In the complete replacement surgery of the knee, the damaged and causing pain parts are removed in the thigh bone, and the tube (leg bone). It is replaced by plastic and metal parts specifically designed for such cases.
Initially, the damaged bones and cartilage are cut and cartilage from the thigh bone. The end of the thigh bone is reinforced to allow the thigh metal parts to be overburde with the rest of the bone. The metal parts are connected at the end of the thigh bone by bone cement, which works as an adhesive.
The damaged bones and cartilage from the bone of the tubes are cut and reshaped, so that it is possible to install the metal parts of the bone of the tubes. The metal part of the bone of the bone is installed using a bone cement and a bite of polyethylene, and connected to the upper surface. This plastic bite will support the entire body weight, and it will allow the thigh bone to slip on the surface of the bone of the bone.
The new joint is formed by connecting the bone of the tubes (its new surface of polyethylene) and the thigh bone with its new metal part.
To ensure that the knee soap moves and slide smoothly on the new artificial knee, its rear surface is prepared and paste a plastic part of polyethylene by bone cement in this place.
Finally, the new component parts of the new joint are tested with the knee spread and their annexation.
The joint replacement with another artificial becomes necessary when a severe damage to the arthropic occurs or the large wear of it in it, increases the level of pain and discomfort in the knee to high levels. In addition to the inability of the knee to work well, for example, a shrinkage in the movement of the joint or the occurrence of a poor position of the knee joint.
Full replacement of the knee with artificial ones without using cement
We recommend a complete replacement of the knee, only if the knee rooms are severely damaged so that partial replacement is an inappropriate option. When the complete replacement of the knee is necessary, there are two available treatment options. One of the options includes “fixing the joint without using cement.
The installation without using cement provides a very fixed and long -term solution for the alternative knee joint, and even for the most active athletes. The rate of knee joint decreases over time, but this requires a longer rehabilitation period (6 weeks).
