Event Description
|
It was reported that during knee arthroplasty, the surgeon opted to utilize a size 3 tibial tray and a size e femoral component.At the time, the surgeon did not realize that the size e articular surface was not compatible with the size 3 tibial tray.After the implants had been placed, there appeared to be a few millimeters of overhang on both the medial and lateral side.In order to reduce the overhang and the risk of impingement, a smaller size d articular surface was used instead.However, it was identified after the procedure that the smaller articular surface was not compatible with the femoral component.Attempts have been made, however, no additional information is available at this time.

This follow-up report is being submitted to relay additional information.The following sections were updated: b4; b5; g3; g6; h1; h2; h3; h6.No product was returned or pictures provided; visual and dimensional evaluations could not be performed.The dhr was reviewed and no discrepancies relevant to the reported event were found.X-ray was provided but not reviewed.The root cause of the reported issue is attributed to user error as the surgeon used incompatible implants.Per package insert, to properly match the components, the femoral and tibial component size must both be reflected on the articular surface label.Mismatching may result in poor surface contact and cause pain, greater wear, implant instability, or otherwise reduce implant life.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
