The ROSA® Knee System from Zimmer Biomet is a robot‑assisted surgical solution for knee replacement (total or partial), designed to customize implant placement to a patient’s unique anatomy. This patient‑video explains what patients can expect — from preoperative planning and imaging, through surgery with robotic guidance, to postoperative recovery — illustrating how ROSA uses advanced measurements and soft‑tissue assessment to guide precise bone resections and balanced implant alignment. The video aims to reassure patients by clarifying the procedure, showing how surgeon expertise is combined with robotic assistance to improve accuracy and potentially enhance outcomes, function, and recovery. It helps patients understand how ROSA differs from conventional knee replacement methods and the potential benefits of robot‑assisted surgery.
