Persona IQ® The Smart Knee™

The world’s first smart knee implant

The size, shape, and fit of your knee implants can make a big difference in your satisfaction after total knee replacement. That’s why the Persona Knee was designed to give your surgeon more options to better match your bone’s anatomy.

But, at Zimmer Biomet, we’re never done innovating and transforming what’s possible... for you.  We are proud to introduce the first and only smart knee implant, Persona IQ. Through the latest implant technology, you’ll have confidence that you’re connected to your healthcare team, every step of the way.

How does it work?

Your surgeon will start by selecting Persona Knee implants that best matches your knee’s anatomy. Then, on the bottom portion of the implant, a small “smart” stem extension is attached. This stem contains sensors that capture information like your range of motion, stride length, walking speed, and step count. Other than this small stem extension, the rest of the knee implants are from the Persona Knee line. 

Why is collecting this data important?

The information collected by Persona IQ allows your physician to remotely monitor your functional progress throughout your recovery. Through the latest implant technology, you’ll have confidence that you’re connected to your healthcare team, every step of the way.

What happens next?

If you’re interested in the Persona IQ Smart Knee, talk to your doctor. They can tell you whether or not you’re a candidate for total knee replacement and the Persona IQ Implant.

Indications and Contraindications 


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.

Sounds great, right? Well, what if we told you that Persona IQ is easy to use too!

Persona IQ fits seamlessly into your life. You’ll simply set it up one time. Then, it automatically collects data overnight. This data is sent directly to your surgeon.

Persona IQ collects data on:

  • The range of motion in your knee
  • Your step count
  • Your stride length
  • The distance you walk
  • Your walking speed

Persona IQ does NOT collect data on:

  • Where you’ve been/where you’re going
