Kirby Medical Center is proud to provide Persona IQ®, the world’s first and only smart knee implant granted De Novo status by the U.S. Food and Drug Administration for total knee replacement surgery. Persona IQ combines the proven1 and trusted knee implant, Persona® The Personalized Knee®, with implantable sensor technology that measures range of motion, step count, walking speed and other gait metrics.

Unfortunately, the knees you’re born with don’t always come with a lifetime warranty, and after years of mobility, your knees begin to wear down and arthritis sets in. This can turn from the occasional ache to pain that makes getting around nearly impossible. In fact, according to the 2021 American Joint Replacement Registry’s Annual Report, over 4.5 million people are living with total knee replacement in the Unites States.

How does the Smart Knee Implant work?

After a total knee replacement, the size, shape and fit of your knee implant can make a big difference in your overall satisfaction. This is why the Smart Knee is designed to give your surgeon more options to better match your bone’s anatomy. Inside your Smart Knee is a stem that captures information like your range of motion, stride length, walking speed and step count. The data that is collected can be accessed by both patient and surgeon and is sent through a HIPPA compliant cloud-based platform. This ensures that you’re connected to your healthcare team every step of the way.

Why Choose Smart Knee?

The Smart Knee Implant combines technology with personal connection. You can rest assured knowing that your personal data is being monitored by your surgeon, eliminating the need for constant follow-up appointments. It supports the goal of 100% patient compliance and provides remote, passively collected data through an intuitive user interface.

The Canary Tibial Extension (CTE) with Canary Health Implanted Reporting Processor (CHIRP) System is intended to provide objective kinematic data from the implanted medical device during a patient’s total knee arthroplasty (TKA) post-surgical care. The kinematic data are an adjunct to other physiological parameter measurement tools applied or utilized by the physician during the course of patient monitoring and treatment post-surgery.

The device is indicated for use in patients undergoing a cemented TKA procedure that are normally indicated for at least a 58 mm sized tibial stem extension.

The objective kinematic data generated by the CTE with CHIRP System are not intended to support clinical decision-making and have not been shown to provide any clinical benefit.

The CTE with CHIRP System is compatible with Zimmer Persona® Personalized Knee System.


The canturio™ te (CTE) is contraindicated for use in patients who are undergoing procedures or treatments at or in the proximity of the CTE using therapeutic ionizing radiation can result in shortened battery life or premature failure of electronic components. Damage to the CTE by therapeutic ionizing radiation may not be immediately detectable.

Before performing TKA on any patient, consider the following contraindications.

The Zimmer Biomet Persona® Knee System is contraindicated for use in patients who have:

  • Previous history of infection in the affected joint and/or other local/systemic infection that may affect the prosthetic joint
  • Insufficient bone stock on femoral or tibial surfaces
  • Skeletal immaturity
  • Neuropathic arthropathy
  • Osteoporosis or any loss of musculature or neuromuscular disease that compromises the affected limb
  • A stable, painless arthrodesis in a satisfactory functional position
  • Severe instability secondary to the absence of collateral ligament integrity

Total Knee Arthroplasty is contraindicated in patients who have rheumatoid arthritis (RA) accompanied by an ulcer of the skin or a history of recurrent breakdown of the skin because their risk of postoperative infection is greater. RA patients using steroids may also have increased risk of infection. Late infections in RA patients have been reported 24+ months postoperative.

Results are not necessarily typical and will vary due to health, weight, activity and other human variables. Not all patients are candidates for this product and/or procedure. Only a medical professional can determine the treatment appropriate for your specific condition. Talk to your surgeon about whether knee replacement is right for you and the risks of the procedure, including the risk of implant wear, infection, loosening, breakage or failure, any of which could require additional surgery. Patients must have a compatible smartphone to utilize mymobility. Not all patients are candidates for mymobility and patients should be evaluated by surgeons as appropriate candidates for therapy at home.
