The quick read

Ossur recalled its Rheo Knee bionic prosthetic after an internal audit found units were released for distribution without fully going through the assembly process. The device is described as using Artificial Intelligence to adapt to walking style and environment for lower extremity amputations, and customers were told on February 26, 2015 to return units for acceptance testing.

The recall matters because an AI-controlled knee that has not completed assembly and testing could fail to respond correctly to speed, load and terrain changes, creating fall or injury risk for amputees. It remains uncertain how many units were distributed, whether any adverse events occurred, and what the acceptance testing results showed.

Main points
  • Device is identified as RHEO KNEE bionic prosthetic for lower extremity amputations
  • Firm Ossur H F Grjothals 5 Reykjavik Iceland notified customers via phone on February 26, 2015
  • Customers were instructed to send the unit in for service so the Acceptance testing can be performed
Problem

Lower-extremity amputees received Rheo Knee AI prosthetics that had been released without completing the full assembly process, triggering a recall for acceptance testing
