Abstract

Hamstring muscle strains are among the most common injuries in sport, but despite increasing research into the epidemiology, aetiology and management the rates of both injury and re-injury remain high. Typically, hamstring injury management is conservative, but recently the use of autologous platelet enriched plasma (PEP), has been proposed as a treatment tool which may optimise muscle regeneration and enhance clinical outcomes. Unfortunately however, there remains little scientific evidence for the clinical use of these techniques in muscle injuries. This report outlines the current clinical evidence for the use of PEP in muscle injuries. A case report of a patient with a grade II semi-membranosus muscle strain, injected with PEP while concurrently using platelet inhibitors will illustrate the clinical, radiological and theoretical challenges of this new technique. Further clinical research into the clinical utility of PEP in muscle injury is required and it is incumbent on Sports Physicians and researchers to address this research deficit, if PEP is to live up to its high public profile.
