Why Have a Joint Registry?

1) Reduce Complications and Revision Rates

2) Monitor and Support Implant Recalls and/or Advisory Notices

3) Improved Orthopaedic Patient Care

When hospitals and surgeons actively utilize the knowledge gained from the data – it is the patients who benefit the most.

A Growing Network

Number of hip and knee replacement procedures tracked:

200000 and counting...


623 hospitals participating.


4,504 Surgeons

50 States Represented


By the Numbers...

Hip and knee implants account for more than 85% of the joint reconstruction and replacement market.

More than 7 million Americans have had a knee or hip replacement surgery.

Joint registries demonstrate up to a 50% reduction in revision rates after registry initiation and identification of best practices.

If U.S. revision rates were cut by just 2%, Medicare could save more than $65 million.
