Innovative knee-replacement technology makes debut at Essentia Health-Fargo

An exciting advancement in orthopedic surgery has officially been introduced at Essentia Health-Fargo. On Wednesday, July 13, orthopedic surgeons Dr. Sam Lindemeier and Dr. Roxanne Keene successfully completed the hospital’s first knee-replacement surgery using Zimmer Biomet’s new ROSA (robotic surgical assistant) Knee System.

This surgical procedure is like traditional total knee replacement, but with a robotic assistant. The ROSA Knee System uses data collected before and during surgery to inform the surgeon(s) about details related to the patient’s unique anatomy that may affect the implant fit. By using this real-time data, the surgeon can plan for and carry out a personalized surgery based on that patient’s individual needs.

“Everyone has their own unique anatomy, which is why we are proud to introduce new technology at Essentia Health-Fargo that offers a more personalized approach to total knee-replacement surgery,” said Dr. Lindemeier and Dr. Keene. “This advancement in orthopedic surgery allows for more accuracy when placing the implant, improving on an already successful surgery.”

Prior to the surgery, patients will have a series of X-rays performed, which are used to create a 3D model of their knee. During the surgery, the system uses a camera and trackers to provide the surgeon with data about the patient’s knee. All this information about the patient’s unique anatomy, combined with the surgeon’s expertise, helps them know how to precisely position the implant.

The ROSA Knee System does not make movements unless prompted by the surgeon. The surgeon has been specifically trained to use the system and remains in control of making all the decisions based on the data provided.

Knee-replacement surgery using the ROSA Knee System may be recommended for patients diagnosed with osteoarthritis who have knee pain, swelling, stiffness and decreased flexibility despite undergoing conservative treatment.

Osteoarthritis, the most common form of arthritis, is a wear-and-tear condition that destroys joint cartilage and bone. It typically develops after years of constant motion and pressure in the joints. As the cartilage continues to wear away, the joint becomes increasingly painful and difficult to move.
