Hackensack University Medical Center is the first hospital in New Jersey and the first in the northeastern United States to perform total knee-replacement surgery utilizing the Zimmer Biomet’s Knee Robot called the Robotic Surgical Assistant or ROSA.
Harlan Levine, M.D. and Gregg Klein, M.D., are orthopedic surgeons at Hackensack University Medical Center and two of the developers of the ROSA Knee technology. On April 29 and 30, Drs. Levine and Klein successfully performed New Jersey’s first cases of robotic-assisted total knee arthroplasty using the Zimmer Biomet ROSA Knee robot.

Zimmer Biomet’s new robotic knee system has been developed to assist surgeons in optimizing their accuracy and efficiency when planning and performing total knee replacement procedures. The technology allows a personalized surgical plan to be formulated by thoroughly reviewing each patient’s anatomy prior to surgery.

Based on 2D pre-operative X-rays, a very accurate 3D virtual image of the knee is produced and loaded into the computer. At the start of surgery, the surgeon is able to assess the status of the bones and soft tissues of the knee through the robotic interface. The surgeon then utilizes the program’s sophisticated software to formulate a precise surgical plan which, with guidance from the robotic arm, can be confidently and accurately executed during the procedure.
Hackensack University Medical Center is one of three centers in the country utilizing the Zimmer Biomet Knee Robot.
