ROSA Knee Robotic Technology

A Personalized Approach to Your Knee Replacement

ROSA Total Knee Replacement System

Summit Medical Center is excited to offer Zimmer Biomet’s ROSA® Knee System, which brings together robotic technology and 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. It includes features to assist with bone resections and assessing the state of the soft tissues in order to facilitate implant positioning intraoperatively.

Data provided by ROSA Knee assists with complex decision making and enables surgeons to use computer software technology to control and move surgical instruments, allowing for greater precision and flexibility during procedures.

You’re unique, and so is your individual anatomy. That’s why Summit Medical Center 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! 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 details related to your unique anatomy that may affect your implant fit. This allows your surgeon to plan and execute a surgery personalized based on 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.

Healthy Knee vs. Arthritic Knee

The ROSA Procedure

Before 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.

During 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 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.


Following surgery, you will be hospitalized based upon the recovery plan your surgeon decides is best for you. Your hospital stay in one of our private patient rooms 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.
