Zimmer Biomet received U.S. Food and Drug Administration (FDA) 510(k) clearance of the ROSA Hip System for robotically-assisted direct anterior total hip replacement. ROSA Hip is the fourth robotic system introduced by Zimmer Biomet and adds to the Company's comprehensive ROSA Robotics portfolio, which includes the ROSA Knee System for total knee arthroplasty, ROSA Partial Knee System for partial knee arthroplasty and ROSA ONE for neurosurgical and spine procedures. ROSA Hip is the newest addition to ZBEdge, Zimmer Biomet's suite of integrated digital and robotic technologies purposefully engineered to deliver transformative data-powered clinical insights, shared seamlessly across the patient journey, and with the goal of improving patient outcomes.
 
"We're excited to announce the FDA clearance of ROSA Hip, and to now offer one of the most comprehensive orthopedic robotic solutions through a single, multiple application platform," said Ivan Tornos, COO at Zimmer Biomet. "As an integrated component of our ZBEdge Connected Intelligence Suite, ROSA Hip advances our vision to translate pre-, intra-and post-operative data into actionable clinical insights to inform personalized care decisions."
 
Designed to seamlessly adapt to a surgeon's existing workflow, ROSA Hip aims to assist direct anterior surgeons with preparation, positioning and component impaction, while intra-operatively quantifying cup orientation, leg length and offset.  Intra-operative data collected by ROSA Hip is combined with pre- and post-operative data collected by mymobility with Apple Watch, a proprietary remote care management platform, and it is seamlessly consolidated and analyzed by OrthoIntel Orthopedic Intelligence Platform, which is designed to uncover new clinical insights throughout the episode of care and help surgeons and care teams make informed decisions and optimize patient care.
 
ROSA Hip is designed for compatibility with multiple implant systems, including the Avenir Complete Hip System, an evolution of the Avenir Hip Implant that has a clinically-proven heritage of over 10 years.^1,2,3,4 The Avenir Complete Hip System together with the G7 Acetabular System, a comprehensive offering of stems, shells and liners, aims to deliver greater operative flexibility and surgical excellence to help surgeons address the distinct needs of each patient.
 
"ROSA Hip will allow surgeons to retain complete control over case planning and execution, while providing real-time data and visualization tools," said Atul Kamath, M.D., Director, Center for Hip Preservation at the Cleveland Clinic and a ROSA Hip developer surgeon. "Even surgeons who are new to robotic-assisted surgery can easily tailor ROSA Hip to adapt to their own workflow. The robotic platform provides support during component positioning, cup impaction and other critical steps of an anterior approach total hip replacement. By reducing the intra-operative variability and inconsistency, this new technology has the potential to give surgeons and their patients greater confidence in seeking value in contemporary total hip replacement."
 
ROSA Hip is a fluoroscopy-based tool designed for surgeons who use the direct anterior approach, a minimally invasive approach to performing total hip replacement surgery. In addition to providing robotic assistance to guide accurate acetabular component orientation⁵, as well as intra-operative assessment of leg length and offset, the application allows surgeons to create a personalized surgical plan through the use of ONE Planner™ Hip. This pre-operative planner features a spinopelvic mobility assessment tool if both a sitting and standing lateral X-ray are provided with the anteroposterior (AP) X-ray, together with an auto-plan function that allows surgeons to potentially create a pre-operative plan within five minutes. ROSA Hip may also help improve procedural efficiency with a simplified set-up that doesn't require pins or reference arrays and the convenient option to use X-ray imaging instead of CT scans.
