WAILEA, Hawaii — As of March 31, 2023, the American Joint Replacement Registry consists of more than 3.5 million procedures with data submitted across all 50 states and the District of Columbia, according to a presenter here.
“Data completeness is something we audit,” David G. Lewallen, MD, of the Mayo Clinic, said in his presentation on updates from the American Joint Replacement Registry (AJRR) at Orthopedics Today Hawaii. “It is good for most things. There are a few things that are not good, like surgical approach. We are working hard to try to make those better.”
Although the COVID-19 pandemic continues to have an impact on orthopedic procedures, Lewallen said procedural volume has grown 23% during the past year. The 2023 AJRR annual report also showed a decrease in length of stay to 1.2 days, as well as an increase in the use of robotics for total knee and hip arthroplasty.
“Infection is still our most common problem in terms of knee revisions,” Lewallen said, followed by mechanical loosening and other mechanical complications.
Although cementless fixation for primary TKA had a reduced rate of cumulative percent revision for all ages of men, women aged 65 years and older had a significantly increased rate, according to the AJRR annual report. The report showed Medicare patients aged 65 years and older who received a dual mobility THA had a significantly reduced cumulative percent re-revision compared with standard and constrained design implants.
The AJRR annual report also allows surgeons to review revision rates for particular implants, and the collection of patient-reported outcome measures is underway, according to Lewallen.
“The registry has a mechanism for any surgeon who is an academy member to submit topics or ideas for research, and there is potential funding and statistical support for projects that are accepted,” Lewallen said. “I encourage you to look into those possibilities, if you are interested.”
