So far the cost of joint replacement is about 50,000 to 70,000 yuan, depending on the type of joints and regional hospitals, the cost varies slightly. At present, because of the national procurement, the price has dropped considerably. At present, the most commonly used joint replacement is hip and knee joint replacement, mainly for femoral head necrosis, and severe osteoarthritis of the knee. The approximate cost is 50,000 to 70,000 RMB, which varies depending on the material, brand and region of the joint. Arthroplasty is a more established procedure that involves replacing diseased tissue with a completely artificial material. Most of the surgical results of arthroplasty are satisfactory, and the main cost is still dominated by the cost of the joint itself. Generally speaking it is still recommended to operate as early as affordable when function is severely affected, to maximize the prevention of complications of prolonged bed rest (e.g., crashed pneumonia, venous thrombosis of the lower extremities, etc.). Currently the cost of artificial joints has gone down because of pooling, and it is recommended to consult your local hospital for specific prices.
