On the left, the femur cap is visible, while the right component is fitted into the tibia.This prosthetic knee joint was ill-fitting and causing pain and discomfort for the patient, as well as being quite outdated. It was removed and replaced by a newer model composed of titanium, a tougher and sturdier material, which allowed for more stability and comfortable movement.The prosthesis currently in place owes its lustrous appearance to the fact that it is plated with gold. This is not due to a need for surgically implanted swag, but rather for gold’s extreme resistance to corrosion, erosion and high biocompatibility which make it suitable for implants such as these. .
