The AAOS Registry Program User Group Network

The Registry Program User Group Network (Unet) provides all Registry Program participants with the opportunity to interact with each other and share ideas about the collection of orthopaedic procedure data. With nearly thousands of participating sites (hospitals, health systems, surgery centers, and private practice groups), we strive to create an environment within the orthopaedic community that fosters conversation about best practices and ways to improve Registry implementation and processes within health care sites. Registry Program participants can participate in regular Unet webinars and help shape the orthopaedic registry community through their insights and contributions.

Unet Webinars

AAOS Registry Program staff holds quarterly webinars for Unet members. Topics typically covered include recent Registry enhancements, data submission process updates, and more. Email invites are sent to all participants and information is contained within our e-newsletters.

Slides and recordings from Unet webinars can be found in the Tools & Resources section of the RegistryInsights® platform.

In-Person Unet Meeting

An in-person Unet meeting is held each year during the AAOS Annual Meeting in March. A dial-in option is offered for those who can't attend in-person.

Slides and recordings from previous In-person Unet Meetings can be found in the Tools & Resources Section of the RegistryInsights platform.
