Insights
Revision total hip arthroplasty (rTHA) for instability is increasing in the U.S. This trend highlights the need for cost-effective strategies and improved surgical techniques to manage rising patient numbers and healthcare costs.
Area of Science:
- Orthopedic surgery
- Arthroplasty research
- Health economics
Background:
- Instability is a common complication following total hip arthroplasty (THA), leading to patient morbidity and dissatisfaction.
- The national incidence of THA instability remains poorly defined despite advances in implants and techniques.
- Rising THA rates necessitate understanding the impact of instability.
Purpose of the Study:
- To characterize the contemporary volume of revision THA (rTHA) for instability in the U.S.
- To analyze the economic impact of rTHA for instability.
- To project future trends in rTHA for instability.
Main Methods:
- Utilized two national databases to identify inpatient and outpatient rTHA cases for instability (2012-2022).
- Excluded cases involving periprosthetic joint infection.
- Modeled projected rTHA volumes to 2035 using linear and Poisson regression.
Main Results:
- rTHA for instability cases increased from 9,870 (2012) to 16,228 (2022), projected to reach 28,830 by 2035.
- Average patient costs rose from $12,540 (2012) to $18,334 (2022), projected to hit $25,612 by 2035.
- Annual hospital charges increased from $138 million (2012) to $294 million (2022), projected to reach $533 million by 2035.
Conclusions:
- National volume and economic burden of rTHA for instability are increasing.
- Projected rTHA volumes nearing 30,000 cases by 2035 warrant attention.
- Surgeons must consider cost-effective strategies and optimized techniques to mitigate instability risks.
Background:
Instability remains one of the most common complications after total hip arthroplasty (THA) and is a notable cause of patient morbidity, pain, and dissatisfaction. Despite advances in implant technology and surgical techniques, the national incidence of instability after THA remains poorly defined. As THA continues to rise, our study aimed to characterize the contemporary volume and economic impact of revision THA (rTHA) for instability in the United States (U.S.).
Methods:
There were two national databases that were queried to identify inpatient and outpatient rTHA cases for instability between 2012 and 2022. Exclusion criteria included patients who presented with a periprosthetic joint infection. The national volume of rTHA for instability was calculated, and projected volumes of rTHA for instability were modeled using linear and Poisson regression to 2035.
Results:
In 2012, there were 9,870 cases of rTHA for instability in the United States, which increased to 16,228 in 2022. By 2035, it is projected that there will be 28,830 cases of rTHA for instability. The average patient costs of rTHA for instability increased from $12,540 to $18,334 from 2012 to 2022. By 2035, patient costs are projected to reach an average of $25,612. The annual cumulative hospital charges increased from $138 million in 2012 to $294 million in 2022. Based on this rate, cumulative hospital charges are expected to increase to $533 million by 2035.
Conclusions:
Our study demonstrated that the national volume and economic impact of rTHA for instability continue to rise, with a projected volume approaching 30,000 cases by 2035. Surgeons should be aware of these growing trends, as they emphasize the need for cost-effective care strategies and optimized surgical techniques to mitigate further risks of instability.
Level Of Evidence:
Level III retrospective cohort.
