What material is used for China prosthetic leg knee prosthesis
The main materials used for China prosthetic leg knee prosthesis are generally cobalt, chromium, molybdenum alloy and black gold prosthesis. Gaskets are generally highly cross-linked polyethylene.
China prosthetic leg knee prosthesis generally have three components, the femur, the tibial component, and the spacer between the tibia. These components are mainly made of cobalt, molybdenum, chromium alloy, and black gold prosthesis. Black gold prosthesis is a kind of prosthesis that exists between ceramics and metal. This kind of China prosthetic leg knee prosthesis is relatively wear-resistant, and the material is very smooth, which is closer to the physiological state of the human body.
Spacers between the femur and tibia are generally highly cross-linked polyethylene. Highly cross-linked polyethylene can be understood as a kind of plastic, but this kind of plastic is particularly wear-resistant and will not be damaged after 20-30 years of use. Although there are many materials for China prosthetic leg knee prosthesis, each material is safe to use in the human body.
Relatively speaking, black gold prosthesis is more expensive, but causes relatively few complications. Because the black gold prosthesis is more wear-resistant, it is more comfortable for patients to use. Some people have done relevant laboratory research, and black gold prostheses are less likely to be infected, because bacteria on such prostheses are not easy to parasitize and reproduce.
