NORE Online Survey on systematic collection of radiological data in arthroplasty registries or single centres in Europe

1. SYSTEMATIC DATA COLLECTION

50% of survey complete.

Dear Colleague,

Imaging is the most efficient diagnostic tool to monitor implant performance and detect early signs of failure in the area of joint replacement. Since imaging abnormalities often precede the appearance of clinical signs and symptoms and always precede revision surgery - up to many years – they are an appropriate surrogate marker of failure. Better use of the information of existing imaging series (especially serial radiographs) and inclusion of systematic early imaging combined with clinical symptoms in post-marketing surveillance protocols of new implants has the potential to improve and speed up the detection of inferior implants. Moreover, artificial intelligence based tools may facilitate some of the steps in imaging analysis.

To better understand the current situation in Europe and potentially create an informal network of people working/interested in this area we kindly ask you to complete this survey.

Best wishes,
