Old Sir Wu's knee preservation surgery has inspired extensive imaginative ideas from Robert and Director Gao.
In the future, it may be possible to use cultivation techniques or 3D printing technology to manufacture qualified knee joint cartilage, and then carry out cartilage replacement, similar to a joint replacement surgery, replacing all worn-out and scrapped joint cartilages.
Like replacing the tires on a car, the elderly can have youthful joints.
After all, artificial joints solve the problem of pain, but can't compare with normal human knee joints in terms of functionality.
Currently, many teams are conducting research in this area, but they are all in the initial stages. Both cultivated and 3D printed cartilage are far from real cartilage, and therefore are basically ineffective.
Strictly speaking, real cartilage has not yet been cultivated or printed.
Robert and Director Gao, these two international brothers, are around the computer, still watching the surgical video.
