ROSA® Robotic-Knee Technology

Getting a precise knee implant fit is important to your comfort and overall experience following knee replacement surgery. You’re unique, and so is your individual anatomy. ROSA (Robotic Surgical Assistant) is designed to help our orthopaedic surgeons tailor the placement of your knee implant. The ROSA knee system 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, our surgeons are able to plan for and carry out a personalized surgery based upon your individual needs.

Advantages of the ROSA® robotic knee replacement

Being a minimally invasive approach, the ROSA® knee system offers the following benefits:

• Smaller incisions with reduced scarring and minimal blood loss
• Less post-operative pain
• Shorter hospital stay and recovery period
• Quicker return to daily activities
• Lower incidence of complications
• Precise placement of the implant
• Reduced injury to adjacent tissues
• Increased longevity of the implant

Before surgery

Your preoperative experience will be like that of most total knee patients. But, unlike traditional knee replacement methods, with ROSA Knee, 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 ROSA Knee is similar to traditional total knee replacement, but with a robotic assistant. Our orthopaedic team has been specially trained to use ROSA Knee 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 our surgeon prompts it to. Our surgeons remain in the operating room the entire time and is making all of the decisions throughout your surgery. During your procedure, ROSA Knee 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, ROSA Knee 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

Following surgery, you will be hospitalized based on the recovery plan your surgeon decides is best for you. This hospitalization may range from one to three days. Recovery time varies, but most people should be able to drive after two weeks, garden after three to four weeks, and golf after six to eight weeks. Your surgeon will tell you when and what activities you can return to, and what activities to avoid.

Is it time for knee replacement?

That’s a question you and your orthopaedic surgeon will have to answer together. But when knee pain is so bad it actually interferes with the things you want or needs to do, the time may be right. Here are some signs to consider:

• Medication and using a cane just aren’t delivering enough relief
• Pain is keeping you up at night
• Your knee aches during and after exercise
• Your knee stiffens up sitting in a car or a movie theater
• You are no longer as mobile as you’d like to be
