Discover how we are taking the next steps in orthopedic innovation.



  • First-to-world smart implant that captures key kinematic data metrics
  • The objective kinematic data is an adjunct to other physiological parameter measurement tools applied by the physician during the course of patient monitoring and treatment post-surgery


  • Provides a direct view of patient-specific data for at least ten years
  • Supports the goal of patient compliance


  • The long-term data is automatically available, through a simple to use intuitive interface for both patients and physicians to view on the mymobility® Care Management Platform
  • Maintains standard Persona® Knee surgery workflow and instrumentation


We understand the importance of privacy and are dedicated to protecting that right. We only use customer and patient data to provide the services we’ve agreed upon and for purposes that will enable those services. Persona IQ is not designed to track patient location, and Zimmer Biomet will protect the data you entrust us with through strong safeguards.





System Information

Persona IQ is a first-to-world smart knee implant that captures relevant gait metrics including functional knee range of motion (ROM), step count, and sampled average walking speed. By utilizing sensor-based technology, Persona IQ allows physicians and care teams to collect patient-specific data during the course of patient monitoring.



Average steps taken per minute (steps/minute)



Average Walking Speed

Calculated based on step count and stride length (meters/second)



Stride Length

Calculated based on one gait cycle (meters)



Distance Traveled

Calculated based on step count and stride length (km)


Functional Range of Motion

Including tibia and functional knee ROM (degree)


Qualified Step Count

Number of steps taken during a sampling day

Persona IQ Featuring Canary Quantiles™ Recovery Curves

Recovery Curves enable healthcare professionals to view how a patient’s gait parameter data compares to patients like them. Recovery Curves are overlays of cohort recovery trends for the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentile to benchmark the patient’s individual progress post-operatively.

Recovery Curves are available for the following gait parameters:


  • Walking Speed
  • Functional Range of Motion
  • Qualified Step Count
  • Stride Length
  • Tibial Range of Motion
  • Distance
  • Cadence


Recovery Curves support a deeper and broader analysis of a patient’s recovery when comparing a patient’s gait parameters to the gait parameters of the Canturio™ Tibial Extension (CTE) population of similar age cohort and gender.

Secure Data Flow

The collection and utilization of patient-specific data is easy with Persona IQ. 

The post-operative data is available through a simple to use intuitive interface for both patients and physicians to view on the mymobility Care Management Platform.

Persona IQ with the mymobility Care Management Platform

mymobility provides support and guidance to patients through a connected experience collecting the following metrics. All you have to do is enroll.

  • Education & Engagement
  • PROMs Collection Exceptions (Pain & Gait)
  • Effortless Activity + Physiologic Tracking
  • Pre- and Post-Operative Exercises
  • Telemedicine (Virtual Visits) & Messaging

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.
