First AI tool For Post-op Predictions Rolled Out By Zimmer Biomet

Having cleaved off its spinal and dental businesses to nascent independent company ZimVie, medical device company Zimmer Biomet is now focusing all its energy towards the remaining orthopaedic segments, which include the hip and the knee.

The first move post-spinoff covers the knee and hip surgical businesses, and the company has launched its first software offering based on artificial intelligence.

It’s called the WalkAI tool, and is built to analyse the patient’s progress in the first few months following hip or knee surgery, with the aim of making a prediction on whether or not they’re recovering at the expected pace.

It has already been offered to some current users of Zimmer Biomet’s care management platform Mymobility, and will extend to a wider release by the end of the month.

WalkAI connects to Mymobility, which constantly collates data from the Apple Watches and iPhones of post-op patients regarding their gait, along with numerous other physiological metrics. An AI algorithm then analyses this mobility data to predict the walking speed of the patient as far as 90 days following surgery.

If these daily predications are falling short of the real-world data kept in Zimmer Biomet’s database, WalkAI is built to send an automatic notification to the healthcare providers of the patient through Mymobility, which can only be accessed by the clinician-facing side of the platform. WalkAI alerts them to the possibility that the patient may not be on target for recovery, giving the clinicians the option of tweaking the recovery before it veers too far off track.

“Using a proprietary, Zimmer Biomet-developed artificial intelligence algorithm, WalkAI is the orthopedic industry’s first and only AI-based model to create daily, personalized predictions and identify patients who may be exceptions to typical recovery curves in an effort to help surgeons mitigate or minimize poor outcomes,” said Liane Teplitsky, president of global robotics and technology and data solutions at Zimmer Biomet.

“WalkAI is built from our wealth of anonymized ZBEdge data and is the first model to demonstrate our unique capability to deliver actionable predictions by connecting real-world data and AI through ZBEdge products and experiences,” Teplitsky said.

The software is going to be included in Zimmer Biomet’s ZBEdge suite, which launched last year. It combines digital health, robotic surgery, and app solutions for smartphones, which collaborate to form a highly comprehensive platform for digital surgery.
