What happened, in plain English

Aesculap is recalling specific knee implant devices (Univation X System) that may loosen over time, potentially requiring revision surgery. This recall affects patients who received these implants and should contact the manufacturer for guidance.

Why it’s dangerous

The implants may loosen over time, which can cause the need for additional surgery to fix the issue. This is a mechanical failure in the implant system that could lead to complications.

Who’s affected

Patients who received the Univation X System knee implants (models NO156Z to NO167Z) are affected. Those with these implants are at risk of needing revision surgery if the implant loosens.

How to tell if you have this one

Check if your knee implant has a catalog code starting with NO156Z through NO167Z. These models were sold as Univation XF Tibia Cemented implants.
