Read about all of the different types of hip replacement implants and knee replacement implants available and see how they are rated by clicking on the pictures below:
Each section has an ODEP rating listed. This is an rating issued by a group of medical professionals. The number refers to the minimum number of years that the implant has been around ( 3 being a low number of years and 10 being the highest) and the letter refers to the quality of published data that supports the implant (a. being the best c. being the worst). So far, only hips have been rated by this regulatory body.

What are the components of a knee implant in a total knee replacement ?
The three components of knee implants are : -
The tibial component has two elements and replaces the top of the shin bone (tibia). This prosthesis is made up of a metal tray attached directly to the bone and a plastic spacer that provides the bearing surface.
The femoral component replaces the bottom of the thigh bone (femur). This component also replaces the groove where the patella (kneecap) sits.
The patellar component replaces the surface of the knee cap, which rubs against the femur. The kneecap protects the joint, and the resurfaced patellar button slides smoothly on the front of the joint. This may or may not be replaced depending on the condition of the patient.
Knee Implant FAQs
Which bones are replaced or resurfaced in a total knee replacement ?
Depending on your specific case, up to three bone surfaces may be replaced during your total replacement of the knee.
They include : -
the lower ends (condyles) of the thighbone
the top surface of the shinbone
the back surface of the kneecap.
How is a knee implant affixed in the body ?
Knee implant systems are affixed in the body in one of three ways : -
Cemented with bone cement: A special type of acrylic bone cement may be used to secure some or all of the implant components to the bone. The bone cement takes about 15 minutes to set.
Cementless (biologic ingrowth): Implant components using cementless implantation have a special porous coating that allows tissue to grow into it for fixation.
Combination: In some cases, your surgeon may choose a combination of cement and cementless attachment, depending upon the implant components and the condition of the bone around the knee joint.
The decision as to whether to use a cemented or cementless component depends upon many factors, including the intended use of the product, surgeon philosophy and the patient%u2019s condition.
