Howmedica recalls SCORPIO U-DOME PATE: knee replacement implants with part number 73-3508 made over 5 years ago due to potential oxidation in UHMWPE material. Affected units may have reduced durability.
Product manufactured using UHMWPE raw material over 5 years of age has the potential for elevated levels of oxidation. Oxidation within UHMWPE can have an impact on its material properties.
Howmedica is recalling knee replacement implants called SCORPIO U-DOME PATELLA with part number 73-3508 that were manufactured more than 5 years ago. These implants could have elevated oxidation levels in the UHMWPE material, which might affect their long-term durability and performance.
The knee replacement implant uses UHMWPE material that can oxidize over time. Oxidation may weaken the material, potentially reducing the implant's durability and long-term performance. This is a material degradation issue rather than an immediate safety hazard.
Patients who received the SCORPIO U-DOME PATELLA knee replacement implant with part number 73-3508 made more than 5 years ago are likely affected. Those with implants from the listed lot numbers are at the highest risk.
