ROSA KNEE SYSTEM
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 designed to help your specially trained surgeon tailor the placement of your knee implant just for you. Here, we will explain what makes the ROSA Knee System unique, what to expect preoperatively, what will happen with ROSA Knee during surgery and what to expect after your surgery.
ROSA KNEE Robotic Technology
Getting a precise knee implant fit is important to
your comfort and overall experience following knee
replacement surgery. ROSA Knee 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, your surgeon
is able to plan for and carry out a personalized
surgery based upon your individual needs.
Arthritis in the knee joint
The knee is a hinge joint formed by the tibia (shinbone), femur
(thighbone), and patella (kneecap). The ends of the bones in the knee
joint are covered with cartilage, a tough, lubricating tissue that helps
cushion the bones during movement.
Osteoarthritis, the most common form of arthritis, is a wear-and-tear
condition that destroys joint cartilage and bone. It typically develops
after years of constant motion and pressure in the joints. As the cartilage
continues to wear away, the joint becomes increasingly painful and
difficult to move. If conservative treatment options fail to provide relief,
your surgeon may recommend total knee replacement using ROSA
Knee robotic technology.
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.
The surgical procedure using ROSA Knee is similar to traditional total
knee replacement, but with a robotic assistant. Your surgeon 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
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.
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 this has helped you
understand the ROSA Knee System so
that you can make the best decision for
yourself. This information is not intended
