Use of total ankle arthroplasty (TAA) has been on the rise and researchers from Emory University in Atlanta, Georgia, put the numbers together:
- 41,060 – the number of primary TAAs performed between 2009 and 2019.
- 52.5% – percentage of procedures done in males.
- 136.1% – percentage by which annual volume increased.
- 2,180–5,147 – annual volume increase from 2009 to 2019.
- 120.8% – percentage by which incidence reported per 100,000 population increased.
- 86.6% – percentage by which outpatient procedures increased.
- 242.5% – percentage by which inpatient procedures increased (nearly 3x more than outpatient growth).
- Median length of hospital stay decreased from 3 days in 2009 to 1 day in 2019.
- Incidence grew in patients above the age of 54, with largest growth in those 65–74 years.
- 111.8% – percentage incidence grew in the U.S. South.
- 136.5% – percentage incidence grew in the U.S. West.
The authors concluded that cumulative annual growth rates of TAA were found to be 2 times greater than total knee arthroplasty and 3.6 times greater than total hip arthroplasty.
