Knee replacement surgery used to mean getting a new joint and hoping for the best. Today, thanks to technology like the Smart Knee® implant and Persona IQ® system by Zimmer Biomet®, your new knee can actually communicate data to your doctor, even from home. Here's everything you need to know, in plain English.
Smart Knee® Implants Explained: A Smarter Way to Track Recovery
Think of a Smart Knee® implant like a fitness tracker, but built right into your knee replacement. It's a standard knee implant with a tiny sensor inside. According to Zimmer Biomet®, that sensor quietly tracks things like:
- How far you can bend your knee
- How many steps you're taking each day
- How active you are during recovery
All of this happens automatically. You don't press any buttons or wear any extra devices. Your knee just does it on its own.
How Persona IQ® Smart Knee® Technology Tracks Your Recovery 24/7
Persona IQ® is the specific Smart Knee® system made by Zimmer Biomet®. It is one of the first FDA-cleared smart implant systems that collects real recovery data from inside your knee, every single day.1
Here's how it works:
- You get your knee replacement as normal
- The Persona IQ® sensor inside starts collecting data right away
- That data is sent securely to your surgeon's office
- Your doctor can see how your knee is actually doing, not just how you feel on your best day in the office
Real-Time Recovery Tracking: A Game Changer After Knee Replacement
With traditional knee replacement recovery, your surgeon mostly has to rely on what you report between appointments. They ask you questions. You answer. But what happens on a Tuesday afternoon when you're at home and struggling? They don't know unless you call.
Recent research published in Sensors found that remote patient monitoring after knee arthroplasty using sensors to track mobility, range of motion, and movement patterns shows promise as a scalable way to assess how patients are recovering in real life, outside of clinic visits.2 With a Smart Knee® implant, your care team gets real numbers, not just your best recollection. That means:
- Problems get caught earlier before they become bigger issues
- Your rehab plan gets adjusted based on what's actually happening
- You feel more confident knowing your progress is being monitored
- Fewer guessing games at follow-up visits
Is a Smart Knee® Implant Right for You?
A Smart Knee® implant could be a great fit if you:
- Want to stay closely connected with your doctor during recovery
- Like seeing data about your own health and progress
- Are active and want to return to walking, hiking, or everyday activities as safely as possible
- Want peace of mind during what can be a stressful recovery period
Shared decision-making between patients and surgeons, including discussions about new technologies, leads to better satisfaction and outcomes after joint replacement surgery. Your doctor will help decide if Persona IQ® technology is the right choice based on your health, your goals, and your lifestyle.
Benefits of Persona IQ® Technology at a Glance
| What It Does | Why It Helps You |
|---|---|
| Tracks steps & movement daily | Shows real recovery progress |

A Smart Knee® implant is simply a knee replacement that keeps your doctor in the loop every day, not just at checkups. Persona IQ® technology by Zimmer Biomet® makes that possible by placing a small, smart sensor inside your implant. It quietly collects the data so you can focus on getting better.
Frequently Asked Questions (FAQs)
What is a Smart Knee® implant in simple terms?
It's a knee replacement with a built-in sensor that automatically tracks your recovery and shares that information with your doctor. Zimmer Biomet® describes the Persona IQ® system as designed to provide continuous, passive data collection without any effort from the patient.1
Is the Persona IQ® system safe?
Yes. Persona IQ® by Zimmer Biomet® has received FDA clearance and meets the same rigorous safety standards as traditional knee implants, with the added benefit of smart monitoring technology.2
Do I have to do anything to make it work?
No. The sensor collects data on its own. There's nothing to charge, activate, or wear.¹
Can I see my own recovery data?
Yes. You and your care team can both view your recovery metrics through a secure digital platform provided as part of the Persona IQ® system.1
Does having a smart implant make surgery more complicated?
Not significantly. The procedure is very similar to a standard knee replacement your surgeon simply uses the sensor-enabled Persona IQ® implant.
How long does the smart sensor last?
The implant itself is built to last for the long term. The sensor is designed to support monitoring through your most important recovery period.
