Hip Replacement Options

There are two major types of artificial hip joint:

Cemented vs. Cementless Components
In total hip joint replacement, the femoral component can be secured to your body in one of two ways: using bone cement as a grout to fix the components to your bone, or using a "cementless" component that is specially designed to allow your own bone to grow into the surface of the implant. Which component your Surgeon chooses for you will depend on a variety of factors, including the condition of your bone.


A cemented hip replacement usually lasts for at least 10 years, after which it may need to be replaced. Artificial joints that are fixed directly to the bone may last even longer.


Hip Joints
There are many different types of artificial hip parts made of metal, porcelain or plastic.


Polyethylene, Ceramic, or Metal

Your Surgeon has several choices available in articulating surfaces. An articulating surface is where the motion of the joint actually occurs. In the case of the hip, it is where the head of the femoral component meets the acetabular socket. In order to provide smooth motion, the articulating surface must be able to withstand certain activities. Currently, polyethylene, metal, and ceramic are the most common articulating configurations offered. Each has its advantages and specific benefits that your Surgeon can match to your needs.


Polyethylene

Polyethylene (plastic) is an excellent material for hip articulation. It has been used in orthopaedic implants for decades. Newer methods of manufacturing polyethylene components, invented and patented by Biomet, have resulted in significant intermediate-term improvements in durability.


Ceramic-on-Ceramic

Ceramic implants are another option for total hip replacement. They have shown excellent wear properties, making them suitable for long-term wear resistance.


Metal-on-Metal

Metal hip implants are designed to withstand the demands of active lifestyles. These implants feature a metal ball that glides in a metal cup, which provides wear resistance.  The large femoral head allows a good range of motion.
