HealthEast Community Hip and Knee Replacement Registry

HealthEast Care System began the first community-based joint replacement registry (HJRR) in
the U.S. in 1991, with a database that allowed tracking of implant use and failure rates
among the 90 orthopaedic surgeons performing arthroplasty surgery in the greater
metropolitan area of St. Paul, MN. Initially conceived as part of a process to better manage
costs and determine which implants were most cost-efficient, it became apparent that the
registry would allow insight into the same process that had proven its value in the
Scandinavian joint registries. With the knowledge that a majority of total joint
arthroplasties in the U.S. are performed by relatively low-volume community surgeons, the
HJRR remains uniquely positioned to reflect contemporary U.S. surgical practices.

The purpose of the HJRR is to maintain and improve the care of individuals undergoing joint
replacement surgery by providing timely information to their surgeons and the broader
orthopaedic community. With the primary outcome measure of time to revision surgery,
combined with analysis of confounding factors and mortality monitoring, the HJRR can provide
some realistic measure of the success of a given arthroplasty procedure in our community. In
addition, the registry can evaluate the relative effectiveness of different prosthetic
designs, identify patient variables that may impact implant survival, and provide the
tracking mechanism necessary in the event of implant recalls.

Over the 20 years of its existence, the HJRR has refined its data-gathering, data
verification, and data analysis and utilizes a process design that requires no direct
surgeon involvement with data input. Volunteer surgeons review each revision chart and
operative note to carefully delineate the reason for revision. The HJRR capture process has
been validated and more than 94% of the revision surgery is performed within the HJRR. The
database is used to generate information of practical use to the surgeon, and has been
demonstrated to influence surgeon behavior. Among other examples, HJRR reports on the
failure rates associated with unicompartmental knee arthroplasty, hybrid and cementless
total knee arthroplasty, and metal-on-metal total hip designs have led to significant
declines in their respective use over the periods documented. Similarly, the HJRR allowed
for rapid notification of surgeons and expedited patient care during the three significant
hip implant recalls of the last decade.

As it moves into the third decade, the HJRR is proud of its influential role in the
development of the national American Joint Replacement Registry (AJRR) as one of the
earliest participants and pilot hospitals. It will remain an important contributor to the
larger national effort, particularly for certain data subsets that may be outside of the
scope of the much larger AJRR. The HJRR core workgroup has published widely on its findings
in the last two decades, and looks forward to the future as a compelling example of how
worthwhile information and advancements in orthopaedic science can be made in the community
setting.
