• A femoral component replaces the diseased portion of the thigh bone.
• A tibial component replaces the diseased portion of the shin bone.
• A plastic insert between the femoral component and the tibial baseplate replaces the cartilage function allowing the thigh and shin bones to slide on each other.
Total knee replacement surgery is recommended when arthritis affects more than one compartment of your knee, you have ligament deficiency or damage, or you require correction of intra-articular deformities.
During total knee replacement surgery, the entire surface of the femur and tibia are replaced with metallic and plastic components. The undersurface of the kneecap may also be replaced with an implant made of plastic.

In knee replacement surgery, alternative options can reduce the risk of hypersensitivity after knee replacement and the occurrence of undesired effects 5.
To reduce patients’ exposure to metals, Medacta has designed SensiTiN coating, which is made of a highly biocompatible material characterized by a gold-yellow color.
SensiTiN coating firmly attaches to the surface of the knee replacement and acts as a barrier between the implant and the surrounding tissues 6.
This property makes SensiTiN-coated implants the preferred choice for treating patients with metal hypersensitivity, and it is also considered a valid means of reducing the likelihood of hypersensitivity after knee replacement 7,8,9.
