Acute soft-tissue lesions and chronic overuse injuries in the sports medicine field are very frequent and in most cases, difficult to treat. Tissue repair in musculoskeletal lesions is often too slow and sometimes incomplete for a given athlete. The fastest, most complete recovery is of primary importance, and keeping the delay until return-to- field as brief as possible, a priority. Many bioactive proteins and growth factors amongst others influence healing processes. Administration of Platelet Rich Plasma enables the production, from the patient’s own blood, of natural, high concentrations of autologous growth factors. Basic research and animal studies are promising, but evidence- based studies examining the treatment of human musculoskeletal lesions by Platelet Rich Plasma are still lacking. Nevertheless, such treatment is increasingly used in sports medicine clinical practice and much is expected of growth factor injections. The aim of this non exhaustive review is to analyze the existing literature published in the fields of sports medicine. The results of this analysis do not permit us to recommend the systematic and generalized use of Platelet Rich Plasma injections in the management of sport injuries. Nevertheless, a few promising results have to be mentioned, but high-quality studies are needed to provide scientific evidence about these injections’ effectiveness.
