Artificial joint replacement surgery refers to the use of metals, high molecular polyethylene, ceramics, and other materials to make artificial joint prostheses according to the shape, structure, and function of human joints, and implant them into the human body through surgical techniques to replace the function of the diseased joint, in order to alleviate joint pain and restore joint function.
Currently, knee joint replacement and hip joint replacement are the two most common types of artificial joint replacement surgery, and their ten-year success rate has exceeded90%, and even more8More than 0% of patients can normally use the implanted prosthesis for a long time20 years and even throughout their lives.
