Platelet plasma rich products in musculoskeletal medicine: any evidence?

Platelet reach plasma (PRP) is considered to accelerate muscle and tendon healing and allow early return to elite competition, and it is often recommend as best practice for management of musculoskeletal injuries. Even though several growth factors abundant in PRPs have been extensively studied in tissue regeneration, the key factors are yet unknown. Given our rudimentary knowledge of the mechanism of action of the PRPs, it is challenging to use this technology to promote early healing, and produce improved and accelerated functional recovery. We prompt researchers to undertake appropriately powered level I studies with adequate and relevant outcome measures and clinically appropriate follow up.
