Abstract: Platelet-rich plasma（PRP） is a new autologous biological preparation with high concentrations of platelets and growth factors.In recent years，a large number of clinical studies have proved that PRP can effectively accelerate the repair of tissues，so it is used for treating tendon，ligament，cartilage and muscle injuries little by little，which also has attracted much attention in the field of foot and ankle surgery.In this article，we systematically reviewed the recent studies about PRP's preparation process and clinical use for foot and ankle injuries，and explored its application prospect.
