First in New England: Saint Anne’s Hospital Offers “Smart Knee” Joint Replacement

Fall River, MA – Joint replacement surgery has evolved to include some of medicine’s most advanced technologies. Now, an all-new surgical implant using futuristic technology is helping to improve recovery from total knee replacement surgery.

Saint Anne’s is the first hospital in New England to offer the Zimmer Biomet Persona IQ® “Smart Knee.” Formerly available only in academic medical centers, the Smart Knee implant is unique in that it includes software that collects valuable information about the patient’s recovery, activity level, and quality of movement after surgery.

How the Smart Knee Works

In total knee replacement, an artificial implant replicates all the components of a natural knee. The Smart Knee implant adds an important distinction: a special electronic sensor in the stem of the implant that captures important mobility information, such as range of motion, length of stride, walking speed and distance, and even step count. Information is recorded in a secure docking station in the patient’s home and also is available to the surgeon.

The Value of the Smart Knee

Follow-up after any total knee replacement includes scheduled visits to the orthopedic surgeon during the year after surgery. Smart Knee technology takes this one step further by providing ongoing feedback to the patient and their surgeon.

Orthopedic surgeon Colm McCarthy, MD, of SMG Saint Anne's Orthopedics, is the first  surgeon in New England to use the Smart Knee implant. He explains the value of the new technology. 

“The Smart Knee helps the surgeon monitor a patient’s progress, look for trends in critical measurements, such as how well they can bend and flex the knee, and intervene if needed,” says Dr. McCarthy. “It also helps patients watch their progress every step of the way, providing confidence as they recover, or giving them the chance to check in with the surgeon if they have questions or concerns.”

Michael Bushell, president of Saint Anne’s, notes that this newest tool in the surgical toolbox is an example of the hospital’s ongoing commitment to provide advanced care that benefits patients.

“Over the last decade, Saint Anne’s has invested in surgical technologies that have been game changers in orthopedics, spine surgery, and general surgery,” he said. “Patients and surgeons alike love the accuracy, quicker recovery and positive outcomes technology can add to their experience. The new Smart Knee is yet another exciting advancement.”

  • were formerly active
  • are in good health

Protecting Patient Privacy
