What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: This is an FDA Class II recall of a critical medical device (knee implant) with potential for harm. The hazard—UHMWPE material oxidation—could affect implant performance. No illnesses or injuries have been reported, so the severity is capped at High per the rubric criterion for risk-of-harm products without reported injury.

Howmedica Osteonics Corp. is recalling SCORPIO TS TIB INSERT knee replacement implants (Part Number 72-4-7514, Lot Numbers 482LM8 and HH43K7) manufactured with UHMWPE raw material that is over 5 years of age.
