ROSA Robotics for Knee Replacement

You’re unique, and so is your individual anatomy. ROSA® Robotics technology is designed to help your specially-trained surgeon tailor the placement of your knee implant just for you. ROSA, Robotic Surgical Assistant, is available at Community Hospital East.

About ROSA KNEE Robotic Technology

Getting a precise knee implant fit is important to your comfort and overall experience following knee replacement surgery. The ROSA Knee robot uses data collected before and during surgery to inform your surgeon of many details related to your unique anatomy that may affect your implant fit. By using this data to make more informed decisions, your surgeon is able to plan and carry out a personalized surgery based upon your individual needs.

Benefits of Robotic Knee Replacement

  • Patients can potentially save money on their ROSA robotic surgery as the system does not require the use of CT scans1
  • Less exposure to radiation2
  • Increased accuracy compared to traditional knee replacement3–4
  • Better implant positioning, which can result in a more natural-feeling knee after surgery5
  • Potential for better long-term satisfaction and outcomes6

What to Expect

ROSA robotic surgical assistantBefore Surgery

Your preoperative experience will be like that of most knee replacement patients. But, unlike traditional knee replacement methods, with ROSA Robotics, a series of x-rays may be used to create a three-dimensional (3D) model of your knee anatomy. This 3D model will enable the surgeon to plan many specifics of your knee replacement prior to your surgery.

During Surgery

The surgical procedure using the ROSA robot is similar to traditional knee replacement, but with a robotic assistant. Your surgeon has been specially trained to use the ROSA robot in order to personalize the surgical approach for your unique anatomy. It’s important to understand that the robot does not operate on its own. That means it does not move unless your surgeon prompts it to. Your surgeon is in the operating room the entire time and is making all of the

decisions throughout your surgery. During your procedure, ROSA utilizes a camera and optical trackers attached to your leg to know exactly where your knee is in space. Think of it like a very detailed global positioning system (GPS) that you might use in your car. If your leg moves even a fraction of an inch, the robot can tell and adjusts accordingly. This helps ensure that the plan your surgeon put into place is executed as intended. Throughout your surgery, the ROSA robot provides your surgeon with data about your knee. This information, combined with your surgeon’s skill, helps them know how to position your implant based on your unique anatomy.

After Surgery

Recovery time varies and will depend on your unique needs and the recovery plan that you and your surgeon have agreed on. Your surgeon will tell you when and what activities you can return to, and what activities to avoid.
