Robot-Assisted Knee Replacement Surgery
Robot-assisted knee replacement surgery is an option for patients when a surgeon finds that traditional treatment options fail to provide relief. Surgeons may recommend total knee replacement using ROSA® (Robotic Surgical Assistant) technology, which is designed to help tailor the placement of knee implants specifically to your unique anatomy.
What is ROSA knee replacement?
Robot-assisted knee replacement surgery is an alternative to traditional knee replacement procedures. Your orthopedic surgeon may choose to use ROSA technology to find a comfortable fit for your new knee implant. Surgeons are in complete control of the robot's movements during surgery, using the robot to gather data about your knee and make precise decisions.
Who can have robot-assisted knee replacement?
Any person in need of a total knee replacement could be eligible for robot-assisted knee replacement surgery. Your orthopedic surgeon will determine whether ROSA robotic technology is right for you based on risk, complications and your unique anatomy.
How does robotic knee technology work?
A surgeon may first use a series of X-rays to create a 3D model of your knee. The surgeon will use ROSA technology as an assistant to personalize the replacement experience to your specific needs.
It is important to know that the ROSA knee surgical robot does not operate on its own. It does not move unless your surgeon prompts it to. Your surgeon is in the operating room the entire time and is making all the decisions throughout your surgery.
Benefits and risks of robot-assisted knee surgery
Traditional knee replacement methods are clinically effective, but ROSA technology can improve your surgeon's ability to position your implant to fit your specific anatomy. A precise fit may improve comfort and the overall experience.
While uncommon, complications may include, but are not limited to:
- Blood clots
- Displaced alignment
- Implant breakage
- Premature wear
Some patients may experience stiffness and pain after surgery. Factors like postsurgery activities and weight can affect the life span of your implant. It is important to discuss these factors and risks with your orthopedic surgeon prior to surgery.
What happens during robot-assisted knee surgery?
ROSA technology uses a camera and optical trackers like a GPS that are attached to your leg to track your knee and the implant. The robot provides your surgeon data about your knee, making them aware of slight movements so they can adjust for the right fit.
After surgery, you will be hospitalized based upon the recovery plan your surgeon determines is best. Hospitalization can range from 0 to 2 days. Recovery time can range between 2 and 8 weeks or longer depending on the activity desired. Your surgeon can provide information about approximate recovery time, as well as activities to avoid during the recovery process.
