Total knee arthroplasty, performed daily in specialized facilities, involves the removal of worn cartilage on the articular surfaces of the femur and tibia by means of techniques to prepare the bone that will house the components and the positioning of the femoral and tibial components on the two surfaces, so that they “cover” the old surface.
The knee is a joint that makes flexion and extension movements possible. The three bone segments that make up the joint are: the femur, tibia and patella. In its distal portion the femur is composed of two different structures, the condyles (medial and lateral), with a convex surface, which are free to slide and roll on the two tibial hemiplateaus.
Knee replacement is the only possible treatment for advanced joint degeneration.
This involves the surgical replacement of the articular surfaces of the femur and tibia with artificial components in order to reproduce all the movements of the arthritic joint as faithfully as possible.
The first classification of the prosthetic models currently used concerns the number of joint compartments to be replaced with the prosthesis, depending on the type of arthrosis affecting the patient.
The total prosthesis is undoubtedly the most widely used model and the one with the highest probability of durability over time.
