Advances in knee replacement surgery

Recent improvements in knee 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, and
  • Shorter post-operative rehabilitation, so you can resume everyday activities sooner.

Read some information on computer assisted knee surgery here - you may wish to discuss it with your orthopaedic surgeon.

Computer assisted knee surgery

Computer assisted knee surgery

With computer-assisted knee surgery your surgeon can create a model of your knee 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 knee surgery?

The aim of computer-assisted knee surgery 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 knee replacement5
  • Reduced risk of future dislocation due to correct aligment.1,2

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

Robotic enabled knee surgery

Robotic enabled knee surgery

The use of robotic technology in the field of knee replacement surgery is rapidly growing. Robotic replacement surgery can allow for more consistently reproducible precision in terms of knee replacement surgery.

What are the benefits of robotic enabled knee surgery

Robotic knee surgery may:

  • Facilitate ideal implant positioning that can result in a more natural feeling knee following surgery
  • Result in a more rapid recovery and shorter hospital stay than traditional knee replacement surgery
  • Promote a more rapid relief from pain and return to daily activities




Partial Knee Resurfacing Surgery

Partial Knee Resurfacing Surgery 

A robotic arm assisted partial knee resurfacing procedure may consist of either a unicompartmental or bicompartmental knee replacement, which basically means that only part of the knee joint is being replaced. Stryker's Robotic-Arm Assisted SurgeryTM is designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA). This procedure uses an interactive robotic arm, which allows for optimal and accurate placement of your implant. During the procedure, the diseased portion of the knee is resurfaced, sparing the healthy bone and surrounding tissue. An implant is then secured in the joint to allow the knee to move smoothly again.

During surgery, Stryker's Robotic-Arm Assistance provides the surgeon with real-time visual, tactile and auditory feedback to facilitate optimal joint resurfacing and implant positioning. It is this optimal placement that can result in more natural knee motion following surgery.

Partial knee replacement surgery usually takes one or two hours and hospital stays average anywhere from one to three days, but may last longer depending on individual patient factors.
