Recently, Xiao Wang from Zibo said that his father was engaged in agricultural work all his life, but as he grew older, his health got worse and worse, especially his knee joint hurt all the time, and now he developed before the operation, but he does not know what this kind of material is good. For this reason, he came to the provincial hospital to consult with me at the clinic. What are the differences between total knee replacement materials? How can I choose? Today I will give you popular science.
When people get older, they have certain joint problems. It can be said that total knee arthroplasty is the gospel of knee diseases. This method can not only save the function of the patient's knee joint, but also help the patient regain mobility relieve pain. However, with the continuous development of science and technology, artificial prosthesis materials are becoming more technologically advanced.
Are materials different for total knee replacement?
There are still some differences in materials for total knee arthroplasty in clinical practice.
Currently, total knee replacement materials mainly include metal and ceramics.
Common knee replacement material is metal
The most commonly used knee replacement material is metal, but there are other types such as stainless steel alloy and titanium alloy. But there are certain differences in the properties of each metal, such as strength, durability, and biocompatibility. At present, the most suitable for the human body is an artificial prosthesis made of titanium alloy, this material has high fatigue strength and does not cause inflammation and poisoning reactions.
Complete knee replacement material - ceramic prosthesis
The other is a ceramic artificial prosthesis. It exists in the form of oxides in artificial joints. The surface of artificial prostheses made from this material has good stability, good biocompatibility, and is difficult to oxidize and degrade. In addition, the corrosion and fatigue resistance of artificial prostheses made from this material is much better than products made from other materials, which is why many patients choose this material for artificial joint replacement.
Due to the complexity of the knee joint, in order to better help knee disease patients recover and prolong the life of artificial prostheses, the medical community is currently investigating ceramic products with metal surfaces.
In addition to the above items, joint prostheses can also be imported or domestically produced.How to choose material for total knee replacement?
Clinically, when a patient chooses a prosthesis, the operator must still be the leader, and the prosthesis must be selected strictly according to the type of knee joint deformity and the integrity of the soft tissues.
