TLDR The review concluded that reporting on PRP therapy is often incomplete, leading to uncertainty about its effectiveness.
This systematic review analyzed 132 Level I and II clinical studies on platelet-rich plasma (PRP) therapy across all medical specialties, with the majority conducted for musculoskeletal injuries. The review found that only 33% of the studies provided details on PRP processing or characteristics, and only 17% reported the leukocyte component. Overall, 61% of the studies found PRP to be favorable over control treatment. The authors concluded that there is a significant lack of uniformity in reporting PRP protocols and characteristics, which may contribute to the uncertainty of PRP within the medical community. They emphasized the need for more meticulous reporting of PRP protocols in human studies for proper evaluation of the therapy's efficacy.
