Knee implants

Next to hip implants, knee implants are one of the best-standardized implant groups. The testing required for knee joint devices is summarized in ISO 21536. We offer all relevant testing for TKR as well as individual knee components (tibial, femoral, and patella). Our accredited scope covers static and dynamic fatigue, wear, corrosion, and surface testing. Having tested thousands of knee devices we have accumulated extensive data that helps contextualizing the performance of your novel knee device.
