• A femoral component replaces the diseased portion of the femur (thigh bone).
• A tibial component replaces the diseased portion of the tibia (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 is recommended when arthritis affects more than one compartment of your knee. During the surgery, the bone and cartilage of the joint damaged by arthritis are removed and replaced with highly biocompatible metal and plastic components that form an artificial knee joint, or knee prosthesis. 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 effects5.
To reduce patients’ exposure to metals, Medacta has developed 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 tissues6.
This property makes SensiTiN-coated implants the preferred choice for treating patients who may present with the potential of metal hypersensitivity, and it is also considered a valid means of reducing the likelihood of hypersensitivity after knee replacement7,8,9.
