Zimmer Biomet received a 510(k) clearance from the FDA for its robotic assistance platform for total knee replacement surgeries.

The Rosa knee system includes three-dimensional, preoperative planning tools, and provides data on soft-tissue and bone anatomy during the procedure to help improve cutting accuracy and implant alignment. It also performs real-time range-of-motion analyses to help balance soft tissue in the joint on a patient-specific basis.

"We are excited for the launch of Rosa Knee, which brings together Zimmer Biomet's robotics technology with our industry-leading knee implants to help surgeons personalize surgical procedures for their patients," Ivan Tornos, Zimmer Biomet’s group president of orthopedics, said in a statement.
