Howmedica recalls DURATION PLASTIC PATELLA-DURACON knee replacement implants manufactured over 5 years ago due to potential oxidation in UHMWPE material affecting safety.
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 made of DURATION PLASTIC PATELLA-DURACON that are over 5 years old. Oxidation in the plastic material could weaken the implant over time, potentially causing failure.
The plastic material in the implant (UHMWPE) can oxidize over time, especially after 5 years. Oxidation weakens the material, which might lead to implant failure or complications during use.
Patients who received this knee replacement implant from Howmedica over 5 years ago are affected. Those with implants that have been in use for more than 5 years are most at risk.
Check if your knee replacement implant has the product number 6642-2-200 and was manufactured over 5 years ago. The lot number 383541 is associated with this recall.
Verify if your implant was manufactured more than 5 years ago by checking the product number and lot number.
