Robot Assisted Hip Replacement

Hip replacement surgery can be performed with the assistance of a Mako robotic arm. Robotic assisted hip replacements can be more personalised and precise than conventional surgery.

Who Should Consider Robotic Assisted Hip Replacement?

A total hip replacement is most often needed when the joint has been worn down by arthritis, but it can also be performed when there are other reasons for pain and mobility problems, such as a bone deformity or injury. The damaged bone can then be replaced with a prosthetic hip in order to relieve these symptoms. The procedure can be performed with the aid of a robotic arm in order to ensure the best results. Robotic arm assistance can be particularly beneficial if you have unusual hip anatomy or it is important to preserve as much of your bone as possible.

The Procedure

The procedure for a robotic arm assisted hip replacement is similar to a conventional hip replacement. An incision will be made over the joint. The damaged bone will then be removed and the artificial hip attached to the thigh bone and pelvis. The difference is that the surgeon will use a Mako robotic arm to perform these actions with the utmost precision. The operation will be carefully planned and tailored to your needs using a 3-D model of your hip created from CT scans. The surgeon will guide the robotic arm through the planned procedure, but will be able to make adjustments as necessary during the operation. You will need to use crutches for two to six weeks after the hip replacement and your doctor will recommend an exercise programme to help you to rebuild your mobility.

Risks and Benefits

If you are considering robotic assisted surgery for your hip, it is important to understand the risks and benefits of the procedure:

  • Surgery always carries some risks, such as infection, bleeding, blood clots and nerve damage. Other risks specific to total hip replacement include dislocation and leg length discrepancy. The chances of serious complications happening is small, but your surgeon will explain them in detail before the operation.
  • Artificial hip joints should last for at least 15 years, but may need to be replaced at some point. However, the failure rate is believed to be lower with robotic assisted surgery as the implants will be in the optimum position.
  • Hip replacement surgery can improve your mobility and relieve pain in your joint
  • Robotic assisted hip replacement is a more personalised procedure than conventional hip replacement surgery
  • The careful planning and use of the robotic arm enables diseased or damaged bone to be precisely removed while preserving as much of the healthy bone as possible
  • The robotic arm can more accurately position the implant in order to ensure a good fit for your joint which should help with your mobility
