Zimmer Biomet on March 10 issued an urgent field safety notice to European hospitals requesting the removal of the company's StageOne and StageOne Select bone cement spacer molds.
The notice intends to prevent the use of some implants, which may have been improperly cleaned and monitored.
Zimmer Biomet received five complaints that may be linked to the issue, which could result in an adverse local tissue reaction, pains and potential reactions to allergens or toxins.
More than 230,000 implants have been distributed.
Zimmer Biomet did not respond to a request for comment March 18.
