Premier Health Offers Robotic-Arm Assisted Joint Replacement

Premier Pulse     December 2020

Premier Health announced the implementation of two robotic arm-assisted joint replacement technologies that will enable surgeons to cater to the individual needs of patients. Mako SmartRobotics™ will be offered at Miami Valley Hospital North for hip and knee replacement, while Zimmer Biomet’s ROSA® Knee will be implemented at Miami Valley Hospital North, Miami Valley Hospital South, and Atrium Medical Center for knee replacement.

Mako SmartRobotics™ combines three key components - 3D CT-based planning, AccuStop™ haptic technology and insightful data analytics - into one platform. The 3D CT-based software lets the surgeon know more about a patient’s anatomy and helps the surgeon create a personalized joint replacement surgical plan before surgery. During surgery, the surgeon can validate the plan and make necessary adjustments while guiding the robotic arm to execute the plan. For patients, this may mean less pain, less need for opiate analgesics, less need for inpatient physical therapy, shorter hospital stays, improved knee range of movement, and greater soft tissue protection compared to manual techniques.

The ROSA® Knee System supports surgeons in performing total knee replacement with features to assist with bone resections, as well as assessing the state of the soft tissues to facilitate implant positioning intraoperatively. A precise knee implant fit is important to comfort and overall experience following knee replacement surgery. ROSA® Knee uses data collected before and during surgery to inform the surgeon of many details related to a person’s unique anatomy that might affect the implant fit. By using this data to make more informed decisions, a surgeon can plan for and carry out a personalized surgery based upon individual needs. The preoperative experience will be like that of most total knee patients. But with ROSA® Knee, unlike traditional knee replacement methods, a series of X-rays can be used to create a three-dimensional (3D) model of a patient’s knee anatomy. This 3D model helps the surgeon plan many specifics of the knee replacement prior to surgery.

The surgical procedure using ROSA® Knee is similar to traditional total knee replacement, but with a robotic assistant. Surgeons have been specially trained to use ROSA® Knee in order to personalize the surgical approach for a patient’s unique anatomy. The robot does not operate on its own and does not move without a surgeon’s prompting. The surgeon remains in the operating room throughout the procedure, making all decisions. During a procedure, ROSA® Knee utilizes a camera and optical trackers attached to the leg to know exactly where the knee is in space.
