Smart Knee Implant

Sensor-enabled knee replacement recovery data, explained plainly.

Persona IQ, also known as The Smart Knee, is a Zimmer Biomet knee replacement technology with a smart stem extension that can collect motion data after surgery. For selected patients, that data may help the care team follow recovery trends between visits.

Direct Answer

What is a Smart Knee implant?

A Smart Knee implant is a knee replacement option that includes sensor technology for recovery monitoring. Zimmer Biomet describes Persona IQ as a personalized knee implant with a smart stem extension that collects motion data after knee replacement surgery.

The point is not that the implant does the recovery for you. The point is that the care team may have another stream of objective information, such as movement and range-of-motion trends, to compare with symptoms, therapy progress, office visits, and surgeon instructions.

Important: Smart Knee technology is an option to discuss, not a promise that one implant is best for every patient. Candidacy depends on anatomy, diagnosis, implant choice, privacy preferences, health history, and surgeon judgment.
What It Can Help Show

Recovery data that can make follow-up more specific

01

Motion trends

Sensor-enabled systems can help show how a knee is moving during recovery, including range-of-motion style metrics described by the manufacturer.

02

Walking signals

Gait-related metrics can give the care team another way to understand walking progress alongside therapy notes, symptoms, and office exams.

03

More informed check-ins

Data may help selected patients and care teams have a more specific conversation about recovery progress between scheduled visits.

How To Think About It

Smart technology still sits inside a surgical plan.

Patients should compare the whole knee replacement plan, not just the device name. The surgeon still has to choose the procedure, alignment strategy, implant fit, soft-tissue balance, recovery pathway, and follow-up plan.

1

Diagnosis

Confirm whether knee arthritis, deformity, instability, stiffness, or a prior implant problem is driving the limitation.

2

Fit

Discuss whether the implant system and connected monitoring option fit the patient's anatomy and goals.

3

Privacy

Ask what data is collected, where it goes, who can see it, and how it is protected.

4

Recovery

Use data as one input alongside therapy, symptoms, wound healing, pain control, and surgeon guidance.

Candidacy Signals

When Smart Knee technology enters the conversation

Smart Knee technology is most relevant for patients already considering knee replacement who want to understand whether recovery data could add value to their follow-up plan. It may be especially useful to discuss when a patient values objective progress tracking, is comfortable with connected technology, and is a candidate for the implant system.

It may not fit every surgical plan. Implant selection, bone quality, anatomy, revision needs, medical risk, data-sharing preferences, insurance details, and surgeon experience can all change the recommendation.

Ask during consultation: If I am a candidate for knee replacement, would Persona IQ or another connected implant option meaningfully improve how my recovery is monitored?
Patient Questions

Common questions

Is this the same as robotic knee replacement?

No. Robotic or navigation systems help execute a surgical plan. Smart Knee technology is about collecting selected recovery data after surgery. A patient may hear about both, but they answer different questions.

Does it track where I go?

Zimmer Biomet patient materials state that Persona IQ is not a GPS or location-tracking device. Patients should still ask how data is collected, transmitted, protected, and used.

Will this prevent complications?

No implant can guarantee that. Data can support follow-up conversations, but symptoms, wound checks, urgent concerns, therapy, and office visits still matter.

Is the data a substitute for therapy?

No. Therapy, walking safety, swelling control, range of motion, strength, and surgeon-specific instructions remain central to recovery.
