Your experience before surgery will be like that of most knee patients. But, unlike traditional knee replacement methods, with ROSA Knee and Partial 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. Due to our innovative technology, CT Scans can be optional, allowing for potential cost reductions to you.
ROSA® Robotic Technology
You’re unique, and so is your individual anatomy.
ROSA, the Robotic Surgical Assistant, is designed to help your specially-trained surgeon tailor the placement of your knee implant just for you.
Why ROSA Robotic Technology?
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
Getting a precise knee implant fit is important to your comfort and
overall experience following knee replacement surgery.
Driven by data
ROSA Robotics uses data collected before your surgery and during your 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 for and carry out a personalized surgery based upon your individual needs.
A Personalized Surgical Experience
The surgical procedure using ROSA Knee and Partial Knee is similar to traditional total and partial knee replacement, but with a robotic assistant. Your surgeon has been specially trained to use the system 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 still in the operating room the entire time and is making all of the decisions throughout your surgery.
During your procedure, the system 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 puts into place is executed as intended. Throughout your surgery, the system 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.
Following surgery, you will be hospitalized based upon 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.

While uncommon, complications can occur during and after surgery. Some complications include, but are not limited to, infection, blood clots, implant breakage, malalignment and premature wear, any of which can require additional surgery. Although implant surgery is extremely successful in most cases, some patients still experience stiffness and pain. No implant will last forever, and factors such as your post-surgery activities and weight can affect longevity. Be sure to discuss these and other risks with your surgeon.
There are many things that your surgeon may do to minimize the potential for complications. Your surgeon may have you see a medical physician before surgery to obtain tests. You may also need to have your dental work up-to-date and may be shown how to prepare your home to avoid falls.
The decision to have surgery is sometimes difficult. We hope that this information has helped you understand the ROSA Knee System so that you can make the best decision for yourself.
