Hip Replacement Implant Materials

There are a large number of hip implant devices on the market. Each manufacturer has different models but each style falls into one of four basic material categories:

metal on plastic (polyethylene or UHMWPE)

metal on metal (MoM)

ceramic on plastic (UHMWPE)

ceramic on ceramic (CoC)

These category names reference the materials used for the implant bearings. The stem and ball fit into and articulate against the cup or acetabulum. Each component can be made of one of several materials.

There is no consensus in the orthopedic community regarding the single “best” bearing or material. The choice generally comes down to your surgeon’s preference. Each surgeon has innumerable reasons for choosing one device over another, including his or her personal experience as well as tool and implantation method preferences.
