Hip Replacement: Does Implant Material Matter?

Fri, Nov 11, 2022

Hip replacement surgery has become a common procedure that can greatly alleviate joint pain and restore mobility for millions of Americans. By replacing a diseased or damaged part of the hip joint with an artificial joint, you can experience a significant reduction in pain and get back to walking without restraint.

An artificial joint, also known as an orthopedic prosthesis, is a device made of metal, ceramic, or plastic that is used to replace an arthritic joint. If you are planning to undergo hip replacement surgery, you may be wondering which hip replacement implant material is the best and whether it really matters.

Why Hip Implant Material Matters

The goal of hip replacement surgery is to help enable you to move without pain and limitations for as many years as possible. One of the key factors in attaining that goal is the integrity of the material used in the implant’s bearing surface – namely, the interface between the ball and socket of the prosthesis that is responsible for enabling movement. After all, it is the bearing surface that sustains the force of everyday movements. It must withstand considerable stress and friction, and be both biocompatible (non-toxic) to your body and wear-resistant. The more safe and more durable the material, the longer the life span and effectiveness of your hip implant.

In determining which implant material is likely to be the safest and longest lasting for you, your orthopedic surgeon will carefully assess factors such as your age, weight, activity level, and the extent of your joint damage, as well as whether you have a metal allergy. Each type of implant material has its advantages and disadvantages. Among the options available are:

  • Metal-on-polyethylene – This type of implant features a metal alloy ball and plastic socket or lining and is known for its durability and performance. On the downside, metal-on-polyethylene implants can produce debris, which can lead to osteolysis, a condition in which bone tissue is destroyed, which can lead to eventual implant failure.
  • Ceramic-on-ceramic – Newer ceramic materials are stronger and less brittle and may wear out more slowly or over a longer period of time. They are, however, more expensive and can create a squeaking sound in some cases, or the surfaces can potentially break or chip, as opposed to wearing down gradually over time.
  • Ceramic-on-polyethylene – Made of a ceramic ball and a plastic socket or lining, this type of implant is a high-strength material that is also smooth, scratch-resistant, and low-friction. As such, it is regarded as an excellent alternative to metal and plastic implants and may have fewer risks than a ceramic-on-ceramic bearing.
