“Howmedica Triathlon Baseplate Recall: Locking Tabs May Not Engage Properly.” GovInfoNow, updated August 19, 2026. https://govinfonow.com/recall/54089-howmedica-triathlon-baseplate-recall-locking-tabs-may-not-engage-properly. Based on FDA recall #Z-0023-2025 (https://api.fda.gov/device/enforcement.json?search=recall_number:%22Z-0023-2025%22&limit=1).

Why it’s dangerous

The anterior locking tabs on the baseplate may not engage properly with the locking wire of the tib:ibial insert. This could cause the implant to become unstable during surgery or after implantation, potentially leading to joint misalignment or complications.

Who’s affected

Patients undergoing knee replacement surgery using this specific baseplate model are affected. Surgeons and medical staff using the Triathlon Knee System are most at risk during implantation.

How to tell if you have this one

Check for catalog number 5521-B-200 and lot numbers LZX4LB or OLH7VA on the baseplate packaging or device. This product is used in total knee replacement procedures with the Triathlon Knee System.
