AJRR Is Now a Qualified Clinical Data Registry (QCDR)​​

AJRR was recently approved by the Centers for Medicare & Medicaid Services to be a QCDR.  One of the requirements for all QCDRs is that they must publically post the detailed specifications of the quality measures we collect in order to ensure transparency of information to the public.  Please click button below for more information.

The photo above shows the construction of the new AAOS Building as of August 2, 2014. AJRR will be on the second floor.

Increasing Use of Total Knee Replacement and Revision Surgery
In this issue of JAMA, Cram and colleagues report detailed analysis of primary and revision total knee replacement (TKR) performed on more than 3.2 million Medicare beneficiaries from 1991 to 2010. This analysis confirms and quantifies several important findings. First, the use of primary and revision TKRs in Medicare beneficiaries has increased both in absolute volume from 93,230 procedures in 1991 to 226,177 procedures in 2010 and in per capita usage. Second, the pattern of care has changed substantially.  Read more....
