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.

Video transcript

The ROSA knee system stands for Robotic Surgical Assistant. Essentially, it's a tool that allows me to perform a knee replacement in a more accurate and balanced way. The ROSA system is used in surgery to try and make knee replacements as accurate as possible. The surgery itself involves making multiple cuts in the bones in order to precisely place a knee implant. And the use of the ROSA robot allows these cuts to be performed more accurately.

The other part of a knee replacement is that the soft tissues that support and move the knee need to be working in harmony with the replacement itself. And the ROSA system allows me to balance the soft tissues around the knee both before and after the surgery. Essentially, the robotic arm just places the cutting guides in the correct position. It then allows me to use my saw through that cutting guide to perform the cuts. So, no, we're not at the stage where we have robotic surgeons. This is essentially another tool to allow me to do the surgery more accurately.

Most knee replacements take somewhere between 45 minutes and an hour for me to perform. The ROSA surgery does have a few extra steps that add around another 10 or 15 minutes on top of that. One of the advantages of the ROSA system is that there is less damage to the soft tissues around the knee replacement. This means that you should have less pain following surgery and also your recovery should be slightly quicker.

The hospital stay will be one or two nights. You will be walking, fully weight bearing when you leave hospital, but you will be helped with a pair of crutches. Most people find that the recovery from a knee replacement does take a few weeks and it can be up to two or three months before you're feeling normal again. The ROSA system can be used in the vast majority of knee replacement surgeries. There are a few rare exceptions where it wouldn't be appropriate to use the ROSA when performing the operation. The best thing to do would be to speak to me or another one of my consultant colleagues who would be able to guide you as to whether or not it would be suitable in your case.

Benenden Hospital is a centre of excellence for orthopaedic surgery and it's exciting to see the hospital investing in this state-of-the-art, modern technology that will allow us to perform knee replacement surgery in a more accurate way. If you're considering having robotic-assisted knee replacement surgery, please get in touch with the Private Patient team here at the hospital.

FAQs

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.

What type of implant do you use? +

For total knee replacements, we use the Zimmer Biomet Vanguard® Knee System.

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.

What is mymobility®? +
