The case seeks expert opinion on the importance of following correct packaging procedures for medical devices, particularly when dealing with oxidative materials like polyethylene.

Questions to the Medical Device expert and their responses


Please provide examples of your professional background in medical device packaging.

I have over 20 years’ experience in the medical device industry, focusing on regulatory compliance and quality assurance aspects. My work involves adhering to packaging and other types of standards during the manufacture and packaging of orthopedic devices.


What is the proper way to package a medical device made of polyethylene to prevent oxidation?

To ensure optimal oxidation protection, it is crucial to follow FDA-recognized ASTM packaging standards, including ISO 11607-1. Depending on the specific materials used in the device, other standards may also be applicable. If a device is not packaged correctly, it can lead to issues like oxidation, which can compromise its functionality and safety.

Additionally, if the tibial insert was oxidized due to faulty packaging, the device may not have been properly sterilized either.
