What is the ROSA Knee system?

Meet ROSA, a robotic surgical assistant, developed by Zimmer Biomet. The ROSA Knee System’s precision robotic arm helps increase the success of your knee replacement surgery (compared to a traditional knee replacement) by assisting your Surgeon in the placement of your new implant.

I have a question about the ROSA Knee system

What are the benefits of the ROSA System for knee replacement?

A ROSA-supported knee replacement offers several benefits over a standard, non-robotic assisted total knee replacement. This includes:

  • Reduced likelihood of injury to the soft tissue surrounding your knee joint during surgery
  • Robotic surgery can be associated with reduced pain, so you may not need as much pain medication after your operation
  • Potentially a shorter stay in hospital and a quicker recovery, so you can get back to your daily activities
  • Better knee function after your surgery

How does the ROSA Knee System work?

Each individual knee is different; the ROSA Knee system uses hundreds of data points, which are collected before and during your surgery, to inform your Surgeon of specific details related to your unique anatomy.

This includes a camera and sensors, which are attached to your leg during surgery, to provide live information to your surgeon about the position of your knee. If your knee moves, ROSA can make automated minute adjustments to ensure that the plan designed by your surgeon is followed to exact detail.

Using this data to make more informed decisions, your Surgeon can plan for and carry out your surgery based on your individual needs.

Does the ROSA Knee robotic arm perform the surgery?

It's important to note that the ROSA cannot move on its own. It’s guided by the surgeon who will still carry out the entire procedure; the ROSA’s job is to assist them in placing your new knee joint.

Can any Orthopaedic Surgeon use the ROSA Knee System?

Only specially trained Orthopaedic Surgeons can use the robot.

Is the ROSA Knee System right for my total knee replacement?

Every individual’s situation is different and it’s important to find out which type of surgery is best for you. Your Surgeon will need to discuss whether this is the right option for you at an initial consultation.

Please contact our Private Patient team on 01580 363158 to book your appointment.

Can I get a knee replacement using the ROSA Knee System on my private medical insurance?

Please check with your insurance provider whether they would cover ‘Robotic-assisted knee replacement surgery’. If you gain an authorisation request, you can come to Benenden Hospital for treatment.
