Does the ROSA Knee robot perform my knee replacement on its own?

No. The surgical procedure using the ROSA Knee robot is similar to traditional total knee replacement (TKR), but with a robotic assistant. 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 the decisions throughout your knee surgery.

What risks are involved with robotic-assisted knee replacement?

It is important to understand the risks involved. There are potential complications both during and after, whether robotic assistance is used or not. Generally, these include infection, blood clots, pneumonia, implant loosening, nerve damage, bone fracture and implant breakage; any of which can require additional surgery. While joint replacement is generally successful in lowering pain levels and increasing mobility, some patients will continue to experience pain and your doctor may permanently restrict certain activities that could damage and wear out your new knee parts. Ask your doctor to explain other surgery risks.

Will my knee implant fit my unique anatomy?

Getting a precise knee implant fit is important to your comfort, recovery and overall experience following knee replacement surgery. ROSA Knee technology uses data that enables your surgeon to execute a personalized surgery, allowing for an optimal implant fit based on your needs.

Overview

Understanding Robotic-Assisted Knee Replacement

You’re unique, and so is your individual anatomy. That’s why Zimmer Biomet offers ROSA^® Knee robotic technology. ROSA, which stands for Robotic Surgical Assistant, is a knee replacement technology that’s designed to help your surgeon tailor the placement of your knee implant just for you.

When is Robotic-Assisted Surgery Used?

In situations where precision and personalization are particularly beneficial, your surgeon may recommend robotic-assisted knee replacement surgery using ROSA Knee.

ROSA Knee uses data collected before and during surgery to inform your knee replacement 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 can plan for and carry out a personalized knee replacement surgery based on your individual needs.

How Does Robotic Knee Replacement Work?

Before Knee Replacement Surgery

Your experience will be like that of most total knee patients. But, unlike traditional knee replacement methods, with ROSA robotic-assisted knee replacement, a set of X-rays may be used to create a 3D model of your knee. This 3D model will enable your surgeon to plan many specifics of your knee replacement before your surgery.

During Knee Replacement Surgery

The ROSA Knee robotic technology uses trackers to know exactly where your knee is in space. This helps ensure that the plan your surgeon put into place is executed as intended. Throughout surgery, the ROSA Knee robot provides your surgeon with data. This information, combined with your surgeon’s skill, helps them know how to position your implant for the right fit based on your unique anatomy.

After Surgery

You may return home the same day or remain in the hospital for one to three days, depending on the recovery plan your surgeon decides is best for you. Recovery time varies, but most people should be able to drive after two weeks and back to moderate activity after three to four weeks.

Benefits of Robotic Knee Surgery

Why Should You Consider a Robotic Total Knee Replacement (TKR)?

Robotic-assisted knee replacement with ROSA Knee offers a variety of benefits, including, but not limited to, precise and accurate implant placement.^6,7 Learn about all the benefits here.

Faster recovery with earlier improvements in range of motion and knee function compared to traditional total knee replacement^1-3

Less exposure to radiation compared to CT-based robotic knee replacement^4,5

Improved accuracy and implant positioning compared to traditional knee replacement, which may lead to improved patient satisfaction^6,7
