There is no such thing as a fake knee. The normal procedure is a knee surface replacement for severe osteophytes, osteoarthritis and other diseases, or a knee prosthesis replacement surgery, which currently costs about 50,000 yuan in clinical practice. The cost of this surgery is about$50,000. It is also very effective for patients with advanced osteophytes and osteoarthritis that cause severe pain and limited movement and affect their daily life. After the surgery, there is no significant pain in the incision, and the patient can start functional rehabilitation exercises on the floor and gradually return to normal daily life level. Of course, the cost is also related to the quality of the prosthesis, if you use imported good quality may be based on the 50,000 yuan, to add a 10,000-20,000 yuan, or even the prosthesis to take imported better to add a 30,000-50,000 yuan cost.
