Ankle injection prp is a treatment by injecting high concentration platelet plasma into the ankle joint cavity. PRP in Chinese is high concentration platelet plasma or platelet rich plasma, which is plasma containing high concentration of platelets made by using one’s own blood, and it has the effect of promoting autologous cell regeneration and repairing aging damage, and there is no rejection reaction after use. PRP is suitable for the treatment of large joint injuries such as ankle joints and knee joints. Platelet-rich plasma is injected into damaged joints to repair cartilage damage in the joints, etc., and the treatment effect is relatively good. Injection of PRP into the ankle joint is an invasive operation, which is prone to cause local soft tissue damage, skin infection, and even acute inflammatory lesions such as intra-articular infection.
