History

Historical Context

PRP, first named by Kingsley in 1954 and expanded through 1960s blood-bank research, became common in sports medicine by the 1970s and was used in Italy’s cardiac surgery in 1987. After WADA lifted its ban in 2011, fighters like Conor McGregor cite the therapy—platelet concentrations 3–5 times normal—to accelerate ACL recovery and reshape UFC scheduling.
