DALLAS — The American Joint Replacement Registry, which is the official registry of the American Association of Hip and Knee Surgeons, includes data about infection and revision procedures for dislocation and instability of hips for the first time in 2019. In addition, in terms of primary total knee arthroplasty, which the report noted constituted 55.1% of all total joint arthroplasty procedures performed from 2012 to 2018, the report included further analyses of cemented vs. cementless fixation.

The American Joint Replacement Registry (AJRR) annual report was released in conjunction with the first day of the AAHKS Annual Meeting and includes findings from 1,525,435 hip and knee arthroplasty procedures performed between 2012 and 2018, according to a press release.

In giving an update on the registry and its latest report to meeting attendees, Kevin J. Bozic, MD, MBA, chair of AJRR Steering Committee, said the 2019 registry contents represent “over 1,200 sites of service and almost 8,500 surgeons and that is almost 30% growth over last year.”

The report contains descriptive statistics that address utilization in the United States, according to Bozic, who previewed the hip arthroplasty findings saying, “This shows you that 36-mm heads continue to be the most common head utilized and that is going up.”

Furthermore, “there is a slight increase in the number of dual mobility heads going in,” he said.

Concerning knee arthroplasty, “there is a small, but [an] increase in the number of cementless knees being done throughout the country. Again, when we link that up with Medicare claims data, at least out to 6 years now, we see no difference in survivorship between cemented and cementless. So, that is encouraging compared to prior generation experience,” Bozic said.

The AJRR report aims to provide valuable information to orthopedic surgeons, hospitals, ASCs, device manufacturers, payers and patients, according to the release. – by Susan M. Rapp
