Minimally invasive robot assisted knee replacement surgery
ROSA® Knee System
What is the ROSA Knee System?
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. The ROSA (Robotic Surgical Assistant) is designed to help our orthopedic surgeons tailor the placement of your total knee replacement. 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.
What are the benefits of the ROSA robotic total 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
- Improve quality of life by regaining strength and mobility
- Lower incidence of complications
- Precise placement of the implant
- Reduced injury to adjacent tissues
- Increased longevity of the implant
While generally successful, some patients will continue to experience some pain and varying levels of activity restrictions. Always talk to your orthopedic surgeon about all treatment options, as well as the associated benefits and risks.
Overview of the ROSA knee robotic surgery
Zimmer Biomet’s ROSA® Knee System, which brings together robotic technology with industry-leading knee implants to help surgeons personalize surgical procedures for their patients. ROSA Knee is a robotically-assisted surgical system designed to help perform total knee replacement surgery
What happens before the ROSA Knee Replacement 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.
What to expect during the ROSA Knee Replacement Surgery?
The surgical procedure using ROSA Knee is similar to traditional total knee replacement, but with a robotic assistant. Our orthopedic 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.
What is recovery like after the ROSA Knee Replacement 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 orthopedic 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:
- Makes everyday activities painful
- Pain is keeping you up at night
- Is not relieved by physical therapy or other treatments for a reasonable period of time
- Is accompanied by chronic knee inflammation/swelling and stiffness that doesn’t improve with rest
Frequently Asked Questions
Arthritis is inflammation of your joint that develops over time. Osteoarthritis is the most common form of arthritis and causes the cartilage (shock absorber) to gradually wear away over time. This results in bone rubbing on bone, causing pain.
Your surgeon is still 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. 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.
How long a knee replacement will last varies from patient to patient. It depends on many factors, such as the patient’s physical condition, activity level and body weight, and the surgical technique. Replacement joints are not as strong or durable as a natural, healthy joint, and there is no guarantee that an artificial joint will last the rest of a patient’s life. All knee replacements may need to be replaced at some point.
Compared to open surgery, there is less pain with the ROSA Robotic Surgery because the surgeon makes small incisions and the instruments allows them to access hard-to-reach areas without disturbing the surrounding healthy tissue. Less pain also means the patient needs less pain medications, which may cause side effects like nausea, constipation, drowsiness and many others.
