerated tissue. PRP is already a popular option to treat a variety of musculoskeletal injuries and diseases, even though the precise mechanism of action is not completely understood. Varying outcomes, from favorable to poor, after PRP injection may arise from interstudy differences with respect to 4Ds (Drug [PRP], Delivery [application method], Donor [patients], and Disease [stage of rotator cuff disease]). In addition, there is no standard treatment regimen (injection location, number, interval, volume). Therefore, precise outcome measures as well as long-term follow-up are required to accurately evaluate the efficacy.
