ODIN is a collaborative group of centres with an interest in periprosthetic joint infections. It encompasses surgeons, infectious disease physicians, nurses, researchers and pharmacists.

Research aimed to decrease the burden of prosthetic joint infections (PJI) has been hampered by heterogenous retrospective data and small data-sets. It is our belief that to be able to advance PJI research we must rethink how we collect data and collaborate. We believe that bigger data-sets are required, that are comprehensive, accurate, uniform and prospective. Collection of uniform data would allow global collaboration.

To achieve this goal The Orthopaedic Devices Infection Network (ODIN) has been established. ODIN is an international collaboration between centres specializing in the management of prosthetic joint infections (PJIs), with the legal and ethical framework to allow international collaboration.

A primary aim of the network is to establish a global comprehensive database of PJIs to help answer questions that would benefit from large datasets.

ODIN began through a round-table discussion surrounding PJIs. The current literature regarding PJIs is heterogeneous. PJIs can also be considered rare but devastating events. The combination of these factors lead to the recognition of the need for international collaboration to allow meaningful conclusions through the analysis of large cohorts. This lead to reaching out to centres with an interest in PJIs and an agreement to combine resources to tackle PJI research resulting in ODIN.

The primary aim of ODIN is to improve periprosthetic joint infection prevention, diagnosis and management through evidence based research using "big-data": a large registry of homogenous PJI data.
