PRP therapy, known as Platelet Rich Plasma Therapy in Chinese, is a new type of treatment, which is used to treat knee injuries mainly by injecting autologous serum for therapeutic purposes. The cost of this method is variable, ranging from 9,000 to 20,000 yuan, depending on the individual’s situation, local charges and the grade of the hospital. In general, the cost of using autologous serum injections to treat joint diseases ranges from $9,000 to $20,000 at one time, but different hospitals charge different fees and the grade of the hospitals will also vary, so you can’t make a generalization. For more serious joint diseases, the cost is relatively higher when autologous serum injection is used for treatment. Moreover, some hospitals have higher grades and the level of charges will be raised, so the cost will be increased appropriately, and you should consult your local hospital for details. Autologous serum injection is a certain risk, so it must be carried out under the guidance of a professional physician to avoid unauthorized use.
