Computer assisted hip surgery

With computer-assisted hip surgery your surgeon can create a model of your hip and plan accordingly for surgery. He or she is able to correct potential misalignment during the surgery, and better visualise your anatomy – this is particularly important when minimally invasive surgical techniques are used.

What are the benefits of computer-assisted hip surgery?

The aim of computer-assisted hip surgey is to help your surgeon work more efficiently and align your implant more accurately to your unique anatomy, so you can benefit from:

  • Reduced joint wear, making your implant last longer1,2
  • Shorter rehabilitation time3
  • Smaller incision4
  • Less blood loss compared to a standard hip replacement5
  • Reduced risk of future dislocation due to correct aligment.1,2

Talk to your surgeon about the types of joint surgery appropriate for you and the risks associated with any surgery.

Advances in hip replacement surgery

Recent improvements in hip replacement surgery technology and techniques have led to better outcomes, such as:

  • Reduced wear on the replacement joint, which extends the life of your implant,
  • Shorter post-operative rehabilitation, so you can resume everyday activities sooner.
