The American Academy of Orthopaedic Surgeons (AAOS) has announced the completion of a report for patient use based on data from the largest orthopedic registry in the world—the American Joint Replacement Registry (AJRR). This latest report for the general public contains clinical data from hip and knee arthroplasty patient outcomes. The report is derived from the sixth AJRR Annual Report on hip and knee arthroplasty data, and covers the information that is most relevant for patients and the public.

As for what makes AJRR the pre-eminent orthopedic registry, William J. Maloney, M.D., chair of the AAOS Registry Oversight Committee, told OTW, “Our registries are led by a broad group of stakeholders, including representatives from the orthopaedic surgeon community, hospitals, private payers, and the public. Recognizing the importance of public participation, we created the Public Advisory Board (PAB), whose mission is to ensure a public voice in the AAOS Registry Program’s data collection, reporting, and utilization activities. It was through the recommendation of this group that we created a version of our AJRR Annual Report that can be easily digested by the public. This is our fourth version of the report and our registry participants have expressed a positive interest in the report.”
Dr. Maloney continued to explain how the report will be distributed, saying, “The distribution of the report is done digitally—we share it on our patient-facing website OrthoInfo.org which gets approximately 30 million visitors a year, as well as on our profession-facing website aaos.org which can be accessed by our registry participants and used within their own patient education activities.”
“We utilize our own metric reporting to gauge how many downloads we get of the report—from previous years, we know that more than 1,700 people accessed the information in the past. We also share it with those organizations that have a direct interest in educating the public about the importance of data and registry science.”
The new report features:
- Illustrated overviews of both hip and knee replacements
- Hip and knee procedure trends (data from 2012 through 2018 including more than 1.5 million procedures from 1,302 institutions across the United States)
- Detailed explanation about diagnosis and reasons for revision surgery.

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
