What components are used for prostheses in knee replacement surgery?
There are different types of components that are used in artificial implants for knee replacement surgery-
- Femoral component: This part of the implant is directly attached to the femur and has a groove that allows the patellar component to slide while you are bending the knee joint.
- Tibial component: It is a flat two-piece metal and plastic part of the implant that is attached to the tibia. The plastic part acts as a cushion between the tibial and femoral components.
- Patellar component: It is a plastic dome-shaped component that is resurfaced to match the shape of the patella.
The plastic components of the implant are made of polyethylene, while the metal component is usually made of cobalt-chromium, titanium, zirconium, and nickel. Knee implants can be categorized into four categories based on what they are made of:
- Metal on plastic
- Ceramic on plastic
- Ceramic on ceramic
- Metal on metal
